3 下載mysql源安裝包 shell> wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
4 安裝mysql源 shell> yum localinstall mysql57-community-release-el7-8.noarch.rpm
5 檢查mysql源是否安裝成功

6 安裝MySQL
shell> yum install mysql-community-server
7 啟動MySQL服務
shell> systemctl start mysqld
8 重新啟動
shell> systemctl restart mysqld
9 查看MySQL的啟動狀態
shell> systemctl status mysqld
10 開機啟動
shell> systemctl enable mysqld shell> systemctl daemon-reload
11 修改root默認密碼
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
Enter password: 輸入默認密碼 mysql> ALTER USER [email protected]
/* */ IDENTIFIED BY ‘MyNewPass4!‘;
或者
mysql> set password for [email protected]=password(‘MyNewPass4!‘);
12 添加遠程登錄用戶
默認只允許root帳戶在本地登錄，如果要在其它機器上連接mysql，必須修改root允許遠程連接，或者添加一個允許遠程連接的帳戶，為了安全起見，我添加一個新的帳戶：
mysql> grant all privileges on *.* to [email protected]%‘ identified by ‘mypassword‘ with grant option;
mysql> flush privileges;
grant all privileges on *.* to 創建的用戶名 @"%" identified by "密碼";
flush privileges; * 刷新剛才的內容*
格式：grant 權限 on 數據庫教程名.表名 to [email protected]
