CentOS装机常用命令

CentOS 7 ：

1、安装network，才可以使用ifconfig命令查看ip地址：

yum install net-tools

/etc/firewalld/zones/public.xml（firewolld配置文件）/usr/lib/firewalld/services/http.xml（httpd配置文件）

7、关闭firewall防火墙，安装iptables

systemctl stop firewalld.service #停止firewallsystemctl disable firewalld.service #禁止firewall开机启动yum install iptables-services #安装vi /etc/sysconfig/iptables #编辑防火墙配置文件# Firewall configuration written by system-config-firewall# Manual customization of this file is not recommended.*filter:INPUT ACCEPT [0:0]:FORWARD ACCEPT [0:0]:OUTPUT ACCEPT [0:0]-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT-A INPUT -p icmp -j ACCEPT-A INPUT -i lo -j ACCEPT-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT-A INPUT -j REJECT --reject-with icmp-host-prohibited-A FORWARD -j REJECT --reject-with icmp-host-prohibitedCOMMIT:wq! #保存退出systemctl restart iptables.service #最后重启防火墙使配置生效systemctl enable iptables.service #设置防火墙开机启动
