centos下安装、配置zsh & 相关问题解决

【先安装zsh，再安装Oh-My-Zsh】

1. 安装zsh

• 安装ZSH命令：
  - Redhat/Centos yum install zsh
  - Debian/Ubuntu apt-get install zsh

• 设置zsh为默认shell chsh -s $(which zsh)

2. 利用Oh-My-Zsh配置zsh

可以使用curl或wget下载Oh-My-Zsh的安装文件：

• 使用curl安装
  • 命令：sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)”
• 使用wget安装
  • 命令：sh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)”

使用上述命令，可能比较慢，可以采用手动下载的方式进行下载，即直接打开 https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.s将脚本存到服务器，后面使用sh install.sh命令运行安装。

3. 可能会遇到的问题

上述方法在ubuntu、Mac中使用没有问题，非常顺畅，但在centos中遇到了下面这些问题，记录一下。

环境相关信息：

OS版本：CentOS Linux release 7.6.1810 (Core)
kernel版本：3.10.0-957.el7.x86_64

3.1. colors: function definition file not found

该错误类似下面这种情况

尝试网上给出的方法：

1. rm ~/.zcompdump* ，在~路径下没有发现.zcompdump文件
2. 重装 oh-my-zsh

经过上面的尝试都不生效，后来找到了另一个方法，添加$FPATH到 ~/.zshrc配置文件中即可解决该问题。具体为， 在**~/.zshrc**配置文件添加如下语句：

export FPATH=/usr/share/zsh/5.0.2/functions/:$FPATH

上述的/usr/share/zsh/5.0.2/中的5.0.2是zsh版本，可以通过zsh --version或 $SHELL --version命令查看zsh版本信息。

设置完成后，通过source ~/.zshrc 命令即可生效。但自己在执行source ~/.zshrc 命令时有发生了下面的错误。

3.2 syntax error near unexpected token `(’

经过3.1 的修改后，执行source ~/.zshrc 命令时有发生了下面的错误：

--> source ~/.zshrc
-bash: autoload: command not found
-bash: /Users/suy/.oh-my-zsh/oh-my-zsh.sh: line 41: syntax error near unexpected token `('
-bash: /Users/suy/.oh-my-zsh/oh-my-zsh.sh: line 41: `for plugin($plugins); do'

可以通过依次执行下面的命令解决该问题：

zsh
chsh -s $(which zsh)

参考【github】

执行上述chsh -s $(which zsh)命令可能会有 chsh says “invalid shell”类似的提示，解决方法见3.3

3.3 chsh says “invalid shell”

执行chsh -s $(which zsh)命令可能会有 chsh says “invalid shell”类似的提示，解决方法：

Add zsh to /etc/shells:

command -v zsh | sudo tee -a /etc/shells

You can now use chsh to set zsh as shell:

sudo chsh -s "$(command -v zsh)" "${USER}"

参考【stackexchange】

3.4 升级ih-my-zsh

通过在终端中即将入如下命令即可：

upgrade_oh_my_zsh

可参考 【stackoverflow - issue】
