How to install MySQL in Linux

An earlier version of mysql server has been installed on the Linux server in use. When the rpm package is used for installation, a version conflict is prompted and the installation cannot proceed.

The solution is as follows:

1. First, find all the mysql instances installed in the system.
# Rpm-qa | grap-I after mysql runs this command, all lists are displayed.
Mysql-4.1.20-1.RHEL4.1
Mysqlclient10-3.23.58-4.RHEL4.1

2. Force Delete the list one by one:
# Rpm-ev -- nodeps mysql-4.1.20-1.RHEL4.1.
# Rpm-ev -- nodeps mysqlclient10-3.23.58-4.RHEL4.1.

Manually delete the files of earlier versions:
# Rpm-f/etc/my. cnf
# Rpm-rf/usr/var/lib/mysql
Now you can perform a new installation of mysql, the required software package:

3. software to be installed
MySQL-client-5.0.22-0.i386.rpm MySQL client software
MySQL-server-5.0.22-0.i386.rpm MySQL Server Software
Rpm-ivh MySQL-client-5.0.22-0.i386.rpm
