my_Linux_config

A set of my Linux config, for copy my work config quickly cross different Linux env, now which is Ubuntu.

When you encounter problems with downloading, pay attention to the vpn problem. You can try below ways to solve this issue:

1. If you used shadowsocksR before, you can try switching to a node using Vmess and you will be successful.
2. Set up vpn network proxy for your terminal.
3. Set up vpn network proxy for your git.

2 and 3 we have config in bashrc and config.fish, which is in the proxy_on function, so you can first cp this two config scripts to your home, let them take effect, notice! they won't effect only after you run proxy_on command in shell.

Version illustration

v1.0 is basic config, with the increasement of v1.0./x means there are more features add to config, but means higher perfromance consumption, you can tailored to individual needs to select a suitable version to config your system.

v1.x have the same principle, but this version have higher requirements for your system version, for example, now to use lazyvim in v1.1 to config the neovim, your neovim need to highter than 0.8.0, but Ubuntu22.04 auto install the 0.6.0, which is not satisfy its need, so v1.1 need a lot update to solve this limitation.

v1.0 (basic config): bash/fish/tmux/oh-my-posh/oh-my-fish/vimrc v1.0.1 (more feature basic config) : base on v1.0, add ranger to manage file system v1.1. : bash/fish/tmux/oh-my-posh/oh-my-fish/vimrc v1.2 : add ranger

Hypothesis

You are on a Linux system, doc only test on Ubuntu18.04/22.04/24.04.

• git, version 1.9.5 or later

• apt install can use

• You have a user account on your Linux system

• fzf only can be apt installed on 24.04, so we remove it from auto script

  # Create an account for yourself
  $ sudo useradd -d "/home/moon" -m -s "/bin/bash" moon
  # If you forget your password
  sudo passwd moon
  # login as moon
  su moon

Method

Step 1 Generate and Add ssh key github and your system

reference

Generate a ssh key pair on your system

ssh-keygen -t ed25519 -C "[email protected]"

Add it to your github setting

Now, you have a ssh key in /home/<user_name>/.ssh/, whose names are ed25519 and ed25519.pub, copy public key to github setting.

You can get it use this command

cat ~/.ssh/id_ed25519.pub

Add it to your system ssh agent

ssh-add [path-to-your-key]
ssh-add ~/.ssh/id_ed25519

Note: if you encounter this error Could not open a connection to your authentication agent., which is because you haven't start the SSH agent

Start your ssh agent

If the SSH agent isn't running, you'll need to start it manually.

For bash shell:

eval $(ssh-agent)

For fish shell:

eval (ssh-agent)

This will start the agent and make it available to handle SSH key operations.

Step 2 Clone and Run run_config.sh

Clone git repo and run

git clone [email protected]:InitialMoon/my_linux_config.git
cd my_linux_config
chmod +x run_config.sh
./run_config.sh

During the installation process, you may be prompted to enter your user password. Additionally, if Oh My Fish (OMF) is reinstalled, you might be asked to confirm the reinstallation by entering "y".

when this occur :moon is not in the sudoers file. This incident will be reported

If you encounter "moon is not in the sudoers file. This incident will be reported" error, means user moon not authorized sudo command permissions. To solve this problem, add moon user to sudoers file，but now you can't use sudo，you need another user who has sudo permissions to do this thing.

Solution

1. Switch to a user with administrator privileges: If you have another administrator user (e.g., root), you can log in as that user:

   su - root

2. Edit the sudoers file: Use the visudo command to safely edit the sudoers file. visudo is the recommended tool for editing this file because it checks for syntax errors.

   visudo

   Find the following section (or add it at the end of the file):

   # User privilege specification
   root    ALL=(ALL:ALL) ALL

   Add the following line below it to add the moon user to the sudoers file:

   moon    ALL=(ALL:ALL) ALL

3. Save and exit: In visudo, press Ctrl+X or Esc to exit edit mode, and then save the file.

4. Exit root: Log out of the root user and return to the moon user:

   exit

5. Test sudo permissions: You can now test whether you have gained sudo privileges:

   sudo whoami

   If it returns root, you have successfully configured sudo access.

If you cannot access the root user

If you are unable to switch to root, you may need to use recovery mode or single-user mode (during system startup) to gain root access and perform the above steps.

Be careful when editing the sudoers file, as syntax errors can result in losing sudo access. Using visudo helps prevent such errors.

Step 3 Install tmux plugin

I have install the omf and setting some config in .tmux.conf for you, but you have to activate tmux and use perfix + I to install plugin, perfix is Ctrl+d

Step 4 Setting Fish to default shell

chsh -s /usr/bin/fish

Step 5 Install omf themes（if omf not effect）

omf install bobthefish
omf theme bobthefish
omf doctor
echo 'set theme_color_scheme nord' >> ~/.config/fish/config.fish # if not effect, use below command
set theme_color_scheme nord # only effect once

omf install https://github.com/h-matsuo/fish-color-scheme-switcher
echo 'scheme set catppuccin' >> ~/.config/fish/config.fish# if not effect, use below command
scheme set catppuccin # only once

omf reload

BugFix method: CheckOut wether your config success

If you find some config is not right, you can refer to below:

1. If you find oh-my-fish didn't installed correctly, you can run the run_config.sh again
2. If your font didn't display correctly, install Nerd font on your system, which is the computer which exactly display all the graphics you are looking at
3. If your fish start report error, no such file or directory, which because your configuration in ~/.config/fish/config.fish set catppuccin and another theme have file didn't exist, this is a bug which not fixed in this config script, you can remove this two lines, then restart the fish, this error while be removed, you can set theme manually.
4. nvim setting you need to open nvim, then use :LazyExtras command to select what plugins you want to use, this script will add some plugin usually using: markdown, treesitter, yank, mini_animate, fzf

Other things TODO

if pip3 is installed, you can install tldr, you maybe config your python env before this step

Mac use tmux and iTerm2

If you want to use .tmux.conf on mac in iTerm2 terminal, please care for the option key's setting. We know that option on mac is similar to the key on windows keylayout, but when you use option in iTerm2, which is not look as function key by default. Because of that, you need to follow below steps to set your iTerm2 look option as function key, rather than normal mode, in iterm2, function keys have 3 modes: normal, meta and esc+, you need to set it as esc+ mode, after this, you can use option as alt, then follow your original custom.

In iTerm2, you need to ensure that the Option key is correctly configured to send the Meta key. By default, iTerm2 uses the Option key to input special characters (e.g., ∆). To configure iTerm2 to send the Option key as the Meta key, follow these steps: 1. Open iTerm2 preferences. 2. Go to the Profiles tab. 3. Select the profile you are using. 4. In the Keys tab, locate the settings for Left Option Key and Right Option Key. 5. Set both options to Esc+, so iTerm2 will send the Option key as the Meta key.
