centos下安裝、配置zsh & 相關問題解決

【先安裝zsh，再安裝Oh-My-Zsh】

1. 安裝zsh

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

• 設置zsh爲默認shell chsh -s $(which zsh)

2. 利用Oh-My-Zsh配置zsh

可以使用curl或wget下載Oh-My-Zsh的安裝文件：

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

使用上述命令，可能比較慢，可以採用手動下載的方式進行下載，即直接打開 https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.s將腳本存到服務器，後面使用sh install.sh命令運行安裝。

3. 可能會遇到的問題

上述方法在ubuntu、Mac中使用沒有問題，非常順暢，但在centos中遇到了下面這些問題，記錄一下。

環境相關信息：

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

該錯誤類似下面這種情況

嘗試網上給出的方法：

1. rm ~/.zcompdump* ，在~路徑下沒有發現.zcompdump文件
2. 重裝 oh-my-zsh

經過上面的嘗試都不生效，後來找到了另一個方法，添加$FPATH到 ~/.zshrc配置文件中即可解決該問題。具體爲， 在**~/.zshrc**配置文件添加如下語句：

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，可以通過zsh --version或 $SHELL --version命令查看zsh版本信息。

設置完成後，通過source ~/.zshrc 命令即可生效。但自己在執行source ~/.zshrc 命令時有發生了下面的錯誤。

3.2 syntax error near unexpected token `(’

經過3.1 的修改後，執行source ~/.zshrc 命令時有發生了下面的錯誤：

--> 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'

可以通過依次執行下面的命令解決該問題：

zsh
chsh -s $(which zsh)

參考【github】

執行上述chsh -s $(which zsh)命令可能會有 chsh says “invalid shell”類似的提示，解決方法見3.3

3.3 chsh says “invalid shell”

執行chsh -s $(which zsh)命令可能會有 chsh says “invalid shell”類似的提示，解決方法：

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}"

參考【stackexchange】

3.4 升級ih-my-zsh

通過在終端中即將入如下命令即可：

upgrade_oh_my_zsh
