【Linux】【Services】【VersionControl】git-daemon, httpd, mysql搭建带认证的gitserver

1. 简介:

比较低端的gitserver,使用centos自带的git-daemon搭建gitserver,使用httpd做上传和下载,利用mod_auth_mysql做认证

2. 环境

# Apache的运行环境
apr-util-mysql.x86_64 1.5.2-6.el7 @base # git server的主进程
git
-daemon.x86_64 1.8.3.1-14.el7_5 @updates # http服务器
httpd.x86_64                                      
2.4.6-80.el7.centos.1 @updates # httpd的开发库
httpd
-devel.x86_64 2.4.6-80.el7.centos.1 @updates # 让httpd支持mysql认证的库
libdbi
-dbd-mysql.x86_64 0.8.3-16.el7 @base # mysql客户端
mariadb.x86_64
1:5.5.56-2.el7 @base # mysql服务器
mariadb
-server.x86_64 1:5.5.56-2.el7 @base # CentOS版本 CentOS Linux release 7.5.1804 (Core)
# 内核版本
Linux centos-0 3.10.0-693.17.1.el7.x86_64 #1 SMP Thu Jan 25 20:13:58 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

 

 

3. 安装

3.1. 安装必要的包

yum install -y git-daemon httpd httpd-devel mariadb mariadb-server libdbi-dbd-mysql apr-util-mysql

  

3.2. 检查httpd安装

# 修改http配置文件
~]# sed  "s/\<ServerName/ServerName YOURSERVERIP:80/g" /etc/httpd/conf/httpd.conf

# alias,cgi,env这三个模块必须要有
~]# httpd -M |grep -Ei "\<(alias|cgi|env)"
 alias_module (shared)
 env_module (shared)
 cgi_module (shared)

~]# systemctl start httpd

  

3.3. 检查git-deamon安装

~]# cat /usr/lib/systemd/system/git@.service
[Unit]
Description=Git Repositories Server Daemon
Documentation=man:git-daemon(1)

[Service]
User=nobody
ExecStart=-/usr/libexec/git-core/git-daemon --base-path=/var/lib/git --export-all --user-path=public_git --syslog --inetd --verbose
StandardInput=socket

~]# systemctl start git.socket

  

3.4. 检查mysql安装

~]# grep -Ev "^#|^$" /usr/lib/systemd/system/mariadb.service
[Unit]
Description=MariaDB database server
After=syslog.target
After=network.target
[Service]
Type=simple
User=mysql
Group=mysql
ExecStartPre=/usr/libexec/mariadb-prepare-db-dir %n
ExecStart=/usr/bin/mysqld_safe --basedir=/usr
ExecStartPost=/usr/libexec/mariadb-wait-ready $MAINPID
TimeoutSec=300
PrivateTmp=true
[Install]
WantedBy=multi-user.target

~]# systemctl start mariadb

  

4. 配置

4.1. 配置git-deamon支持git协议

~]# cd /var/lib/git/
#初始化一个空的目录
~]# git init --bare myproject.git
Initialized empty Git repository in /var/lib/git/myproject.git/
#可以在其他客户端使用git clone git://IPADDRESS/myproject.git尝试下载了,但是目前只能下载,不能推送

  

4.2. 支持http方式的clone

#创建git目录并初始化仓库
~]# mkdir /var/www/git
~]# cd /var/www/git
~]# git init --bare testproject.git
~]# chown -R apache:apache /var/www/git

#修改httpd配置文件的DocumentRoot
sed -i "s/^DocumentRoot/#&/" /etc/httpd/conf/httpd.conf

  

创建/etc/httpd/conf.d/git.conf

<VirtualHost *:80>
        ServerName centos-0
        #下面的参数可以使用man git-http-backend查看
        SetEnv GIT_PROJECT_ROOT /var/www/git
        #检查GIT是否支持smart功能,如果支持就打开smart功能
        SetEnv GIT_HTTP_EXPORT_ALL
        #要授权读或者写主要取决于/usr/libexec/git-core/目录的权限
        ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
        <Directory "/usr/libexec/git-core/">
                Options ExecCGI Indexes
                Require all granted
        </Directory>
</VirtualHost>

