蓝鲸-监控 排错思路

1.现象和报错

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: 证书验证失败:Post https://license.service.consul:8443/certificate: dial tcp: lookup license.service.consul on 61.144.227.5:53: no such host

2.思路和解决方法

3.由报错联想到之前有重启网络
所以dns变成原来配置的
 vim /etc/resolv.conf 
nameserver 127.0.0.1

 3.当无法解析时，第一步，在报错的机器上使用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
