1. Operating system status monitoring Log in to the system every day to check how the system is running and whether there are error logs or alarm logs.
2. Troubleshooting of the operating system Analyze the cause of the alarm or error according to the fault log of the operating system, so as to solve the problem and ensure the high availability of the operating system.
3. Server status confirmation
In addition to the operating system running on the server, some applications or databases must be installed on the server. The operation and maintenance engineer needs to check whether the status of the applications or databases running on the Linux system is normal every day.
4. Backup
The housekeeping skills of operation and maintenance engineers, database backup and recovery, generally speaking, as long as a backup strategy is formulated for the database, it will back up by itself. You only need to monitor whether the backup task is executed.
5. The requirement for server tuning
is relatively high. As the use time of Linux increases, the state will decline. Operation and maintenance engineers can perform performance tuning on the operating system and database to ensure that the system is in an optimal state. .
Generally speaking, the work of operation and maintenance engineers is mainly based on monitoring, and they will only deal with problems when they occur, which is usually very easy. I am responsible for the operation and maintenance of six servers in three information systems, which is very easy.
