zsh 配置实例

环境：centos6.9 （虚拟机）

1，查看系统当前shell

[root@centos6 ~]# echo $SHELL
/bin/bash
[root@centos6 ~]# 

2，查看当前环境有哪些shell

[root@centos6 ~]# cat /etc/shells 
/bin/sh
/bin/bash
/sbin/nologin
/bin/dash
[root@centos6 ~]#

2.1，我们发现没有zsh，，那么安装zsh

[root@centos6 ~]# yum install zsh

3，切换到zsh

[root@centos6 ~]# chsh -s /bin/zsh
Changing shell for root.
Shell changed.
[root@centos6 ~]#

3.1，再次查看当前shell

[root@centos6 ~]# echo $SHELL
/bin/zsh

• 如果发现还是bash 没关系，，随便打一个常用命令，如果他能自动补全其实就已经切换成功了，重启下就行了

4，下载oh-my-zsh

[root@centos6 ~]# wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh

5，安装和配置
5.1，先安装git

[root@centos6 ~]# yum install git

5.2，修改刚才下载的脚本的权限并安装

[root@centos6 ~]# ls -l
总用量 4
-rw-r--r--. 1 root root 4019 1月  26 06:16 install.sh
[root@centos6 ~]# chmod +x install.sh 
[root@centos6 ~]# ./install.sh

6，zsh的主题文件存放在这里

/root/.oh-my-zsh/themes/

vim /root/.zshrc 

ZSH_THEME="theme_file_name"

8，应用生效

source /root/.zshrc
