Nginx+tomcat cluster
Tomcat service is a free and open source web application service, which is a lightweight application server, which is generally used in small and medium-sized networks. Tomcat usually runs separately as a Servlet and JSP container on the back end.
Environment deployment: a nginx server accepts requests on the periphery, and multiple tomcat servers process and publish web web pages, which can achieve web load balancing.
To install tomcat:
V install JDK deploy JAVA environment
# tar xzvf jdk-7u65-linux-x64.gz
# mv jdk1.7.0_65/ / usr/local/java
# vim / etc/profile.d/java.sh
Export JAVA_HOME=/usr/local/java
Export PATH=$PATH:$JAVA_HOME/bin
# source / etc/profile.d/java.sh
# java-version
V install and configure Tomcat service
# tar xzvf apache-tomcat-7.0.54.tar.gz
# mv apache-tomcat-7.0.54 / usr/local/tomcat
# / usr/local/tomcat/bin/startup.sh
# netstat-lnupt | grep: 8080
V build a web site based on JAVA
# mkdir-p / web/webapp1
# vim / web/webapp1/index.jsp
JSP test1 page
# vim / usr/local/tomcat/conf/server.xml
Add relevant parameters:
Manually specify the location of the web web page
V deploy nginx server
# yum-y install pcre-devel zlib-devel
# tar xzvf nginx-1.6.0.tar.gz
# cd nginx-1.6.0
# groupadd www
# useradd-g www www-s / bin/false
# / configure-- prefix=/usr/local/nginx-- user=www-- group=www-- with-file-aio-- with-http_stub_module-- with-http_gzip_static_module-- with-http_flv_module-- with-http_ssl_module
# make & & make install
V Editing the nginx configuration file specifies the location of the tomcat server. When users visit the nginx server, they actually visit the web page on the tomcat server.
# vim / usr/local/nginx/conf/nginx.conf
Add relevant parameters:
Upstream tomcat_server {
Server 1.1.1.130:8080 weight=1
Server 1.1.1.120:8080 weight=1
}
Server {
. Omit
Location / {
Root html
Index index.html index.htm
Proxy_pass http://tomcat_server;
}
}
V restart the nginx server
# / usr/local/sbin/nginx-s stop
# / usr/local/sbin/nginx
