遇见一种权限的问题，
1、vim修改/etc/apache2/httpd.conf文件，提示没有权限。
2、在/Library/WebServer/Documents目录使用vim创建一个新文件，提示没有权限。
最后通过sudo vim XXX的方式解决了。
请问下，这种问题，都需要通过sodu来解决吗？还是有其他解决方案？
是不是除了我自己的home目录，其他的目录都需要sudo？

1. 你用Vim了一文件, 保存提示没有限, 可以使用命令`:w !sudo tee %`解决. 具解:

因为Mac OS的用户默认只是普通用户权限，只对自己的家目录有绝对控制权。sudu是以根用户权限运行命令，所以可以修改所有的文件。
/etc/apache2/httpd.conf 和 /Library/WebServer/Documents 不在你的家目录，所以你没有权限修改。

你可以sudo -s获取超级用户权限，然后怎么编辑都可以。不过一般来说还是建议用sudo vim方式
