简介： k8s安装并迁移jumpserver

一、环境

二、安装依赖服务

以下操作按需操作

1.安装Helm

wget  https://get.helm.sh/helm-v3.12.1-linux-amd64.tar.gz
tar xf  helm-v3.12.1-linux-amd64.tar.gz
mv linux-amd64/helm /usr/local/bin/
helm version
helm repo add jumpserver https://jumpserver.github.io/helm-charts  #添加jumpserver chart仓库
helm repo list

2.修改github解析

访问https://sites.ipaddress.com/github.com/#ipinfo获取github.com最新解析IP并配置部署机器hosts文件

140.82.113.3 github.com #如果不行访问该网站https://ping.chinaz.com/github.com挑选响应最快的IP

3.安装MySQL

namespace

kubectl create namespace jumpserver

pvc.yaml(storageClass根据实际情况修改)

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  annotations:
    volume.beta.kubernetes.io/storage-provisioner: nasplugin.csi.alibabacloud.com
  name: mysql-data
  namespace: jumpserver
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 50Gi
  storageClassName: alicloud-disk-nas

config.yaml

kind: ConfigMap
apiVersion: v1
metadata:
  name: mysql-config
  namespace: jumpserver
data:
  my.cnf: |-
    [mysqld]
    skip-host-cache
    skip-name-resolve
    datadir=/var/lib/mysql
    socket=/var/run/mysqld/mysqld.sock
    secure-file-priv=/var/lib/mysql-files
    user=mysql
    symbolic-links=0
    pid-file=/var/run/mysqld/mysqld.pid
    [client]
    socket=/var/run/mysqld/mysqld.sock
    !includedir /etc/mysql/conf.d/
    !includedir /etc/mysql/mysql.conf.d/

deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: jumpserver-mysql
  namespace: jumpserver
spec:
  selector:
    matchLabels:
      app: mysql-5.7
  template:
    metadata:
      labels:
        app: mysql-5.7
    spec:
      containers:
      - name: mysql
        image: mysql:5.7.42
        env:                        
        - name: MYSQL_ROOT_PASSWORD
          value: "System@123"
        ports:
        - containerPort: 3306
        volumeMounts:
        - name: mysql-data
          mountPath: /var/lib/mysql         
          subPath: mysql
        - name: config
          mountPath:  /etc/my.cnf
          subPath: my.cnf
      volumes:
      - name: mysql-data
        persistentVolumeClaim:
          claimName: mysql-data
      - name: config
        configMap:
          name: mysql-config

svc.yaml

apiVersion: v1
kind: Service
metadata:
  labels:
    app: jumpserver-mysql-svc
  name: jumpserver-mysql-svc
  namespace: jumpserver
spec:
  ports:
  - name: tcp-mysql-3306
    nodePort: 30306
    port: 3306
    protocol: TCP
    targetPort: 3306
  selector:
    app: mysql-5.7
  type: NodePort

部署后创建数据库

kubectl get pods -n jumpserver -o wide

mysql -uroot -h 172.17.0.5 -p

CREATE DATABASE IF NOT EXISTS jumpserver DEFAULT CHARSET utf8mb4 COLLATE utf8mb4_general_ci;

4.安装Redis

pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  annotations:
    volume.beta.kubernetes.io/storage-provisioner: nasplugin.csi.alibabacloud.com
  name: redis-data
  namespace: jumpserver
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 20Gi
  storageClassName: alicloud-disk-nas

config.yaml

apiVersion: v1
data:
  redis.conf: |-
    bind 0.0.0.0
    port 6379
    requirepass System@123
    pidfile /var/run/redis_6379.pid
    save 900 1
    save 300 10
    save 60 10000
    rdbcompression yes
    rdbchecksum yes
    dbfilename dump.rdb
    appendonly yes
    appendfilename "appendonly.aof"
    appendfsync everysec
    dir /data
    logfile "/data/redis-6379.log"
kind: ConfigMap
metadata:
  name: redis-config
  namespace: jumpserver

deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: jumpserver-redis
  namespace: jumpserver
spec:
  replicas: 1
  selector:
    matchLabels:
      app: jumpserver-redis
  template:
    metadata:
      labels:
        app: jumpserver-redis
    spec:
      containers:
      - image: redis:6.0.9
        command: ["redis-server","/etc/redis/redis.conf"]
        name: redis
        ports:
        - containerPort: 6379        
        volumeMounts:
        - name: redis-config
          mountPath: /etc/redis/redis.conf
          subPath: redis.conf
        - name: redis-data
          mountPath: /data
      volumes:
      - name: redis-config
        configMap:
          name: redis-config
      - name: redis-data
        persistentVolumeClaim:
          claimName: redis-data

svc.yaml

apiVersion: v1
kind: Service
metadata:
  labels:
    app: jumpserver-redis-svc
  name: jumpserver-redis-svc
  namespace: jumpserver
spec:
  ports:
  - name: tcp-redis-6379
    port: 6379
    protocol: TCP
    targetPort: 6379
  selector:
    app: jumpserver-redis

三、修改配置

1.下载配置

wget https://raw.githubusercontent.com/jumpserver/helm-charts/main/charts/jumpserver/values.yaml

2.修改镜像仓库地址

3.配置SC

4.配置MySQL和Redis

5.配置ingress hosts

6.配置秘钥

其余配置按需修改

四、部署jumpserver

helm install jms-k8s jumpserver/jumpserver -n jumpserver -f values.yaml
[root@iZbp10kr3w2ijv03yu6htrZ jumpserver]# helm -n jumpserver ls -a
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
jms-k8s jumpserver 1 2023-07-13 11:50:39.910210139 +0800 CST deployed jumpserver-3.4.3 v3.4.3
[root@iZbp10kr3w2ijv03yu6htrZ jumpserver]# kubectl get pods -n jumpserver
NAME READY STATUS RESTARTS AGE
jms-k8s-jumpserver-jms-celery-59d99c46b6-mg9z4 1/1 Running 0 67s

jms-k8s-jumpserver-jms-web-7b6c46b6c4-hsjg9 1/1 Running 0 67s
jumpserver-mysql-77656bd48-svkb9 1/1 Running 0 24h
jumpserver-redis-75898bdd9-rs8kg 1/1 Running 0 24h

五、登录验证

访问ingress域名(绑定hosts或者配置NDS解析)

登录用户密码：admin/admin

如果只是搭建那么此时就完成了

六、导入原数据库数据到新数据库

由于我的服务都在阿里云所以这里使用阿里云的DTS服务的数据迁移功能(免费)，本地可以使用mysqldump或其他工具

七、重启服务

kubectl delete pods -n jumpserver -l app.kubernetes.io/name=jumpserver

八解决报错

1.报错内容

{"error":"service account registration disabled"}

2.解决方法

登录jumpserver(用户、密码、MFA与原jumpserver一致),系统设置--安全设置--终端注册

3.重启报错应用

for i in `kubectl get deployments.apps -n jumpserver|awk '/0\/1/  {print $1}'` ;do kubectl scale deployment ${i} --replicas=0 -n  jumpserver;done
for i in `kubectl get deployments.apps -n jumpserver|awk '/0\/0/  {print $1}'` ;do kubectl scale deployment ${i} --replicas=1 -n  jumpserver;done
root@iZbp10kr3w2ijv03yu6htrZ ~]# kubectl get pods -n jumpserver -o wide

4.控制台确认并删除无效终端应用

至此所以操作完毕
