本篇文章给大家分享的是有关CentOS 6.7下yum方式怎么安装MySQL 5.6，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。
1、下载yum源
我的测试环境如下：
[root@test ~]# cat /etc/redhat-release
CentOS release 6.7 (Final)
所以下载了centos6系统yum源:
wget http://dev.mysql.com/get/mysql57-community-release-el6-7.noarch.rpm
3、修改yum源配置
vim /etc/yum.repos.d/mysql-community.repo
安装mysql5.6操作
1）、将其他版本enabled=1更改为enabled=0
2）、将5.6版本enabled=0更改为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、开始现在安装包并安装
[root@test ~]# yum install mysql-community-server
已加载插件：fastestmirror, security
设置安装进程

5、启动mysql服务
[root@test ~]# service mysqld start
初始化 MySQL 数据库： 2020-03-30 23:47:20 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
2020-03-30 23:47:20 0 [Note] Ignoring --secure-file-priv value as server is running with --bootstrap.
…
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
[确定]
正在启动 mysqld： [确定]
6、查看状态和版本
[root@test ~]# chkconfig --list | grep mysqld
mysqld 0:关闭 1:关闭 2:关闭 3:启用 4:启用 5:启用 6:关闭
[root@test ~]# mysqladmin --version
mysqladmin Ver 8.42 Distrib 5.6.47, for Linux on x86_64
[root@test ~]# mysqladmin -u root password "mysql123"
Warning: Using a password on the command line interface can be insecure.
