[ example 1 ]
The embodiment provides a method for automatically controlling a host to restart, which includes:
s101: and acquiring a restart template, wherein an automatic restart process is defined in the restart template.
The restart template of the embodiment is used for restarting a UNIX-like operating system, such as an AIX operating system, an HPUX operating system and a LINIX operating system. According to different host deployment modes, the restart template can be divided into a database operation template and a non-database operation template, which respectively define an automatic restart process of a database host and a restart process of non-database hosts such as a Web host, an AP host and the like.
Before restarting, the restart template can be stored in advance, and a restart template list is provided for a user to select. After the user selection, a user-selected restart template may be obtained.
S102: and collecting system related information of the target host.
Before acquisition, a list of hosts may be obtained and provided for the user to select a target host that needs to be restarted. The target host selected by the user may be one or more. After the target host is determined, the acquisition script under the restart template selected by the user can be issued to the target host to acquire system related information of the target host.
S103: and judging whether the target host is suitable for the restarting template or not according to the system related information of the host.
The method comprises the steps that for a non-database restarting template, collected system related information of a target host comprises an IP address, an operating system type, a deployment type and the like of the host, whether the target host is suitable for the current target restarting template can be judged according to the operating system type and the deployment type of the host, and if the target host is not suitable for the current target restarting template, a user can be reminded to reselect. And aiming at the condition that a plurality of target hosts are available, reminding a user of the target host which is not suitable for the current target restarting template so as to re-determine the selected restarting host.
For the database restart template, the collected system-related information of the target host may include, in addition to the IP address, the operating system type, the deployment type, and the like of the host, the system-related information of the database instance deployed on the target host, for example, the database activity instance name, the activity instance number, the current database name, the database version, the current instance name, whether or not RAC is related information, and in addition to judging whether the target host is suitable for the current restart template according to the IP address, the operating system type, and the deployment type, whether or not the target host is suitable for the current restart template may be further judged according to the related information of the database instance.
S104: and if the target host is suitable for the restarting template, automatically restarting the target host according to the automatic restarting flow of the restarting template. The automatic restart procedure will be described in detail below.
According to the embodiment, the target host can be automatically restarted according to the automatic restarting process of the restarting module applicable to the target host.
[ example 2 ]
The embodiment provides a method for automatically controlling a non-database host (such as an AP host and a WEB host) to restart. As shown in fig. 2, the method for automatically controlling the non-database host to restart includes:
s201: and acquiring a non-database restart template, wherein an automatic restart process of a non-database host is defined in the target restart template.
S202: collecting system related information of a target host;
s203: and judging whether the target host is suitable for the non-database restarting template or not according to the system related information.
S204: and if the target host is suitable for the non-database restarting template, automatically restarting the target host according to an automatic restarting flow of the non-database restarting template.
Specifically, in step S104, if the target host is suitable for the non-database restart template, the associated script under the non-database restart template may be issued to the target host, where the associated script includes, but is not limited to, a user process stop script, a status information acquisition script, a restart script, an NTP (Network Time Protocol) status check script, an information comparison script, a process start script, and the like.
After the issuing, the user process stop script may be started to stop the user process on the target host, and then it may be checked whether all the user processes on the target host have stopped, and if all the user processes have stopped, the state information obtaining script may be started to obtain the state information on the target host, where the state information may include some information of a system layer of the host, for example, state, information, and the like of hardware devices such as a system process, system parameters, a network card, and the like. After the state information of the target host is acquired, the acquired state information may be saved in a designated directory to be compared with the restarted state information. After saving the state information, a restart script may then be launched to restart the target host.
After the target host is restarted, the NTP status check script may be started to check the status of the NTP. The NTP state is a clock synchronization state of the current target host and the clock synchronization server, and when the NTP state is recovered, that is, after the clock of the current target host and the clock of the clock synchronization server are synchronized, the state information acquisition script may be restarted to acquire the state information of the restarted target host. The state information of the target host after the reboot can then be compared with the state information saved before the reboot. If the comparison is consistent, the process starting script can be started to start the user process before restarting. If the state information before and after restarting is inconsistent, an inconsistent item can be output, for example, the inconsistent item is listed on a display, and the subsequent user process starting operation is performed after the operation and maintenance personnel process the inconsistent item.
