create git repository

• 文档 https://www.atlassian.com/git/tutorials/setting-up-a-repository/git-init

Start using Git on the command line

The most common use case for  git init --bare is to create a remote central repository:
$ssh <user>@<host> cd path/above/repo git init --bare my-project.git
or
$git init --bare mautic.git

Initializes a new Git repository and copies files from the  <template_directory> into the repository.
$git init <directory> --template=<template_directory>

$git clone ssh://[email protected]/path/to/my-project.git

Cloning to a specific folder
$git clone <repo> <directory>

Cloning a specific tag
$git clone -branch <tag> <repo>

Shallow clone
$git clone -depth=1 <repo>

clone only the new_feature branch from the remote Git repository.
$git clone -branch new_feature git://remoterepository.git

This means that a repository will be set up with the history of the project that can be pushed and pulled from, but cannot be edited directly.
$git clone --bare

Git URLs, Git has its own URL syntax which is used to pass remote repository locations to Git commands.

Git URL protocols:

-SSH
$ssh://[user@]host.xz[:port]/path/to/repo.git/
$git clone ssh://coober@192.168.0.62/var/workspace/git_respository/mautic.git

-GIT
$git://host.xz[:port]/path/to/repo.git/

- HTTP
http[s]://host.xz[:port]/path/to/repo.git/

git config

Usage
$git config user.email

git config levels and files:

    - --local
    Local configuration values are stored in a file that can be found in the repo's .git directory: .git/config

    - --global
    Global configuration values are stored in a file that is located in a user's home directory. ~ /.gitconfig

    - --system

Writing a value
$git config --global user.email "[email protected]"
$git config --global merge.tool kdiff3
$ git config --global color.ui false

Aliases
$git config --global alias.ci commit
$git config --global alias.amend git ci --amend

$git --version
$git config --global --list
$git pull REMOTE NAME-OF-BRANCH -u

Create a branch
$git checkout -b NAME-OF-BRANCH
$git checkout NAME-OF-BRANCH
$git status
$git add CHANGES IN RED
$git commit -m "DESCRIBE THE INTENTION OF THE COMMIT"
$git push REMOTE NAME-OF-BRANCH

Delete all changes in the Git repository, but leave unstaged things
$git checkout .

Delete all changes in the Git repository, including untracked files
$git clean -f

Merge created branch with master branch
$git checkout NAME-OF-BRANCH
$git merge master

Merge master branch with created branch
$git checkout master
$git merge NAME-OF-BRANCH

GitLab Installation

官网 https://about.gitlab.com/installation/#ubuntu
文档 https://docs.gitlab.com/ee/README.html

1. Install and configure the necessary dependencies
$sudo apt-get install curl openssh-server ca-certificates postfix

2. Add the GitLab package server and install the package
$curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash
$sudo apt-get install gitlab-ce

If you are not comfortable installing the repository through a piped script, you can find the entire script here and select and download the package manually and install using:
dpkg -i gitlab-ce-XXX.deb

3. Configure and start GitLab
sudo gitlab-ctl reconfigure

4. Browse to the hostname and login
The default account's username is root. Provide the password you created earlier and login. After login you can change the username if you wish

GitLab start stop

文档 https://docs.gitlab.com/ee/administration/restart_gitlab.html

Omnibus GitLab restart
$sudo service gitlab-ctl status restart stop start
$sudo gitlab-ctl restart nginx

gitlab-ctl stop unicorn
gitlab-ctl stop sidekiq

$sudo gitlab-ctl kill <service>

Reconfigure Omnibus GitLab with:
$sudo gitlab-ctl reconfigure

GitLab User Account

文档 https://docs.gitlab.com/ee/ssh/README.html

Before generating a new SSH key pair check if your system already has one at the default location by opening a shell, or Command Prompt on Windows, and running the following command:
Windows Command Prompt:
$type %userprofile%\.ssh\id_rsa.pub

Git Bash on Windows / GNU/Linux / macOS / PowerShell:
$cat ~/.ssh/id_rsa.pub


Generating a new SSH key pair
$ssh-keygen -t rsa -C "[email protected]" -b 4096

Note: If you want to change the password of your SSH key pair, you can use
$ssh-keygen -p <keyname>.
