The Nginx+tomcat of high-performance Web services realizes the reverse agent of debt balance and static and dynamic separation

In the actual production, Tomcat server is generally not used alone in the project, the response to static resources Nginx performance is better, in addition, because Nginx is dedicated to reverse proxy server, it is easy to implement the Java request forwarded to the back end to the Tomcat container processing, And itself is used to handle static resources.

Usually the Tomcat front end is Nginx or Apache, the back end is Tomcat, also means that no matter what the front-end is the role of the agent to do the work, but note that if you do a reverse proxy based on Nginx, Forwarding requests to Tomcat is forwarded based on the HTTP protocol, but note that the Tomcat connector has HTTPAJP jk2 Jserv, and if the Nginx-based forwarding only supports HTTP forwarding; If Apache does proxy forwarding, Almost all common protocols are supported, but common connection types are the AJP protocol, because the AJP protocol works in binary mode, and the HTTP protocol works in text mode, so AJP is more efficient than HTTP , so it is very often possible to use Apache to deploy a tomcat front-end Web server.

The following schema deployment Nginx+tomcat implements the direction agent:

The reverse proxy system architecture is planned as follows:

Server role	Server IP
Nginx	ETH0:172.16.100.1/16 eth1:192.168.56.10/24
Tomcat1	Eth0:192.168.56.11/24
Tomcat2	Eth0:192.168.56.12/24
Statichost (Nginx)	Eth0:192.168.56.13/24

The configuration process is as follows:

Tomcat Service installation configuration:

(1) Installing the JDK

# rpm -ivh jdk-7u9-linux-x64.rpm --files generated after installation of JDK #  cd /usr/java/ ; lltotal 4lrwxrwxrwx  1 root root    16 sep 27 09:09 default -> /usr/java/latestdrwxr-xr-x 10 root  root 4096 sep 27 09:09 jdk1.7.0_09lrwxrwxrwx  1 root root    21 sep 27 09:09 latest -> /usr/java/jdk1.7.0_09--Configuring the JDK environment variable #  vim /etc/profile.d/java.shexport java_home=/usr/java/jdk1.7.0_09export path= $PATH: $JAVA _ home/bin--perform the # . /etc/profile.d/java.sh--test to make the environment variable effective:# java -versionjava version  "1.7.0_45"         --JDK version openjdk runtime environment  ( RHEL-2.4.3.3.EL6-X86_64 U45-B15) openjdk 64-bit server vm  (build 24.45-b08,  Mixed mode) 

(2) Install Tomcat

Configure the Nginx server process as follows:

--Configuration nginx.confhttp {    upstream tomcat {                 --Define a Load Balancer cluster          server 192.168.56.11:8080;        server  192.168.56.12:8080;    } server {    listen        80;    server_name  localhost;     location / {        root   /usr/share/ nginx/html;        index  index.jsp index.html  Index.htm;    }    location ~* \. (jsp|do) $ {        --definition of all dynamic content forwarding to back-end tomcat cluster          proxy_pass http://tomcat;&Nbsp;   }    location ~* \. (Ico|css|jpg|jpeg|gif|png|pdf|doc|rar|exe|zip) $ {  --define all static content forwarding to 192.168.56.13         proxy_pass http://192.168.56.13;    }       }}

The access tests are as follows:

Above we can see the JSP dynamic content, the static content has been forwarded to the 192.168.56.13 static content host. Next we configure the Statichost host, the following configuration:

--Installation configuration nginx--copy tomcat images to statichost host # SCP [email protected]:/usr/local/tomcat/webapps/root/*/usr/share/nginx/ Html

Test access is as follows:

The above is the NGINX+TOMCAT realization of debt balance reverse proxy and static and dynamic separation content
