本文主要介绍了在CentOS 7.2环境中通过Yum编译安装MySQL 5.6的详细步骤。首先，作者强调了使用Yum包管理器进行安装的优势，因为Yum是CentOS官方推荐的软件包管理工具，方便、高效且易于管理。 1. 配置CentOS Software Collections (SCL) Repository：在开始安装MySQL 5.6之前，文章指导用户如何添加CentOS SCL仓库，这是为了确保能够获取到支持MySQL 5.6的特定版本。用户需要运行一系列命令来安装`centos-release-scl`和`centos-release-scl-rh`，并在`/etc/yum.repos.d`目录下的相关配置文件中设置优先级，确保SCL仓库被启用但不会自动加载（通过将`enabled=1`改为`enabled=0`）。 2. 安装MySQL 5.6：使用`yum`命令，用户需要指定`centos-sclo-rh`仓库来安装`rh-mysql56-mysql-server`，这会下载并安装MySQL 5.6服务器组件。`--enablerepo`选项用于指定要使用的仓库，`yinstall`命令则实际执行安装操作。 3. 加载MySQL 5.6环境：安装完成后，为了激活MySQL 5.6环境，文章建议使用`scl`工具与`rh-mysql56`关联。通过输入`scl enable rh-mysql56 bash`，系统会临时切换到MySQL 5.6的运行环境。 4. 验证安装和环境设置：用户通过运行`mysql -V`命令验证安装的MySQL版本，确认是否为5.6.26版本，并查看`which mysql`命令输出，确认`mysql`命令的路径，即 `/opt/rh/rh-mysql56/root/usr/bin/mysql`。这篇文章提供了在CentOS 7.2系统上通过Yum编译安装MySQL 5.6的完整指南，包括设置SCL仓库、安装数据库服务器以及创建和激活MySQL 5.6环境的过程，这对于那些希望在该系统上使用特定版本MySQL的用户来说是一份实用的参考材料。

配置配置CentOS SCLo源源

[3] 添加 CentOS SCLo Software collections Repository.

[root@linuxprobe~]# yum -y install centos-release-scl-rh centos-release-scl

# set [priority=10]

[root@linuxprobe~]# sed -i -e "s/\]$/\]priority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo

[root@linuxprobe~]# sed -i -e "s/\]$/\]priority=10/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo

# for another way, change to [enabled=0] and use it only when needed

[root@linuxprobe~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl.repo

[root@dlp ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo

yum安装安装MySQL

# 安装mysql

[root@linuxprobe~]# yum --enablerepo=centos-sclo-rh -y install rh-mysql56-mysql-server

# 加载环境变量

[root@linuxprobe ~]# scl enable rh-mysql56 bash

[root@linuxprobe ~]# mysql -V

mysql Ver 14.14 Distrib 5.6.26, for Linux (x86_64) using EditLine wrapper

[root@linuxprobe ~]# which mysql

/opt/rh/rh-mysql56/root/usr/bin/mysql

# 设置mysql开机自启动

root@linuxprobe ~]# vi /etc/profile.d/rh-mysql56.sh

#!/bin/bash

source /opt/rh/rh-mysql56/enable

export X_SCLS="`scl enable rh-mysql56 'echo $X_SCLS'`"

[4] Enable MySQL 5.6 and Configure initial settings.

[root@linuxprobe ~]# vi /etc/opt/rh/rh-mysql56/my.cnf.d/mysql-server.cnf

# add follows within [mysqld] section

[mysqld]

character-set-server=utf8

[root@linuxprobe ~]# systemctl start rh-mysql56-mysqld

[root@linuxprobe ~]# systemctl enable rh-mysql56-mysqld

[root@linuxprobe ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL

SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current

password for the root user. If you've just installed MySQL, and

you haven't set the root password yet, the password will be blank,

so you should just press enter here.

Enter current password for root (enter for none):

OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL

root user without the proper authorisation.

# set root password

Set root password? [Y/n] y

New password:

Re-enter new password:

Password updated successfully!

Reloading privilege tables..

... Success!

By default, a MySQL installation has an anonymous user, allowing anyone

to log into MySQL without having to have a user account created for

them. This is intended only for testing, and to make the installation

go a bit smoother. You should remove them before moving into a

production environment.

# remove anonymous users

Remove anonymous users? [Y/n] y

... Success!

Normally, root should only be allowed to connect from 'localhost'. This

ensures that someone cannot guess at the root password from the network.

# disallow root login remotely

Disallow root login remotely? [Y/n] y

... Success!

By default, MySQL comes with a database named 'test' that anyone can

access. This is also intended only for testing, and should be removed

before moving into a production environment.

# remove test database
