I believe that the packages engaged in linux Server O M are the same as those of me. They are dealing with various system logs and service logs every day. These logs record the status of the system or service that occurs every day. By observing logs, We can promptly resolve many system and service faults.
Today, rsyslog is used to centrally collect system logs and user operation records, and to process collected logs. For example, server exception mo

Write shell script execution to Rsyslog Log Server
In the O M work, it is inevitable to write some scripts for scheduled tasks (cron) to regularly execute some daily work to automate the O M work. For example, backing up data in my daily work is an important task. You need to regularly back up the data to the backup server and some other backup media. Most of the backup work is written to the script, and the/etc/crontab is edited to regularly comple
