1. Download wordpresswget https://cn.wordpress.org/latest-zh_CN.zip replication code 2, create database (database I downloaded using yum, database should not be deployed in K8s cluster as far as possible) create database wordpress DEFAULT CHARACTER SET utf8;grant all on wordpress.* to 'wordpress'@'%' identified by' 123456' Copy code 3, put wordpress code into NAS storage mkdir / data-pmount-t nfs-o vers=4,minorversion=0,noresvport 12XXXXXXXxx.cn-hongkong.nas.aliyuncs.com:/ / datamv wordpress / data/ copy code 3, write dockerfile and build image (I wrote the nginx image myself, mounting configuration or using secret method can also change configuration) mkdir-p Dockerfile [root@k8s-m Dockerfile] # cat default.conf server {listen 80; server_name localhost Location / {root / usr/share/nginx/html; index index.html index.htm;} error_page 500 502 503 504 / 50x.html; location = / 50x.html {root / usr/share/nginx/html;} location ~\ .php$ {root / var/www/html; fastcgi_pass php-svc.default.svc.cluster.local:9000; fastcgi_index index.php Fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params;}} [root@k8s-m Dockerfile] # cat Dockerfile FROM nginx:1.15.4-alpineLABEL maintainer= "zhang 1232@qq.com" COPY default.conf / etc/nginx/conf.d/EXPOSE 80CMD ["nginx", "- g", "daemon off" "] # build an image (if there is no image repository To import the image to another server) [root@k8s-m Dockerfile] # docker build-t mynginx:2.0. / # View the image [root@k8s-m Dockerfile] # docker images | grep mynginxmynginx 2.0 2fd9a2724422 2 hours ago 17.7MB copy code 4, configure nginx and php1, Create and import svc and deployments of php [root @ k8s-m ~] # cat php.yamlapiVersion: v1kind: Servicemetadata: name: php-svcspec: selector: name: php ports:-port: 9000 name: http-php targetPort: 9000 protocol: TCP-apiVersion: apps/v1kind: Deploymentmetadata: name: my-php-deployspec: replicas: 3 selector: matchLabels: name: php template: metadata: labels: name: php spec : containers:-name: php image: php:7.2-fpm ports:-name: http-php containerPort: 9000 volumeMounts:-name: php-code mountPath: / var/www/html/ volumes:-name: php-code nfs: path: / wordpress/ server: 12xxxxxxxxx.cn-hongkong.nas.aliyuncs.com copy code 2, Create and import svc and deployments of nginx [root @ k8s-m ~] # cat nginx-deploy.yamlapiVersion: v1kind: Servicemetadata: name: nginx-svcspec: selector: name: nginx ports:-port: 80 name: http targetPort: 80 protocol: TCP-apiVersion: apps/v1kind: Deploymentmetadata: name: my-nginx-deployspec: replicas: 3 selector: matchLabels: name: nginx template: metadata: labels: name : nginx spec: containers:-name: nginx image: mynginx:2.0 imagePullPolicy: IfNotPresent ports:-name: http containerPort: 80 volumeMounts:-name: html mountPath: / usr/share/nginx/html/ volumes:-name: html nfs: path: / wordpress/ server: 124xxxxxxxxxxxxx -hongkong.nas.aliyuncs.com copy code 3, Check out [root@k8s-m ~] # kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT (S) AGEkubernetes ClusterIP 10.96.0.1 none 443/TCP 4h25mnginx-svc ClusterIP 10.101.81.167 none 80/TCP 99mphp-svc ClusterIP 10.111.89.228 none 9000/TCP 99m [root@k8s-m ~] # kubectl get deploy NAME READY UP-TO-DATE AVAILABLE AGEmy-nginx-deploy 3ax 3 3 3 99mmy-php-deploy 3max 3 3 100m copy code 4, Create Ingress access [root@k8s-m ~] # cat wordpress-ingress.yaml apiVersion: extensions/v1beta1kind: Ingressmetadata: name: ingress-nginxspec: rules:-host: .zhang.com http: paths:-backend: serviceName: nginx-svc servicePort: 80 [root@k8s-m ~] # kubectl apply-f wordpress-ingress.yaml ingress.extensions/ingress-nginx created copy code 5, access test

5. Installation of PHP extension

Ini extension file path in the php container: / usr/local/etc/php/conf.d/

1. Enter [root@node1 ~] # docker run-it-- name php-gd php:7.2-fpm bash copy code 2 in the php container, download copy code depending on apt-get update & & apt-get install libfreetype6-dev libjpeg62-turbo-dev libmcrypt-dev libpng-dev-y, install extensions (such as GD), install docker-php-ext-install gd#, install docker-php-ext-enable gd replication code 4, Save the container as a new image [root@node1 ~] # docker commit-p php-gd php-gd:1.0sha256:c562ad539630b3c5eb6888f0b7bac937d9d3af1d39de118106c5e6ca30a02ebd [root@node1 ~] # docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEphp-gd 1.0 c562ad539630 4 seconds ago 426MB copy code 5, Run the new php container to test [root@node1] # docker run-it-- rm php-gd:1.0 bash root@9e7fa8e57db7:/var/www/html# ls / usr/local/etc/php/conf.d/docker-php-ext-gd.ini / usr/local/etc/php/conf.d/docker-php-ext-gd.iniroot@9e7fa8e57db7:/var/www/html# cat / usr/local/etc/php/conf.d/docker-php-ext-gd.ini Extension=gd.soroot@9e7fa8e57db7:/var/www/html# php-m | grep gdgd copy code 6. Extensions such as redis install curl-L-o redis-4.1.1.tar.gz https://github.com/phpredis/phpredis/archive/4.1.1.tar.gztar xf redis-4.1.1.tar.gz rm redis-4.1.1.tar.gz mv phpredis-4.1.1 / usr/src/php/ext/redisdocker-php-ext-configure redisdocker-php-ext-install redisdocker-php-ext-enable redis copy code
