Nginx加多个tomcat实现负载均衡，动静分离

1.主机

centos6.4 IP:10.10.54.157

2.在此主机上安装nginx，及两个tomcat，nginx的反向代理功能可以把用户请求负载到tomcat上

nginx使用80端口，两个tomcat分别使用8080，9080端口

目的：当访问10.10.54.157这台服务器时，静态页面由nginx处理，动态页面由tomcat处理

3.软件下载

wget http://nginx.org/download/nginx-1.4.5.tar.gz

wget http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-x64.rpm#jdk提供tomcat运行环境

wget http://apache.dataguru.cn/tomcat/tomcat-7/v7.0.52/bin/apache-tomcat-7.0.52.tar.gz

#nginx使用fpm的方式调用php

#php5.4以后版本中已经支持php-fpm,所以只需要在php编译参数里指定--enable-fpm即可

1.编译安装

shell> yum -yinstallzlib-devel pcre-devel openssl-devel#nginx依赖包

shell>tarxvf nginx-1.4.5.tar.gz

shell>cdnginx-1.4.5

shell> ./configure--prefix=/usr/local/nginx--with-pcre --with-http_stub_status_module --user=apache --group=apache --with-http_ssl_module --with-http_gzip_static_module

shell>make&&makeinstall

2.启动nginx

shell>/usr/local/nginx/sbin/nginx-c/usr/local/nginx/conf/nginx.conf

##添加nginx支持php

3.首先为php创建配置文件

shell>cpphp.ini-production/usr/local/php/php.ini

shell>mv/usr/local/php/etc/php-fpm.conf.default/usr/local/php/etc/php-fpm.conf

shell>ln-s/usr/local/php/bin/php/usr/bin/

4.配置php-fpm.conf

shell>vi/usr/local/php/etc/php-fpm.conf

--------------------------------

listen =/var/run/php-fpm.sock# 使用unix socket

--------------------------------

5.启动php-fpm

shell>/usr/local/php/sbin/php-fpm

shell> rpm -ivh jdk-7u51-linux-x64.rpm

shell>vi/etc/profile

-----------------------

exportJAVA_HOME="/usr/java/jdk1.7.0_51"

exportCLASSPATH="$JAVA_HOME/lib:$JAVA_HOME/jre/lib"

exportPATH="$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$HOME/bin"

CATALINA_HOME="/usr/local/tomcat"

-----------------------

shell>source/etc/profile

shell> java -version#显示版本说明成功

java version"1.7.0_45"

1.解压

shell>tarxvf apache-tomcat-7.0.52.tar.gz

shell>cpapache-tomcat-7.0.52/usr/local/tomcat1

shell>cpapache-tomcat-7.0.52/usr/local/tomcat2

shell>chownapache.apache/usr/local/tomcat1

shell>chownapache.apache/usr/local/tomcat2

【tomcat1 and tomcat2】

2.制作tomcat启动脚本

shell>cpcatalina.sh/etc/init.d/tomcat1

shell>chmod+x/etc/init.d/tomcat1

shell> vim/etc/init.d/tomcat1

shell> chkconfig --add tomcat1

【tomcat1 and tomcat2】

3.tomcat配置用户管理(可以不设置)

shell>cd/usr/local/tomcat1/conf

shell> vim tomcat-users.xml

-----------------------------------------

<role rolename="manager-gui"/>

<role rolename="admin-gui"/>

<user username="tomcat"password="tomcat"roles="admin-gui,manager-gui"/>

#用户名和密码都为tomcat

-----------------------------------------

【tomcat1 and tomcat2】

4.重启tomcat

shell>/etc/init.d/tomcatstop

shell>/etc/init.d/tomcatstart

shell> vim/usr/local/nginx/conf/nginx.conf

--------------------------------------------------------
