resin服务之二----整合resin+Apache服务

整合resin+Apache服务

1.为什么要整合Apache和resin？

a. 早期的resin，tomcat对httpd服务支持不好。

b.  tomcat，resin对rewrite，expires，gzip功能支持不是很好。

c.  动静分离。

开始安装Apache服务

yum -y install zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-devel gd-devel curl-devel

 

cd /home/peng/tools/

wget http://archive.apache.org/dist/httpd/httpd-2.2.23.tar.gz

tar -zxf httpd-2.2.23.tar.gz

cd httpd-2.2.23

./configure --prefix=/application/apache2.2.23 --enable-deflate --enable-headers --enable-modules=so --enable-so --with-mpm=worker --enable-rewrite

 

make && make install

cd ../

ln -s /application/apache2.2.23/  /application/apache

为Apache编译resin mod_caucho模块

cd /application/resin-3.1.13/

./configure --with-apxs=/application/apache2.2.23/bin/apxs

cd /application/resin/modules/c/src/

make

make install

 

查看多出了mod_caucho.so模块：

[root@data-1-1 src]# ll /application/apache/modules/

total 180

-rw-r--r-- 1 root root   9084 Nov 29 07:00 httpd.exp

-rwxr-xr-x 1 root root 170939 Nov 29 07:05 mod_caucho.so

提示：这个模块很类似Apache+php结合的PHP模块一样，Apache就是通过这个mod_caucho.so模块调用resin解析Java程序的。

在Apache配置文件中查看resin的配置信息

root@data-1-1 src]# tail -9 /application/apache/conf/httpd.conf

#

# mod_caucho Resin Configuration

#

 

LoadModule caucho_module /application/apache2.2.23/modules/mod_caucho.so

 

ResinConfigServer localhost 6800

CauchoConfigCacheDirectory /tmp

CauchoStatus yes

提示:本段内容是编译后嵌入到httpd.conf中的resin相关配置。

启动Apache服务测试

[root@data-1-1 src]# /application/apache/bin/apachectl start

[root@data-1-1 src]# lsof -i :80

COMMAND     PID   USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME

clock-app  2712   root   21u  IPv4 2827507      0t0  TCP www.pp.org:48706->165.254.27.91:http (CLOSE_WAIT)

httpd     22824   root    4u  IPv6 2840404      0t0  TCP *:http (LISTEN)

httpd     22826 daemon    4u  IPv6 2840404      0t0  TCP *:http (LISTEN)

httpd     22828 daemon    4u  IPv6 2840404      0t0  TCP *:http (LISTEN)

httpd     22829 daemon    4u  IPv6 2840404      0t0  TCP *:http (LISTEN)

浏览器上输入地址：http://192.168.1.140/查看结果

出现上述的错误！！

提示：出现这个问题的原因是Apache把请求都转发给了ResinConfigServer local 6800，而默认的6800端口在resin中未生效，所以报了503错误。

 

解决办法：

修改Apache的配置内容

[root@data-1-1 src]# tail -9 /application/apache/conf/httpd.conf

#

# mod_caucho Resin Configuration

#

 

LoadModule caucho_module /application/apache2.2.23/modules/mod_caucho.so

 

ResinConfigServer 192.168.1.140 6911

CauchoConfigCacheDirectory /tmp

CauchoStatus yes

 

重启服务：

[root@data-1-1 src]# /application/apache/bin/apachectl graceful

 再次刷新页面查看显示结果OK了：

在Apache中配置通过resin解析Java程序

可以在httpd.conf配置Apache全部向后转发，也可以通过标签匹配配置部分转发，或者在http-vhost.conf中配置虚拟主机 实现部分向后转发。

在httpd.conf配置Apache全部向后转发

[root@data-1-1 ~]# tail -9 /application/apache/conf/httpd.conf

# mod_caucho Resin Configuration

#

 

LoadModule caucho_module /application/apache2.2.23/modules/mod_caucho.so

 

ResinConfigServer 192.168.1.140 6911

SetHandler caucho-request

CauchoConfigCacheDirectory /tmp

CauchoStatus yes

SetHandler caucho-request是转发的作用，就是由Apache代理的，然后把业务转发给resin，全部都往后抛，如果不加此参数，用户访问会走Apache。如果增加了，当用户访问所有的请求都会有Apache转给resin来处理。因此，当未加参数时默认浏览器内容应为Apache服务的默认也It Works！，增加了SetHandler，出来的结果就是resin的默认页面了。

