Nginx+Tomcat dynamic and static separation architecture

Nginx+tomcat is the current mainstream java web architecture, Nginx dynamic and static separation is simply to separate dynamic and static requests, can not be understood as simply the physical separation of dynamic pages and static pages. Strictly speaking, dynamic requests should be separated from static requests, which can be understood as using Nginx to deal with static pages, Tomcat and Resin to come out dynamic pages.

From the current implementation point of view, dynamic and static separation can be roughly divided into two types: one is simply to separate static files into separate domain names and put them on separate servers, which is also a popular solution at present; another method is to release dynamic and static files together and separate them through nginx.

Nginx server

1. Preparation of installation environment

Operating system version

Kernel version

Virtual machine IP address

CentOS 7.0

3.10.0-229.el7.x86_64

192.168.137.128

2. Install dependency package install gcc,gcc-c++,automake

Yum-y install gcc gcc-c++ automake

Install pcre,pcre-devel

To support the functionality of rewrite, you need to install pcre

Yum-y install pcre pcre-devel

Install openssl,openssl-devel

Support for ssl functionality

Yum-y install openssl openssl-devel

Install zlib, zlib-devel

Support for gzip compression

Yum-y install zlib zlib-devel

3. Source code compilation and installation

The official stable version of nginx-1.8.1 selected for this installation

1. Create nginx system users

[root@bogon ~] # useradd-r nginx

[root@bogon ~] # id nginx

Uid=997 (nginx) gid=995 (nginx) groups=995 (nginx)

[root@bogon local] # cd / usr/local/src/

[root@bogon src] # rz

[root@bogon src] # ls

Nginx-1.8.1.tar.gz

[root@bogon src] # tar-xzvf nginx-1.8.1.tar.gz

[root@bogon src] # cd nginx-1.8.1

[root@bogon nginx-1.8.1] # / configure-- prefix=/usr/local/nginx-- with-http_ssl_module-- with-http_stub_status_module

[root@bogon nginx-1.8.1] # make & & make install

After installation, start the service with / usr/local/nginx/sbin/nginx and then visit to see the test page.

JDK,tomcat installation (tomcat server)

Download the software by yourself

[root@bogon src] # tar-xf jdk-8u73-linux-x64+%281%29_.gz

[root@bogon src] # mv jdk1.8.0_73/ / usr/java/

[root@bogon src] # vi/etc/profile finally adds the following paragraph

ExportJAVA_HOME=/usr/java/jdk1.8.0_73

ExportCLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

ExportPATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOMR/bin

[root@bogon src] # source/etc/profile to make it effective

Test Java

Deploy Tomcat

[root@bogon src] # tar-xzvf apache-tomcat-7.0.63.tar.gz

[root@bogon src] # cp apache-tomcat-7.0.63 / usr/local/tomcat1-a

[root@bogon src] # cp apache-tomcat-7.0.63 / usr/local/tomcat2-a

The TOMCAT profile server.xml modifies the tomcat port respectively:

Shutdown port: 8005 is mainly responsible for starting and shutting down.

Ajp port: 8009 is mainly responsible for equalization through ajp (commonly used for apache and tomcat integration)

Http port: 8080 can be accessed directly through the web page (nginx+tomcata integration)

Tomcat1: default port

Tomcat2: 8006 8010 8081 respectively

[root@bogonsrc] # vi / usr/local/tomcat2/conf/server.xml

Start tomcat

[root@bogon src] # / usr/local/tomcat1/bin/startup.sh

[root@bogon src] # / usr/local/tomcat2/bin/startup.sh

Ps-ef | grep tomcat can view services and start them

Netstat-ntulp | grep java can view the port on which the service is started

Client access:

Http://192.168.137.128:8080/

Http://192.168.137.128:8081/

You can see the test page of tomcat

If you need to modify the directory defined for yourself by the tomcat publishing directory, you need to make the following adjustments to create two publishing directories:

Mkdir-p / data/webapps/ {www1,www2}

Edit vi/usr/local/tomcat1/conf/server.xml to add content to the last line before.

Edit vi/usr/local/tomcat2/conf/server.xml to add content to the last line before.

Tomcat1 publishes the contents of the directory: index.jsp

123456TOMCAT_1 JSP Test Page

Tomcat2 publishes the contents of the directory: index.jsp

123456TOMCAT_2 JSP Test Page then restarts the service through IP plus port access test, which can be accessed normally.

Test the nginx profile

[root@bogon ~] # / usr/local/nginx/sbin/nginx-t

Nginx: the configuration file/usr/local/nginx/conf/nginx.conf syntax is ok

Nginx: configuration file/usr/local/nginx/conf/nginx.conf test is successful

Smooth restart

/ usr/local/nginx/sbin/nginx-s reload

The test can check the balance success through http://192.168.137.128/ access, and the static and dynamic separation test is also successful.

Be careful

Smooth restart error report, there are two solutions for your reference

[root@bogon conf] # / usr/local/nginx/sbin/nginx-s reload

Nginx: [error] invalid PID number "" in "/ usr/local/nginx/nginx.pid"

Solution one

Sudo nginx-c/usr/local/etc/nginx/nginx.conf

Sudo nginx-s reload

Solution two

[root@bogon ~] # vi/usr/local/nginx/conf/nginx.conf

Note pid, just save and restart.

Debug log path Nginx

[root@bogon] # tail-f / usr/local/nginx/logs/
