Operator-mysql安装
1、helm添加库
helm安装不做说明
helm repo add presslabs https://presslabs.github.io/charts
helm repo update
helm pull presslabs/mysql-operator
创建rabc.yaml
# 唯一需要修改的地方只有namespace,根据实际情况定义
apiVersion: v1
kind: ServiceAccount
metadata:
name: nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: zhanghsn #根据实际环境设定namespace,下面类同
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: nfs-client-provisioner-runner
namespace: zhanghsn
rules:
- apiGroups: [""]
resources: ["persistentvolumes"]
verbs: ["get", "list", "watch", "create", "delete"]
- apiGroups: [""]
resources: ["persistentvolumeclaims"]
verbs: ["get", "list", "watch", "update"]
- apiGroups: ["storage.k8s.io"]
resources: ["storageclasses"]
verbs: ["get", "list", "watch"]
- apiGroups: [""]
resources: ["events"]
verbs: ["create", "update", "patch"]
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: run-nfs-client-provisioner
subjects:
- kind: ServiceAccount
name: nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: zhanghsn
roleRef:
kind: ClusterRole
name: nfs-client-provisioner-runner
apiGroup: rbac.authorization.k8s.io
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: leader-locking-nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: zhanghsn
rules:
- apiGroups: [""]
resources: ["endpoints"]
verbs: ["get", "list", "watch", "create", "update", "patch"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: leader-locking-nfs-client-provisioner
subjects:
- kind: ServiceAccount
name: nfs-client-provisioner
# replace with namespace where provisioner is deployed
namespace: zhanghsn
roleRef:
kind: Role
name: leader-locking-nfs-client-provisioner
apiGroup: rbac.authorization.k8s.io
2、创建StorageClass
说明：我这里使用的是CCE，插件装好nfs，这里不需要操作
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: presslabs-managed-nfs-storage
namespace: operator
provisioner: presslabs-mysql-nfs-storage #这里的名称要和provisioner配置文件中的环境变量PROVISIONER_NAME保持一致parameters: archiveOnDelete: "false"
3、安装operator
[root@cce-master1 mysql-rabc]# kubectl apply -f ./rabc.yaml
helm install presslabs-mysql-operator -name mysql-operator -f mysql-operator/values.yaml --namespace zhanghsn --set rbac.enabled=true
[root@cce-master1 mysql-rabc]# kubectl get ServiceAccount,ClusterRole,ClusterRoleBinding,Role,RoleBinding -n zhanghsn
[root@cce-master1 soft]# kubectl get pod,svc,ing,cm -n zhanghsn
Warning: extensions/v1beta1 Ingress is deprecated in v1.14+, unavailable in v1.22+; use networking.k8s.io/v1 Ingress
NAME READY STATUS RESTARTS AGE
pod/presslabs-mysql-operator-0 2/2 Running 0 4m23s

#更新values.yaml,可以将副本修改
[root@cce-master1 soft]# helm upgrade presslabs-mysql-operator --values mysql-operator/values.yaml mysql-operator --namespace zhanghsn --set rbac.enabled=true
[root@cce-master1 mysql-rabc]# kubectl get pod -n zhanghsn -o wide|grep operator
presslabs-mysql-operator-0 2/2 Running 0 7m 172.16.169.72 10.11.95.235 <none> <none>
presslabs-mysql-operator-1 2/2 Running 0 7m5s 172.16.169.109 10.11.95.235 <none> <none>
presslabs-mysql-operator-2 2/2 Running 0 7m20s 172.16.169.86 10.11.95.235 <none> <none>
[root@cce-master1 mysql-rabc]#
4版本镜像起不来，换位3版本镜像
里面的operator容器和orchestrator容器都会有选主的过程，这里对应的应该是presslabs-mysql-operator-2， Operator POD在起来之后，其中给一个会成为leader leader的ip是svc的ip 会出现如下字样
2020/09/30 01:37:59 [INFO] raft: Election won. Tally: 2
2020/09/30 01:37:59 [INFO] raft: Node at 10.109.138.165:10008 [Leader] entering Leader state
4、查看
kubectl log -f presslabs-mysql-operator-2 -c orchestrator -n operator
#骚操作，如果pod起不来，可以先把健康检查关闭mysql-cluster是依赖他
4、安装mysql集群
[root@cce-master1 soft]# helm pull presslabs/mysql-cluster
vim values.yaml #修改副本数和mysql的用户密码
replicas: 3
helm install presslabs-mysql-cluster --name mysql-cluster -f values.yaml --namespace zhanghsn --set rbac.enabled=true
helm delete my-cluster --purge
helm uninstall my-cluster
[root@cce-master1 mysql-rabc]# kubectl get pod -n zhanghsn -o wide
