Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The embodiment of the invention provides a method for monitoring the running state of a Nginx network isolation space, which can be applied to a server for providing Nginx service in a cloud computing system, wherein the server can be provided with a user mode protocol stack based on DPDK or other technologies, and the server can process received user messages through a Nginx program running on the user mode protocol stack. A keepalive process for detecting the service state of the Nginx may also be run on the server, and specifically, the server may monitor the running state of each network isolation space inside the Nginx process based on the user mode protocol stack through the keepalive process. The server may include a processor, a memory, and a transceiver, where the processor may be configured to perform the method for monitoring the operation status of the Nginx network isolation space in the following process, the memory may be configured to store data required and generated in the following process, and the transceiver may be configured to receive and transmit related data in the following process.
The following will describe in detail a process flow of the method for monitoring the operation status of the nginnx network isolation space shown in fig. 1 with reference to the specific embodiment, which may be as follows:
step 101: a plurality of network isolation spaces are created inside a locally running Nginx process based on a user mode protocol stack.
In implementation, a Nginx program may be installed on a server, and the Nginx program may perform various business processes on a user mode protocol stack of the server, so that the server can serve as a web server, a reverse proxy server or an email proxy server to provide a Nginx service for a user in a cloud computing system. When the Nginx program is started for the first time or restarted due to a fault, the server can run the Nginx process locally, and a plurality of network isolation spaces are created in the Nginx process based on a user mode protocol stack. Here, the specific number of the network isolation spaces may be preset on the server by the administrator, or may be automatically recorded by the server according to the number of the network isolation spaces used by the previous Nginx program run. If the number of the actually required network isolation spaces is larger than the number of the set network isolation spaces, the network isolation spaces can be additionally arranged at any time in the running process of the Nginx program.
Step 102: and creating a corresponding virtual interface for each network isolation space through the Nginx process.
In implementation, after the server creates a plurality of network isolation spaces inside the Nginx process, an independent virtual interface can be created for each network isolation space through the Nginx process, and each virtual interface corresponds to one network isolation space. The virtual interface can be used for at least monitoring the state, the running state of each network isolation space corresponds to the interface state of the virtual interface, and when the running state of the network isolation space is normal, the state of the corresponding virtual interface can be 'up'; when the operation state of the network isolation space is a fault, the state of the corresponding virtual interface may be "down".
Step 103: and monitoring the virtual interface corresponding to each network isolation space through a Keepalived process operated by the local machine.
In implementation, after the server creates the virtual interface through the nginn process, the keepalive process may be started, and the virtual interface corresponding to each network isolation space may be provided to the keepalive process through the nginn process. Then, as shown in fig. 2, the server may monitor the virtual interface corresponding to each network isolation space through a locally run Keepalived process.
Step 104: and determining the running state of the network isolation space corresponding to each virtual interface through a Keeplived process based on the state of each virtual interface.
In implementation, after the server monitors the state of each virtual interface through the keepalive process, the server may determine, through the keepalive process, an operating state of the network isolation space corresponding to each virtual interface based on the monitored state of each virtual interface. Taking a virtual interface monitored by the Keepalived process as an interface 1 as an example, assuming that the state of the interface 1 is "up", the server can determine that the running state of the network isolation space corresponding to the interface 1 is normal through the Keepalived process; assuming that the state of the interface 1 is "down", the server may determine that the operation state of the network isolation space corresponding to the interface 1 is a fault through the Keepalived process.
Optionally, a server architecture of the primary/secondary server may be used to provide an external Nginx service, and correspondingly, the method for monitoring the operation state of the isolated space of the Nginx network may be simultaneously applied to the primary/secondary servers corresponding to each other, where the processing of step 101 may be as follows: the main/standby server creates a network isolation space corresponding to each user in a locally operated Nginx process based on a user mode protocol stack according to preset Nginx configuration files of a plurality of users.
In the implementation, as shown in fig. 3, in consideration of the situation that a network isolation space inside a single server provides a network service for a user, when the server fails, a nginnx service cannot be continuously provided for the user, and thus the quality of the network service is affected, for this reason, a technician of an internet service provider may provide the nginnx service based on a main/standby server architecture and simultaneously apply the processing of the above steps 101 to 104 to the main/standby servers corresponding to each other. For the step of creating the network isolation space, a technician of an internet service provider may set a Nginx configuration file corresponding to each user in a master/standby server, and the master/standby server may load the Nginx configuration file corresponding to each user through a locally operated Nginx process, respectively, so as to create the network isolation space corresponding to each user inside the Nginx process. It can be understood that the number of the network isolation spaces created on the primary/secondary server is consistent, and the network isolation spaces are in one-to-one correspondence with the primary and secondary servers.
