Uninstall MySQL



[[email protected] ~]# rpm-qa|grep MySQL

mod_auth_mysql-2.6.1-2.2

php-mysql-4.3.9-3.15

mysql-devel-4.1.20-1.rhel4.1

mysql-4.1.20-1.rhel4.1

mysqlclient10-3.23.58-4.rhel4.1

libdbi-dbd-mysql-0.6.5-10.rhel4.1


Description: Rpm–qa | The grep mysql command is to list all MySQL related packages, the example above is the LinuxAS4 default install MySQL RPM package list,

If it's a list of other Linux versions, it might not be the same, but don't worry, no matter what, uninstall starts with the bottom one, until the first one is uninstalled.

Description: Rpm–e is the command to unload the RPM package, followed by the package name, the final version number is not to fight, such as our next uninstall mysqlclient10-3.23.58-4.rhel4.1 package

Here's how:

Rpm–e mysqlclient


Uninstalling Apache

[Email protected] ~]# Rpm-qa|grep httpd

Httpd-manual-2.0.52-25.ent

System-config-httpd-1.3.1-1

Httpd-2.0.52-25.ent

Httpd-suexec-2.0.52-25.ent


Description: The method is the same as uninstalling MySQL, needless to say.


Uninstalling PHP

[[email protected] ~]# rpm-qa|grep PHP

php-odbc-4.3.9-3.15

php-4.3.9-3.15

php-mysql-4.3.9-3.15

php-pear-4.3.9-3.15

php-ldap-4.3.9-3.15

php-pgsql-4.3.9-3.15


Description: The same method as uninstalling MySQL


Note: If the uninstallation is not removed, the system will generally prompt the package dependencies, and list the name of the dependent package, first uninstall the prompt depends on the package is ready.


If there is really a unloading package, you can add-nodeps this parameter to unload, for example, we uninstall php-4.3.9-3.15, it is not removed.


Just use:

[Email protected] ~]# rpm-e php-4.3.9-3.15--nodeps
