fedora / centos 關閉 SELINUX 和 iptables

關閉SELINUX:linux

  修改/etc/selinux/config文件中的SELINUX="" 爲 disabled ,而後重啓。bash

  若是不想重啓系統,使用命令#setenforce 0;tcp

關閉iptables防火牆:spa

sudo systemctl stop firewalld.service         # 暫時關閉,重啓後恢復
sudo systemctl start firewalld.service        # 啓用防火牆
sudo systemctl disable firewalld.service      # 禁用防火牆
sudo systemctl enable firewalld.service       # 啓用防火牆
sudo systemctl status firewalld.service       # 查看狀態

命令配合也是控制其餘linux服務的基本方法。

或開放80端口:rest