  

可以试着clone了

git clone http://IPADDRESS/git/testproject.git

  

但是目前依然不支持推送,如果想要推送需要在git的源上配置

git config http.receivepack true

  

4.3. 配置http支持文件认证

修改/etc/httpd/conf.d/git.conf

<VirtualHost *:80>
        ServerName centos-0
        #下面的参数可以使用man git-http-backend查看
        SetEnv GIT_PROJECT_ROOT /var/www/git
        #检查GIT是否支持smart功能,如果支持就打开smart功能
        SetEnv GIT_HTTP_EXPORT_ALL
        #要授权读或者写主要取决于/usr/libexec/git-core/目录的权限
        ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
        <Directory "/usr/libexec/git-core/">
                Options ExecCGI Indexes
                Require all granted
        </Directory>
        <LocationMatch "^/git/.*/git-receive-pack$">
                AuthType Basic
                AuthName "Private Git Repo"
                AuthUserFile /etc/httpd/conf/.htpasswd
                Require valid-user
        </LocationMatch>
</VirtualHost>

  

添加用户

htpasswd -c -m /etc/httpd/conf/.htpasswd eric

  

4.4. 安装libdbi-dbd-mysql模块,这个模块只支持2.4版本之后,同时还支持pgsql和sqlite,是apache的开源项目

redhat上的介绍:https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system_administrators_guide/ch-web_servers

apache上的介绍:https://httpd.apache.org/docs/2.4/mod/mod_authn_dbd.html

 

配置数据库

# 直接连数据库,没有密码
~]# mysql -uroot
#给root用户设置一个密码
> update mysql.user set password=PASSWORD('mysql') where user='root';
# 创建一个git用户
>CREATE USER 'git'@'localhost' IDENTIFIED BY 'git';
# 创建git库
>create database git;
# 给权限
>GRANT all ON git.* TO 'git'@'localhost';
# 创建一个users表
>create table users ( user_name varchar(191) not null, user_passwd varchar(191), user_group varchar(191), primary key (user_name) );

  

修改配置文件/etc/httpd/conf.d/git.conf

参考 https://www.seei.biz/mysql-authentication-on-apache-2-4/

<VirtualHost *:80>
        #LoadModule mysql_auth_module modules/mod_auth_mysql.so
        ServerName centos-0
        #下面的参数可以使用man git-http-backend查看
        SetEnv GIT_PROJECT_ROOT /var/www/git
        #检查GIT是否支持smart功能,如果支持就打开smart功能
        SetEnv GIT_HTTP_EXPORT_ALL
        #要授权读或者写主要取决于/usr/libexec/git-core/目录的权限
        ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
        #使用Mysql认证方式
        DBDriver mysql
        #数据库参数
        DBDParams "host=localhost dbname=git user=git pass=git"
        # Minimum number of connections
        DBDMin 4
        # Maximum sustained number of connections
        DBDKeep 8
        #Set the hard maximum number of connections per process
        DBDMax 20
        # Set the time to keep idle connections alive when the number of connections specified in DBDKeep has been exceeded
        DBDExptime 300
        <Directory "/usr/libexec/git-core/">
                Options ExecCGI Indexes
                Require all granted
        </Directory>
        <LocationMatch "^/git/.*/git-receive-pack$">
                AuthType Basic
                AuthName "Private Git Repo"
                AuthDBDUserPWQuery "select user_passwd from users where user_name = %s and user_group = 'admin'"
                AuthBasicProvider socache dbd
                #AuthUserFile /etc/httpd/conf/.htpasswd
                Require valid-user
        </LocationMatch>
</VirtualHost>

  

创建一个用户并插入到数据库

# 利用http工具生成密码
~]# htpasswd -bns gitadmin gitadmin
admin:{SHA}0DPiKuNIrrVmD8IUCuw1hQxNqZc=
# 使用git用户连接数据库创建用户
~]# mysql -ugit -p
# 插入一条数据
> INSERT INTO `users` (`user_name`, `user_passwd`, `user_group`) VALUES('admin', '{SHA}0DPiKuNIrrVmD8IUCuw1hQxNqZc=', 'admin');

  

可以使用admin测试喽
