Linux 安装 ZSH 并为之配置主题和 OhMyZsh

一、查看当前的 Shell

$ cat 
/etc/shells 
/bin/sh 
/bin/bash 
/usr/bin/sh 
/usr/bin/bash 
$ echo $SHELL 
/bin/bash

二、安装 ZSH 包

CentOS 系统

$ yum -y install zsh

Debian/Ubuntu 系统

$ apt-get install -y zsh

三、切换默认 Shell 为 OhMyZsh

这里需要切换到你需要安装的用户(比如 root)来执行

$ chsh -s /bin/zsh

如果 CentOS 系统提示 chsh commond not found 的话，则执行以下命令(dnf 为 CentOS7 以后的包管理器，在此之前的系统请使用 yum，以下同理，不在做同样的说明)

$ chsh -s /bin/zsh root 
-bash: chsh: command not found 
$ dnf install util-linux-user

要安装 OhMyZsh，还需要先安装 git

$ dnf install git

然后检查一下，如果不行就 exit 退出当前用户登录，然后重新登录再检查一遍

$ su 
$ echo $SHELL 
/bin/zsh

四、重启服务器

重启服务器让修改的配置生效，这个没什么好多说的

五、安装 OhMyZsh

OhMyZsh 是一个非常好用的工具，想了解更多关于 OhMyZsh 的内容请查看它的 文档。使用 curl 或 wget 均可以安装 OhMyZsh。curl 命令如下

$ curl sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

$ wget sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"

如果安装过程中出现错误如下:
正在连接 raw.githubusercontent.com (raw.githubusercontent.com)|::|:443... 失败：拒绝连接。
此时，可以采用以下方法安装

1. 先用 git 下载 ohmyzsh 项目到本地

   $ git clone git://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh

2. 将 zshrc 替换掉

   $ cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

3. 重启终端即可看到安装成功

六、修改 OhMyZsh 主题

OhMyZsh 可用主题可以使用如下命令罗列。通过命令 vim ~/.zshrc 可以看到默认的主题是 ZSH_THEME="robbyrussell"，改成自己喜欢的即可
