在Kubernetes中部署nacos 2.1.0

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）新版本 nacos 部署参考：

在Kubernetes中部署nacos 2.3.2

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：

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

如果是迁移， 可以直接将 nacos 数据库整体迁移，免去建表步骤。

创建 ingress 规则

metadata:
  annotations:

    nginx.ingress.kubernetes.io/app-root: "/nacos"
    # 下面的配置和上面的app-root效果一样，就是跳转到 /nacos
    # nginx.ingress.kubernetes.io/configuration-snippet: |
    #   rewrite ^/$ https://$host/nacos/ redirect;
  name: prod-nacos-ingress
  namespace: public
spec:
  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

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

观察有没有 ERROR 类似的日志。

常用 API 接口

获取配置文件

# 开启了认证的
curl -X GET "http://nacos-svc:8848/nacos/v1/cs/configs?dataId=<配置文件ID>&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=<配置文件ID>&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.username 和 spring.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。
