apache tomcat整合.docx

1、apache tomcat整合一般来讲，配置apache和tomcat的整合有三种方式，mod_proxy,mod_ajp和mod_jk等三种方式，前2种配置步骤类似且 相对容易，且只支持apache2.2以后的版本，mod_jk则配置相对复杂，但强在稳定性和性能方面，因为没有系统的写过这方面的文档，故在此简要的 记录下使用mod_proxy和mod_jk两种方式来整合apache和tomcat！三种方式的对比，具体请参考：本文环境介绍：os版本：centos5.4 64bitjdk版本：jdk-6u2-linux-i586.bintomcat版本：7.0.29apache版本：2.4.2ap

2、ache服务器IP：192.168.123.110/24tomcat实例一IP:192.168.123.110/24 (端口默认)tomcat实例二IP:192.168.123.20/24 (端口默认)一：mod_proxy方式的整合1：编译安装apache，需要编译proxy相关的模块，这里采用目前最新版的apache2.4.21 rootdb1 # tar -zxvpf httpd-2.4.2.tar.gz 2 rootdb1 # cd httpd-2.4.2 3 rootdb1 httpd-2.4.2# ./configure -prefix=/usr/local/apache -ena

3、ble-proxy -enable-proxy-ajp -enable-rewrite -enable-so -enable-headers -enable-expires -enable-modules-shared=most -with-apr=/usr/local/apr/ -with-apr-util=/usr/local/apr-util/ 4 rootdb1 httpd-2.4.2# make 5 rootdb1 httpd-2.4.2# make install 若启动apache出现下面的错误，基本上属于apr的问题，要么apr没安装，要么版本不对！rootdb1 # /usr

4、/local/apache/bin/apachectl -t httpd: Syntax error on line 113 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/modules/mod_proxy.so intoserver: /usr/local/apache/modules/mod_proxy.so: undefined symbol: apr_global_mutex_lockfilerootdb1 # yum remove apr rootdb1 # /usr/local/apache/

5、bin/apachectl -t Syntax OKrootdb1 # /usr/local/apache/bin/apachectl -t -D DUMP_MODULES |grep proxy proxy_module (shared) proxy_connect_module (shared) proxy_ftp_module (shared) proxy_http_module (shared) proxy_fcgi_module (shared) proxy_scgi_module (shared) proxy_ajp_module (shared) proxy_balancer_m

6、odule (shared) proxy_express_module (shared)2：配置apache的虚拟主机1 rootdb1 # /usr/local/apache/bin/apachectl -t -D DUMP_VHOSTS 2 VirtualHost configuration: 3 *:80 is a NameVirtualHost 4 default server 192.168.123.110 (/usr/local/apache/conf/extra/httpd-vhosts.conf:23) 5 port 80 namevhost 192.168.123.110 (

7、/usr/local/apache/conf/extra/httpd-vhosts.conf:23) 6 port 80 namevhost 192.168.123.110 (/usr/local/apache/conf/extra/httpd-vhosts.conf:23) 7 port 80 namevhost (/usr/local/apache/conf/extra/httpd-vhosts.conf:31) 8 port 80 namevhost (/usr/local/apache/conf/extra/httpd-vhosts.conf:31) 若启动apache报错如下，则需要

8、加载mod_slotmem_shm.so模块，之前在使用apache中很少用到mod_proxy模块，所以遇到的问题多多！rootdb1 # /usr/local/apache/bin/apachectl -k start rootdb1 # echo $? 0 rootdb1 # netstat -ntpl |grep :80 rootdb1 # cat /usr/local/apache/logs/error_log Fri Aug 10 18:32:25.298436 2012 proxy_balancer:emerg pid 7859:tid 47937562389216 AH0117

10、 slotmem: is mod_slotmem_shm loaded?

11、start rootdb1 # netstat -ntpl |grep :80 tcp 0 0 :80 :* LISTEN 7898/httpd注意：2.4.2版本的apache中需要在目录下面添加 Require all granted,否则无论怎么访问都是403，悲了个催的！具体报错如下:Fri Aug 10 19:07:13.263893 2012 authz_core:error pid 8918:tid 1126259008 client 192.168.123.102:53420 AH01630: client denied by server configuration: /tm

12、p9 rootdb1 # grep -v # /usr/local/apache/conf/extra/httpd-vhosts.conf |grep -v $ 10 11 ServerName 192.168.123.110 12 13 Order deny,allow 14 Deny from all 15 16 17 18 ServerName 19 DocumentRoot /tmp 20 21 Options +indexes 22 Order allow,deny 23 Allow from all 24 Require all granted 25 26 3：安装jdk和tomc

13、at，并启动tomcat1 rootdb2 # java -version 2 java version 1.6.0 3 OpenJDK Runtime Environment (build 1.6.0-b09) 4 OpenJDK 64-Bit Server VM (build 1.6.0-b09, mixed mode) 5 6 rootdb2 # /usr/local/tomcat7/bin/startup.sh 7 Using CATALINA_BASE: /usr/local/tomcat7 8 Using CATALINA_HOME: /usr/local/tomcat7 9 Us
