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
