GIT SSH多账户配置

1、生成多对公私钥对应多个git服务器并将公钥copy到服务器上

ssh-keygen -t rsa -C "chenyh@yunhetong.net" -f id_rsa_work
ssh-keygen -t rsa -C "hzchenyh@163.com" -f id_rsa_osc

2、配置全局config

# oschina(hzcheyh@163.com)	========================================
Host osc
HostName git.oschina.net
User hzchenyh@163.com
IdentityFile ~/.ssh/id_rsa_osc
# yunhetong(chenyh@yunhetong.net)	========================================
Host yunhetong
HostName 120.20.72.179
Port 7999
User git
IdentityFile ~/.ssh/id_rsa_work

3、ssh测试连通性

#测试ssh到osc的连通性(osc即为上面配置的host别名)
ssh -T git@osc

4、取消git全局name和email配置，并为每个项目设置独立的name和email

#取消git全局config
git config --global --unset user.name
git config --global --unset user.email

#(公司项目)进入项目目录下，为每个项目设置name和email
git config user.name 醉公子
git config user.email chenyh@yunhetong.net

#(自己项目)进入项目目录下，为每个项目设置name和email
git config user.name 醉公子osc
git config user.email hzchenyh@163.com

5、修改每个项目中.git目录下的config文件的配置

[core]
......
[remote "origin"]
#url = ssh://git@120.20.72.179:7999/chenyh/user.git    此为原始URL，经上面的host替换后如下所示
url = ssh://git@yunhetong/chenyh/user.git
fetch = +refs/heads/*:refs/remotes/origin/*
[user]
name = 醉公子
email = chenyh@yunhetong.net

[core]
......
[remote "origin"]
#url = git@git.oschina.net:hzchenyh/jfinal.git
url = git@osc:hzchenyh/jfinalBlog.git
fetch = +refs/heads/*:refs/remotes/origin/*

# 以下表示本地默认分支master和远程分支master的一个对应关系
[branch "master"]
remote = origin
merge = refs/heads/master
[user]
name = 醉公子osc
email = hzchenyh@163.com
