下載軟件：
wget http://www.minunix.com/docs/web/openssl-1.0.1c.tar.gz Wget http://www.minunix.com/docs/web/pcre-8.31.tar.gz wget http://www.minunix.com/docs/web/zlib-1.2.7.tar.gz wget http://www.minunix.com/docs/web/nginx-1.2.8.tar.gz wget http://nginx-upstream-jvm-route.googlecode.com/files/nginx-upstream-jvm-route-0.1.tar.gz
環境安裝：
tar xf openssl-1.0.1c.tar.gz && tar xf pcre-8.31.tar.gz && tar xf zlib-1.2.7.tar.gz tar xf nginx-upstream-jvm-route-0.1.tar.gz
JDK安裝就略過了 只需要下載安裝然後在/etc/profile添加路徑就行了
export JAVA_HOME=/usr/java/jdk1.7.0_09 export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin
安裝nginx
tar xf nginx-upstream-jvm-route-0.1.tar.gz tar zxvf nginx-1.2.8.tar.gz cd nginx patch -p0 < ../nginx-upstream-jvm-route/jvm_route.patch ##這一步很重要 不執行的話後面的nginx。conf配置會報錯jvm錯誤 ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_gzip_static_module --with-http_stub_status_module --with-select_module --with-poll_module --with-http_sub_module --with-http_ssl_module --with-md5=/usr/lib64 --with-sha1=/usr/lib64 --pid-path=/usr/local/nginx/var/run/nginx.pid --with-pcre=/usr/local/soft/pcre-8.21 --with-zlib=/usr/local/soft/zlib-1.2.7 --with-openssl=/usr/local/soft/openssl-1.0.1d --add-module=/usr/local/soft/nginx_upstream_jvm_route/ make && make install
##到此支持jvm-route模塊的nginx安裝完畢 下面是配置文件nginx.conf

}安裝tomcat 下載apache-tomcat 在/usr/local中有tomcat1 tomcat2
tomcat1修改
<Engine name="Catalina" defaultHost="localhost" >增加jvmRoute="tomcat1"
tomcat2修改
<Engine name="Catalina" defaultHost="localhost" >增加jvmRoute="tomcat2" 並且需要把原來默認的8080 8005 8009改成其他的端口我就改成9080 9005 9009
開始測試
tomcat1測試文件
vim /usr/local/tomcat1/webapps/aa/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
%>
<html>
<head>
</head>
<body>
888888
<br />
<%out.print(request.getSession()) ;%>
<!--輸出session-->
<br />
<%out.println(request.getHeader("Cookie")); %>
<!--輸出Cookie-->
</body>
</html>tomcat2測試文件
vim /usr/local/tomcat2/webapps/aa/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
%>
<html>
<head>
</head>
<body>
9999999
<br />
<%out.print(request.getSession()) ;%>
<!--輸出session-->
<br />
<%out.println(request.getHeader("Cookie")); %>
<!--輸出Cookie-->
</body>
</html>啓動nginx和tomcat之後訪問http://192.168.43.139/aa/會發現tomcat1和tomcat2不斷在切換 這一步說明負載成功。那麼現在實現session。
修改nginx.conf將上面upstream一段修改爲如下
upstream minunix.com {
server 192.168.0.4:8080 srun_id=tomcat1; ##不增加srun_id就會不斷兩個頁面訪問增加之後就實現了session
server 192.168.0.52:8080 srun_id=tomcat2; ##
ip_hash;
jvm_route $cookie_JSESSIONID|sessionid reverse;
}重啓nginx
現在訪問頁面會不斷出現8888 或者99999 在一個頁面不會變 停止某個tomcat就會顯示另外一個
