Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, a Network File System (NFS) according to an embodiment of the present invention is provided with a server 11 and a plurality of hosts 12, where each host 12 can access a resource in the server 11, the server 11 can provide one service directory or a plurality of service directories, and each host 12 can access a resource in one service directory of the server 11 or a plurality of service directories of the server 11, which may be determined according to actual conditions. When the server 11 provides a plurality of service directories, the resources stored in each service directory are different; the server 11 may be a server and the host 12 may be a computing device.
An embodiment of the present application provides a method for detecting a working state of a server, where as shown in fig. 2, the method is applied to a proxy host of a network file system NFS, where the NFS is provided with the server and a plurality of hosts, and the proxy host is selected for the plurality of hosts of the NFS based on a preset election principle. The method comprises the following steps:
s201, executing specified operation under the service directory of the NFS server; the specified operation comprises any one of a write operation, a read operation and a modification operation;
specifically, a server of the NFS may provide one service directory, or may provide multiple service directories, and if the server provides multiple service directories, different service directories store different resources; if the proxy host only accesses one output directory of the NFS server, the service directory is mounted in a local directory created by the proxy host to realize the access to the server resources; if the proxy host needs to access a plurality of service directories of the server of the NFS, the service directories of the server are respectively mounted in different local directories created by the proxy host, so that the access to the server resources is realized.
For example, when the server provides a service directory, the IP address of the server is 1.1.1.1, and the service directory output by the server is: 1.1.1.1: the local directory provided by the proxy host is/nfs, and the proxy host can mount the service directory by the following mounting commands: mount-t nfs 1.1.1.1:/nfsdisk/nfs; if the server of the NFS provides multiple service directories, the proxy creates more than two local directories correspondingly, and mounts each service directory in each local directory correspondingly, in the same manner as the above example, and the description is omitted.
The specified operation may be any one of write, read, modify, etc. operations provided by a service directory of a server of the NFS, as the case may be, in actual applications.
For example, in practical applications, the proxy may write a file into a service directory of a server of the NFS at a predetermined interval, and if the file can be successfully written into the service directory, the execution result is successful; if the file cannot be successfully written into the service directory, the execution result is an operation failure. The process of the proxy host performing the modify operation or the read operation is the same as the write operation, and is not described one by one. After the execution result is that the operation is successful, the proxy host can delete the file, so that the memory of the NFS server is prevented from being occupied; the file can be a file with any format and any name, for example, the file can be a file named by writing time; the predetermined time period may be 5 seconds, 1 minute, 5 minutes, etc.
S202, determining the working state of the NFS server according to the execution result after the designated operation is executed;
specifically, the execution result includes operation success and operation failure; the working state of the NFS service end comprises a normal state and an abnormal normal state; when the execution result is that the operation is successful, the working state of the NFS server is a normal state; and when the execution result is operation failure, the working state of the service end of the NFS is an abnormal state.
S203, setting the operation authority of the created local directory based on the determined working state of the NFS server; wherein the operation authority is used for controlling the operation of other hosts except the proxy host on the local directory.
Specifically, the proxy host may create a local directory according to a set creation principle, for example, a name of a service directory corresponding to a service end of the NFS is created to prevent the created local directory from being duplicated with existing directories in the proxy host, where if the service end of the NFS outputs a plurality of service directories, the proxy host creates a corresponding local directory corresponding to each service directory; the operation authority of the local directory may be implemented by setting whether the NFS service function of the local directory is available, the NFS service may provide access to a host other than the proxy host, and the NFS service function of setting the local directory is described in detail in the prior art, and will not be described herein too much.
