Install and Update autojump and oh-my-zsh Behind a Firewall

Brief installation steps:

1. Install git and zsh via yum;

2. 'git clone' autojump and oh-my-zsh from an internet-connected host;

3. Install autojump and oh-my-zsh manually according to the instructions on their websites.

Install

# yum install zsh

# yum install git

$ ssh-copy-id chad@10.21.3.31 (run "ssh-keygen" if have no key)

$ git clone chad@10.21.3.31:/home/chad/.oh-my-zsh

$ cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc

$ git clone chad@10.21.3.31:/home/chad/docs/tmp/autojump (you need 'git clone' from internet on host 31 beforehand)

$ cd autojump;./install.sh   (after installation, add some text into ~/.zshrc according to its prompt)

add "autojump" into "plugins" of ~/.zshrc

$ chsh -s /bin/zsh

restart zsh

Update

The server 10.0.2.74 is behind firewall, and the auto-update is blocked. The oh-my-zsh on laptop 10.21.3.139 is updated. To enable auto-update on server 74, modify update target repo: modify ~/.oh-my-zsh/.git/config: [remote "origin"] -> url from

https://github.com/robbyrussell/oh-my-zsh.git

to

lichao@10.21.3.139:/home/lichao/.oh-my-zsh/.git

Now you can update oh-my-zsh automatically or manually:

$ cd

$ upgrade_oh_my_zsh

Note:

1. You must copy public key of 74 to 139:

   ssh-copy-id lichao@10.21.3.139

2. You can't add "ssh://" before "lichao@...". It complains "ssh could not resolve hostname 10.21.3.139" , Why?

3. On internet-connected Ubuntu host, you can install autojump with 'apt-get install autojump'.
