第一种：首先安装zsh
yum -y install zsh

下载 oh-my-zsh 项目来帮我们配置 zsh，采用wget安装(需要先安装git)

sh -c "$(wget https://github.com/ohmyzsh/ohmyzsh/blob/master/tools/install.sh -O -)"

切换zsh
chsh -s /bin/zsh

语法高亮
安装插件highlight，高亮语法：

cd /.oh-my-zsh/custom/plugins &&
git clone git://github.com/zsh-users/zsh-syntax-highlighting.git
在Oh-my-zsh的配置文件中/.zshrc中添加插件

plugins=(zsh-syntax-highlighting)
重新打开终端即可生效！

第二种：
查看当前shell

echo $SHELL

返回结果:

bin/bash

安装zsh

yum install -y zsh

静候安装完成...

成功后如下所示

设置默认shell

chsh -s /bin/zsh

请在root用户下切换shell

安装git

自动和手动安装都需要安装git，执行

yum install -y git

静候安装完成,完成后选择一种oh-my-zsh的安装方式。
安装oh-my-zsh（自动）

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

使用curl来安装，wget命令执行后不起作用，暂时不知道怎么回事。

�出现以下界面，显示安装成功。

手动安装

�下载源码

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

复制配置

cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
修改主题

ZSH_THEME 字段就是主题，可以从资料里的主题找

完成后，重启生效默认shell

reboot
别名配置

首先我们看下git的别名

vi ~/.oh-my-zsh/plugins/git/git.plugin.zsh

很强大有木有，我们还可以自定义别名，在~/.zshrc中，最下面直接写即可。

开启常用插件：

plugins=(git autojump zsh-completions systemd yum wd common-aliases git-flow grails rvm history-substring-search github gradle svn node npm zsh-syntax-h ighlighting sublime)

引用更改并立刻生效：

source ~/.zshrc

注意： 在自动下载my zsh的时候可能是访问不到网站，所以应该手动下载，在root下面新建一个文件 install.sh， fq直接打开https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh保存此脚本到本机。（不会fq的可以直接复制下面代码保存）

执行sudo sh ./install.sh,看到安装成功了。
将下面的内容复制到文件中，执行即可成功下载：

!/bin/sh

This script should be run via curl:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

or via wget:

sh -c "$(wget -qO- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

or via fetch:

sh -c "$(fetch -o - https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

As an alternative, you can first download the install script and run it afterwards:

wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh

sh install.sh

You can tweak the install behavior by setting variables when running the script. For

example, to change the path to the Oh My Zsh repository:

ZSH=~/.zsh sh install.sh

Respects the following environment variables:

ZSH - path to the Oh My Zsh repository folder (default: $HOME/.oh-my-zsh)

REPO - name of the GitHub repo to install from (default: ohmyzsh/ohmyzsh)

REMOTE - full remote URL of the git repo to install (default: GitHub via HTTPS)

BRANCH - branch to check out immediately after install (default: master)

Other options:

CHSH - 'no' means the installer will not change the default shell (default: yes)

RUNZSH - 'no' means the installer will not run zsh after the install (default: yes)

KEEP_ZSHRC - 'yes' means the installer will not replace an existing .zshrc (default: no)

You can also pass some arguments to the install script to set some these options:

--skip-chsh: has the same behavior as setting CHSH to 'no'

--unattended: sets both CHSH and RUNZSH to 'no'

--keep-zshrc: sets KEEP_ZSHRC to 'yes'

For example:

sh install.sh --unattended

or:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" "" --unattended

set -e

Default settings

ZSH={REPO:-ohmyzsh/ohmyzsh}
REMOTE={REPO}.git}
BRANCH=${BRANCH:-master}

Other options

CHSH={RUNZSH:-yes}
KEEP_ZSHRC=${KEEP_ZSHRC:-no}