In practical application, the local directory of the proxy host can be mounted in the local directories of other hosts, so that the other hosts can access the local directory of the proxy host. For example, if the proxy provides a local directory, the local directory of the proxy is: 1.1.0.1: the local/nfaway server, the local directory created by other host at the local end is/nfaway, and through the mount command: mount-t nfs 1.1.0.1: the/local/nfser/nftest will proxy host's local directory 1.1.0.1: mounting the/local/nfaway server into a local directory/nfaway created by each host; if the proxy provides a plurality of local directories, the local directories of the proxy are respectively: 1.1.0.1: percal/nfser 1, 1.1.0.1: the local/nfaway server2, the local directories created by other hosts at the local end are/nfaway test1 and/nfaway test2 respectively, and through the mount command: mount-t nfs 1.1.0.1: the/local/nfaway server 1/nfaway 1 maps the proxy's local directory 1.1.0.1: the/local/nfaway server1 is mounted into the local directory/nfaway 1 created by each host, with the mount command: mount-t nfs 1.1.0.1: the/local/nfaway server 2/nfaway 2 maps the proxy's local directory 1.1.0.1: the/local/nfaway server2 is mounted into a local directory/nfaway 2 created by each host.
Optionally, when step S203 is executed, the setting an operation authority of the created local directory based on the determined working state of the server of the NFS includes:
when the working state of the NFS server is abnormal, setting the operation authority of the local directory to be forbidden;
and when the working state of the NFS server is a normal state, setting the operation authority of the local directory to be allowed to operate.
In practical application, if the working state of the server of the NFS is a normal state, the service directory of the server is considered to be normally accessible, and at this time, the operation authority of the local directory of the proxy host is set to allow operation, that is, the NFS service function of the local directory of the proxy host is set to allow use, so that the operation result of other hosts after executing the specified operation in the local directory is an operation success, so that the other hosts determine that the working state of the server of the NFS is a normal state; if the working state of the server of the NFS is an abnormal state, it is considered that the service directory of the server cannot be normally accessed, and the server may be abnormal, at this time, the operation authority of the local directory of the proxy host is set to be prohibited, that is, the NFS service function of the local directory of the proxy host is set to be prohibited to be used, so that the operation result of other hosts after performing the specified operation in the local directory is an operation failure, so that the other hosts determine that the working state of the server of the NFS is an abnormal state, and the other hosts are prevented from continuously accessing the service directory of the server of the NFS.
Wherein, the election principle comprises any one of the following principles: network protocol (InternetProtocolIP) address is shortest, host name is shortest, host domain name is shortest, etc., and in practical application, it may be determined according to practical situation.
The method for detecting the working state of the server side provided by the embodiment of the application executes the designated operation in the service directory of the server side of the NFS through the proxy host, so as to realize the detection of the working state of the server side, and further, the proxy host determines the working state of the server side of the NFS through the execution of the designated operation in the local directory of the proxy host by setting the operation authority of the created local directory, so that the response speed of the server side of the NFS is improved, and the detection efficiency of the proxy host is correspondingly improved.
Another embodiment of the present application provides a method for detecting a working state of a server, where as shown in fig. 2, the method is applied to other hosts except a proxy host in a network file system NFS, where the NFS is provided with the server and a plurality of hosts, and the proxy host is selected for the plurality of hosts of the NFS based on a preset election principle, and the method includes the following steps:
s301, executing specified operation under the local directory of the proxy host; the specified operation comprises any one of a write operation, a read operation and a modification operation;
s302, determining the working state of the NFS server according to the execution result after the designated operation is executed.
Specifically, the designated operation is any one of write, read, modify, and the like that can be provided for the local directory of the proxy, as the case may be, in actual application
In practical application, other hosts except the proxy host can create a local directory corresponding to a service directory provided by a server, if the server provides one service directory, one local directory is created, and if the server provides a plurality of service directories, a plurality of local directories are correspondingly created; when the local directory is created, the local directory can be created according to a set creation principle, for example, the local directory of the corresponding proxy host is created to prevent the created local directory from being repeated with the existing directory in the host; when a server side of the NFS provides a plurality of service directories, a proxy host correspondingly creates a local directory corresponding to each service directory respectively, and other hosts correspondingly create corresponding local directories in the host corresponding to each local directory of the proxy host; and the other proxy hosts mount the local directory of the proxy host in the created local directory, so that the local directory of the proxy host can be accessed by other hosts except the proxy host.
