分两步

配置成功前（wordpress 安装数据库时，安装主题，安装插件等）

```
chown www:www -R * # Let Apache be owner
find . -type d -exec chmod 755 {} \;  # Change directory permissions rwxr-xr-x
find . -type f -exec chmod 644 {} \;  # Change file permissions rw-r--r--
```

配置成功后

```
chown <username>:<username>  -R * # Let your useraccount be owner
chown www:www wp-content # Let apache be owner of wp-content
chown www:www wp-content/uploads -R
chmod 777 wp-content/uploads -R
```
