linux git server 简易搭建 （ssh访问）

git的服务器搭建，如果无需权限控制，仅团队内部使用，初始化一个服务器仓库，其他人通过ssh访问这个文件夹即可。如需复杂的管理，建议使用gitlab。

yum install git -y

id git
useradd git

su git
cd
mkdir .ssh && chmod 700 .ssh
touch .ssh/authorized_keys && chmod 600 .ssh/authorized_keys
cat /tmp/id_rsa.john.pub >> ~/.ssh/authorized_keys

mkdir -p /opt/git/repo.git
git init --bare /opt/git/repo.git
chown -R git:git /opt/git

cat /etc/shells # see if `git-shell` is already in there. If not...
which git-shell # make sure git-shell is installed on your system.
vim /etc/shells # and add the path to git-shell from last command
chsh git # and enter the path to git-shell, usually: /usr/bin/gitshell

git clone git@ip:/opt/git/repo.git

使用ssh -T git@ip 会看到一个提示

fatal: Interactive git shell is not enabled.
hint: ~/git-shell-commands should exist and have read and execute access.

下面我们可定制欢迎信息，可通过git help shell查看到帮助。

创建文件 /home/git/git-shell-commands/no-interactive-login

内容如下：

#!/bin/sh
printf '%s\n' "Hi $USER! You've successfully authenticated, but I do not"
printf '%s\n' "provide interactive shell access."
exit 128

配置权限：

chmod 500 /home/git -R
chown git:git /home/git -R

再使用ssh -T git@ip ，提示会显示欢迎信息：

Hi git! You've successfully authenticated, but I do not
provide interactive shell access.
