一般来说，直接访问官网查看具体的安装流程 https://ohmyz.sh/

# centos
yum instal zsh
# ubuntu 或者 debian
sudo apt install zsh

然后下载 oh-my-zsh 安装脚本

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

执行完之后，推荐安装一个热门插件: zsh-autosuggestions

查看安装帮助：https://github.com/zsh-users/zsh-autosuggestions/blob/master/INSTALL.md

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

然后修改 zsh 配置文件

vi ~/.zshrc

核心配置，增加刚刚的那个插件

plugins=(git zsh-autosuggestions)

在刷新一下

source ~/.zshrc
