构建git项目本地镜像

在服务器上创建一个git用户和用户组

sudo adduser git

根据提示设置对应的信息

设置git home目录的权限为git，否则将来无法访问

sudo chown -R git:git /home/git/

使用git clone --mirror 将github上的项目克隆到本地：

# 创建一个gitmirror目录，用来做镜像中转目录
git@localhost:~$ mkdir gitmirror
git@localhost:~$ cd gitmirror/
# 在githua上添加本地ssh公钥
git@localhost:~/gitmirror$ cat ~/.ssh/
id_rsa       id_rsa.pub   known_hosts  
git@localhost:~/gitmirror$ cat ~/.ssh/id_rsa.pub

#携带--mirror选项将项目克隆到本地

创建我们需要镜像的git项目的目录,并将其初始化为仓库：

git@localhost:~/repos$ mkdir study-rebase.git
git@localhost:~/repos$ cd study-rebase.git/
git@localhost:~/repos/study-rebase.git$ git init --bare       
Initialized empty Git repository in /home/git/repos/study-rebase.git/
git@localhost:~/repos/study-rebase.git$ 

设置项目的本地Repo

#设置项目本地Repo地址
git@localhost:~/gitmirror/study-rebase.git$ git remote set-url --push origin git@172.17.0.1:/home/git/repos/study-rebase.git
#将项目推送到本地Repo
git@localhost:~/gitmirror/study-rebase.git$ git push --mirror
