Centos7二进制部署k8s-v1.20.2 ipvs版本(部署mysql、nacos)

一、部署mysql容器
1、创建yaml文件

mkdir /data/docker_volume  -p
vim mysql-rc.yaml
apiVersion: v1
kind: ReplicationController
metadata:
  name: mysql-rc
  labels:
    name: mysql-rc
spec:
  replicas: 1
  selector:
    name: mysql-pod
  template:
    metadata:
      annotations:
      labels:
        name: mysql-pod
    spec:
      containers:
      - env:
        - name: MYSQL_ROOT_PASSWORD
          value: mysql                                  #mysql的root密码
        image: mysql
        imagePullPolicy: IfNotPresent
        name: mysql
        ports:
        - containerPort: 3306
          name: mysql
          protocol: TCP
        volumeMounts:
        - mountPath: /var/lib/mysql
          name: mysql
      dnsPolicy: ClusterFirst
      nodeName: k8s-node1                               #固定安装在哪台节点上
      restartPolicy: Always
      schedulerName: default-scheduler
      terminationGracePeriodSeconds: 30
      volumes:
      - hostPath:
          path: /data/docker_volume/mysql               #节点上记得创建这个目录
          type: ""
        name: mysql
---
apiVersion: v1
kind: Service
metadata:
  name: mysql-svc
  labels:
    name: mysql-svc
spec:
  type: NodePort
  ports:
  - port: 3306
    protocol: TCP
    targetPort: 3306
    name: http
    nodePort: 33306
  selector:
    name: mysql-pod

2、创建容器

kubectl apply -f mysql.yaml -n component

3、登录容器

kubectl exec -it mysql-rc-tvpgs -n component -- /bin/bash
#在容器内登录mysql。执行以下命令,-h为ip,容器内ip为127.0.0.1,-r为用户名,-p为密码,在mysql-rc中设置的密码。
mysql -h127.0.0.1 -uroot -pmysql

二、导入nacos需要的mysql数据库
1、进入容器

vim nacos-mysql.sql

2、导入nacos预置数据

mysql -h127.0.0.1 -uroot -pmysql
create database nacos;
use nacos;
source nacos-mysql.sql;

三、部署nacos容器
1、修改yaml文件

vim nacos.yaml

2、创建容器

kubectl apply -f nacos.yaml
