Uninstall built-in mysql commands under Centos

1. First find the Mysql-related rpm

rpm -qa | grep mysql[root@hexuweb102 ~]$ rpm -qa | grep mysql#mysql-connector-odbc-3.51.12-2.2#mysql-5.0.45-7.el5#mysql-server-5.0.45-7.el5#libdbi-dbd-mysql-0.8.1a-1.2.2

2. Start uninstall

[root@hexuweb102 ~]$ rpm -e libdbi-dbd-mysql-0.8.1a-1.2.2[root@hexuweb102 ~]$ rpm -e mysql-server-5.0.45-7.el5[root@hexuweb102 ~]$ rpm -e mysql-5.0.45-7.el5#error: Failed dependencies:#libmysqlclient.so.15 is needed by (installed) perl-DBD-MySQL-3.0007-1.fc6.i386#libmysqlclient.so.15 is needed by (installed) dovecot-1.0.7-2.el5.i386#libmysqlclient.so.15 is needed by (installed) mysql-connector-odbc-3.51.12-2.2.i386#libmysqlclient.so.15(libmysqlclient_15) is needed by (installed) perl-DBD-MySQL-3.0007-1.fc6.i386#libmysqlclient.so.15(libmysqlclient_15) is needed by (installed) dovecot-1.0.7-2.el5.i386#libmysqlclient.so.15(libmysqlclient_15) is needed by (installed) mysql-connector-odbc-3.51.12-2.2.i386#libmysqlclient_r.so.15 is needed by (installed) MySQL-python-1.2.1-1.i386#libmysqlclient_r.so.15 is needed by (installed) mysql-connector-odbc-3.51.12-2.2.i386#libmysqlclient_r.so.15(libmysqlclient_15) is needed by (installed) MySQL-python-1.2.1-1.i386#libmysqlclient_r.so.15(libmysqlclient_15) is needed by (installed) mysql-connector-odbc-3.51.12-2.2.i386#mysql is needed by (installed) MySQL-python-1.2.1-1.i386

Because the following packages depend on the mysql package, you may not be able to use other mysql packages after you delete them.

Solution:

1. Add-nodeps to unmount

rpm -e --nodeps mysql

2. Uninstall the dependency first.

[root@hexuweb102 ~]$ rpm -e perl-DBD-MySQL-3.0007-1.fc6.i386[root@hexuweb102 ~]$ rpm -e dovecot-1.0.7-2.el5.i386............

2. Deleting it with yum will automatically resolve the dependency

[root@hexuweb102 ~]yum remove mysql

We recommend that you use yum to delete or install the software. The dependency between packages is troublesome.
