git常用操作

更换远程分支

• 先删除远程分支：
  git remote rm origin
• 再添加远程分支：
  git remote add origin <origin_url>

新建、删除本地分支，以及删除远程分支

• 新建本地分支
  git branch <new_branch_name>
• 删除本地分支
  git branch -d <local_branch_name>
• 删除远程分支
  git push origin --delete <remote_branch_name>

获取远程分支

• 不重新命名
  git checkout <remote_branch_name>
• 重新命名
  git checkout -b <local_branch_name> <remote_branch_name>

git提交，及提交到远程分支
git push origin <remote_branch_name>:<local_branch_name>

初始化git配置

• 配置用户名，邮箱
  git config --global user.name <user_name>
  git config --global user.email <user_email>
• 配置SSH
  • 生成ssh-key

        $ ssh-keygen -t rsa -C "idioticmadman@qq.com"
        Generating public/private rsa key pair.
        Enter file in which to save the key (/c/Users/robert/.ssh/id_rsa):
        Created directory '/c/Users/robert/.ssh'.
        Enter passphrase (empty for no passphrase):
        Enter same passphrase again:
        Your identification has been saved in /c/Users/robert/.ssh/id_rsa.
        Your public key has been saved in /c/Users/robert/.ssh/id_rsa.pub.
        The key fingerprint is:
        SHA256:UNSglMH1hfsrjrMI3tX8/tKHE/WOoTeLtoENs9VHwok idioticmadman@qq.com
        The key's randomart image is:
        +---[RSA 2048]----+
        |     .o==o ..    |
        |     .oo .o. o . |
        |      o   ..E + .|
        |       .  .  . o.|
        |        S o.. ..o|
        |         o B. o..|
        |    .   . = o+ * |
        |   . o o....=oB o|
        |    . o o+.+==o= |
        +----[SHA256]-----+
    

  • 把公钥添加到git服务器

配置多Git服务器
在.ssh文件夹下新建config文件

config文件：

   # gitlab
     Host 192.168.10.52
     HostName 192.168.10.52
     PreferredAuthentications publickey
     IdentityFile ~/.ssh/funtsui_rsa 
  # github
     Host github.com
     HostName github.com 
     PreferredAuthentications publickey
     IdentityFile ~/.ssh/id_rsa 

配置submodule
添加git的子仓库
git submodule add <repository addr> <directory>
初始化子仓库
git submodule init
更新子仓库
git submodule update

tag相关操作
git tag <name> -m <message> 新增tag
git tag -d <name> 删除tag
git push origin <tag_name> 上传tag到远端
git push origin :refs/tags/<tag_name> 删除远端tag
