1.oh my zsh安装
oh-my-zsh依赖于zsh，需要先安装zsh:
yum -y install zsh
如果当前的shell不是zsh，执行
chsh -s /bin/zsh切换shell，然后重启shell。
安装oh my zsh，执行官方的脚本：
zsh -c "$(curl -fsSL https://gitee.com/whereabouts-fork/ohmyzsh/blob/master/tools/install.sh)"
若失败则手动安装：
git clone https://gitee.com/whereabouts-fork/ohmyzsh.git ~/.oh-my-zsh
# 拷贝配置文件
cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
# 应用配置文件
source ~/.zshrc
2.插件安装
下载插件仓库到oh my zsh 的 plugins 目录下，然后修改配置文件添加支持的插件：
vi ~/.zshrc
# i
plugins=(git zsh-autosuggestions zsh-syntax-highlighting)
# esc :wq
# 先安装下述步骤的插件
source ~/.zshrc
2.1 zsh-autosuggestions
git clone https://gitee.com/whereabouts-fork/zsh-autosuggestions.git ~/.oh-my-zsh//plugins/zsh-autosuggestions
2.2 zsh-syntax-highlighting
git clone https://gitee.com/whereabouts-fork/zsh-syntax-highlighting.git ~/.oh-my-zsh//plugins/zsh-syntax-highlighting
