## 系统配置
|
||||
|
||||
!> 未完待续
|
||||
### 更新系统(不能访问外网请忽略)
|
||||
|
||||
```bash
|
||||
yum update -y
|
||||
```
|
||||
|
||||
### 关闭Selinux
|
||||
除非你明确知道它是什么怎么配置,否则不建议开启。
|
||||
|
||||
```bash
|
||||
setenforce 0
|
||||
```
|
||||
上面的命令是临时关闭,仅在当前Session下有效,使用它就不用重启了。
|
||||
永久关闭的命令:
|
||||
|
||||
```bash
|
||||
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
|
||||
```
|
||||
|
||||
### 关闭防火墙
|
||||
|
||||
```bash
|
||||
systemctl stop firewalld
|
||||
systemctl disable firewalld
|
||||
```
