k8s的LNMP部署

<>架构图：



<>镜像

首先我们将nginx和php镜像准备好，并且将其推送到镜像仓库中：
自己没有Dockerfile文件得可以下载我的：
https://download.csdn.net/download/qq_25611295/10672202
<https://download.csdn.net/download/qq_25611295/10672202>
docker login 192.168.1.40:5000 nginx: docker build -t
192.168.1.40:5000/lnmp/nginx . docker push 192.168.1.40:5000/lnmp/nginx php：
docker bulid -t 192.168.1.40:5000/lnmp/php . docker push
192.168.1.40:5000/lnmp/php mysql: docker pull mysql:5.6 docker tag 1f47fade220d
192.168.1.40/lnmp/mysql docker push 192.168.1.40:5000/lnmp/mysql
检测仓库：

<https://blog.csdn.net/qq_25611295/article/details/80967135>
[root@k8s-g1 ~]# curl -u liaochao:123456 192.168.1.40:5000/v2/_catalog
{"repositories":["lnmp/mysql","lnmp/nginx","lnmp/php","nginx","php"]}
<>认证：

镜像准备好以后我们需要配置一些认证文件，比如，mysql的账户密码，仓库的账户密码等等，我们需要将这些放入k8s的认证中
mysql:
创建mysql密码的认证
kubectl create secret generic mysql-pass --from-literal=password=123456
检测：
[root@master LNMP]# kubectl get secret NAME TYPE DATA AGE default-token-5bjhk
kubernetes.io/service-account-token 3 24d liaochao-https kubernetes.io/tls 2 6d
mysql-pass Opaque 1 19s
创建仓库认证：
查看认证信息：（bash64 -wo 代表以64位转码展示并且不换行）
cat .docker/config.json |base64 -w0
然后我们根据得到的数据创建认证：
[root@master LNMP]# cat docker-secret.yaml apiVersion: v1 kind: Secret
metadata: name: registrypullsecret data: .dockerconfigjson:
ewoJImF1dGhzIjogewoJCSIxOTIuMTY4LjEuNDA6NTAwMCI6IHsKCQkJImF1dGgiOiAiYkdsaGIyTm9ZVzg2TVRJek5EVTIiCgkJfQoJfSwKCSJIdHRwSGVhZGVycyI6IHsKCQkiVXNlci1BZ2VudCI6ICJEb2NrZXItQ2xpZW50LzE4LjA2LjAtY2UgKGxpbnV4KSIKCX0KfQ==
type: kubernetes.io/dockerconfigjson
创建
kubectl create -f docker-secret.yaml
检测：
[root@master LNMP]# kubectl get secret NAME TYPE DATA AGE default-token-5bjhk
kubernetes.io/service-account-token 3 24d liaochao-https kubernetes.io/tls 2 7d
mysql-pass Opaque 1 23m registrypullsecret kubernetes.io/dockerconfigjson 1 12s
<>配置lnmp环境

