How to resolve the issue of mysql killed process not ending?

If the MySQL process is not automatically restarted after being killed, you can try the following methods to resolve this issue:

1. Check the MySQL log: Review the error log file for MySQL, usually located in /var/log/mysql/error.log or /var/log/mysqld.log. Look for any errors or warnings in the log, as they may provide clues about the issue.
2. Restart the MySQL service: Use the appropriate command to restart the MySQL service, such as systemctl restart mysql or service mysql restart. This will attempt to restart the MySQL process.
3. Check system resources: MySQL may not have enough system resources to start. You can use the top or htop command to check the CPU and memory usage of the system. If this is the reason for the problem, you may need to increase system resources or optimize MySQL configuration.
4. Check the MySQL configuration file: Review the MySQL configuration file (usually located at /etc/mysql/my.cnf or /etc/my.cnf) to ensure there are no incorrect configuration options. You can try restoring to the default configuration file and gradually re-adding modifications one by one to pinpoint the issue.
5. Kill remaining processes: If there are still lingering processes after killing the MySQL process, you can manually kill these processes using the kill command. First, use the ps aux | grep mysql command to find the PID (Process ID) of the MySQL process, then use the kill PID command to kill the process. If the process still cannot be terminated, you can try using the kill -9 PID command for a forceful kill.
6. Reinstalling MySQL: If the above methods do not work, you can try reinstalling MySQL. Make sure to back up all important data before uninstalling MySQL.
