我们对service和chkconfig两个命令都不陌生，systemctl 是管制服务的主要工具， 它整合了chkconfig 与 service功能于一体。
systemctl is-enabled iptables.service
systemctl is-enabled servicename.service #查询服务是否开机启动
systemctl enable *.service #开机运行服务
systemctl disable *.service #取消开机运行
systemctl start *.service #启动服务
systemctl stop *.service #停止服务
systemctl restart *.service #重启服务
systemctl reload *.service #重新加载服务配置文件
systemctl status *.service #查询服务运行状态
systemctl --failed #显示启动失败的服务
注：*代表某个服务的名字，如http的服务名为httpd
例如在CentOS 7 上安装http
[root@CentOS7 ~]# yum -y install httpd
启动服务（等同于service httpd start）
systemctl start httpd.service
停止服务（等同于service httpd stop）
systemctl stop httpd.service
重启服务（等同于service httpd restart）
systemctl restart httpd.service
查看服务是否运行（等同于service httpd status）
systemctl status httpd.service
开机自启动服务（等同于chkconfig httpd on）
systemctl enable httpd.service
开机时禁用服务（等同于chkconfig httpd on）
systemctl disable httpd.service
查看服务是否开机启动 （等同于chkconfig --list）

Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. Set root password?

By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them.

Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y ... Success!
