1, 看起來mysql又提供yum安裝了。
yum install mysql-server
先安裝wget
yum -y install wget
2,下載rpm安裝文件
wget http://repo.mysql.com/mysql-community-release-el7.rpm
3,執行rpm安裝
rpm -ivh mysql-community-release-el7.rpm

4,可以看出，server和client都被選擇安裝。選擇y，自動下載安裝。
5,安裝完成后，啟動Mysql。
systemctl start mysqld.service
啟動
1、使用 service 啟動：service mysqld start
2、使用 mysqld 腳本啟動：/etc/inint.d/mysqld start
停止
1、使用 service 啟動：service mysqld stop
2、使用 mysqld 腳本啟動：/etc/inint.d/mysqld stop
重啟
1、使用 service 啟動：service mysqld restart
2、使用 mysqld 腳本啟動：/etc/inint.d/mysqld restart
登錄mysql：mysql -u root -p（開始密碼默認為空，直接回車）
6,設置密碼
use mysql
ALTER USER 'root'@'localhost' IDENTIFIED BY '密碼';
/update user set password=password("123456") where user='root';/
7,開機自啟動
systemctl enable mysqld
systemctl daemon-reload
8,重要更新
新的rpm安裝文件沒有自動yum安裝的腳本了，需要手動執行yum安裝。
即步驟3之后執行yum install mysql-server即可。
9，關於自啟動
步驟7只適用於mysqld沒有自啟動的條件下。
如果默認mysql是自啟動的，可能和rc.local中的自啟動出現亂序之類的問題。
更穩妥的一個解決辦法見：
CentOS 7 程序自啟動的問題
http://www.cnblogs.com/yoyotl/p/6194321.html
打開遠程訪問：
修改host為所有ip可登陸
update user set host='%' where user='root';
修改密碼
Alter user 'root'@'%' identified by '密碼';
授權
grant all privileges on *.* to 'root'@'%' with grant option;
FLUSH PRIVILEGES;

You can turn off this feature to get a quicker startup with -A
