安装centos7.2,发现与之前版本有很大的不同

1  配置163yum源

参考http://mirrors.163.com/.help/CentOS7

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

下载

yum clean all

yum makecache

2 Centos7关闭防火墙

Q:防火墙配置后执行service iptables save 出现”Failed to restart iptables.service: Unit iptables.service failed to load: No such file or directory.”

解决:

在CentOS7或RHEL7中防火墙由firewalld来管理,当然你可以还原传统的管理方式。或则使用新的命令进行管理。

a 假如采用传统请执行一下命令:

systemctl stop firewalld

systemctl mask firewalld

查看防火墙是否打开:

iptables -L

b 使用新的命令进行管理

安装iptables-services:

yum install iptables-services

设置开机启动:

systemctl enable iptables

使用:

systemctl [stop|start|restart] iptables

#or

service iptables [stop|start|restart]

service iptables save

#or

/usr/libexec/iptables/iptables.init save

3 centos7.2启动服务
