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 [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 |

调整resin配置支持多vhost主机
resin主配置文件添加如下内容
|

修改resin主配置文件
