nginx+tomcat负载均衡

<Connector port="30001" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="30043" />

1.nginx编译安装

./configure --prefix=/usr/local/nginx --with-pcre=../pcre-8.36#【--with-pcre=/usr/local/pcre不可以，/opt/pcre-8.36,是pcre加压后的路径】。

make

make install

启动后

[root@centos1 conf]# netstat -antpl|grep nginx

2.tomcat 的配置文件

修改两个tomcat的配置文件中三个端口号

vim /usr/local/TC7_A/conf/server.xml

修改shutdown端口号

<Server port="30005" shutdown="SHUTDOWN">

修改http端口号

<Connector port="30001" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="30043" />

修改ajp端口号

<Connector port="30009" protocol="AJP/1.3" redirectPort="30043" />
