nginx+tomcat实现反向代理的负载均衡

安装java环境

server12:

[root@server12 ~]# sh jdk-6u32-linux-x64.bin
[root@server12 ~]# mv jdk1.6.0_32/ /usr/local/
[root@server12 ~]# cd /usr/local/
[root@server12 local]# mv jdk1.6.0_32/ java
[root@server12 local]# which java
/usr/local/java/bin/java

配置java环境变量

vim /etc/profile

export JAVA_HOME=/usr/local/java  
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib  
export PATH=$PATH:$JAVA_HOME/bin

. /etc/profile

检验：

编写java测试页，看是否jdk是否配置成功

vim test.java

class test {
        public static void main(String[] args)
        {
                System.out.println("hello world!");
        }
}

编译和执行

[root@server12 ~]# javac test.java 
[root@server12 ~]# java test
hello world!

配置tomcat环境

[root@server12 ~]# tar zxf apache-tomcat-7.0.37.tar.gz -C /usr/local/
[root@server12 ~]# cd /usr/local/
[root@server12 local]# ln -s apache-tomcat-7.0.37/ tomcat
[root@server12 local]# cd tomcat/
[root@server12 tomcat]# cd bin/
[root@server12 bin]# ./startup.sh

netstat -antlpue

tcp        0      0 :::8080                     :::*                        LISTEN      0          20026      1718/java

tomcat页面

nginx+tomat*2开始负载均衡拉～～

server11:

cd /usr/local/nginx/conf/

vim nginx.conf

 22 http {
 23     include       mime.types;
 24     default_type  application/octet-stream;
 25 
 26         upstream miao{
 27         server  172.25.88.12:8080;    
 28         server  172.25.88.13:8080;
 29         }






 69         location ~ \.jsp$ {
 70                 proxy_pass http://miao;

nginx -s reload

server12:

cd /usr/local/ 

scp -r tomcat/ java/ 172.25.4.13:/usr/local/

cd /usr/local/tomcat/webapps/ROOT 

vim test.jsp

server2 the time is: <%=new java.util.Date() %>

cd /usr/local/tomcat/bin/ ./startup.sh

server13:

cd /usr/local/tomcat/webapps/ROOT 

vim test.jsp

server3 the time is: <%=new java.util.Date() %>

vim /etc/profile

export JAVA_HOME=/usr/local/java
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin

cd /usr/local/tomcat/bin/ ./startup.sh
