Mysql 使用yum 切换源

[root@juny-18 ~]# cat /etc/redhat-release

CentOS Linux release 7.4.1708 (Core)

网络yum源已经配好

检查系统是否自带有MySQL

[root@juny-18 ~]# yum list installed | grep mysql

如果有就用下面这命令来删除

Yum remove -y (安装包名)

第一步 下载yum库

[root@juny-18 ~]# wget //dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

--2017-11-01 23:33:57-- //dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

正在解析主机 dev.mysql.com (dev.mysql.com)... 137.254.60.11

正在连接 dev.mysql.com (dev.mysql.com)|137.254.60.11|:80... 已连接。

安装MySQL的yum源

[root@juny-18 ~]# yum localinstall mysql57-community-release-el7-8.noarch.rpm

已加载插件：fastestmirror, langpacks

正在检查 mysql57-community-release-el7-8.noarch.rpm: mysql57-community-release-el7-8.noarch

mysql57-community-release-el7-8.noarch.rpm 将被安装

正在解决依赖关系

There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).

检查MySQL源的安装是否成功

[root@juny-18 ~]# yum repolist enabled | grep "mysql.*-community.*"

mysql-connectors-community/x86_64 MySQL Connectors Community 42

mysql-tools-community/x86_64 MySQL Tools Community 51

mysql57-community/x86_64 MySQL 5.7 Community Server 227
