nginx 配置tomcat 实现负载均衡
环境：准备三台机械： 两台安装tomcat 一台安装nginx;
安装步骤省略；
tomcat一台的IP：http://192.168.195.132:8080
另一台tomcat一台的IP：http://192.168.195.133:8080
nginxIP:http://192.168.195.134
主要：
nginx的配置文件nginx.conf：
#usernobody;
worker_processes1;
#error_loglogs/error.log;
#error_loglogs/error.lognotice;
#error_loglogs/error.loginfo;
#pid logs/nginx.pid;
events {
worker_connections1024;
}
http {
include mime.types;
default_typeapplication/octet-stream;
#log_formatmain'$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_loglogs/access.logmain;
sendfile on;
#tcp_nopush on;
#keepalive_timeout0;
keepalive_timeout65;
upstream myServer{

server 192.168.195.133:8080 weight=2;
}

}

# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504/50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80

分别启动两台tomat 访问路径如：
http://192.168.195.132:8080/examples/index.html
另外一台：
http://192.168.195.133:8080/examples/index.html
