關閉防火牆
啟動： systemctl start firewalld
關閉： systemctl stop firewalld
檢視狀態： systemctl status firewalld
開機禁用： systemctl disable firewalld
開機啟用： systemctl enable firewalld
關閉selinux
檢視 $: getenforce
disabled表示關閉；enforcing表示開啟
$:/usr/sbin/sestatus -v
selinux status: disabled
臨時關閉
setenforce 1 //設定selinux 成為enforcing模式 (開)
setenforce 0 //設定selinux 成為permissive模式（關）
永久關閉
$:vi /etc/selinux/config
將selinux=enforcing改為selinux=disabled
設定後需要重啟才能生效
$:cat /etc/hosts
