使用Keepalived提高吞吐量

可以使用keepalived設定長連接配接, 減少連接配接的建立和關閉, 提高吞吐量

upstream tomcats {
  server 192.168.247.136:8001;
  server 192.168.247.136:8002;
  server 192.168.247.136:8003;
  # 保持32個長連接配接
  keepalive 32;
}
server{
  listen        80;
  server_name   www.tomcat.com;
  location / {
    proxy_pass  http://tomcats;