Optionally, the master/standby server may configure a different virtual IP for each network isolation space to provide an Nginx service for different users, and accordingly, after step 101, the following processing may be performed: the master/standby server configures a virtual IP corresponding to each user for each network isolation space; and the main server provides Nginx service for each user through each network isolation space created by the main server locally based on the virtual IP corresponding to each user.
In implementation, after the host/standby server creates a plurality of network isolation spaces in an Nginx process based on a user mode Protocol stack, a configuration file of a keepalive process may be set, where the configuration file of the keepalive process may include various types of configuration information such as global configuration information and VRRP (Virtual Router Redundancy Protocol) configuration information. The global configuration information may include information such as a recipient address of the VRRP packet and a server identifier under the primary/backup server architecture. The VRRP configuration information may include configuration information such as a VRRP synchronization group, a VRRP _ instance (hereinafter, referred to as a VRRP group), and the like, where the VRRP synchronization group may include information such as an identifier of each VRRP group and an execution script when the master/backup state is switched, and the VRRP _ instance may include information such as an initial state of a server, a source address for sending a VRRP packet, a priority of the server, and a virtual IP corresponding to each user. Then, the primary/standby server may configure a virtual IP corresponding to each user for each network isolation space based on the configuration file of the keepalive process. Then, the server can determine a main server and a standby server through the keepalive process based on different priorities of different servers, the main server allocates the virtual IP corresponding to each user to the corresponding network isolation space through the keepalive process, and provides the Nginx service for the corresponding user through the corresponding network isolation space based on the different virtual IP corresponding to each user.
Optionally, the server may divide the multiple network isolation spaces into one VRRP group, and accordingly, the process of creating the network isolation space may specifically be as follows: dividing a plurality of users into a plurality of VRRP groups through a Nginx process operated by a local machine; for each VRRP group, configuring Nginx configuration files of all users included in the VRRP group into the VRRP group in a linked list form; and according to the Nginx configuration files of all users in each VRRP group, creating a network isolation space of each VRRP group in the Nginx process based on a user mode protocol stack.
In implementation, when the server creates a network isolation space inside a locally running Nginx process based on a user mode protocol stack, all users may be grouped first. Specifically, the server may divide all users into a plurality of VRRP groups through a locally run Nginx process, and each VRRP group may be divided into one or more users. Then, the server can configure the Nginx configuration files of the users included in each VRRP group into the corresponding VRRP group in a linked list mode. If six users, namely user A, user B, user C, user D, user E and user F, exist in total, the server can divide the users into two VRRP groups, for example, user A, user B and user C correspond to the VRRP group 1, user D, user E and user F correspond to the VRRP group 2, then the server can configure the Nginx configuration files of each user A, user B and user C into the VRRP group 1 in a chain table mode, and configure the Nginx configuration files of user D, user E and user F into the VRRP group 2 in a chain table mode. Then, the server can load all the configuration files of the users in each VRRP group through the Nginx process, and then create the network isolation space included in each VRRP group inside the Nginx process based on the user mode protocol stack according to the Nginx configuration files.
Optionally, the main server may notify the running state of the network isolation space on the standby server in a manner of sending a VRRP packet to the standby server, and if the standby server does not receive a VRRP packet of a certain network isolation space sent by the main server for a certain duration, it may be determined that the network isolation space on the main server fails, and accordingly, after step 104, the following processing may be performed: if the running state of the target main isolation space is normal, the main server periodically sends a target VRRP message corresponding to the target main isolation space to the standby server through a keepalive process running by the local machine; if the running state of the target main isolation space is a fault, the main server stops providing the Nginx service for the target user corresponding to the target main isolation space through the target main isolation space and stops sending a target VRRP message to the standby server; and if the target VRRP message is not received within the continuous preset time, the standby server determines a target standby isolation space created by the local machine corresponding to the target VRRP message, and provides Nginx service for a target user corresponding to the target main isolation space through the target standby isolation space based on the virtual IP corresponding to the target main isolation space.
In implementation, when the master server monitors that the state of the virtual interface corresponding to a certain network isolation space (which may be referred to as a target master isolation space) is "up" through the keepalive process, that is, the state of the target master isolation space is normal, the master server may generate a VRRP message (which may be referred to as a target VRRP message) corresponding to the target master isolation space through the keepalive process executed by the master server, where the target VRRP message may carry information such as an execution state of the target master isolation space and a space identifier of the target master isolation space, and periodically (e.g., every 1 second) sends the target VRRP message to the standby server. When the master server monitors that the state of the virtual interface corresponding to the target main isolation space is down through the keepalive process, that is, the state of the target main isolation space is a fault, the master server stops providing the Nginx service for a user (which may be called a target user) corresponding to the target main isolation space through the target main isolation space, and does not send a target VRRP message to the standby server through the keepalive process operated by the local server.
