For MySQL installed under Linux via RPM, we can remove these rpm packages and delete the items directory to achieve the uninstall purpose. This article demonstrates uninstalling the MySQL 5.5.37 under SuSE Linux 10. See below for details.
1. Environment
Copy Code code as follows:
#OS环境
szdb:~ # Cat/etc/issue
Welcome to SUSE Linux Enterprise Server SP3 (x86_64)-Kernel \ R (\l).
#查看已安装的安装包
szdb:~ # Rpm-qa | Grep-i MySQL
Mysql-devel-5.5.37-1.sles10
Mysql-server-5.5.37-1.sles10
Mysql-shared-compat-5.5.37-1.sles10
Mysql-client-5.5.37-1.sles10
Mysql-shared-5.5.37-1.sles10
Mysql-test-5.5.37-1.sles10
Mysql-embedded-5.5.37-1.sles10
2. Stop MySQL Service
Copy Code code as follows:
szdb:~ #/etc/init.d/mysql Stop
Shutting down MySQL. Done
3. Uninstall MySQL with rpm
Copy Code code as follows:
szdb:~ # rpm-e--nodeps mysql-server-5.5.37-1.sles10
Insserv:script Postgresqlmemory:service PostgreSQL already provided!
Insserv:script Postgresql:service PostgreSQL already provided!
MySQL 0:off 1:off 2:off 3:off 4:off 5:off 6:off
#使用下面的方式移除所有mysql RPM Package
szdb:~ # rpm-e--nodeps mysql-client-5.5.37-1.sles10
szdb:~ # rpm-e--nodeps mysql-devel-5.5.37-1.sles10
szdb:~ # rpm-e--nodeps mysql-shared-compat-5.5.37-1.sles10
szdb:~ # rpm-e--nodeps mysql-shared-5.5.37-1.sles10
szdb:~ # rpm-e--nodeps mysql-test-5.5.37-1.sles10
szdb:~ # rpm-e--nodeps mysql-embedded-5.5.37-1.sles10
4, the removal of the relevant MySQL directory and files
Copy Code code as follows:
szdb:~ # Find/-name MySQL
/etc/apparmor.d/abstractions/mysql
/var/lib/mysql
/var/lib/mysql/mysql
/usr/lib64/mysql
/usr/local/quickfix_old/src/sql/mysql
szdb:~ # Rm-rf/etc/apparmor.d/abstractions/mysql
szdb:~ # Rm-rf/var/lib/mysql
szdb:~ # Rm-rf/var/lib/mysql/mysql
szdb:~ # Rm-rf/usr/lib64/mysql
szdb:~ # Rm-rf/usr/local/quickfix_old/src/sql/mysql
szdb:~ # ls/etc/my*
/bin/ls:/etc/my*: No such file or directory
Note, if there are my.cnf in the/etc directory, do the corresponding removal
Consider whether to remove MySQL users from Linux as needed
Copy Code code as follows:
szdb:~ # CAT/ETC/PASSWD | grep MySQL
Mysql:x:104:106:mysql Server:/var/lib/mysql:/bin/bash
5. Verify the result
Copy Code code as follows:
szdb:~ # Rpm-qa | Grep-i MySQL
szdb:~ # chkconfig--list |grep MySQL
