一、配置文件

1.初始化数据库

wget https://raw.githubusercontent.com/alibaba/nacos/develop/distribution/conf/mysql-schema.sql
mysql -uroot -p
CREATE DATABASE IF NOT EXISTS nacos_config DEFAULT CHARSET utf8mb4 COLLATE utf8mb4_general_ci;
use nacos_config;
source  /root/mysql-schema.sql;
CREATE USER 'nacos'@'%' IDENTIFIED BY 'WKjIjQZ1ub3V5qSd'; #不能包含特殊字符
GRANT ALL PRIVILEGES ON nacos_config.* TO 'nacos'@'%';
FLUSH PRIVILEGES;
exit;

2.创建nacos配置文件

apiVersion: v1
kind: ConfigMap
metadata:
  name: t1-zdbl-nacos-cm
  namespace: t1-zdbl
data:
  mysql.host: "t1-zdbl-mysql.t1-zdbl.svc.cluster.local"
  mysql.db.name: "nacos_config"
  mysql.port: "3306"
  mysql.user: "t1_zdbl_nocos"
  mysql.password: "xxxxxx"  #注意此处的密码不要包含特殊字符，否则在开启鉴权的情况下可能导致客户端连接错误，报403

3.创建nacos deploy部署文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: t1-zdbl-nacos
  namespace: t1-zdbl
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: t1-zdbl-nacos
    spec:
      containers:
        - name: k8snacos
          image: nacos/nacos-server:v2.2.0
          resources:
            requests:
              memory: "1Gi"
              cpu: "500m"
          ports:
            - containerPort: 8848
              name: client
            - containerPort: 9848
              name: client-rpc
            - containerPort: 9849
              name: raft-rpc
            - containerPort: 7848
              name: old-raft-rpc
          env:
            - name: SPRING_DATASOURCE_PLATFORM
              value: "mysql"
            - name: MYSQL_SERVICE_HOST
              valueFrom:
                configMapKeyRef:
                  name: t1-zdbl-nacos-cm
                  key: mysql.host
            - name: MYSQL_SERVICE_DB_NAME
              valueFrom:
                configMapKeyRef:
                  name: t1-zdbl-nacos-cm
                  key: mysql.db.name
            - name: MYSQL_SERVICE_PORT
              valueFrom:
                configMapKeyRef:
                  name: t1-zdbl-nacos-cm
                  key: mysql.port
            - name: MYSQL_SERVICE_USER
              valueFrom:
                configMapKeyRef:
                  name: t1-zdbl-nacos-cm
                  key: mysql.user
            - name: MYSQL_SERVICE_PASSWORD
              valueFrom:
                configMapKeyRef:
                  name: t1-zdbl-nacos-cm
                  key: mysql.password
            - name: MODE
              value: "standalone"
            - name: NACOS_SERVER_PORT
              value: "8848"
            - name: PREFER_HOST_MODE
              value: "hostname"
            - name: NACOS_AUTH_ENABLE  #开启鉴权
              value: "true"
            - name: NACOS_AUTH_IDENTITY_KEY
              value: "nacosAuthKey"
            - name: NACOS_AUTH_IDENTITY_VALUE
              value: "nacosSecurtyValue"
            - name: NACOS_AUTH_TOKEN
              value: "SecretKey012345678901234567890123456789012345678901234567890123456789"
            - name: NACOS_AUTH_TOKEN_EXPIRE_SECONDS
              value: "18000"  
  selector:
    matchLabels:

    - port: 9849
      name: raft-rpc
      targetPort: 9849
    - port: 7848
      name: old-raft-rpc
      targetPort: 7848
  selector:
    app: t1-zdbl-nacos

5.创建nacos ingress文件

  annotations:
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80},{"HTTPS": 443}]'
    alb.ingress.kubernetes.io/ssl-redirect: "true"

  rules:
   - host: t1-zdbl-nacos.xxxxx.com
     http:
      paths:
      - path: /
        pathType: Prefix