重启Apache服务测试，查看的内容是resin的默认页面：

当把resin服务停掉后再次查看，所有的请求都丢给resin处理了：

[root@data-1-1 ~]# killall java

再次启动resin服务浏览器上查看又OK了！！！

在Apache中配置虚拟主机转发resin解析

#也可以根据域名虚拟主机只让后端resin处理一部分请求转发

[root@data-1-1 ~]# cd /application/apache/conf/extra/

[root@data-1-1 extra]# cp httpd-vhosts.conf  httpd-vhosts.conf_$(date +%F)

[root@data-1-1 extra]# cat httpd-vhosts.conf

NameVirtualHost *:80

<VirtualHost *:80>

    ServerAdmin  835221922@qq.com

    DocumentRoot "/var/www"

    DirectoryIndex index.html index.htm index.jsp

    ServerName www.peng.cc

    ErrorLog   "logs/peng-error_log"

    CustomLog  "logs/peng-access_log" common

 

   <Directory "/var/www">

   Options -Indexes  FollowSymLinks

   AllowOverride None

   Order allow,deny

   Allow from all

   </Directory>

#Resin Configuration

ResinConfigServer 192.168.1.140 6911

#SetHandler caucho-request

</VirtualHost>

 

修改Apache主配置文件内容：

   395  # Virtual hosts

   396  Include conf/extra/httpd-vhosts.conf     ---》此行注释要打开

[root@data-1-1 ~]# tail -9 /application/apache/conf/httpd.conf

# mod_caucho Resin Configuration

#

 

LoadModule caucho_module /application/apache2.2.23/modules/mod_caucho.so

 

#ResinConfigServer 192.168.1.140 6911    ---》虚拟主机已配置，这里注释掉！

#SetHandler caucho-request

CauchoConfigCacheDirectory /tmp

CauchoStatus yes

[root@data-1-1 www]# mkdir -p /var/www/

[root@data-1-1 www]# echo "www.peng.cc" >/var/www/index.html

[root@data-1-1 www]# echo '<%=99+1%>' > /var/www/index.jsp

 

[root@data-1-1 extra]# /application/apache/bin/apachectl graceful

 

默认实现了动静分离：

[root@data-1-1 extra]# curl 192.168.1.140/index.html                

www.peng.cc

[root@data-1-1 ~]# cat /var/www/index.html

www.peng.cc

 

[root@data-1-1 extra]# curl 192.168.1.140/index.jsp

<html>

<head><title>Resin Default Home Page</title></head>

<body>

<h1 style="background: #ccddff">Resin Default Home Page</h1>

This is the default page for the Resin web server.

<p>

Documentation is available <a href="/resin-doc">here</a>.

<p>

Administration is available <a href="/resin-admin">here</a>.

</body>

</html>

 

[root@data-1-1 extra]# curl 192.168.1.140/test.jsp

99+1=100

[root@data-1-1 ~]# cat /application/resin/webapps/ROOT/test.jsp

99+1=<%=99+1%>

 

 

再次测试：

[root@data-1-1 ~]# cp  /var/www/index.jsp  /var/www/peng.jsp

[root@data-1-1 ~]# cat /var/www/peng.jsp

<%=99+1%>

[root@data-1-1 ~]# curl 192.168.1.140/peng.jsp

<html>

<head><title>404 Not Found</title></head>

<body>

<h1>404 Not Found</h1>

/peng.jsp was not found on this server.

<p /><hr />

<small>

Resin/3.1.13

</small>

</body></html>

注意：如果是Apache解析的话，会解析出来结果；而如果是resin解析的话，会报404的错误，所以解析的结果是404，即是resin做了解析。

 

把jsp文件拷贝到resin默认目录下，又可以解析了:

[root@data-1-1 ~]# cp /var/www/peng.jsp  /application/resin/webapps/ROOT/

[root@data-1-1 ~]# curl 192.168.1.140/peng.jsp                 

100

在apache中配置虚拟主机转发resin解析

配置内容

[root@data-1-1 ~]# cat /application/apache/conf/extra/httpd-vhosts.conf

NameVirtualHost *:80

<VirtualHost *:80>

    DocumentRoot "/var/www"

    DirectoryIndex index.html index.htm index.jsp

   Allow from all

   </Directory>

#Resin Configuration

ResinConfigServer 192.168.1.140 6911

SetHandler caucho-request

</VirtualHost>

启动服务

[root@data-1-1 ~]# /application/apache/bin/apachectl graceful

测试

[root@data-1-1 ~]# curl 192.168.1.140/d.html

<html>

<head><title>404 Not Found</title></head>

<body>

<h1>404 Not Found</h1>

/d.html was not found on this server.

