Linux yum安装MySQL5.7

一、安装配置MySQL的yum源

1 2 3 4 5 6 7 8 9 10

# 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-manager yum 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。

    二、yum安装MySQL5.7

1 2	# 安装MySQL5.7 yum 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

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 ；

2）安装本地mysql源

[root@iZ2366ycl7sZ software]# yum localinstall mysql-community-release-el6-5.noarch.rpm

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

1 2 3 4 5

# 禁用selinux setenforce 0 sed -i '/^SELINUX=/cSELINUX=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
