一般git安装完成之后都是使用ssh协议拉取和推送git服务器，如果需要使用http协议的方式，需要一个http容器和额外的配置。这里使用nginx作为http容器。
首先需要安装git和nginx，接着需要安装 libfcgi-dev、 autoconf 、libtool、 automake具体过程请参考https://www.nginx.com/resources/wiki/start/topics/examples/fcgiwrap/
如果想通过源码安装需要下载对应的源码，这里提供一下源码路径
libfcgi源码、autoconf源码、libtool源码、automake源码
注意libfcgi安装时如果出现fcgio.cpp:50:14: error: 'EOF' was not declared in this scope overflow(EOF) 错误，需要在fcgio.cpp的前面添加#include <stdio.h>，fcgio.cpp在libfcgi目录下
https://www.nginx.com/resources/wiki/start/topics/examples/fcgiwrap/ 中安装过程主要有以下几点需要注意
1.安装fcgiwrap之前需要先安装pkg-config
安装方式
./configure --with-internal-glib
make
make install2.启动脚本的bin路径一定要正确，并且不要忘记给脚本执行的权限
我的fcgiwrap在/usr/local/sbin/目录下，所以 $bin_path修改为$bin_path='/usr/local/sbin/fcgiwrap'3.将启动脚本放在rc.local下，这样每次开机就会自动启动
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
/usr/local/sbin/sshd
/usr/local/nginx/sbin/nginx
/etc/init.d/fcgiwrap
exit 0
现在执行这个脚本
root@ubuntu:/# /etc/init.d/fcgiwrap
root@ubuntu:/#
root@ubuntu:/# ps aux | grep fcg
root 2174 0.0 0.1 6444 1324 pts/1 S 15:59 0:00 /usr/local/sbin/fcgiwrap
root 14500 0.0 0.0 6444 672 pts/1 S 16:58 0:00 /usr/local/sbin/fcgiwrap
root 14502 0.0 0.2 15956 2228 pts/1 S+ 16:59 0:00 grep --color=auto fcg
root@ubuntu:/#启动后会在/tmp目录下生成cgi.sock文件，注意启动用户为root。
安装完成，现在需要配置nginx
在conf目录中的nginx.conf文件加入如下配置
server {
listen 8000;
server_name localhost;
root /home/git/repo;
client_max_body_size 100m;
auth_basic "git";
auth_basic_user_file /usr/local/nginx/conf/pass.db;
location ~(/.*) {
fastcgi_pass unix:/tmp/cgi.sock;
fastcgi_param SCRIPT_FILENAME /usr/local/libexec/git-core/git-http-backend;
fastcgi_param PATH_INFO $1;
fastcgi_param GIT_HTTP_EXPORT_ALL "";
fastcgi_param GIT_PROJECT_ROOT /home/git/repo;
fastcgi_param REMOTE_USER $remote_user;
include fastcgi_params;
}
}listen 8000 表示监听8000端口
server_name localhost表示域名localhost
root /home/git/repo 表示请求路径都会到/home/git/repo下进行匹配
例如http://localhost:8000/blog.git 匹配到的的目录是/home/git/repo/blog.git
auth_basic "git" 表示用户名校验为git (如果不需要校验填写off)
auth_basic_user_file /usr/local/nginx/conf/pass.db 为htpasswd 对git和其密码生成的密钥文件。没有安装htpasswd 可以使用在线生成然后将文件拷贝到此（不需要校验请填写off）
在线生成网址http://tool.oschina.net/htpasswd
root@ubuntu:/usr/local/nginx/conf# echo "git:AWoU4Acdd8XLM" >> pass.db
root@ubuntu:/usr/local/nginx/conf#其余需要注意的是fastcgi_param SCRIPT_FILENAME /usr/local/libexec/git-core/git-http-backend这个路径要是正确的如果不知到git-http-backend在哪，可以查找一下
fastcgi_pass unix:/tmp/cgi.sock就是之前执行启动脚本后生成的文件路径
保存文件重启nginx
root@ubuntu:/usr/local/nginx/conf# ps aux | grep nginx
root 2229 0.0 0.0 22444 456 ? Ss 16:11 0:00 nginx: master process ../sbin/nginx
root 2230 0.0 0.3 22836 3052 ? S 16:11 0:00 nginx: worker process
root 14546 0.0 0.2 15956 2172 pts/1 S+ 17:23 0:00 grep --color=auto nginx
root@ubuntu:/usr/local/nginx/conf#注意工作进程用户为root,nginx默认为nobody,修改配置nginx.conf
第一行加上
#user nobody;
user root;
worker_processes 1;
重启，现在就可以使用http协议进行git相关操作了
