环境准备

1、准备一台nginx服务器 ip192.168.1.133 端口81

安装过程：

＃首先安装依赖：
yum -y install gcc-c++ 
yum -y install pcre pcre-devel 
yum -y install zlib zlib-devel 
yum -y install openssl openssl—devel
#注意 ： 安装nginx必须使用 root 用户安装
#创建一个nginx目录
mkdir /usr/local/src/nginx
#进入到nginx目录
cd /usr/local/src/nginx
#下载或上传安装包
wget http://nginx.org/download/nginx.tar.gz 或 rz上传
#解压安装包
tar -xvf nginx.tar.gz
#进入到解压后的目录
cd nginx
# 下面 才开始正式安装
#把nginx安装到指定用户的目录
mkdir -p /ucenter/soft/nginx
#安装配置 prefix为安装目录 user为用户 group为 组
./configure --prefix=/ucenter/soft/nginx --user=ucenter --group=ucenter
#编译
make 
#安装
make install
#在linux系统中由于非root用户不能占用80端口，所以需要使普通用户以root身份启动nginx。 
cd /ucenter/soft/nginx/sbin
#把soft文件下所有的文件所属者修改为ucener -r 表示递归
chown ucenter:ucenter ./soft/ -r
#修改 ./nginx 的所属为root
chown root nginx
#让普通用户可以使用80端口，可以使用root权限启用nginx
chmod u+s nginx
#修改配置文件 在修改配置文件之前 ，要备份该文件
cd conf/
# 要注意nginx 的工作进程，一般根据cpu的核数去修改
vim nginx.conf
#关闭防火墙，打开80端口
service iptables stop
#启动nginx
./nginx
#重启nginx
./nginx -s reload
#关闭nginx
./nginx -s stop

准备一台tomcat服务器，先准备java环境，安装jdk步骤省略

然后分别安装3个tomcat 服务器ip地址：192.168.1.143，tomcat1 8080端口，tomcat2 8081端口，tomcat3 8082端口。

apache-tomcat-7.0.64/conf/server.xml配置文件修改这三个地方，这样端口就不会冲突

<server port="8005" shutdown="shutdown">
<connector port="8080" protocol="http/1.1"
connectiontimeout="20000"
redirectport="8443" />
<connector port="8009" protocol="ajp/1.3" redirectport="8443" />

登录后复制

修改tomcat root目录下index.jsp，分别增加每个tomcat的标识，以及在页面上显示session id
