利用nginx搭建tomcat集群

一、安装tomcat

tomcat安装不做介绍,在每台服务器上都安装tomcat即可!

二、安装nginx

yum安装nginx

三、修改nginx的配置文件

yum安装后,nginx的配置文件在/etc/nginx下面

可以执行指令:

vim /etc/nginx/nginx.conf

修改为:

 
 user  nginx;
 worker_processes  1;
   
 error_log  /var/log/nginx/error.log warn;
 pid        /var/run/nginx.pid;

 events {
     worker_connections  1024;
 }
 
 
 http {
     include       /etc/nginx/mime.types;
     default_type  application/octet-stream;
 
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
 
     access_log  /var/log/nginx/access.log  main;
 
    sendfile        on;
    #tcp_nopush     on;
 
     keepalive_timeout  65;
 
    #gzip  on;

     include /etc/nginx/conf.d/*.conf;
         upstream 名字{
                 server  192.168.30.101:8080 weight=1;
                 server  192.168.30.102:8080 weight=3;
                 server  192.168.30.103:8080 weight=3;
         }
 
         server {
                 listen  监听端口号;
                 server_name     域名;
 
 
                 location / {
                         proxy_pass http://名字;
                         proxy_redirect default;
                 }
         }
 }

注意:upstream后面的名字要与proxy_pass的的名字对应起来。

之后在每台服务器上都启动tomcat,访问你的域名加端口号就实现nginx部署tomcat集群了!

外加一个启动tomcat时实时查看日志的指令

./startup.sh | tail -f ../logs/catalina.out
