安装环境：
OS:Redhat Enterprise AS 3
apahce:使用系统自带httpd-2.0.46，使用其它版本的redhat自带的apache安装过程也一样。
Tomcat:Tomcat-5.5.7
jdk：mod_jk:2.0.4
参考：
http://www.reliablepenguin.com/clients/misc/tomcat/ http://www.pixelfreak.net/howto/apache2_jk2_tomcat/socket.html http://www.csse.uwa.edu.au/~ryan/tech/mod_jk2.html http://www.edong.org/main/content/view/386/38/ http://www.pixelfreak.net/howto/apache2_jk2_tomcat/socket.html http://www.cn-java.com/target/news.php?news_id=3043
1. 安装apache
系统自带，无须安装。需要注意的是需要安装httpd开发包，用于编译mod_jk.
查看是否安装httpd-develop
#rpm -qa|grep httpd-devel
httpd-devel-2.0.46-38.ent
如果出现以上信息说明httpd开发包已安装,如果未安装请从redhat第三张盘中安装。
2、安装jdk
从java.sun.com下载jdk-1_5_0_01-linux-i586-rpm.bin，tomcat5需要jdk5的支持。
下载后：
#chmod 755 jdk-1_5_0_01-linux-i586-rpm.bin
#rpm -ivh dk-1_5_0_01-linux-i586.rpm
在/etc/profile文件中加入：
JAVA_HOME=/usr/java/jdk1.5.0_01
export JAVA_HOME
PATH=$PATH:/usr/java/jdk1.5.0_01/bin
export PATH
export CATALINA_HOME=/usr/local/tomcat
export TOMCAT_HOME=/usr/local/tomcat
3.安装Tomcat
#wget http://apache.justdn.org/jakarta/tomcat-5/v5.5.7/bin/jakarta-tomcat-5.5.7.tar.gz
#tar zxvf jakarta-tomcat-5.5.7.tar.gz
#mv jakarta-tomcat-5.5.7 /usr/local/tomcat
4、编译和设置mod_jk
此时注意重新登录服务器使环境变量生效。
#wget http://apache.justdn.org/jakarta/tomcat-connectors/jk2/jakarta-tomcat-connectors-jk2-src-current.tar.gz
#tar zxvf jakarta-tomcat-connectors-jk2-src-current.tar.gz
#cd jakarta-tomcat-connectors-jk2-2.0.4-src/jk/native2/
#./configure --with-apxs2=/usr/sbin/apxs --with-jni --with-apr-lib=/usr/lib
#vi server/apache2/Makefile
将：LIBTOOL=/bin/sh /var/www/build/libtool --silent
改为：LIBTOOL=/usr/bin/libtool
将：
fdef APR_LIBDIR_LA
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt
else
JK_LDFLAGS=-lcrypt ${APR_LIBS}
endif
改为：
ifdef APR_LIBDIR_LA
JK_LDFLAGS=-L${APACHE2_LIBDIR} -lcrypt
else
JK_LDFLAGS=-lcrypt ${APR_LIBS} -lapr-0 -laprutil-0 -lgdbm -ldb-4.1 -lexpat
endif
如果不修改以上内容，将出现以下错误：
INFO: APR not loaded, disabling jni components: java.io.IOException: java.lang.UnsatisfiedLinkError:
/usr/lib/httpd/modules/libjkjni.so:
/usr/lib/libaprutil-0.so.0: undefined symbol: gdbm_errno
或者：
INFO: APR not loaded, disabling jni components: java.io.IOException: java.lang.UnsatisfiedLinkError:
/usr/lib/httpd/modules/libjkjni.so:
/usr/lib/httpd/modules/libjkjni.so: undefined symbol: apr_md5_final
#make
#libtool --finish /usr/lib/httpd/modules
#cp ../build/jk2/apache2/mod_jk2.so ../build/jk2/apache2/libjkjni.so /usr/lib/httpd/modules/
mod_jk安装完毕。
6、配置tomcat
#vi vi /usr/local/tomcat/bin/catalina.sh
# Get standard environment variables
PRGDIR=`dirname "$PRG"`
CATALINA_HOME=`cd "$PRGDIR/.." ; pwd`
if [ -r "$CATALINA_HOME"/bin/setenv.sh ]; then
. "$CATALINA_HOME"/bin/setenv.sh
fi
# 添加以下行
serverRoot=/etc/httpd
export serverRoot
#vi /usr/local/tomcat/conf/jk2.properties
handler.list=apr,request,channelJni
channelUnix.file=/usr/local/tomcat/work/jk2.socket
serverRoot=/etc/httpd
apr.NativeSo=/usr/lib/httpd/modules/libjkjni.so
#vi /usr/local/tomcat/conf/server.xml
在</Engine>前加入
<Host name="www.abc.com" debug="1" appbase="/var/www/abc" unpackwars="true">
<Context path="" docBase="" debug="1"/>
</Host>
配置其它虚拟主机与此同。
7、设置虚拟主机
比如，我现在有虚拟主机 www.abc.com 希望把jsp和servlet都转到tomcat去
在 /etc/httpd/conf/ 下面创建workers2.properties，内容如下：
[shm]
file=/var/log/httpd/shm.file
size=1048576
# Example socket channel, explicitly set port and host.
[channel.socket:localhost:8009]
port=8009
host=127.0.0.1
# Example UNIX domain socket
[channel.un:/usr/local/tomcat/work/jk2.socket]
tomcatId=localhost:8009
debug=0
# define the worker
[ajp13:localhost:8009]
#channel=channel.un:/usr/local/tomcat/work/jk2.socket
# To use the TCP/IP socket instead, just comment out the above
# line, and uncomment the one below
channel=channel.socket:localhost:8009
# Announce a "status" worker
[status:status]
[uri:/status/*]
worker=status:status
# Uri mapping
[uri:/jsp-examples/*]
在/etc/httpd/conf/httpd.conf里面配置：
#tomcat
LoadModule jk2_module modules/mod_jk2.so
JkSet config.file /etc/httpd/conf/workers2.properties
#把下面这段放到VirtualHost之前，可以从全局避免用户用apache访问WEB-INF目录。
<Directory ~ "/WEB-INF/">
Order allow,deny
Deny from all
</Directory>
#典型的VirtualHost配置样本
NameVirtualHost 1.2.3.4 #(1.2.3.4你的服务器IP)
<VirtualHost 1.2.3.4>
ServerName www.abc.com
DocumentRoot /var/www/abc
DirectoryIndex index.htm index.html default.htm index.php index.jsp
<Location ~ "/*.jsp|/*/servlet/*>
JkUriSet worker ajp13:localhost:8009
</Location>
ErrorLog logs/www.abc.com-err_log
CustomLog logs/www.abc.com-acc_log common
</VirtualHost>
这样就可以为每个不同的虚拟主机分别指定使用或者不使用jsp功能。
8、启动、测试
#service httpd start
#/usr/local/tomcat/bin/startup.sh
浏览器里输入
http://1.2.3.4/jsp-examples/
http://1.2.3.4/status/
如果没有问题则说明安装成功。

