使用gitolite自建立git server

服务器环境如下:

➜  ~ neofetch

      `...`  `...--..`  `...`
            .::::::::::
             `.-::::-`

服务器添加git用户并设置密码

sudo useradd -m git
➜  ~ sudo passwd git
New password:
Retype new password:
passwd: password updated successfully

本地公钥上传到服务器

$ scp ~/.ssh/id_ed25519.pub pi@raspi2b:
pi@raspi2b's password:
id_ed25519.pub                                100%   96     6.9KB/s   00:00

设置公钥,将文件名改为自定义的用户名

➜  ~ sudo cp id_ed25519.pub /home/git/alair.pub
➜  ~ chown -R git:git /home/git/*
➜  ~ sudo chown -R git:git /home/git/*
➜  ~ ll /home/git
total 8.0K
-rw-r--r-- 1 git git   96 Jun 10 16:11 alair.pub
➜  ~

安装gitolite

安装完成后,我们可以看到默认系统建立了两个repo。

git@raspi2b:~/repositories $ ls
gitolite-admin.git  testing.git

我们试着把testing.git pull下来操作下。

$ git clone git@raspi2b:testing.git

管理添加新的repo和用户

gitolite通过一个名为gitolite-admin.git来进行管理,我们可以把他pull下来看下

alair@op36 MINGW64 /d/gits
$ git clone git@raspi2b:gitolite-admin.git
Cloning into 'gitolite-admin'...
remote: Enumerating objects: 6, done.

$ ls -Rl gitolite-admin/
gitolite-admin/:
total 0
drwxr-xr-x 1 alair 197121 0 Jun 10 23:21 conf/
drwxr-xr-x 1 alair 197121 0 Jun 10 23:21 keydir/

gitolite-admin/conf:
total 1
-rw-r--r-- 1 alair 197121 82 Jun 10 23:21 gitolite.conf

gitolite-admin/keydir:
total 1
-rw-r--r-- 1 alair 197121 97 Jun 10 23:21 alair.pub

从上可以看到,gitolite-admin.git包含两个目录,confkeydir,其中conf保存着gitolite.conf配置文件,而keydir保存着上传的公钥文件。

其中keydir中按自定义名保存着公钥文件,如果需要新增用户就在此目录新增用户公钥文件即可。如下,新增一个名为foo的用户。

cp ~/.ssh/foo.pub gitolite-admin/keydir/foo.pub

gitolite-admin/conf/gitolite.conf文件为用户权限配置,如下:

$ cat gitolite-admin/conf/gitolite.conf
repo gitolite-admin
    RW+     =   alair

repo testing
    RW+     =   @all

以上表示repo gitolite-adminalair用户独有,而repo testing的操作权限为所有用户。

我们需要添加新的REPO时,直接在gitolite.conf中新增一行即可,如下:

repo foo
    RW+     =   foo

然后新的gitolite-admin PUSH到服务器即可完成配置。
