helm一键 安装mariadb-ha详细

一、

 

二、单机安装一主一从

　　先创建对应pv

　　 https://github.com/helm/charts/blob/master/stable/mariadb/templates/master-statefulset.yaml

       MysqL-ha-pv00.yaml

apiVersion: v1
kind: PersistentVolume
Metadata:
      name: mariadb-master
      labels:
        app: mariadb
spec:
 capacity:
  storage: 10Gi
 accessModes:
  - ReadWriteOnce
 hostPath:
  path: /opt/mariadb-master

　　　MysqL-ha-pv01.yaml

apiVersion: v1
kind: PersistentVolume
Metadata:
      name: mariadb-slave
      labels:
        app: mariadb
spec:
 capacity:
  storage: 10Gi
 accessModes:
  - ReadWriteOnce
 hostPath:
  path: /opt/mariadb-slave

　　kubectl create -f MysqL-ha-pv00.yaml
　　kubectl create -f MysqL-ha-pv01.yaml

三、安装MysqL

　　#修改密码和修改主库的pvc，默认都有pvc

　　helm install --name mariadb-ha --set rootUser.password="123456" --set master.persistence.existingClaim=mariadb-master stable/mariadb

      #启动后查看pod容器日志，提示没权限创建目录或初始化失败，需要修改宿主目录的权限为1001，因为容器默认以1001的用户启动

　  chown 1001:root /opt/mariadb-master

      chown 1001:root /opt/mariadb-slave

 　kubectl get all查看是否成功

 

四、安装成功后，查看MysqL密码

kubectl get secret --namespace default mariadb-ha -o jsonpath="{.data.mariadb-root-password}" | base64 --decode