<p /><hr />

<small>

提示：访问请求先到Apache服务，之后抛给后端的resin，后端没有d.html文件，则报了404错误；若停掉resin服务，则会报503错误。

[root@data-1-1 ~]# killall java

[root@data-1-1 ~]# killall java

调整resin配置支持多vhost主机

resin主配置文件添加如下内容

102     <!-- resin Configure at 2016-1-11 -->

103 <server id='peng01' address='192.168.1.140' port='6912' watchdog-port="6922">

104      <http address="*" port="8081"/>

   110      <thread-max>256</thread-max>

   111      <socket-timeout>65s</socket-timeout>

   112      <keepalive-max>128</keepalive-max>

   113      <keepalive-timeout>15s</keepalive-timeout>

   114      </server>

启动脚本修改如下

[root@data-1-1 conf]# cat /etc/init.d/resin-peng

         resind start

        ;;

    *)

       echo "Usage: $0 {start|stop|restart}"

       exit 1

  esac

   exit 0

启动服务

[root@data-1-1 conf]# /etc/init.d/resin-peng restart

测试语法并启动服务：

[root@data-1-1 ~]# /application/apache/bin/apachectl -t

Warning: DocumentRoot [/var/blog] does not exist

httpd: Could not reliably determine the server's fully qualified domain name, using 192.168.10.140 for ServerName

Syntax OK

[root@data-1-1 ~]# mkdir -p /var/blog

[root@data-1-1 ~]# /application/apache/bin/apachectl graceful

 

查看hosts文件：

[root@data-1-1 ~]# cat /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.10.140 data-1-1

192.168.1.140 www.pp.org

 

测试：

[root@data-1-1 ~]# echo www.pp.org >/var/blog/index.html

[root@data-1-1 ~]# curl www.pp.org

www.pp.org

[root@data-1-1 ~]# curl www.pp.org/peng.jsp

100

提示：此时查看的结果都是后端resin的6912给的结果，那么我们想后端resin有不同的站点目录。该怎么解决呢？

修改resin主配置文件

删除如下内容：

227     <!--

注释掉resin主配置中虚拟主机中的http端口内容：

90      <!-- <http address="*" port="8080"/> -->

104      <!--  <http address="*" port="8081"/> -->

启动服务

[root@data-1-1 ~]# killall java

[root@data-1-1 ~]# /application/resin/bin/httpd.sh -server peng start

[root@data-1-1 ~]# /application/resin/bin/httpd.sh -server peng01 start

 

站点目录下会生成peng的目录：

[root@data-1-1 ~]# ll /application/resin/webapps/

drwxr-xr-x  3 root root    4096 Nov 29 16:29 peng

测试

[root@data-1-1 ~]# cat /application/resin/webapps/peng/test.jsp

1+1=<%=1+1%>

[root@data-1-1 ~]# cat /application/resin/webapps/ROOT/test.jsp

99+1=<%=99+1%>

 

修改hosts文件：

[root@data-1-1 ~]# cat /etc/hosts

192.168.1.140 www.peng.cc  www.peng.org blog.peng.cc   blog.peng.org

 

开始测试：

[root@data-1-1 ~]# curl http://www.peng.cc/test.jsp

99+1=100

[root@data-1-1 ~]# curl http://blog.peng.cc/test.jsp

99+1=100

[root@data-1-1 ~]# curl http://blog.peng.org/test.jsp 

1+1=2

[root@data-1-1 ~]# curl http://www.peng.org/test.jsp

1+1=2

 

因为resin主配置文件关掉了8080和8081端口，所以带端口查看会报错：

[root@data-1-1 ~]# curl http://blog.peng.org:8080/test.jsp 

curl: (7) couldn't connect to host

[root@data-1-1 ~]# curl http://blog.peng.org:8081/test.jsp

curl: (7) couldn't connect to host

[root@data-1-1 ~]# curl http://www.peng.org:8081/test.jsp

curl: (7) couldn't connect to host

[root@data-1-1 ~]# curl http://www.peng.org:8080/test.jsp

curl: (7) couldn't connect to host

理解结构图：