For example, if the proxy provides a local directory, the local directory of the proxy is: 1.1.0.1: the local/nfaway server, the local directory created locally by other hosts is/nfaway, and through the mount command: mount-t nfs 1.1.0.1: the/local/nfser/nftest will proxy host's local directory 1.1.0.1: mounting the/local/nfaway server into a local directory/nfaway created by each host; if the proxy provides a plurality of local directories, the local directories of the proxy are respectively: 1.1.0.1: percal/nfser 1, 1.1.0.1: the local/nfaway server2, the local directories created by other hosts in each host are/nfaway test1,/nfaway test2, respectively, and through mount commands: mount-t nfs 1.1.0.1: the/local/nfaway server 1/nfaway 1 maps the proxy's local directory 1.1.0.1: the/local/nfaway server1 is mounted into the local directory/nfaway 1 created by each host, with the mount command: mount-t nfs 1.1.0.1: the/local/nfaway server 2/nfaway 2 maps the proxy's local directory 1.1.0.1: the/local/nfaway server2 is mounted into a local directory/nfaway 2 created by each host.
For each host except the proxy host, the host can write files into the local directory of the proxy host at intervals of a preset time, and if the files can be successfully written into the local directory of the proxy host, the execution result is successful; if the file cannot be successfully written into the local directory of the proxy, the execution result is operation failure. The host performs the modification operation or the read operation in the same way as the write operation, and the description thereof is omitted. After the host determines that the execution result is successful, the file can be deleted, so that the storage space in the proxy host is prevented from being occupied; the file can be a file with any format and any name, such as a file named by the write time; the predetermined time period may be 5 seconds, 1 minute, 5 minutes, etc.
Optionally, when step S302 is executed, the determining, according to the execution result after the specified operation is executed, the working state of the NFS server includes:
if the execution result is successful, determining that the working state of the NFS server is a normal state;
if the execution result is operation failure, detecting the network connection state between the home terminal and the proxy host; and after the network connection state between the local terminal and the proxy host is determined to be normal, determining that the working state of the service terminal of the NFS is an abnormal state.
Specifically, the network connection state between the home terminal and the proxy may be detected through an Internet Packet explorer (Packet Internet Groper, PING), or may be detected through a tcping tool, which is not limited in this application.
In practical application, after determining that the execution result is successful, other hosts except the proxy host consider that the home terminal can normally access the local directory of the proxy host, and further determine that the working state of the service terminal of the NFS is a normal state; if the execution result is operation failure, which may be caused by an abnormal service end of the NFS, or an abnormal proxy host, at this time, it may be detected through a ping command whether the network connection between the home end and the proxy host is normal, and if the network connection between the home end and the proxy host is normal, it indicates that the proxy host is not abnormal, and it is determined that the working state of the service end of the NFS is an abnormal state, that is, the service end of the NFS is abnormal.
Optionally, after detecting the network connection state between the home terminal and the proxy, the method further includes:
after determining that the network connection state between the home terminal and the proxy host is abnormal, detecting the network connection state between the home terminal and other hosts except the proxy host;
and if the network connection state between the local terminal and other hosts except the proxy host is normal, determining that the working state of the proxy host is an abnormal state.
In practical application, if the network between the local terminal and the proxy host is abnormal, the local terminal may be abnormal, or the proxy host may be abnormal, at this time, it may be detected through a ping command whether the network connection state between the local terminal and any other host except the proxy host is normal; if the network connection state between the local terminal and any other host except the proxy host is normal, the local terminal is considered not to be abnormal, and the proxy host is considered to be abnormal, namely, the working state of the proxy host is an abnormal state. Furthermore, a new agent host can be elected from other hosts except the agent host based on a preset election principle so as to ensure that the detection of the working state of the server can be continuously carried out and further improve the detection efficiency.
