git-daemon-run

$ sudo apt-get install git-daemon-run

安装后会创建下面两个用户

$ cat /etc/passwd | grep git
gitlog:x:117:65534::/nonexistent:/bin/false
gitdaemon:x:118:65534::/nonexistent:/bin/false

git-daemon-run 包携带的文件

$ dpkg -L git-daemon-run
/.
/etc
/etc/sv
/etc/sv/git-daemon
/etc/sv/git-daemon/run
/etc/sv/git-daemon/log
/etc/sv/git-daemon/log/run
/usr
/usr/share
/usr/share/doc
/usr/share/doc/git-daemon-run
/usr/share/doc/git-daemon-run/changelog.gz
/usr/share/doc/git-daemon-run/changelog.Debian.gz
/usr/share/doc/git-daemon-run/README.Debian
/usr/share/doc/git-daemon-run/copyright

同时创建下面配置文件

$ find /etc/sv/git-daemon/
/etc/sv/git-daemon/
/etc/sv/git-daemon/run
/etc/sv/git-daemon/supervise
/etc/sv/git-daemon/log
/etc/sv/git-daemon/log/run
/etc/sv/git-daemon/log/supervise

编辑/etc/sv/git-daemon/run配置

$ sudo vim /etc/sv/git-daemon/run

#!/bin/sh
exec 2>&1
echo 'git-daemon starting.'
exec chpst -ugitdaemon \
"$(git --exec-path)"/git-daemon --verbose --reuseaddr \
--base-path=/var/cache /var/cache/git

git-daemon --verbose --reuseaddr \
--base-path=/var/cache /var/cache/git

改为

git-daemon --verbose --reuseaddr \
--export-all --base-path=/opt/git

提示

* 我加上了一个--export-all 使用该选项后，在git仓库中就不必创建git-daemon-export-ok文件。

/etc/services 文件中加入

# Local services
git             9418/tcp                        # Git Version Control System

确认已经加入

$ grep 9418 /etc/services

启动git-daemon

$ sudo sv stop git-daemon

or

$ sudo runsv git-daemon
runsv git-daemon: fatal: unable to change to directory: file does not exist

扫描git端口，确认git-daemon已经启动

$ nmap localhost

Starting Nmap 5.00 ( http://nmap.org ) at 2012-01-31 10:45 CST
Warning: Hostname localhost resolves to 2 IPs. Using 127.0.0.1.
Interesting ports on localhost (127.0.0.1):
Not shown: 989 closed ports
PORT     STATE SERVICE
21/tcp   open  ftp
22/tcp   open  ssh
53/tcp   open  domain

445/tcp  open  microsoft-ds
1723/tcp open  pptp
3128/tcp open  squid-http
3306/tcp open  mysql
9418/tcp open  git

Testing

$ sudo mkdir -p /opt/git/example.git
$ cd /opt/git/example.git
$ git init
$ sudo vim example.git/.git/config
[receive]
denyCurrentBranch = ignore

$ sudo chown gitdaemon -R /opt/git/*
$ touch git-daemon-export-ok

.git/config 文件应该是下面这样

$ cat example.git/.git/config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true

[receive]
denyCurrentBranch = ignore

git-clone git://localhost/example.git

neo@deployment:/tmp$ git clone git://localhost/example.git example.git
Cloning into example.git...
warning: You appear to have cloned an empty repository.
neo@deployment:/tmp$ cd example.git/
neo@deployment:/tmp/example.git$ echo helloworld > hello.txt
neo@deployment:/tmp/example.git$ git add hello.txt
neo@deployment:/tmp/example.git$ git commit -m 'Initial commit'
[master (root-commit) 65a0f83] Initial commit
1 files changed, 1 insertions(+), 0 deletions(-)

我们添加了一些文件，然后再git clone，可以看到文件数目

$ git-clone git://localhost/example.git
Initialized empty Git repository in /tmp/example/.git/
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0)
