This article is to share with you about how to install yum under CentOS 6.7. the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

1. Download the yum source

My test environment is as follows:

[root@test ~] # cat / etc/redhat-release

CentOS release 6.7 (Final)

So I downloaded the centos6 system yum source:

Wget http://dev.mysql.com/get/mysql57-community-release-el6-7.noarch.rpm

3. Modify yum source configuration

Vim / etc/yum.repos.d/mysql-community.repo

Install mysql5.6 operation

1), change other versions of enabled=1 to enabled=0

2) change version 5.6 enabled=0 to enabled=1

# Enable to use MySQL 5.6

[mysql56-community]

Name=MySQL 5.6 Community Server

Baseurl= http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/

Enabled=1

Gpgcheck=1

Gpgkey= file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

4. Install the package and install it now.

[root@test ~] # yum install mysql-community-server

...

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER!

To do so, start the server, then issue the following commands:

/ usr/bin/mysqladmin-u root password' new-password'

/ usr/bin/mysqladmin-u root-h test password' new-password'

Alternatively you can run:

/ usr/bin/mysql_secure_installation

Which will also give you the option of removing the test

...

Note: new default config file not created.

Please make sure your config file is current

WARNING: Default config file / etc/my.cnf exists on the system

This file will be read by default by the MySQL server

If you do not want to use this, either remove it, or use the

-- defaults-file argument to mysqld_safe when starting the server