| [b:8891894ec0]JK2 is officially unsupported![/b:8891894ec0]
http://jakarta.apache.org/tomcat/connectors-doc/ JK2 has been put in maintainer mode and no further development will take place. The reason for shutting down JK2 development was the lack of developers interest. Other reason was lack of users interest in adopting JK2, caused by configuration complexity when compared to JK. JK2 will have it's successor within core Apache2.1/2.2 distribution. We have developed new proxy_ajp that is an addition to the mod_proxy and uses Tomcat's AJP protocol stack. It is developped in httpd-2.1 and integrated in it. We have also developed a new proxy_balancer module for load balancing http and ajp protocol stacks. |

http://1.2.3.4/status/ 也都能访问。只不过不配置还不好。现在比如说http://localhost/jsp-examples/index.jsp能正常访问，但http://localhost/jsp-examples/index.htm不能访问。我还在找原因。 |

[quote:11fc65fa1c]在整合的过程中要注意的是，由于apache、mod_jk2均依赖于apr，所以三者的版本要注意匹配，不要一味求新，不然很容易出现“undefined symbol:apr_socket_send”之类的错误。如果是安装了redhat9和fedora自带的apache，mod_jk2用2.0.2的版本编译就好，用2.0.4的版本编译会有问题。[/quote:11fc65fa1c] |
