Nginx总复习---7

Debian 6下配置Nginx+Tomcat负载均衡(支持Session共享)

<>一、配置环境。

<>1、<>²<>²<>²<>²<>²<>2、<>²<>²<>²<>²<>²<>二、在Srv76上安装Nginx。

<>1、使用如下命令安装编译Nginx所需软件包。

srv76:~# apt-get upgrade

srv76:~# apt-get install zlibc libpcre++-dev bzip2 autoconf automake g++ gcc \

make libssl-dev libpcre3-dev build-essential

<>2、使用如下命令下载并编译安装Nginx及nginx_upstream_jvm_route。

srv76:~# adduser --system --no-create-home --disabled-login \

--disabled-password --group nginx

srv76:~# cd /usr/src

srv76:src# wget http://nginx.org/download/nginx-1.0.4.tar.gz

srv76:src# svn checkout http://nginx-upstream-jvm-route.googlecode.com/svn/trunk/ nginx-upstream-jvm-route-read-only

srv76:src# tar -xvzf nginx-1.0.4.tar.gz

srv76:src# cd nginx-1.0.4

srv76:nginx-1.0.4# patch -p0 < ../nginx-upstream-jvm-route-read-only/jvm_route.patch

srv76:nginx-1.0.4# ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx \

--with-http_stub_status_module --with-http_ssl_module \

--with-pcre --add-module=../nginx-upstream-jvm-route-read-only

srv76:nginx-1.0.4# make && make install

<>3、使用如下命令配置Nginx服务启动命令。

srv76:~# chmod +x /etc/init.d/nginx

srv76:~# /usr/sbin/update-rc.d -f nginx defaults

srv76:~# ln -s /usr/local/nginx/sbin/* /sbin/

srv76:~# mkdir /var/log/nginx

srv76:~# chgrp nginx /var/log/nginx/

srv76:~# chmod g+w /var/log/nginx/

<>三、安装及配置Tomcat及Java。

<>1、在Srv76、Srv77上使用如下命令安装Tomcat及Java。

srv76:~# apt-get install libmysql-java tomcat6 libservlet2.5-java libtomcat6-java \

mysql-server sun-java6-jdk sun-java6-bin tomcat6-admin \

sun-java6-jre

<>2、在Srv76将/etc/tomcat6/server.xml文件中“<Engine name="Catalina" defaultHost="localhost">”修改为如下内容。

<>3、在Srv77将/etc/tomcat6/server.xml文件中“<Engine name="Catalina" defaultHost="localhost">”修改为如下内容。

<>4、在Srv76、Srv77上使用如下命令重新启动Tomcat。

srv76:~# /etc/init.d/tomcat6 restart

<>四、修改/usr/local/nginx/conf/nginx.conf文件如下内容。
