Add Server Profiles in iTerm2 for SSH

https://blog.lovian.org/mac/2018/06/12/mac-add-profiles-in-iterm2.html

I. Install iTerm2 on Mac OS

iTerm2 is a powerful terminal emulator on Mac OS. Install it via homebrew:

brew cask install iterm2

After install iTerm2, I would recommand to use oh-my-zsh to replace bash

II. Add Server Profile

Generally, we connect to a remote server via SSH. If you have many servers to connect, it’s better to configure some server profiles to manage them in iTerm2.

1. Write a profile file on local disk

• Create a file on disk, for example, in the folder ~/Workspace

touch ~/Workspace/remote_server_1

• Then edit this file, need password each time when connect to the server

#!/usr/bin/expect -f set user userName set host remote_host_or_ip set timeout -1 spawn ssh $user@$host interact expect eof

• Or set the password as well

#!/usr/bin/expect -f set user userName set host remote_host_or_ip set password passWord set timeout -1 spawn ssh $user@$host expect { "(yes/no)?" {send "yes\n";exp_continue} "password:" {send "$password\n"} } interact expect eof

• Give execution privilege to profile

chmod +x ~/Workspace/remote_server_1

2. Add profile to iTerm2

Open iTerm2, choose Profiles in taskbar, then click Open Profiles, it will show a Profiles window, then click Edit Profiles

click + button is the left-bottom corner:

• Edit Name in Basics to set Profile name, for example server_1
• Edit Tags in Basics to set tag of this profile, for example remote_cluster
• Edit Command in Command: expect ~/Workspace/remote_server_1

III. Use profile to open a SSH session

After configured as above, open iTerm2, click Profiles in the task bar, you will see there is remote_cluster, and there is server_1 inside it. iTerm2 will open a SSH session when you click it.
