Linux Learning CentOS (iii): Installation and configuration of MySQL database

First, uninstall the original MySQL system

Switch to the root user operation:

[email protected] ~]$ su

See if the operating system has a MySQL database installed:

[Email protected] carsonzhu]# Rpm-qa | grep MySQL

Mysql-libs-5.1.71-1.el6.x86_64

Then I try to delete MySQL in the following way (I'm having a problem):

[Email protected] carsonzhu]# rpm-e mysql-libs-5.1.71-1.el6.x86_64error:failed dependencies:libmysqlclient.so.16 () (64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64libmysqlclient.so.16 (libmysqlclient_16) (64bit) is needed by (installed) Postfix-2:2.6.6-2.2.el6_1.x86_64mysql-libs are needed by (installed) Postfix-2:2.6.6-2.2.el6_1. X86_64[[email protected] carsonzhu]# rpm-e mysql-libs-5.1.71-1.el6.x86_64.rpm--nodepserror:package MYSQL-LIBS-5.1.71-1.EL6.X86_64.RPM is not installed

Said to unload when there is a dependency on the package, you need to unload the postfix-2:2.6.6-2.2.el6_1.x86_64, RPM-E postfix-2:2.6.6-2.2.el6_1.x86_64 is not! Then I search for solutions (CentOS 6.3 64-bit under the thorough uninstall mysql5.5.25 illustrated tutorial) are:

If there is a CentOS self-mysql-libs-5.1.71-1.el6.x86_64 use the following command to uninstall

[Email protected] carsonzhu]# Rpm-ev--nodeps mysql-libs-5.1.71-1.el6.x86_64
[[email protected] carsonzhu]# rpm-qa|grep-i MySQL//See if MySQL has been uninstalled successfully
I found out there's nothing.
[[email protected] carsonzhu]# Find/-name MySQL//Find the previous old version of MySQL directory
Found no content
(Note: Suppose the results are as follows:
[[email protected] ~]# Find/-name MySQL
#/var/lib/mysql
#/var/lib/mysql/mysql
#/usr/lib64/mysql
Delete the corresponding MySQL directory
# Rm-rf/var/lib/mysql
# Rm-rf/var/lib/mysql
# Rm-rf/usr/lib64/mysql
/ETC/MY.CNF will not be removed after uninstallation, manual removal is required
# RM-RF/ETC/MY.CNF)

View the version of MySQL that is available for download on Yum:
