centos7安装zsh和自动补全插件

zsh是一个非常好用的shell，可以根据使用者的喜好和习惯来选择shell结构，让你的shell更美观。

一、安装zsh

  1. 安装zsh包
sudo yum install zsh -y
  1. zsh安装完成后，把系统默认的shell由bash切换为zsh：
chsh -s /bin/zsh  #
  1. 切换后查询一下当前系统的shell
echo $SHELL

如果输出结果为

/bin/bash

说明没有切换过来，可以通过重启服务器以生效。

sudo reboot

二、安装oh-my-zsh

  1. 从gitee下载install.sh
wget https://gitee.com/mirrors/oh-my-zsh/raw/master/tools/install.sh
  1. 将install.sh中仓库修改为gitee地址
sed -i 's/REPO=${REPO:-ohmyzsh/ohmyzsh}/REPO=${REPO:-mirrors/oh-my-zsh}/' install.sh
sed -i 's/REMOTE=${REMOTE:-https://github.com/${REPO}.git}/REMOTE=${REMOTE:-https://gitee.com/${REPO}.git}/' install.sh
  1. 更改install.sh权限
chmod +x install.sh
  1. 执行install.sh
./install.sh

出现以下内容说明安装成功。
在这里插入图片描述

  1. 打开~/.zshrc文件，修改主题ZSH_THEME
ZSH_THEME="af-magic"

可以根据自己的喜好来更换主题

三、安装zsh-autosuggestions插件

zsh-autosuggestions是一个自动补全插件，可以记录你的输入历史，推测你想输入的内容，是个非常便捷好用的插件。

  1. 克隆镜像到本地
git clone https://gitee.com/hailin_cool/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
  1. 打开zshrc文件
vi ~/.zshrc

在.zshrc里面找到plugins，在后面加上zsh-autosuggestions

plugins=(git zsh-autosuggestions)

保存退出，更新~/.zshrc文件

source ~/.zshrc

安装完成
