# 安装MySQL的yum源，下面是RHEL6系列的下载地址rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm# 安装yum-config-manageryum install yum-utils -y# 禁用MySQL5.6的源yum-config-manager --disable mysql56-community# 启用MySQL5.7的源yum-config-manager --enable mysql57-community-dmr# 用下面的命令查看是否配置正确yum repolist enabled | grep mysql |
检查是否有mysql57-community-dmr这个源，如上图所示。

# 安装MySQL5.7yum install mysql-community-server |
如果安装失败
给CentOS添加rpm源，并且选择较新的源
1）下载rpm包
[root@iZ2366ycl7sZ software]# wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm --no-check-certificate --2019-03-29 14:45:46-- http://dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm Resolving dev.mysql.com... 137.254.60.11 Connecting to dev.mysql.com|137.254.60.11|:80... connected.

补充：
如果上面的wget文件下载不了（有同学反馈无法下载），可直接下载 ；
git地址 http://t.istester.com:3000/istester/idoxu.git
2）安装本地mysql源
[root@iZ2366ycl7sZ software]# yum localinstall mysql-community-release-el6-5.noarch.rpm Loaded plugins: security Setting up Local Package Process Examining mysql-community-release-el6-5.noarch.rpm: mysql-community-release-el6-5.noarch Marking mysql-community-release-el6-5.noarch.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package mysql-community-release.noarch 0:el6-5 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================== Package Arch Version Repository Size ======================================================================================================================================== Installing: mysql-community-release noarch el6-5 /mysql-community-release-el6-5.noarch 4.3 k Transaction Summary ======================================================================================================================================== Install 1 Package(s) Total size: 4.3 k Installed size: 4.3 k Is this ok [y/N]: y Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : mysql-community-release-el6-5.noarch 1/1 Verifying : mysql-community-release-el6-5.noarch 1/1 Installed: mysql-community-release.noarch 0:el6-5 Complete!
3）验证是否安装成功
[root@iZ2366ycl7sZ software]# yum repolist all | grep mysql mysql-connectors-community MySQL Connectors Community enabled: 83 mysql-connectors-community-source MySQL Connectors Community - S disabled mysql-tools-community MySQL Tools Community enabled: 74 mysql-tools-community-source MySQL Tools Community - Source disabled mysql55-community MySQL 5.5 Community Server disabled mysql55-community-source MySQL 5.5 Community Server - S disabled mysql56-community MySQL 5.6 Community Server enabled: 493 mysql56-community-source MySQL 5.6 Community Server - S disabled mysql57-community-dmr MySQL 5.7 Community Server Dev disabled mysql57-community-dmr-source MySQL 5.7 Community Server Dev disabled
修改默认版本为5.7
执行：
yum-config-manager --disable mysql56-community
yum-config-manager --enable mysql57-community-dmr
如上操作，是把5.6禁用，把5.7启用
此法，会有异常情况：
如果执行命令出现如下错误：
-bash: yum-config-manager: command not found
可用执行如下命令解决，然后继续上面的操作命令：
yum -y install yum-utils
三、启动MySQL

# 禁用selinuxsetenforce 0sed -i '/^SELINUX=/c\SELINUX=disabled' /etc/selinux/config # 启动mysqld，启动之前先修改/etc/my.cnf配置文件，本文用默认的配置。service mysqld start |
四、连接MySQL并修改密码
