企业-LNMP-实现tomcat的负载均衡

实现tomcat的负载均衡

server1：

cd /usr/local/openresty/nginx/

vim conf/nginx.conf					配置负载均衡
http {
        upstream tomcat {
        server 172.25.38.1:8080;	后端服务器1
        server 172.25.38.2:8080;	后端服务器2
        }

	location ~ \.jsp$ {
               proxy_pass      http://tomcat;	访问tomcat
       }

#       location /memc {			将memcache设定全部注释
#       internal;
#       memc_connect_timeout 100ms;
#       memc_send_timeout 100ms;
#       memc_read_timeout 100ms;
#       set $memc_key $query_string;
#       set $memc_exptime 300;
#       memc_pass memcache;
#       }

/usr/local/openresty/nginx/sbin/nginx -t
/usr/local/openresty/nginx/sbin/nginx -s reload

cd /usr/local/tomcat/webapps/ROOT/
vim index.jsp	这个比较复杂，从网上下载一个

tomcat的重启只能先关闭先开启

./shutdown.sh
./startup.sh

server2：

tar zxf apache-tomcat-7.0.37.tar.gz -C /usr/local
tar zxf jdk-7u79-linux-x64.tar.gz -C /usr/local
cd /usr/local
ln -s apache-tomcat-7.0.37 tomcat

vim /etc/profile
export JAVA_HOME=/usr/local/jdk1.7.0_79
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin

source /etc/profile
java -version
cd /usr/local/tomcat/webapps/ROOT/
mv index.jsp index.jsp.bak

将server1的index.jsp传给server2

cd /usr/local/tomcat/bin/
./startup.sh 
netstat -tnalp

因为index.jsp我们是从网上下载的，还是保持文件的原名
