2.2.4. 启动数据库，配置服务自启动

#systemctl start mysqld
#systemctl enable mysqld

 查看数据库是否已经启动，配置服务是否添加自启动成功

#ps -ef|grep mysqld #查看运行进程
#systemctl status mysqld #查看运行状态
#systemctl list-unit-files |grep mysqld #查看是否自启动

2.2.5. 修改MySQL数据库root用户密码
 获取MySQL数据库root用户的临时密码

#cat /data/mysql/logs/error.log | grep 'A temporary password'
[Note] A temporary password is generated for root@localhost: #5+t+xYW+ 其中#5+t+xYW+#mysql -uroot -p
Enter password:
mysql> alter user 'root'@'localhost' identified by '密码';
mysql> flush privileges;

2.2.6. 防火墙开放端口
 根据实际要求，添加开放端口
#firewall-cmd --permanent --zone=public --add-port=3306/tcp
 重新载入
#firewall-cmd --reload

2.2.7. 数据导入

#mysql -uroot -p
Enter password:
mysql> create database sidname default character set utf8 collate utf8_bin;
mysql> grant select,insert,update,delete,create,execute on sidname.* to 'username'@'%' identified by '密码';
mysql> flush privileges;
还原数据库
#mysql -uroot -p'passwd' sidname < /tmp/XXX.sql

参数及部署过程有不足之处，还请多多指教！！
