CentOS搭建Nginx+Subversion环境（包括多个版本库的配置）

Apache Subversion（简称SVN，svn）

因为某种原因我们需要用Nginx作为Subversion的http前端，但目前没有现成的Nginx+Subversion搭配方式。
而Subversion提供Apache的http处理模块。现在我们通过nginx反向代理给Apache的方式来实现Nginx+Subversion的组合方式。

构建Apache+Subversion的环境:

[root@nginx-apache-svn ~]# yum install httd subversion mod_dav_svn -y
#mod_dav_svn是Apache的svn模块

建立SVN库：

[root@nginx-apache-svn ~]# mkdir -p /home/svn
[root@nginx-apache-svn ~]# cd /home/svn/
[root@nginx-apache-svn svn]# svnadmin create work
[root@nginx-apache-svn svn]# chown -R apache.apache work
[root@nginx-apache-svn svn]# tree work/
work/

添加Subversion账号：(注意只是浏览项目的账户，并不能用它登录SVN)

[root@nginx-apache-svn svn]# htpasswd -c /home/svn/work/conf/passwdfile visitor
New password: visitor#用户名和密码都设为visitor
Re-type new password:visitor
Adding password for user visitor

修改/etc/httpd/conf.d/subversion.conf，内容如下:

<Location /svn/work>
        DAV svn
        SVNPath /home/svn/work
        AuthType Basic
        AuthName "Authorization Realm"
        AuthUserFile /home/svn/work/conf/passwdfile#注意这里的用户，只是通过识证的，通过认证，只能是通过http://ip/svn/项目，去浏览项目，不能跟svn/work/conf/passwd里的svn用户混淆了！
        AuthzSVNAccessFile /home/svn/work/conf/authz
        Require valid-user
</Location>

AuthzSVNAccessFile /home/svn/work/conf/authz特别注意这里也要添加认证用户和权限（不然会认证失败，本文章中是visitor）

修改Apache的端口：

[root@nginx-apache-svn svn]# grep "^Listen" /etc/httpd/conf/httpd.conf
Listen 81

[root@nginx-apache-svn svn]# service iptables stop && setenforce 0
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@nginx-apache-svn svn]# getenforce
Permissive

[root@nginx-apache-svn svn]# /etc/init.d/httpd start
Starting httpd:                                            [  OK  ]
[root@nginx-apache-svn svn]# netstat -lnutp

tcp        0      0 127.0.0.1:25                0.0.0.0:*                   LISTEN      1389/master

tcp        0      0 :::22                       :::*                        LISTEN      1310/sshd

使用Nginx反向代理：

[root@nginx-apache-svn src]# wget http://nginx.org/download/nginx-0.8.55.tar.gz
[root@nginx-apache-svn src]# pwd
/usr/local/src
[root@nginx-apache-svn src]# ls
nginx-0.8.55.tar.gz

[root@nginx-apache-svn nginx-0.8.55]# tar -xzvf nginx-0.8.55.tar.gz && cd nginx-0.8.55

添加nginx账号：

[root@nginx-apache-svn nginx-0.8.55]# useradd -s /bin/false nginx
/bin/false是最严格的禁止login选项，一切服务都不能用。
/sbin/nologin只是不允许login系统

安装依赖包：

[root@nginx-apache-svn nginx-0.8.55]# yum install gcc  pcre-devel openssl-devel  -y

[root@nginx-apache-svn nginx-0.8.55]# ./configure --prefix=/app/server/nginx-0.8.55 \
--with-http_stub_status_module \
--with-http_gzip_static_module

[root@nginx-apache-svn nginx-0.8.55]# make && make install

[root@nginx-apache-svn nginx-0.8.55]# cd /app/server/

[root@nginx-apache-svn server]# ls
nginx-0.8.55
[root@nginx-apache-svn server]# ln -sf nginx-0.8.55/ nginx && cd -

[root@nginx-apache-svn nginx-0.8.55]# ll /app/server/
total 4
lrwxrwxrwx. 1 root root   13 Jul 25 09:36 nginx -> nginx-0.8.55/
drwxr-xr-x. 6 root root 4096 Jul 25 09:35 nginx-0.8.55