The standby server can record the current receiving time each time when receiving the target VRRP message corresponding to the target main isolation space, and if the standby server does not receive the target VRRP message within the preset time after receiving the target VRRP message, the standby server can determine the target standby isolation space created by the local machine corresponding to the target VRRP message, and then provide Nginx service for the target user through the target standby isolation space based on the virtual IP corresponding to the target main isolation space. Meanwhile, the standby server can also periodically send the VRRP message corresponding to the target standby isolation space to the main server through the Keepalived process operated by the local machine.
Optionally, when the server divides a plurality of network isolation spaces into one VRRP group, the main server may notify the standby server of the operating status of each network isolation space in the VRRP group by sending a VRRP group message to the standby server, and if the standby server does not receive a certain VRRP group message sent by the main server for a certain duration, the standby server may determine that a faulty network isolation space exists in the corresponding VRRP group on the main server, and accordingly, after step 104, the following processing may be performed: if the running states of all network isolation spaces in the target main VRRP group are normal, the main server periodically sends a target VRRP group message corresponding to the target main VRRP group to the standby server through a keepalive process operated by the local machine; if the target main VRRP group has a network isolation space with a fault operation state, the main server stops providing Nginx services for all users corresponding to the target main VRRP group through all network isolation spaces in the target main VRRP group, and stops sending a target VRRP group message to the standby server; and if the standby server does not receive the target VRRP group message within the continuous preset time, determining the target VRRP group created by the local machine corresponding to the target VRRP group message, and providing Nginx service for all users corresponding to the target main VRRP group based on all network isolation spaces in the target VRRP group.
In implementation, when the master server monitors that the states of the virtual interfaces corresponding to all the master isolation spaces in a certain VRRP group (which may be referred to as a target master VRRP group) are "up" through the locally run Keepalived process, the master server may determine that the running state of the target master VRRP group is normal. At this time, the master server may generate a VRRP group packet (which may be referred to as a target VRRP group packet) corresponding to the target master VRRP group through a keepalive process run by the local server, that is, one VRRP group corresponds to one VRRP group packet, and when a plurality of users are divided in one VRRP group, that is, a plurality of network isolation spaces are divided in one VRRP group, the number of VRRP packets may be effectively reduced. Then, the main server may periodically send the target VRRP group packet to the standby server, where the target VRRP group packet may carry at least the identification information of the target main VRRP group. When the main server monitors that the state of the virtual interfaces corresponding to one or more network isolation spaces in the target main VRRP group is down through the Keepalived process operated by the local machine, the main server can determine that the network isolation space with the fault operation state exists in the target main VRRP group. At this time, the master server may stop providing the Nginx service for the user through all the network isolation spaces in the target master VRRP group, and no longer send the target master VRRP group message to the standby server through the Keepalived process run by the local server.
The standby server can record the current receiving time each time when receiving the target VRRP group message, and if the standby server does not receive the target VRRP group message continuously within the preset time after receiving the target VRRP group message, the standby server can determine the target VRRP group created by the local machine corresponding to the target VRRP group message, specifically, the standby server can obtain the identification information of the target main VRRP group carried by the target VRRP group message through a keepalive process operated by the local machine, and then determine the target VRRP group created by the local machine corresponding to the target VRRP group message according to the identification information. And then, the standby server can provide the Nginx service for all target users corresponding to the target main VRRP group based on all network isolation spaces in the target standby VRRP group. Meanwhile, the standby server can also periodically send the VRRP group message corresponding to the target standby VRRP group to the original main server through the Keepalived process operated by the local machine.
In the embodiment of the invention, a plurality of network isolation spaces are established in the locally operated Nginx process based on a user mode protocol stack; creating a corresponding virtual interface for each network isolation space through the Nginx process; monitoring a virtual interface corresponding to each network isolation space through a Keepalived process operated by the local machine; and determining the running state of the network isolation space corresponding to each virtual interface through a Keeplived process based on the state of each virtual interface. Therefore, a virtual interface is created for each network isolation space in the Nginx process, and the running state of each network isolation space is determined by monitoring the state of the virtual interface, so that the running state of each network isolation space in the Nginx process can be effectively monitored under a user mode protocol stack.
