# rpm -ev mysql-client-5.0.94-0.2.4.1
# rm -rf /var/lib/mysql
# rm -rf /etc/my.cnf
Run the ps -e|grep mysql command to check whether the MySQL process exists.
If the following message is displayed, the MySQL process is still running. 9052 and 9652 are process IDs (PIDs).

 9052 ?        00:00:00 mysqld_safe 
 9652 ?        02:40:31 mysqld     
```
If the MySQL process exists, run the kill -9 PID command to stop the process. For example, kill -9 9052.
Run the following command to check whether the MySQL installation package is deleted.
# which mysql
If the following information is displayed, MySQL has been uninstalled.
