配置Apache+tomcat

配置apache + tomcat

① 加载jkMount模块：

在 /etc/httpd/conf/httpd.conf中 LoadModule的地方加上一句

LoadModule jk_module modules/mod_jk.so【可以从其他地方找这个模块】

②在 /etc/httpd/conf.d 下新建一个 mod_jk.conf 文件

JkWorkersFile /etc/httpd/conf/workers.properties
JkLogFile /website/logs/mod_jk.log
JkLogLevel warn
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
JkMount /servlet/* work1
#JkMount /*.jsp work1

这样就完成 JKmount的配置

（一）修改 /etc/httpd/conf.d/vhost.conf 这个是apache的重要配置文件。截图如下

#<VirtualHost *:80>
#        ServerName test.genomics.cn
#        DocumentRoot "/website/webApplications/Events"
#        DirectoryIndex index.jsp
#        JkMount /* work1
#        JkMount /*.do work1
#        JkUnMount /uploadfile/*   work1
#        ErrorLog logs/events-error_log
#        CustomLog logs/events-access_log common
#</VirtualHost>
<VirtualHost *:80>
        ServerName test.genomics.cn
        DocumentRoot "/website/webApplications/BGI"
        DirectoryIndex index.jsp
        JkMount /* work3
        JkMount /*.do work3
        ErrorLog logs/events-error_log
        CustomLog logs/events-access_log common
</VirtualHost>
Listen 9527
<VirtualHost *:9527>
        ServerName test.genomics.cn
        DocumentRoot "/website/webApplications/HIMS_Customer/customer"
        DirectoryIndex index.jsp
        JkMount /* work3
        JkMount /*.do work3
        ErrorLog logs/customer-error_log
        CustomLog logs/customer-access_log common
</VirtualHost>
<VirtualHost *:80>
        ServerName 192.168.224.85
        DocumentRoot "/website/webApplications/GeneBookHttps"
        <Directory /website/webApplications/GeneBookHttps>
           Order allow,deny
           Allow from all
        </Directory>
        DirectoryIndex index.jsp
        JkMount /* work5
        JkMount /*.do work5
        ErrorLog logs/GenebookHttps-error_log
        CustomLog logs/GenebookHttps-access_log common
</VirtualHost>

（二）

配置 apache 跟 tomcat 的交互转发

vim /etc/httpd/conf/workers.properties

# Defining a worker named worker1 and of type ajp13
ps=/
worker.list=work1,work2,work3,work4,work5
# Set properties for TEST
worker.work1.type=ajp13
worker.work1.host=localhost
worker.work1.port=8009
worker.work1.lbfactor=1
#Set properties for BGI
worker.work2.type=ajp13
worker.work2.host=localhost
worker.work2.port=8010
worker.work2.lbfactor=1
#Set for customer
worker.work3.type=ajp13
worker.work3.host=localhost
worker.work3.port=8116
worker.work3.lbfactor=1
#Set for PgappWeb
worker.work4.type=ajp13
worker.work4.host=localhost
worker.work4.port=8011
worker.work4.lbfactor=1

#Set for GenebookHttps
worker.work5.type=ajp13
worker.work5.host=localhost
worker.work5.port=8060
worker.work5.lbfactor=1
可以配置转发多个 ajp13（apache跟tomcat通信的协议）协议的端口也就是多个 tomcat服务

（三）上面 8060端口配置必须和Tomcat 的 ajp1.3协议对应的端口一致

vim $tomcat_home/conf/server.xml

<Connector port="8060" protocol="AJP/1.3" redirectPort="8443" />
这就是 Apache跟 tomcat通信（使用AJP/1.3协议）使用的自定义端口，也是平时开发中很少用到的端口。

其他两个端口分别是关闭的 shutdown端口，和Http协议端口。还有一个用的比较少的是Https的端口。

最后编辑Tomcat的配置文件server.xml，在HOST段中加入：
<Context path="" docBase="/var/wwwroot"
debug="0" reloadable="true" crossContext="true"/>

这样配置之后，可以直接地址栏输入ip地址，即可访问work5对应的项目。

附：机器配置

[**@template icon]$ uname -a
Linux template 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

[**@template icon]$ cat /proc/version

============================================

以下是本人亲自实践的步骤：

cd /usr/local

cp /mnt/hgfs/Share/tomcat-connectors-1.2.37-src.tar.gz ./

tar -zxvf tomcat-connectors-1.2.37-src.tar.gz

cd tomcat-connectors-1.2.37-src/native

apt-get install apache2-prefork-dev anzhuang apxs2

where is apxs2 =========> /usr/lib/apxs2

./configure --with-apxs=/usr/lib/apxs2

make

make install

cp apache-2.0/mod_jk.so /usr/lib/apache2/modules/

后面步骤略，参见：http://www.cnblogs.com/buffer/archive/2009/12/20/1628375.html

[Mon May 19 21:56:50 2014] [notice] SIGHUP received. Attempting to restart
[Mon May 19 21:56:50 2014] [notice] Apache/2.2.22 (Ubuntu) mod_jk/1.2.37 configured -- resuming normal operations

本来apache上面这样启动的时候，已经Ok了，但是结果不加端口（即默认使用80端口）怎么都转发不到tomcat上，网上搜了一个周，有的说加 tomcat_home ,有的说加 java_home 等等，版本神马的，在我这都不好使，结果今天同事说可能是缓存，火狐的缓存全部清空，再访问，果然好了!!!!!!

真是被这个缓存害死。

这样卸载就不会遇到烦人的交互提问，直接卸载干净。
