After multiple tomcat servers are used for load balancing, the tomcat port is not open to the public, so the tomcat server Load balancer can be accessed precisely.
Background:
Use Nginx and two
with Apache + mod_jk + Tomcat to achieve Tomcat The load balancing of the clusterIf there is a problem, you can use the CMD CD in the Apache installation file under the bin, run the httpd file, the error message will be printed out.The problem I have here is that the Include conf/mod_jk.conf cannot
: This article mainly introduces how to precisely access tomcat when the tomcat port is not open to the outside when multiple tomcat servers are used for load balancing, if you are interested in the PHP Tutorial, refer.
Background:
Use Nginx and two
Background:
Load balancing was implemented with Nginx and two Tomcat, and Tomcat ports (8080 and 8090) were closed in the firewall, and only 80 ports were opened externally. The Nginx configuration is as follows:
Upstream Tomcatcluster {
Server
: 8080;
Server
: 8090;
}

properties. The contents of the document are as follows:
[Root@node1 bin]# Vim/etc/httpd/extra/workers.properties
Worker.list = TOMCAT1,STAT1
Worker.tomcat1.type = ajp13
Worker.tomcat1.host = 192.168.0.1
Worker.tomcat1.port = 8009
Worker.tomcat1.lbfactor=1
Worker.stat1.type = Status
Restart the HTTPD service and test
[Root@node1 bin]# Service httpd restart
The test page is as follows
With the above configuration and testing, now that Apache is implemented based on Mod
On an article to tell you the installation of Nginx, then this article for you to talk about Nginx+tomcat to achieve load balance.
First of all, why use Ngnix to do load balancing, in fact, the most famous for the load balance is F5, F5 is in the hardware facilities, often t
hardware devices, sizes and services provided by multiple server groups, we can consider using the most appropriate load balancing method for each server group, Then again, load-balanced or clustered across the multiple server clusters to provide services to the outside world (that is, to treat these multiple server groups as a new server farm) for optimal perfo
A few days ago in the Apache implementation of multi-tomcat load Balancing cluster through JK, the reference network configuration to configure the configuration file, access to the existing tomcat in the JSP file found that the Apache prompt URL does not exist, and then check the configuration file and the
Some days before doing Apache through JK to achieve a multi-tomcat load Balancing cluster, the reference network configuration after configuring the profile, access to the existing Tomcat file in the Apache hint URL does not exist, and then check the configuration file and Tomcat
In the course of doing the experiment, a phenomenon was found:
Both A and B are working properly.
User C made two requests Q1 and Q2,Q1 request was processed by a, Q2 request was processed by B
A stopped, c initiated the request Q3, was handled by B normally,
A restart Startup
C Initiate request Q4,q5, ... These requests are handled by B
User D initiates a request to be processed by a
After that, the C's request can be processed by a and B normally.
I found some informa

CentOS Apache-based Tomcat load balancing and clustering First, the background principle1, Tomcat to do a Web server has its limitations, low processing power, low efficiency. withstands concurrency Small (around 1000). However, there are many websites or pages that are JSP. And the use of
Apache.This article is mainly about Nginx + Tomcat reverse proxy and load balancing deployment, to popular and practical-oriented. This article does not have much to do with each section and can be studied separately according to the requirements.Come down and look at the process of Nginx reverse proxy:Nginx Load
Nginx is a server software that is also a high-performance HTTP and reverse proxy server, as well as a proxy mail server. In other words, we can publish the website on the Nginx, can realize the load balance (enhances the reply efficiency, avoids the server crashes), but also can realize the function as the mail server to send and receive the mail. And the most common is to use Nginx to achieve load
In order to achieve server upgrades without affecting user use, it is necessary to configure two tomcat on one or more servers. The following procedure describes configuring two tomcat on the same server. The steps are as follows: 1, copy the original tomcat to another directory, such as: tomcat-8090, clear Logs Direct
