藍鯨-監控 排錯思路 - 原理push - bkdata報錯 - saas的日志

1.現象和報錯

1.[10.253.124.21] paas_agent()    paas_agent                       FATAL     Exited too quickly (process log may have details)

2.看paas_agent的日志
: no such host]
2019/06/06 14:09:41 http.go:183: 證書驗證失敗:Post https://license.service.consul:8443/certificate: dial tcp: lookup license.service.consul on 61.144.227.5:53: no such host

2.思路和解決方法

3.由報錯聯想到之前有重啟網絡
所以dns變成原來配置的
 vim /etc/resolv.conf 
nameserver 127.0.0.1

 3.當無法解析時，第一步，在報錯的機器上使用dig看看consul能否解析：

dig xxx.service.consul @127.0.0.1
./bkcec stop consul
ps aux|grep consul
kill -9 pid
