First,Installing Apache

1. Installation Dependencies

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. Install Apr

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

3. Installing 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. Installing apache2.4

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

Before compiling Apache to be extracted after the APR and Apr-util copy a point to Apache extracted from the source directory of the Srclib subdirectory one, or will error. Configure:error:BundledAPR requested but not found at./srclib/. Download and unpack the CORRESPONDINGAPR and Apr-util packages to./srclib/.

5. Install 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/apxsmake && make Install

Second,Installing Tomcat

1. Installing the JDK

rpm-ivhjdk-8u92-linux-x64.rpm

2. Installing and configuring Tomcat

Tar xzvfapache-tomcat-8.5.15.tar.gz-c/usr/local/

Extract two tomcat, named Tomcat1 TOMCAT2

Because we're experimenting on the same machine, we're going to modify the second Tomcat HTTP and AJP ports to avoid port collisions. No longer described here.

Modify Server.xml following several places

<engine name= "Catalina" defaulthost= "localhost" jvmroute= "TOMCAT1" >

Here you add a tomcat1, as a route for the next mod JK Forwarding, and the other for TOMCAT2

Define the program site root directory here
<valveclassname= "Org.apache.catalina.valves.AccessLogValve" directory= "Logs" prefix= "Localhost_access_log." suffix= ". txt" pattern= "common" resolvehosts= "false"/>

 This defines the log and format
3.   Start Tomcat
sh/usr/local/tomcat1/bin/catalina.sh startsh/usr/local/tomcat2/bin/catalina.sh Start

Test two tomcat for normal access, return 200 to normal, and browse for tests. Test it according to the port you have changed.

Third,Configure Apache mod JK forwarding
1. Find LoadModule Add in httpd.conf
LoadModule Jk_module modules/mod_jk.so
Open and add the following two lines to open the configuration of Vhost and MOD_JK
Include Conf/extra/httpd-vhosts.confinclude conf/mod_jk.conf
2. Create mod_jk.conf in Apache's conf directory
#cat mod_jk.conf
jkworkersfileconf/workers.propertiesjklogfile/usr/local/apache/logs/jk.logjkshmfile/usr/local/apache/logs/ Jk-runtime-statusjkloglevelerrorjklogstampformat "[%d%h:%m:%s]" Jkoptions+forwardkeysize +ForwardURICompat- Forwarddirectoriesjkrequestlogformat "%w%V%u%q%s%T"
3. Create a Workers.properties file
# Cat Workers.properties
worker.list=controller,tomcat1,tomcat2 #  Tomcat1worker.tomcat1.port=8009worker.tomcat1.host=127.0.0.1worker.tomcat1.type=ajp13worker.tomcat1.lbfactor= 1worker.tomcat1.connection_pool_size=500worker.tomcat1.connection_pool_minsize=25worker.tomcat1.connection_ pool_timeout=300worker.tomcat1.socket_timeout=20 worker.tomcat2.port=8109worker.tomcat2.host= 127.0.0.1worker.tomcat2.type=ajp13worker.tomcat2.lbfactor=1worker.tomcat2.connection_pool_size= 500worker.tomcat2.connection_pool_minsize=25worker.tomcat2.connection_pool_timeout=300worker.tomcat2.socket_ Timeout=20 #========controllertomcat online =======worker.controller.type= lbworker.controller.balanced_workers=tomcat1,tomcat2worker.controller.sticky_session= 1worker.controller.connection_pool_size=1000worker.controller.connection_pool_minsize= 50worker.controller.connection_pool_timeout=300worker.controller.socket_timeout=20 
4, Configuration 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 &nbsP;       </directory></virtualhost> 
[[email protected] www]# LS1 2[[email protected] www]# ls *1:1.tt index.html2:1.tt index.html
/WWW/1 and/WWW/2 are the root directories of TOMCAT1 and TOMCAT2 respectively. The same file name is placed inside, but the content is different. Then refresh the browser to see if the content will change, and if it will succeed on the main TD forward.
Jkmount/*.html* Controller
This is the definition of all. HTML requests are forwarded to Tomcat processing, here is the experiment, production should be moving too much content sent to Tomcat processing, such as JSP.
