nginx配置tomcat集群

显示nginx的核心配置

#user nobody;
worker_processes 1;

events {

   worker_connections 1024;    #并发连接数
}

http {
include mime.types;
default_type application/octet-stream;

sendfile on;

#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

#gzip on;   （1）下面是与tomcat集群配置的关键 配置了2个tomcat，分别工作在端口17080和18080
upstream localhost {
server 127.0.0.1:17080;     #还可以配置各自的分发权重 weight=1
server 127.0.0.1:18080;     

#ip_hash;    #表示以hash的方式选择tomat节点
}
server {
listen 18900;   #nginx的监听端口
server_name localhost;           # （2）server_name必须和upstream后面的标识符一致
#charset koi8-r;

#access_log logs/host.access.log main;

location / {
root html;
index index.html index.htm;

proxy_pass http://localhost;          #（3）启用反向代理

proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 100;
proxy_send_timeout 100;
proxy_read_timeout 100;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;

}

配置tomcat的要点：

修改server.xml中

（1）<Server port="18005" shutdown="SHUTDOWN">

（2）<Connector port="18080" protocol="HTTP/1.1"

connectionTimeout="20000"
redirectPort="8443" />

 （3）

<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector port="8109" protocol="AJP/1.3" redirectPort="8443" />