In this embodiment, each target host can be automatically restarted through one cloud device without logging in each host system to perform manual operation, so that the restarting efficiency is improved, and the restarting can be performed only by one operation and maintenance worker. Moreover, in the embodiment, each check is realized through the script during restarting, and compared with manual check, misoperation and omission can be avoided, and the reliability of restarting is improved.
In some implementations of this embodiment, after the NTP status is restored, it may be checked whether a CTM (CONTROL-M, a job scheduling platform) job schedule is configured on the target host, and if so, the CTM job schedule may be invoked.
Typically, a monitoring process (e.g., a control process) on the target host is automatically launched upon reboot, with some exceptions. In some implementation manners of this embodiment, after the user process before the start is adjusted, it may also be checked whether the monitoring process on the target host is already started, and when the monitoring process is not started, the monitoring process is started.
[ example 3 ]
The embodiment provides a method for automatically controlling a database host to restart. As shown in fig. 3, the method for automatically restarting the database host includes:
s301: and acquiring a database restart template, wherein an automatic restart process of the database host is defined in the target restart template.
S302: collecting system related information of a target host;
s303: and judging whether the target host is suitable for the database restarting template or not according to the system related information.
S304: and if the target host is suitable for the database restarting template, automatically restarting the target host according to an automatic restarting flow of the database restarting template.
Specifically, in step S304, if the target host is suitable for the database restart template, a related script under the database restart template may be issued to the target host, where the related script includes, but is not limited to, a user process stop script, a state information acquisition script, a restart script, an NTP state check script, an information comparison script, a process call script, and the like.
Further, the user process stop script may be initiated to stop the user process on the target host. For the database host, the user process on the database host is a process of the database, and at this time, stopping the user process on the target host specifically may include: the health state of the database instances on the target host is detected, for example, the active/standby health states of the database may be checked, and when the active/standby health states are normal, the database instances on the target host may be sequentially stopped. When all database instances are stopped, the health status of a CRS (Cluster Ready Service of Oracle) Cluster may be checked, and when the health status of the CRS Cluster is normal, the CRS Cluster resources may be stopped.
After stopping, it can be checked whether all user processes on the target host have stopped. If the user processes are all stopped, an instruction may be issued to start a state information acquisition script to acquire state information on the target host, where the state information may include some information of a system layer of the host, for example, state, information, and the like of hardware devices such as a system process, system parameters, a network card, and the like. After the state information of the target host is acquired, the acquired state information may be saved in a designated directory to be compared with the restarted state information. After saving the state information, an instruction may be issued to start a restart script to restart the target host.
After the target host is restarted, the NTP status check script may be started to check the status of the NTP. The NTP state is a clock synchronization state of the current target host and the clock synchronization server, and when the NTP state is recovered, that is, after the clock of the current target host and the clock of the clock synchronization server are synchronized, the state information acquisition script may be restarted to acquire the state information of the restarted target host. The state information of the target host after the reboot can then be compared with the state information saved before the reboot. If the comparison is consistent, the process starting script can be started to start the user process before restarting. For the database host, the adjusting of the user process before restarting may specifically include: invoking CRS cluster resources, invoking database instances, etc.
If the state information before and after restarting is inconsistent, inconsistent items can be output, for example, the inconsistent items are listed on a screen, and the subsequent process starting operation is performed after the operation and maintenance personnel process the inconsistent items.
In some implementations of this embodiment, after the NTP status is restored, it may be checked whether a CTM job schedule is configured on the target host, and if so, the CTM job schedule may be invoked.
Typically, the monitoring process on the target host is automatically started after a reboot, with some exceptions. In some implementation manners of this embodiment, after the user process before the start is adjusted, it may also be checked whether the monitoring process on the target host is already started, and when the monitoring process is not started, the monitoring process is started.
