1. nacos 账号密码登录，默认未开启验证权限，不登录也能访问nacos控制台配置文件,生产环境非常不安全。所以需要手动开启安全认证。
2. 本地启动nacos的 application.properties配置文件更改如下：

   ### The auth system to use, currently only 'nacos' and 'ldap' is supported:
   nacos.core.auth.system.type=nacos### If turn on auth system:
   nacos.core.auth.enabled=true### Turn on/off caching of auth information. By turning on this switch, the update of auth information would have a 15 seconds delay.
   nacos.core.auth.caching.enabled=true### Since 1.4.1, Turn on/off white auth for user-agent: nacos-server, only for upgrade from old version.
   nacos.core.auth.enable.userAgentAuthWhite=false### Since 1.4.1, worked when nacos.core.auth.enabled=true and nacos.core.auth.enable.userAgentAuthWhite=false.
   ### The two properties is the white list for auth and used by identity the request from other server.
   nacos.core.auth.server.identity.key=serverIdentity
   nacos.core.auth.server.identity.value=security### worked when nacos.core.auth.system.type=nacos
   ### The token expiration in seconds:
   nacos.core.auth.plugin.nacos.token.expire.seconds=18000
   ### The default token:
   nacos.core.auth.plugin.nacos.token.secret.key=UmVhbGl6ZSFAIzEyMyFAI1JlYWxpemUhQCMxMjMhQCNSZWFsaXplIUAjMTIzIUAj

3. k8s里部署有状态nacos 的k8s-nacos-statefulSet-real.yaml 配置

4. springcloud 微服务yaml配置nacos控制台登录的账号密码

5. k8s一键发布nacos执行脚本,sh real.sh

echo "开始制作镜像..."
image_name=k8s-nacos-statefulSetecho "k8s一键部署"
export IMG_NAME=${image_name}
envsubst < ${image_name}'-real'.yaml | kubectl --kubeconfig ~/.kube-rz-real/config apply -f -
