本次在 Kubernetes 上部署 nacos 2.1.0 版本, 部署3节点集群,不做数据持久化(nacos的配置管理是存储MySQL数据库的,服务发现是需要本地存储的)

MySQL数据库准备

创建数据库,配置好账号权限,执行如下SQL建表:

ingressClassName: "public-nginx" # 这里是ingressclass名字, 新版本k8s用这个
rules:
- host: 这里修改为nacos的域名
http:
paths:
- backend:
service:
name: nacos-svc
port:
number: 8848
path: /
pathType: ImplementationSpecific
tls:
- hosts:
- 这里修改为nacos的域名
secretName: i-com # 这里配置ssl证书的secret名字

ingress规则作用是让网页控制台域名转发到8848端口,如果不需要域名,可以在service上开nodeport,用ip+端口来访问。

检查部署情况

部署完成后, 进入nacos的pod,

cat /home/nacos/conf/cluster.conf


#2023-11-21T14:48:56.695
nacos-0.nacos-headless.public.svc.cluster.local:8848
nacos-1.nacos-headless.public.svc.cluster.local:8848
nacos-2.nacos-headless.public.svc.cluster.local:8848

3节点的nacos,这里应该是3行配置。

检查控制台

状态为 UP 集群正常。

检查集群状态日志

1
cat /home/nacos/logs/naming-server.log

观察有没有ERROR类似的日志。

常用API接口

# 开启了认证的
curl -X GET "http://nacos-svc:8848/nacos/v1/cs/configs?dataId=idp-oms&group=DEFAULT_GROUP&tenant=uat&username=nacos&password=nacos"

# 未开启认证
curl -X GET "http://nacos-svc:8848/nacos/v1/cs/configs?dataId=idp-tsp&group=DEFAULT_GROUP&tenant=sit"

tenant 命名空间
dataID 配置文件名
group 分组,默认为 DEFAULT_GROUP

关闭双写

curl -X PUT 'http://nacos-svc:8848/nacos/v1/ns/operator/switches?entry=doubleWriteEnabled&value=false&username=nacos&password=nacos'

常见问题

nacos 修改密码不成功

修改密码提示已修改,并自动注销,登录时新密码无法登录,生效的还是旧密码

需要先将 NACOS_AUTH_ENABLE 关闭, 修改完成密码后再开启。

账号登录后马上退出,提示没有权限

账号登录后现实的是 public 命名空间,如果没有 public 命名空间的权限就会自动退出。

执行sql建表的时候,提示 Specified key was too long; max key length is 767 bytes

需要修改MySQL innodb_large_prefix 为 ON

-- 查看参数
show variables like 'innodb_large_prefix';

-- 修改参数
set global innodb_large_prefix = ON;

如果MySQL不允许修改参数, 那么也可以修改 nacos 的 SQL

-- resource varchar(255) 这里长度改成150
CREATE TABLE `permissions` (
`role` varchar(50) NOT NULL,
`resource` varchar(150) NOT NULL,
`action` varchar(8) NOT NULL,
UNIQUE INDEX `uk_role_permission` (`role`,`resource`,`action`) USING BTREE
);

忘记密码 重置密码

重置账号 nacos 密码 为 nacos

UPDATE `nacos`.`users` SET `password` = '$2a$10$EuWPZHzz32dJN7jexM34MOeYirDdFAZm2kuWj7VEOJhhZkDrxfvUu', `enabled` = 1 WHERE `username` = 'nacos';
UPDATE `nacos`.`roles` SET  `role` = 'ROLE_ADMIN' WHERE `username` = 'nacos';

业务报错 unknown user

检查一下:

  • 业务连上nacos后,会拉取一份配置文件到本地缓存,缓存位置在 ~/nacos/config 目录下, 确认下这里是否拉取了配置文件。
  • nacos 服务管理 服务列表中是否成功注册了节点(业务使用了nacos服务发现)
  • 使用API接口来获取配置文件是否正常获取到

需要注意的:

  • 尽量不要使用public命名空间,创建一个新的命名空间,命名空间ID设置和命名空间名字一样,业务配置也要指定配置namespace和服务发现namespace
  • 环境变量:spring.cloud.nacos.usernamespring.cloud.nacos.password 看情况配置下,我就遇到过nacos没开鉴权,但是必须要配置这两个参数的情况。
