安裝環境：CentOS7 64位 MINI版，安裝MySQL5.7
1、配置YUM源
在MySQL官網中下載YUM源rpm安裝包：http://dev.mysql.com/downloads/repo/yum/
# 下載mysql源安裝包
shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
# 安裝mysql源
shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm檢查mysql源是否安裝成功
shell> yum repolist enabled | grep "mysql.*-community.*" 
看到上圖所示表示安裝成功。
可以修改vim /etc/yum.repos.d/mysql-community.repo源，改變默認安裝的mysql版本。比如要安裝5.6版本，將5.7源的enabled=1改成enabled=0。然後再將5.6源的enabled=0改成enabled=1即可。改完之後的效果如下所示： 
2、安裝MySQL
shell> yum install mysql-community-server3、啟動MySQL服務
shell> systemctl start mysqld查看MySQL的啟動狀態
shell> systemctl status mysqld
● mysqld.service - MySQL Server

shell> systemctl enable mysqld
shell> systemctl daemon-reload5、修改root本地登錄密碼
mysql安裝完成之後，在/var/log/mysqld.log文件中給root生成了一個默認密碼。通過下面的方式找到root默認密碼，然後登錄mysql進行修改：
shell> grep ‘temporary password‘ /var/log/mysqld.log
shell> mysql -uroot -p //登錄mysqlcentOS 7 安裝mysql
