本機需要連線網際網路(後面例項是以線上安裝為例）

2、 新增下載的yum源(可用命令localinstall/install)，進入資料夾Software，輸入以下命令

[root@localhost Software]# yum install -ymysql57-community-release-el7-9.noarch.rpm

3、 安裝MySQL(檢查啟用可安裝程式元件)

[root@localhost Software]# yum repolist all | grep mysql
[root@localhost Software]# yum install -y  mysql-community-server

[root@localhost Software]# service mysqld start

5、 檢視root臨時密碼

[root@localhost Software]# grep "password"/var/log/mysqld.log

2017-02-05T09:22:20.086699Z 1 [Note] A temporary passwordis generated for root@localhost: 9j6srtfRp>;D

6、 測試連線

5.1、連線MySQL(輸入密碼直接右健貼上，回車健確認)

[root@localhostSoftware]# mysql -u root -p

Enter password: 9j6srtfRp>;D

5.2、測試連線效果

以下提示需要重置密碼才能操作

mysql>show databases
    -> ;
ERROR 1820 (HY000): You must reset your password usingALTER USER statement before executing this statement.
