Git 使用初始化

目录

git配置

全局配置

# 查看全局配置
git config --global --list

# 全局配置 用户名和邮箱
git config --global user.name "Your Name"
git config --global user.email "Your Email"

# 默认分支名称
## master -> main
git config --global init.defaultBranch main

# 修改现有分支名称
git branch -m main

本地配置

# 查看本地配置
git config --local --list

# 本地配置 用户名和邮箱
git config --local user.name "Your Name"
git config --local user.email "Your Email"

多用户配置

# ~/.ssh/config
# personal
Host gitee
HostName gitee.com
User Your Name
# 对应的ssh key
IdentityFile ~/.ssh/id_rsa

# work
Host 192.168.1.19
HostName 192.168.1.19
User Your Name
# 对应的ssh key，生成时指定能区分的名字然后写到这里 例：id_rsa_work
IdentityFile ~/.ssh/id_rsa_work

生成SSH密钥

Generating a new SSH key and adding it to the ssh-agent

# 生成SSH密钥
ssh-keygen -t ed25519 -C "[email protected]"

# Note: If you are using a legacy system that doesn't support the Ed25519 algorithm, use:
$ ssh-keygen -t rsa -b 4096 -C "[email protected]"

添加到ssh-agent（可选）

Agent admitted failure to sign using the key

# start the ssh-agent in the background
eval "$(ssh-agent -s)"

# 添加到ssh-agent
ssh-add ~/.ssh/id_ed25519

# 查看ssh-agent
ssh-add -l

自动启动ssh-agent（可选）

在 Git for Windows 上自动启动 ssh-agent

# ~/.bashrc
# 使用Zsh则为 ~/.zshrc
# 复制以下行并将其粘贴到 ~/.bashrc 或 ~/.zshrc 中
env=~/.ssh/agent.env

agent_load_env () { test -f "$env" && . "$env" >| /dev/null ; }

agent_start () {
    (umask 077; ssh-agent >| "$env")
    . "$env" >| /dev/null ; }

agent_load_env

# agent_run_state: 0=agent running w/ key; 1=agent w/o key; 2=agent not running
agent_run_state=$(ssh-add -l >| /dev/null 2>&1; echo $?)

if [ ! "$SSH_AUTH_SOCK" ] || [ $agent_run_state = 2 ]; then
    agent_start
    ssh-add
elif [ "$SSH_AUTH_SOCK" ] && [ $agent_run_state = 1 ]; then
    ssh-add
fi

unset env
