# 创建 /data/repositories 目录用于存放 git 仓库
mkdir -p /data/repositories
# init
cd /data/repositories
git init --bare test.git
# set up user access for git repository
chown -R gituser:gituser /data/repositories
chmod 755 /data/repositories
# 查找 git-shell 所在目录，edit /etc/passwd file，the last line should be changed as follows
gituser:x:500:500::/home/gituser:/usr/local/git/bin/git-shell

If follow the steps above, the location will be /usr/local/git/bin/git-shell, use which git-shell command to check the location

安全目的, 限制 git 账号的 ssh 连接只能是登录 git-shell
