Server 安裝 zsh

不能 sutocomplete 太痛苦了

```
apt-get install zsh
curl -L https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh | sh
```

然後默認zsh


```
chsh -s /bin/zsh
```


遇到問題：

```
$ chsh -s /bin/zsh
You may not change the shell for 'apps'.
$ which zsh
/usr/bin/zsh
$ chsh -s /usr/bin/zsh
You may not change the shell for 'apps'.
```

切換到 root 後跑

```
$ chsh -s /usr/bin/zsh apps
```
