Installing modjk on apache httpd in Cent. OS 6. x7. x Food Concerns. Cent. OS again. Today Im going to show you how to install and configure modjk in apache httpd using a server with Cent. OS. Currently this tutorial was tested on Centos 6. Introduction. So, whats modjkIn simple words, modjk allows us to connect an instance of tomcat with the apache httpd web server. This is useful for example if you have your httpd serving different kind of webapps php, Ro. R, etc and you want to publish a java app running on a tomcat instance. In this case, httpd run in port 8. In this case, the httpd server is giving us access to for example an internal network where your tomcat instances live. See the next diagram for a visual explanation Why not use modproxy This is indeed a good question. From a stackoverflow questionanswer modproxy Pros. No need for a separate module compilation and maintenance. Apache 2. 2 distribution. Ability to use httphttps or AJP protocols, even with the same balancer. Cons. modproxyajp does not support larke 8k packet sizes. Basic load balancer. Does not support Domain model clustering. Pros. Advanced load balancer. Advanced node failure detection. Support for large AJP packet sizes. Cons. Need to build and mantain a separate module. So, the discussion is there, no final answer. A good article covering this topic is Deciding between modjk, modproxyhttp and modproxyajp from Tomcat Experts. Installation. The installation process for modjk is really simple but were going to need to compile the module first. Before doing any compile work, ensure you have both httpd and tomcat installed. Now. yum install httpd devel apr apr devel apr util apr util devel gcc gcc c make autoconf libtool. Now, go to the official modjk website and download the latest version http tomcat. In the native folder check the last step in the code above were going to configure make make install the connector. UPDATE May 1. 6, 2. The user Matthew Herzog in the comments pointed me that apxs has moved to usrbinapxs as opposed to usrsbinapxs. In my system I still have apxs on usrsbin but if you run into troubles doing the previous steps maybe this can help. UPDATE May 1. 6, 2. The user Akash Hikadi reported on the comments that to make the previous command to work he had to add the flag enable api compatibility. If you get the next error when doing the previous steps No targets specified and no makefile found or No rule to make target install try running. If all goes well youre going to have the modjk. Configuration. First, lets enable the AJP connection on your tomcat server, in your server. TOMCATHOMEconfserver.

Great article on securing your Apache server and web apps Along with using a web application firewall, its a good idea to use a network firewall like HeatShield. Apache Tomcat 7. 0. TomcatWeb. In this post, i will share on how to install GUI for network configuration on CentOS 6. The mentioned network GUI tools will edit the system configuration files. TOMCATHOMEconfserver. Add under the lt Service nameCatalina tag. Define an AJP 1. 3 Connector on port 8. Connector port8. Configure the Apache source tree for the Linux platform and customize it to suit the pattern requirements. This is done using the script Configure located in the root. AJP1. 3 redirect. Port8. 44. 3 lt Define an AJP 1. Connector on port 8. Connectorport8. AJP1. Cracking Sound In Knee When Squatting My Knee. Port8. 44. 3 And modify the Engine tag so its looks like. Engine nameCatalina default. Hostlocalhost jvm. Routejvm. 1 1lt Engine nameCatalinadefault. Hostlocalhostjvm. Routejvm. 1 Observation 1 for each tomcat instance linked to your httpd server, you need to define a different jvm. Route parameter. For example, for a second instance you could use. Engine nameCatalina default. Hostlocalhost jvm. Routejvm. 2 1lt Engine nameCatalinadefault. Hostlocalhostjvm. Routejvm. 2 Now, lets go with the httpd configuration. First, create a modjk. And populate the file with the following. Load. Module jkmodule etchttpdmodulesmodjk. Jk. Workers. File etchttpdconfworkers. Where to put jk shared memory. Jk. Shm. File varrunhttpdmodjk. Where to put jk logs. Jk. Log. File varloghttpdmodjk. Set the jk log level debugerrorinfo. Jk. Log. Level info. Select the timestamp log format. Jk. Log. Stamp. Format a b d H M S Y. Jk. Request.

Workers. File property on modjk. With the next content. Worker. worker. stat. Worker. typeajp. Worker. Worker. port8. 00. Workerworker. stat. Worker. typeajp. Worker. Worker. port8. 00. For every app server from tomcat to httpd youre going to have a specific worker. Dont forget to define the worker first in the worker. For example, lets assume were going to add another app from tomcat. Worker,app. 2Worker. Worker. typeajp. Worker. Worker. port8. 00. Worker. typeajp. Worker. Worker. port8. 00. Worker,app. 2Workerworker. Worker. typeajp. Worker. Worker. port8. 00. Worker. typeajp. Worker. Worker. port8. 00. Well, everything looks good now. The final step is to configure the Virtual. Host for every app on httpd. Its a good practice to maintain your Virtual. Hosts in separated files. Now, in your recently created app. Virtual. Host 8. Server. Name app. Server. Admin adminmyhost.

Host for your second app use the app. Worker configured previously and so on for other apps. Final steps and conclusion. If you followed all the previous steps, you should be able to interact with your tomcat app directly from http app. Beautiful In this tutorial, we learned how to use modjk to connect different tomcat instances with the httpd web server. The procedure is straighforward but involves some compile tasks and a few configurations on each server. If you have any dobts dont hesitate to initiate a converstion in the comments sections.
