微服务模式：服务启动时注册eureka3秒后自动注销

1.问题现象:安装NCC应用后，微服务治理-注册中心无数据，查看注册历史及注销历史发现，服务在注册3秒后，服务自动注销。

查看私有配置文件自己公有配置文件信息均正确

/usr/local/tomcat/webapps/ROOT/WEB-INF/home/ierp/bin/msconfig.properties       （私）

/usr/local/tomcat/webapps/ROOT/WEB-INF/home/ierp/bin/eureka.properties         （公）

/usr/local/tomcat/webapps/ROOT/WEB-INF/home/ierp/bin/msconfig-public.properties （公）

由于通过控制台查看容器日志显示信息有限，所以需要通过kubectl  logs –f查看容器日志：

先查看服务所对应的pod信息：

kubectl get pod -o wide -A|grep sidecar

在查看容器日志输出到22.log文件：

kubectl  logs –f test-sidecar-7bdd7768cd-mr2pt -n c87e2267-1001-4c70-bb2a-ab41f3b81aa3>22.log

在启动NCC应用时，通过如下过滤器时，reids连接异常，导致ESA Server stopped

2.解决方案:通过如上的ESA Server stopped堆栈发现服务在启动过程中，servers存在stop所以存在服务在注册中心3秒后自动注销。通过错误堆栈发现在过滤器处理redis时，redis配置错误从而导致server起不来，导致服务stop。

检查redis配置，修改正确后，服务注册正常。
