events key 配置tomcat type files 準備 mys all quest

環境：
準備三臺機械： 兩臺安裝tomcat 一臺安裝nginx;
安裝步驟省略；
tomcat一臺的IP：http://192.168.195.132:8080
另一臺tomcat一臺的IP：http://192.168.195.133:8080
nginxIP:http://192.168.195.134
主要：
nginx的配置文件nginx.conf：
#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;


events {
worker_connections 1024;
}

另外一臺：
