1 下载并安装iTerm2

brew install iterm2

安装成功后

brew -v

2 安装solarized主题

1. 下载安装包

   git clone https://github.com/altercation/solarized.git
   

2. 安装
   下载解压Solarized Dark，点击目录solarized\iterm2-colors-solarized的Solarized Dark.itermcolors和 Solarized Light.itermcolors进行安装。

3. iterm2的settings中设置
   

3 安装oh-my-zsh并配置agnoster主题

1. 从github中下载
   “使用 Homebrew 完成 zsh 和 zsh completions 的安装”

brew install zsh zsh-completions

curl -L https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh | sh

2. 修改主题

vim ~/.zshrc    //进入.zshrc文件，将ZSH_THEME后面字段改为agnoster

4 设置powerline

iterm2勾选上

5 隐藏用户名信息

一般终端每一行前都会有xxx@xxxdeMacbook-Pro:我们可以将其隐藏掉。
进入oh-my-zsh的agnoster主题，编辑agnoster.zsh-theme文件：

 vim ~/.oh-my-zsh/themes/agnoster.zsh-theme

注释掉这一行，效果如下

6 设置语法高亮和代码自动补全

在oh-my-zsh存储库中克隆存储库:

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

在.zshrc中插入下面内容：

plugins=(
  git
  zsh-completions
)
autoload -U compinit && compinit

直接使用homebrew安装zsh-syntax-highlighting插件

brew install zsh-syntax-highlighting

然后在根目录下.zshrc中插入下面内容：

source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

在.zshrc中插入下面内容：

plugins=(
  git
  zsh-completions
  zsh-syntax-highlighting
)

zsh-autosuggestions：补全的是历史输入的命令，点击方向键->即可补全

brew install zsh-autosuggestions

在.zshrc中插入下面内容：

plugins=(
  git
  zsh-completions
  zsh-autosuggestions
  zsh-syntax-highlighting
)

7 （可选）如果出现plugin ‘zsh-autosuggestions’ not found

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ~/.oh-my-zsh/custom/plugins/zsh-syntax-highlighting

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

source ~/.zshrc
