• 【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
