## Q&A
|
||
|
||
### forbedden 403
|
||
|
||
第一种方法给文件夹加上权限，第二种方法切换一个更高级别的账号
|
||
|
||
当然我更建议使用第一种
|
||
|
||
```js
|
||
chmod -R 777 /data
|
||
chmod -R 777 /data/www
|
||
```
|
||
|
||
还不行的话尝试关闭 selinux，具体操作如下：
|
||
|
||
```javascript
|
||
vi /etc/selinux/config
|
||
|
||
#SELINUX=enforcing
|
||
SELINUX=disabled
|
||
```
|
||
|
||
### Could not resolve host: mirrorlist.centos.org Centos 7
|
||
|
||
#### 第一步：进入 /etc/resolv.conf
|
||
|
||
加入文件配置内容如下：
|
||
|
||
```json
|
||
nameserver 9.9.9.9
|
||
```
|
||
|
||
### loaded plugins: fastestmirror, langpacks loading mirror speeds from cached hostfile
|
||
|
||
1.修改插件的配置文件
|
||
|
||
```
|
||
# vi /etc/yum/pluginconf.d/fastestmirror.conf
|
||
```
|
||
|
||
将 enabled=1 改为 enabled=0
|
||
|
||
2.修改 yum 的配置文件
|
||
|
||
```
|
||
# vi /etc/yum.conf
|
||
```
|
||
|
||
将 plugins=1 改为 plugins=0
|