pv 数据存储：
[root@master LNMP]# cat pv.yaml apiVersion: v1
#使用glusterfs做存储，不懂glusterfs的请参考其他文章 kind: PersistentVolume metadata: name:
mysql-pv spec: capacity: storage: 20Gi accessModes: - ReadWriteMany glusterfs:
endpoints: "glusterfs-cluster" path: "gv1" --- #使用nfs做存储 apiVersion: v1 kind:
PersistentVolume metadata: name: wp-pv spec: capacity: storage: 5Gi
accessModes: - ReadWriteMany nfs: path: /opt/container_data/wp-wwwroot server:
192.168.1.39
php配置:
[root@master LNMP]# cat php-deployment.yaml apiVersion: v1 kind: Service
metadata: name: wordpress-php labels: app: wordpress spec: ports: - port: 9000
selector: app: wordpress-php tier: frontend --- apiVersion: v1 kind:
PersistentVolumeClaim metadata: name: wp-pvc labels: app: wordpress spec:
accessModes: - ReadWriteMany resources: requests: storage: 5Gi --- apiVersion:
apps/v1beta2 # for versions before 1.8.0 use apps/v1beta1 kind: Deployment
metadata: name: wordpress-php labels: app: wordpress spec: replicas: 3
selector: matchLabels: app: wordpress-php tier: frontend strategy: type:
Recreate template: metadata: labels: app: wordpress-php tier: frontend spec:
containers: - name: php image: 192.168.1.40:5000/lnmp/php ports: -
containerPort: 9000 name: wordpress volumeMounts: #用于php解析的目录 - name:
wordpress-persistent-storage mountPath: /var/www/html ##拉取镜像时的用户认证,没有的时候注释掉这2行
imagePullSecrets: - name: registrypullsecret volumes: - name:
wordpress-persistent-storage persistentVolumeClaim: claimName: wp-pvc
nginx配置：
此处nginx和php共用一个pv,pvc
[root@master LNMP]# cat nginx-deployment.yaml apiVersion: v1 kind: ConfigMap
metadata: name: nginx-wp-config data: site.conf: |- server { listen 80;
server_name localhost; root html; index index.html index.php; location ~ \.php$
{ root html; fastcgi_pass wordpress-php:9000; fastcgi_param SCRIPT_FILENAME
/var/www/html$fastcgi_script_name; include fastcgi_params;
fastcgi_connect_timeout 60s; fastcgi_read_timeout 300s; fastcgi_send_timeout
300s; } } --- apiVersion: v1 kind: Service metadata: name: wordpress-nginx
labels: app: wordpress spec: ports: - port: 80 selector: app: wordpress-nginx
tier: frontend type: NodePort sessionAffinity: ClientIP --- apiVersion:
apps/v1beta2 kind: Deployment metadata: name: wordpress-nginx labels: app:
wordpress spec: replicas: 3 selector: matchLabels: app: wordpress-nginx tier:
frontend strategy: type: Recreate template: metadata: labels: app:
wordpress-nginx tier: frontend spec: containers: - name: nginx image:
192.168.1.40:5000/lnmp/nginx ports: - containerPort: 80 name: wordpress
volumeMounts: - name: wordpress-persistent-storage mountPath:
/usr/local/nginx/html - name: config mountPath:
/usr/local/nginx/conf/vhost/site.conf subPath: site.conf imagePullSecrets: -
name: registrypullsecret volumes: - name: wordpress-persistent-storage
persistentVolumeClaim: claimName: wp-pvc - name: config configMap: name:
nginx-wp-config
yaml文件准备好以后，创建：
kubectl create -f mysql-deployment.yaml kubectl create -f php-deployment.yaml
kubectl create -f nginx-deployment.yaml
检测存储：
kubectl get pv,pvc [root@k8s-g1 lnmp]# kubectl get pv,pvc NAME CAPACITY ACCESS
MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
persistentvolume/mysql-pv 20Gi RWX Retain Bound default/mysql-pv-claim 17m
persistentvolume/wp-pv 5Gi RWX Retain Bound default/wp-pvc 2h NAME STATUS
VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
persistentvolumeclaim/mysql-pv-claim Bound mysql-pv 20Gi RWX 17m
persistentvolumeclaim/wp-pvc Bound wp-pv 5Gi RWX 2h
检测节点：(保证所有节点都是running)
kubectl get pod -o wide
检测nginx servers暴露出来的端口：
kubectl get svc
然后根据nginxserver暴露出来的端口测试nginx页面是否能访问
http://192.168.1.40:49665/ <http://192.168.1.40:49665/>
利用phpinfo测试php解析
[root@master wp-wwwroot]# cat test.php <?php phpinfo(); ?>
<>部署wordpress

此处我们将nfs挂载的共享路径为：/opt/container_data/wp-wwwroot/
我们将wordpress放在此处：
数据库选择：wordpress ，主机名为：wordpress-mysql，账户密码选择：root 123456
