由于韩国某些不可描述的行为，于是将博客迁移到了日本，采用最新正式版本软件搭建了lnmp服务器环境，发现centos7很多常用命令和centos6区别较大，故简单总结下。

1、防火墙
[CentOS6] iptables
[CentOS7] firewalld

目前已禁用firewalld，启用了iptables

2、主机名
[CentOS6] /etc/sysconfig/network
[CentOS7] /etc/hostname

3、服务相关

启动停止
[CentOS6]
service service_name start
service service_name stop
service sshd restart/status/reload

[CentOS7]
systemctl start service_name
systemctl stop service_name
systemctl restart/status/reload sshd

自启动
[CentOS6]
chkconfig service_name on/off

[CentOS7]
systemctl enable service_name
systemctl disable service_name

服务一览
[CentOS6]
chkconfig –list

[CentOS7]
systemctl list-unit-files
systemctl –type service

强制停止
[CentOS6]
kill -9 <PID>

[CentOS7]
systemctl kill –signal=9 sshd
