SVN作为新一代代码版本管理工具,有很多优点,管理方便,逻辑明确,安全性高,代码一致性高。SVN数据存储有两种方式,BDB(事务安全表类型)和FSFS(一种不需要数据库的存储系统),为了避免在服务器连接中断时锁住数据,FSFS是一种更安全也更多人使用的方式。SVN的运行方式也有两种,一种是独立服务器,另一种是借助apache服务,各有利弊,下面就介绍一下这两种方式各自的部署步骤。
1、作为独立服务器运行:
①安装svn,使用本地yum源安装,操作系统镜像里自带的就有,yum install svn,具体步骤请参考http://ailurus.blog.51cto.com/4814469/1168336;
②创建版本库:
mkdir /svn/project //创建版本库所在文件夹 svnadmin create--fs-type fsfs /svn/project/first //创建版本库,如果需要使用bdb方式存储,则将fsfs改成bdb即可
③初始化版本库,即导入文件到版本库中:
svn import /home/software file:///svn/project/first--message "初始化版本" //将home文件夹的文件导入版本库 svn list --verbose file:///svn/project/first //查看导入的文件
④启动svn服务,svn服务默认端口为3690,可以使用“netstat -ntlp”命令查看服务启动是否成功:
svnserve -d -r /svn/project/first
⑤修改策略控制文件,vi authz,如果以后要添加用户,就将用户名加在相应的用户组(admin或者user)后面即可:
### This file is an example authorization file for svnserve. ### Its format is identical to that of mod_authz_svn authorization ### files. ### As shown below each section defines authorizations for the path and ### (optional) repository specified by the sectionname. ### The authorizations follow. An authorization line can refer to: ### - a single user, ### - a groupof users defined in a special [groups] section, ### - an alias defined in a special [aliases] section, ### - all authenticated users, using the '$authenticated' token, ### - only anonymous users, using the '$anonymous' token, ### - anyone, using the '*' wildcard. ### ### A match can be inverted by prefixing the rulewith'~'. Rules can ### grantread ('r') access, read-write ('rw') access, orno access ### (''). [aliases] # joe = /C=XZ/ST=Dessert/L=Snake City/O=Snake Oil, Ltd./OU=Research Institute/CN=Joe Average [groups] # harry_and_sally = harry,sally # harry_sally_and_joe = harry,sally,&joe admin=first,second,third //用户组admin包含的成员 user=anyone //用户组user包含的成员 # [/foo/bar] # harry = rw # &joe = r # * = # [repository:/baz/fuz] # @harry_and_sally = rw # * = r [/] @admin=rw //用户组admin内成员拥有读写权限 @user=r //用户组user内成员拥有读权限
⑥添加svn访问用户,vi passwd,为authz里分配的用户设置密码,等号左边为用户名,等号右边是密码;
### This file is an example password file for svnserve. ### Its format is similar to that of svnserve.conf. As shown in the ### example below it contains one section labelled [users]. ### The nameandpasswordfor each user follow, one account per line. [users] # harry = harryssecret # sally = sallyssecret first=first second=second third=third anyone=anyone
⑦修改svn读取的权限策略文件,vi /svn/project/first/conf/svnserve.conf:
anon-access = none //不允许匿名用户读写 auth-access = write password-db = passwd //svn读取的passwd文件 authz-db = authz //svn读取的权限控制文件
⑧安装svn客户端,就可以使用客户端通过如下的url就可以访问了:
svn://IP地址/svn/project/first
2、借助apache服务器,通过web端访问svn:
①给apache服务器安装两个svn插件,这两个插件同样可以使用yum安装:
yum install mod_dav_svn //使subversion与dav模块通信的功能 yum install mod_authz_svn //实现权限控制功能
②使用命令“httpd -M”可以查看是否加载这两个模块,如加载,则有如下回应:
Loaded Modules: core_module (static) mpm_prefork_module (static) http_module (static) so_module (static) auth_basic_module (shared) auth_digest_module (shared) authn_file_module (shared) authn_alias_module (shared) authn_anon_module (shared) authn_dbm_module (shared) authn_default_module (shared) authz_host_module (shared) authz_user_module (shared) authz_owner_module (shared) authz_groupfile_module (shared) authz_dbm_module (shared) authz_default_module (shared) ldap_module (shared) authnz_ldap_module (shared) include_module (shared) log_config_module (shared) logio_module (shared) env_module (shared) ext_filter_module (shared) mime_magic_module (shared) expires_module (shared) deflate_module (shared) headers_module (shared) usertrack_module (shared) setenvif_module (shared) mime_module (shared) dav_module (shared) status_module (shared) autoindex_module (shared) info_module (shared) dav_fs_module (shared) vhost_alias_module (shared) negotiation_module (shared) dir_module (shared) actions_module (shared) speling_module (shared) userdir_module (shared) alias_module (shared) substitute_module (shared) rewrite_module (shared) proxy_module (shared) proxy_balancer_module (shared) proxy_ftp_module (shared) proxy_http_module (shared) proxy_ajp_module (shared) proxy_connect_module (shared) cache_module (shared) suexec_module (shared) disk_cache_module (shared) cgi_module (shared) version_module (shared) authz_ldap_module (shared) dav_svn_module (shared) authz_svn_module (shared) Syntax OK
③编辑apache服务配置文件vi /etc/httpd/conf/httpd.conf,加入下面几行:
<Location /svn> DAV svn SVNPath /svn/project/first AuthzSVNAccessFile /etc/httpd/conf.d/authz //apache服务器读取的权限策略文件 AuthType Basic AuthName "Project" AuthUserFile /etc/httpd/conf.d/passwd //apache服务器读取的密码存储文件 Require valid-user
④编辑文件authz放在文件夹/etc/httpd/conf.d中,文件格式同文章上面的那个authz文件,编辑文件passwd放在文件夹/etc/httpd/conf.d中,使用如下命令生成用户名和密码:
htpasswd -c /svn/project/first admin //命令为htpasswd,-c为参数,/svn/project/first为访问的版本库,admin为用户名
然后重复输入你想设置的密码就可以自动存储在文件passwd中,默认为md5存储。
⑤重启apache服务,就可以在网页端使用刚才设置的用户名密码访问了,网址为http://IP地址:端口/svn.
3、配置多项目创建维护:
其实过程也比较简单,只需要在原来的基础上修改一点信息就可以了。
举个例子,比如有first和second两个项目,要实现多项目的启动管理,只需要修改对应项目配置文件authz的管理路径即可,如下:
单项目:
[/] @admin=rw @user=r
启动:svnserve -d -r /svn/project/first或者svnserve -d -r /svn/project/second,无法同时启动多个项目,因此也就无法同事访问多个项目;
多项目:
[first:/] @admin=rw @user=r [second:/] @admin=rw @user=r
启动:svnserve -d -r /svn/project/,这样就可以启动所有project下的项目了。
很容易理解,但项目里的“/”代表项目根目录,可以使这样“/svn/project/first”或者“/svn/project/second”,多项目里的“/”代表“/svn/project”,在此基础上加上“first:”或者“second:”就切到对应项目里了。
