MySQL Operator 第三篇

简介：

　　PXC Operator由Percona基于SDK创建，文档详细，有很好的维护，是MySQL Operator很好的参考案例，这里只做简单的部署实验。详细信息查看官方文档：

1、部署Opeartor

# 下载代码
git clone -b v1.9.0 https://github.com/percona/percona-xtradb-cluster-operator
cd percona-xtradb-cluster-operator


kubectl apply -f deploy/crd.yaml
kubectl create namespace pxc
kubectl config set-context $(kubectl config current-context) --namespace=pxc
kubectl apply -f deploy/rbac.yaml
kubectl apply -f deploy/operator.yaml

2、部署PXC

kubectl create -f deploy/secrets.yaml
cp deploy/cr.yaml deploy/pxc.yaml

编辑 deploy/pxc.yaml

        volume:
          persistentVolumeClaim:
            storageClassName: standard   # 写上你自己的SC名字
            accessModes: [ "ReadWriteOnce" ]
            resources:
              requests:
                storage: 6G       

# 如果没有SC可以自己创建三个PV做测试用,metadata.name不同就行(上面修改过SC就可以省略了)
apiVersion: v1
kind: PersistentVolume
metadata:
  name: pxc-pv-volume-0
  labels:
    type: local
spec:
  capacity:
    storage: 6Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/data/pxc"

mkdir /data/pxc
chown 99:1001 /data/pxc -R
chmod 775 /data/pxc -R

注意：按理说，这里不用创建目录并且赋予权限，可是如果不提前加的话，pxc-init初始化容器
会报install: cannot create regular file '/var/lib/mysql/pxc-entrypoint.sh': Permission denied

kubectl apply -f deploy/pxc.yaml
