官网文档2.X

Kubernetes Nacos

Nacos镜像： nacos/nacos-server:latest

我按照官方文档执行到

• 验证Nacos节点启动成功

 然后pods一直重启,查看pod日志

 

这个参数怎么会少呢？

启动pod的Yaml文件

尝试修改配置文件增加环境变量env:

-name: NACOS_AUTH_IDENTITY_KEY

  value: serverIdentity

但是依然无效

上面参数官方文档上有相关描述

Nacos Docker 快速开始

 尝试切换nacos镜像版本：v2.2.0   docker pull nacos/nacos-server:v2.2.0

然后在启动就这样了

第一种情况（没有执行sql初始化语句）的解决办法：

https://github.com/nacos-group/nacos-k8s/issues/205

在GitHub上找到了答案，感谢这位大佬

在前面的流程中，看到了这个sql的初始化语言，由于当时打开链接404就没有管了

这个文件已经不再这个地方了  

 nacos-k8s/nacos-mysql.sql at master · nacos-group/nacos-k8s · GitHubzz

执行SQL完成后，启动终于成功了！ 

 没有重启次数了

第二种（nacos-pvc-nfs.yaml配置的mysql service地址变更了）情况的解决办法：

原因：在nacos-pvc-nfs.yaml 文件中的mysql.host: "10.102.179.83" (msyql service地址)变更了，导致nacos启动时找不到数据库

修改mysql service 地址
