CentOS 6.7下yum方式怎么安装MySQL 5.6

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

完毕！

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.

[root@test ~]# mysql -u root -p

Enter password:
