apache tomcat ajp mod jk

标签：apache   mod_jk   tomcat

环境

系统：centos 7.3

Apache:2.4.27

Modjk:1.2.42

Tomcat:8.5

Jdk:1.8.92

Apr:1.6.2

Apr-util:1.6.0

关闭所有防火墙和selinux

systemctlstop firewalld
serviceiptables stop
setenforce0

一、安装Apache

1、     安装依赖

yum -y install wget gcc gcc-c++ncurses ncurses-devel cmake make perl bison openssl openssl-devel gcc* libxml2libxml2-devel curl-devel libjpeg* libpng* freetype* pcre-devel bzip2-devellibmcrypt-devel  libmhash  libexpat1 libexpat1-dev

2、     安装apr

tar xzvf apr-1.6.2.tar.gz ;cdapr-1.6.2;
./configure--prefix=/usr/local/apr
make && make install

3、     安装apr-util

tar xzvf apr-util-1.6.0.tar.gz ;cdapr-util-1.6.0
./configure--prefix=/usr/local/apr-util --with-apr=/usr/local/apr/
make && make install

4、     安装apache2.4

tar xzvf httpd-2.4.27.tar.gz ;cdhttpd-2.4.27

编译apache之前要把解压后的apr和apr-util复制一分到apache解压后的源码目录中的srclib子目录一，不然会报错。configure: error: BundledAPR requested but not found at ./srclib/. Download and unpack the correspondingapr and apr-util packages to ./srclib/.

cp -a apr-1.6.2httpd-2.4.27/srclib/apr
cp -a apr-util-1.6.0httpd-2.4.27/srclib/apr-util
./configure--prefix=/usr/local/apache --with-included-apr --enable-so--enable-deflate=shared --enable-expires=shared --enable-rewrite=shared--enable-static-support --with-mpm=worker --disable-userdir--enable-proxy-balancer --enable-proxy-http--enable-proxy-connect  --enable-proxy --enable-rewrite--enable-proxy-ajp
make && make install

5、     安装mod jk

tar xzvftomcat-connectors-1.2.42-src.tar.gz ;cd tomcat-connectors-1.2.42-src/native
./configure--with-apxs=/usr/local/apache/bin/apxs
make && make install

二、安装Tomcat

1、   安装jdk

rpm -ivhjdk-8u92-linux-x64.rpm

2、   安装和配置tomcat

tar xzvfapache-tomcat-8.5.15.tar.gz -C /usr/local/

解压两个tomcat,分别命名为tomcat1  tomcat2

因为我们在同一台机上实验，所以要修改第二个tomcat的http和ajp端口，避免端口冲突。这里不再叙述

      修改server.xml如下几个地方

    <Engine name="Catalina" defaultHost="localhost" 
jvmRoute="tomcat1">

      这里添加一个tomcat1，作为等下mod jk转发的路由，另一台为tomcat2

     <Host name="localhost" appBase=""
           unpackWARs="true" autoDeploy="true"
           xmlValidation="false" xmlNamespaceAware="false">
 <Context path="" docBase="/www/1" debug="0"reloadable="false" crossContext="true" />

     这里定义程序网站根目录

         <ValveclassName="org.apache.catalina.valves.AccessLogValve"directory="logs" 
      prefix="localhost_access_log."suffix=".txt" pattern="common"resolveHosts="false"/>

      这里定义日志和格式

3、   启动tomcat

sh /usr/local/tomcat1/bin/catalina.sh start
sh /usr/local/tomcat2/bin/catalina.sh start

测试两个tomcat是否能正常访问，返回200为正常，也可用浏览测试。根据自己改的端口来测试。

curl -I192.168.2.72:8080
curl -I192.168.2.72:8180

三、配置Apache mod jk转发

1、在httpd.conf中找到LoadModule添加

LoadModule jk_module modules/mod_jk.so

打开和添加如下两行，打开vhost和mod_jk的配置

Include conf/extra/httpd-vhosts.conf
Include conf/mod_jk.conf

2、在apache的conf目录下创建mod_jk.conf

#cat mod_jk.conf

JkWorkersFileconf/workers.properties
JkLogFile/usr/local/apache/logs/jk.log
JkShmFile/usr/local/apache/logs/jk-runtime-status
JkLogLevelerror
JkLogStampFormat"[%d %H:%M:%S] "
JkOptions+ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat"%w  %V  %U%q %s  %T"

3、创建workers.properties文件

# cat workers.properties

worker.list=controller,tomcat1,tomcat2
 
# tomcat1
worker.tomcat1.port=8009
worker.tomcat1.host=127.0.0.1
worker.tomcat1.type=ajp13
worker.tomcat1.lbfactor=1
worker.tomcat1.connection_pool_size=500
worker.tomcat1.connection_pool_minsize=25
worker.tomcat1.connection_pool_timeout=300
worker.tomcat1.socket_timeout=20
 
worker.tomcat2.port=8109
worker.tomcat2.host=127.0.0.1
worker.tomcat2.type=ajp13
worker.tomcat2.lbfactor=1
worker.tomcat2.connection_pool_size=500
worker.tomcat2.connection_pool_minsize=25
worker.tomcat2.connection_pool_timeout=300
worker.tomcat2.socket_timeout=20
 
#========controllertomcat online =======
worker.controller.type=lb
worker.controller.balanced_workers=tomcat1,tomcat2
worker.controller.sticky_session=1
worker.controller.connection_pool_size=1000
worker.controller.connection_pool_minsize=50
worker.controller.connection_pool_timeout=300
worker.controller.socket_timeout=20

4、配置httpd-vhosts.conf

<VirtualHost*:80>
        ServerName www.yy.com
        DocumentRoot "/www/1"
        ErrorLog "logs/yy-error_log"
        CustomLog"logs/yy-access_log" common
        JkMount /*.html*    controller
        JkMount /*.tt*    controller
        JkMount /*.index*    controller
     <Directory />
        AllowOverride none
        Options -Indexes
        AllowOverride All
        Require all granted
         </Directory>
</VirtualHost>

[root@node2 www]# ls
1  2
[root@node2 www]# ls *
1:
1.tt  index.html
2:
1.tt  index.html

      /www/1和/www/2分别是tomcat1 和tomcat2的根目录。里面放置一样的文件名，但内容不同。然后刷新浏览器，看内容是否会不停变化，如果会就主明转发成功了。

        JkMount /*.html*    controller

这个是定义所有.html的请求都转发到tomcat处理，这里是实验，生产中应该把动太内容发给tomcat处理，如jsp等。
