1. 安装 zsh

查看当前使用的 shell：echo $SHELL
查看当前环境下所有的shell：cat /etc/shells
安装zsh：

MacOS安装：brew install zsh git
CentOS安装：sudo yum -y install zsh git
Ubuntu安装：apt-get update sudo apt-get -y install zsh git

切换默认shell为zsh：sudo chsh -s /bin/zsh
切换回bash：sudo chsh -s /bin/bash

值得注意的是：zsh 在MacOSX上使用 brew 命令的安装的 zsh 路径在/usr/local/bin/zsh，而系统自带的 zsh 默认是在 /bin/zsh，如果需要使用brew安装的zsh，则在/etc/shells中添加一条记录，/usr/local/bin/zsh，也可以直接使用系统自带的zsh也行。

安装完后重开一个terminal执行echo $SHELL 发现当前 shell 已经变为 zsh

2. 安装 oh-my-zsh

有两种安装方式

crul 安装：sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
wget安装：sh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
升级 Oh-My-Zsh：upgrade_oh_my_zsh
卸载 Oh-My-Zsh：uninstall_oh_my_zsh zsh

这里以 curl 的安装方式为例，当出现 oh-my-zsh 就代表安装成功了

Before you scream Oh My Zsh! look over the `.zshrc` file to select plugins, themes, and options.

3. 配置oh-my-zsh

Oh-My-Zsh的默认配置在~/.zshrc文件中配置可以配置，修改默认的基本配置:

ZSH_THEME="robbyrussell"  # zsh主题，可以配置为后面的Dracula主题
export UPDATE_ZSH_DAYS=30 # 30天检查更新zsh
HIST_STAMPS="yyyy-mm-dd"  # 历史记录时间格式
export LANG=en_US.UTF-8   # 语言
plugins=(git autojump zsh-autosuggestions) # 开启常用插件(这些插件都包含在oh-my-zsh中)

autojump命令能够记住我们在命令终端输入的命令，在我们下次使用的时候配合zsh-autosuggestions可以在我们输入命令时给出一些提示，加快我们的命令敲入速度，Oh-My-Zsh插件目录路径在~/.oh-my-zsh/plugins目录下

3.1 优化主题

安装Dracula主题
Dracula在很多编辑器上都可以使用，更多信息可以参考官网

wget -O dracula.zip -c --no-check-certificate https://github.com/dracula/zsh/archive/master.zip
unzip dracula.zip # 解压缩
mv zsh-master/dracula.zsh-theme ~/.oh-my-zsh/themes/ # 将dracula.zsh-theme移动到oh-my-zsh主题目录

wget参数解释-O：自定义存储的文件名 -c：支持断点续传 --no-check-certificate：忽略 https 验证

安装好以后打开~/.zshrc文件修改文件中ZSH_THEME的配置为：dracula，重新打开一个终端或者使用命令source ~/.zshrc重载配置。

报错

如果出现以下错误，执行mv ~/zsh-master/lib ~/.oh-my-zsh/themes/lib即可

/root/.oh-my-zsh/themes/dracula.zsh-theme:source:16: no such file or directory: /root/.oh-my-zsh/themes/lib/async.zsh
bash: async_init: command not found...
bash: async_start_worker: command not found...                                                                                                                                      
bash: async_register_callback: command not found...
bash: async_job: command not found...

3.2 安装插件

Oh-My-Zsh的强大之处是安装各种插件加速我们在命令行终端的体验

zsh-autosuggestions自动补全

下载到$ZSH_CUSTOM/plugins：git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
添加插件到~/.zshrc：plugins=(xxx yyy zsh-autosuggestions)
开启一个新的terminal

autojump

git clone https://github.com/joelthelion/autojump.git cd autojump ./install.py
添加插件到~/.zshrc：plugins=(autojump)
末尾添加[[ -s ~/.autojump/etc/profile.d/autojump.sh ]] && . ~/.autojump/etc/profile.d/autojump.sh
source ~/.zshrc

zsh-syntax-highlighting

git clone https://github.com/zsh-users/zsh-syntax-highlighting $ZSH_CUSTOM/plugins/zsh-syntax-highlighting
添加插件到 ~/.zshrc：plugins=(xxx yyy zsh-syntax-highlighting)
source ~/.zshrc

4. 一些问题

使用 screen：在 ~/.screenrc 文件中添加 shell "/bin/zsh" 来指定 zsh 作为 screen 的默认 shell，不然使用 screen 的时候会出现 zsh: command not found: git_prompt_info
有时候加入了插件无法用，检查一下最后有没有加入 source，或者有没有加入多个 plugins，保留一个列表即可

plugins=(
    autojump 
    zsh-autosuggestions
    zsh-syntax-highlighting
    ) # 开启常用插件(这些插件都包含在oh-my-zsh中)
[[ -s ~/.autojump/etc/profile.d/autojump.sh ]] && . ~/.autojump/etc/profile.d/autojump.sh

source $ZSH/oh-my-zsh.sh
