Nginx + Tomcat dynamic/static separation and Nginx optimization (Enterprise case)

Objective: nginx processes static pages of user requests. tomcat processes jsp pages of user requests to achieve dynamic separation. nginx processes static pages more efficiently than tomcat, which improves concurrency, processing performance.
Prepare software:
Download jdk1.7: http://www.Oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
Download tomcat8.0: http://tomcat.apache.org/download-80.cgi
Download nginx1.4.4: http://nginx.org/en/download.html
1. JDK Configuration
[Root @ localhost ~] # Tar xvfjdk-7u45-linux-x64.tar.gz
[Root @ localhost ~] # Mv jdk1.7.0 _ 45 // usr/local/jdk
[Root @ localhost ~] # Vi/etc/profile
JAVA_HOME =/usr/local/jdk
PATH = $ PATH: $ JAVA_HOME/bin
CLASSPATH =.: $ JAVA_HOME/lib: $ JAVA_HOME/jre/lib
Export JAVA_HOME PATHCLASSPATH
[Root @ localhost ~] # Source/etc/profile
[Root @ localhost ~] # Java-version # The version description is displayed successfully.
Java version "1.7.0 _ 45"

2. Tomcat configuration

[Root @ localhost ~] # Tar zxvfapache-tomcat-8.0.0-RC5.tar.gz
[Root @ localhost ~] # Music apache-tomcat-8.0.0-RC5/usr/local/tomcat

# Tomcat runs as root by default, which is not secure. We set it to use a common user.

[Root @ localhost ~] # Groupadd tomcat
[Root @ localhost ~] # Useradd-g tomcat
[Root @ localhost ~] # Passwd tomcat
[Root @ localhost ~] # Chown tomcat. tomcat-R/usr/local/tomcat
[Root @ localhost ~] # Su-tomcat/usr/local/tomcat/bin/startup. sh
[Root @ localhost ~] # Echo "su-tomcat/usr/local/tomcat/bin/startup. sh">/etc/rc. local # Start upon startup

3. install and configure Nginx

[Root @ localhost ~] # Groupaddnginx
[Root @ localhost ~] # Useradd-gnginx-s/sbin/nologin nginx
[Root @ localhost ~] # Yuminstall-y make zlib-devel openssl-devel pcre-devel

[Root @ localhost ~] # Cdnginx-1.4.4
[Root @ localhost nginx-1.4.4] #./configure -- prefix =/usr/local/nginx -- with-http_ssl_module -- with-http_gzip_static_module -- with-http_stub_status_module
[Root @ localhost nginx-1.4.4] # make & make install

# Master configuration file configuration
