创建${mirror_name}镜像的过程如下：
1. 在${mirror_name}上创建项目，
        可创建空项目，或从https://github.com/winlinvip/simple-rtmp-server拷贝过来。
2. 在本地虚拟机上：    
        git clone $git_url
        cd $project_dir && git checkout master && git branch 1.0release && git push origin 1.0release
3. 创建同步的branch：    
        git remote add upstream https://github.com/winlinvip/simple-rtmp-server.git
        git fetch upstream    
        git checkout upstream/master -b srs.master
        git checkout upstream/1.0release -b srs.1.0release
4. 执行本同步更新脚本，更新。
        bash $sync_script
