環境準備
1、準備一臺nginx服務器 ip192.168.1.133 端口81
安裝過程：
＃首先安裝依賴：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 ： 安裝nginx必須使用 root 用戶安裝#創建一個nginx目錄mkdir /usr/local/src/nginx#進入到nginx目錄cd /usr/local/src/nginx#下載或上傳安裝包wget http://nginx.org/download/nginx.tar.gz 或 rz上傳#解壓安裝包tar -xvf nginx.tar.gz#進入到解壓后的目錄cd nginx# 下面 才開始正式安裝#把nginx安裝到指定用戶的目錄mkdir -p /ucenter/soft/nginx#安裝配置 prefix為安裝目錄 user為用戶 group為 組./configure --prefix=/ucenter/soft/nginx --user=ucenter --group=ucenter#編譯make #安裝make install#在linux系統中由于非root用戶不能占用80端口，所以需要使普通用戶以root身份啟動nginx。 cd /ucenter/soft/nginx/sbin#把soft文件下所有的文件所屬者修改為ucener -R 表示遞歸chown ucenter:ucenter ./soft/ -R#修改 ./nginx 的所屬為rootchown root nginx#讓普通用戶可以使用80端口，可以使用root權限啟用nginxchmod u+s nginx#修改配置文件 在修改配置文件之前 ，要備份該文件cd conf/# 要注意nginx 的工作進程，一般根據cpu的核數去修改vim nginx.conf#關閉防火墻，打開80端口service iptables stop#啟動nginx./nginx#重啟nginx./nginx -s reload#關閉nginx./nginx -s stop
準備一臺tomcat服務器，先準備java環境，安裝jdk步驟省略
然后分別安裝3個tomcat 服務器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配置文件修改這三個地方，這樣端口就不會沖突
<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" />
修改tomcat ROOT目錄下index.jsp，分別增加每個tomcat的標識，以及在頁面上顯示session ID
