查看当前shell
echo $SHELL
zsh
安装zsh
yum install -y zsh
查看zsh
# 查看安装 zsh
which zsh
# 查看 zsh 版本
zsh --version
#查看支持的shell
cat /etc/shells
zsh已添加到支持的shell中
切换shell为zsh
# 切换zsh shelll
chsh -s /bin/zsh
#重新查看目前默认的shell,已经变为bin/zsh
echo $SHELL
注意：
-
centos需要重启生效 -
.bash_profile等Bash中如有定制的设定时需要迁移至.zshrc文件中。
可以看到此时root用户的交互shell已经发生变化
cat /etc/passwd |grep '^root'
root:x:0:0:root:/root:/bin/zsh
oh-my-zsh
oh-my-zsh 帮我们整理了一些常用的 Zsh 扩展功能和主题,避免重复造轮子，这里使用oh-my-zsh
安装 oh-my-zsh
# githu 访问较慢
wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
sh install.sh
# 或
wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O - | sh
# gitee (国内建议)
wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
sh install.sh
我这里使用gitee下载
[root@izgx8m1d9xjzhjz]~# wget https://gitee.com/mirrors/oh-my-zsh/raw/master/tools/install.sh

[root@izgx8m1d9xjzhjz]~# ls
install.sh
然后给install.sh添加权限：
#install.sh添加权限
chmod +x install.sh
# 执行
./install.sh
如果发现很慢，可以修改为gitee源，编辑install.sh
默认设置
ZSH=${ZSH:-~/.oh-my-zsh}
REPO=${REPO:-ohmyzsh/ohmyzsh}
REMOTE=${REMOTE:-https://github.com/${REPO}.git}
BRANCH=${BRANCH:-master}
将中间两行改为：
REPO=${REPO:-mirrors/oh-my-zsh}
REMOTE=${REMOTE:-https://gitee.com/${REPO}.git}
重新执行即可。
安装成功
[root@izgx8m1d9xjzhjz]~# vim install.sh
[root@izgx8m1d9xjzhjz]~# chmod +x install.sh
[root@izgx8m1d9xjzhjz]~# ./install.sh

Looking for an existing zsh config...
Using the Oh My Zsh template file and adding it to ~/.zshrc.

配置 zsh 主题ys
vim ~/.zshrc
修改主题：
ZSH_THEME="robbyrussell"
#改为
ZSH_THEME="ys"
修改插件：
plugins=(git)
#改为
plugins=(git zsh-syntax-highlighting zsh-autosuggestions)
如果.bash_profile中有配置内容的话，还需要增加一行：
source ~/.bash_profile
更新配置文件
source .zshrc
发现同上报错是正常的，因为我们还没有下载插件，直接就配置了。
安装插件
安装zsh-syntax-highlighting
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
安装zsh-autosuggestions
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
安装完成后，重新更新配置：
source .zshrc
在编辑指令的时候，对于之前使用过的指令，按Tab键即可快速补全，非常好用。
配置zsh主题 powerlevel9k (推荐)
安装
$ git clone https://github.com/bhilburn/powerlevel9k.git ~/.oh-my-zsh/custom/themes/powerlevel9k
编辑 ~/.zshrc来启用主题，在其中将ZSH_THEME 改为
ZSH_THEME="powerlevel9k/powerlevel9k"
如果你还没有安装字体，那么可以使用下面的命令来安装所需字体。
安装 powerline字体
# 下载
git clone https://github.com/powerline/fonts.git
# 进入文件夹并安装
cd fonts
./install.sh
安装 Awesome-Terminal Fonts字体
git clone https://github.com/gabrielelana/awesome-terminal-fonts.git
cd awesome-terminal-fonts
./install.sh
安装nerd-fonts
#下载
git clone https://github.com/ryanoasis/nerd-fonts.git
#安装同上
修改配置文件.zshrc
#Path to your oh-my-zsh installation.
export TERM="xterm-256color"
export ZSH="/root/.oh-my-zsh"
#default
#ZSH_THEME="robbyrussell"
#ZSH_THEME="ys"
ZSH_THEME="powerlevel9k/powerlevel9k"
plugins=(git zsh-autosuggestions)
#plugins=(git zsh-syntax-highlighting zsh-autosuggestions)
source $ZSH/oh-my-zsh.sh
