nginx 健康检查配置
（1）upstream配置
check interval=1000 rise=2 fall=5 timeout=10000 type=http port=6002;
check_http_send "GET /info HTTP/1.0\r\n\r\n"; #注意这里检查可达的URL
check_http_expect_alive http_2xx http_3xx;
（2）location 配置
proxy_connect_timeout 90;
proxy_send_timeout 300;
proxy_read_timeout 300;
（3）生效日志
/logs/error.log 如果出现不可达该日志一直检测！