配置Nginx反向代理,修改/app/server/nginx/conf/nginx.conf:

server {
    listen       80;
    server_name localhost ;

    location /svn/work {
        proxy_pass  http://127.0.0.1:81/svn/work;
    }

    location / {
        return 404;
    }
}

配置SNV：

[root@nginx-apache-svn conf]# pwd
/home/svn/work/conf

[root@nginx-apache-svn conf]# egrep -v "^$|^#" svnserve.conf
[general]
anon-access = read
auth-access = write
password-db = /home/svn/work/conf/passwd
authz-db = /home/svn/work/conf/authz

[root@nginx-apache-svn conf]# which svnserve
/usr/bin/svnserve
[root@nginx-apache-svn conf]# /usr/bin/svnserve -d -r /home/svn

[root@nginx-apache-svn conf]# netstat -lnutp

[root@nginx-apache-svn work]# cat /home/svn/work/conf/authz
### 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 section name.
### The authorizations follow. An authorization line can refer to:
###  - a single user,
###  - a group of 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 rule with '~'. Rules can
### grant read ('r') access, read-write ('rw') access, or no 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

# [/foo/bar]
# harry = rw
# &joe = r
# * =
[/]
visitor=r
# [repository:/baz/fuz]
# @harry_and_sally = rw
# * = r

svnserve -d -r /home/svn#注意启动的时候，一定不要:svnserve -d -r /home/svn/work

svn co svn://192.168.1.98/work work01#注意略径

真对/home/svn/work/conf/passwd是明文的不安全因素，可以考虑用vim passwd +X去加密passwd文件。(经测试这种方法行不通，无法认别，所以无法用VIM加密passwd文件！！！)

特别要注意关掉selinux:(否则重启会出现认证失败！！！)

[root@NGINX-APACHE-SVN ~]# getenforce

可以配置多个版本库：

主要是两个文件：/var/http/conf.d/subversion.conf  和 /app/server/nginx/conf/nginx.conf
[root@NGINX-APACHE-SVN ~]# egrep -v "(^$|^#)" /etc/httpd/conf.d/subversion.conf
LoadModule dav_svn_module     modules/mod_dav_svn.so
LoadModule authz_svn_module   modules/mod_authz_svn.so
<Location /svn/pro>＃(注意通过http:xxx.xxx.xxx.xxx/xxx访问多个代码库的时候，关键是配置下面的参数)
    DAV svn
    SVNPath /var/www/html/svn/pro
    AuthType Basic
    AuthName "Authorization Realm"
    AuthUserFile /var/www/html/svn/pro/conf/passwdfile ＃可以对不同的项目以不同的配置文件，设不同的密码,达到不同的代码组，不能看对方的代码
    AuthzSVNAccessFile /var/www/html/svn/pro/conf/authz
    Require valid-user
</Location>
<Location /svn/app01>
    DAV svn
    SVNPath /var/www/html/svn/app01
    AuthType Basic
    AuthName "Authorization Realm"
    AuthUserFile /var/www/html/svn/pro/conf/passwdfile
    AuthzSVNAccessFile /var/www/html/svn/pro/conf/authz
    Require valid-user
</Location>
多一个版本库就添加一个[Location].......[/Location]
vi /app/server/nginx/conf/nginx.conf
server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }
	 location /svn/pro {
		proxy_pass http://127.0.0.1:81/svn/pro;
	}
	location /svn/app01 {
		proxy_pass http://127.0.0.1:81/svn/app01;
	}

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
#多一个版本库 就多添加一个location /svn/xxxx {.......}

所有的版本库的svnserver.conf都用相同的这样更于管理:

[root@NGINX-APACHE-SVN ~]# egrep -v "(^$|^#)" /var/www/html/svn/pro/conf/svnserve.conf
[general]
anon-access = read
auth-access = write
password-db = /var/www/html/svn/pro/conf/passwd
authz-db = /var/www/html/svn/pro/conf/authz
[sasl]
 =============================================================================
[root@NGINX-APACHE-SVN ~]# egrep -v "(^$|^#)" /var/www/html/svn/app01/conf/svnserve.conf
[general]
anon-access = read
auth-access = write
password-db = /var/www/html/svn/pro/conf/passwd
authz-db = /var/www/html/svn/pro/conf/authz
[sasl]
[root@NGINX-APACHE-SVN ~]#

这样就OK了可以对于不能的版库，有可以设不同的密码在各自的passwd中。
