本文将介绍在kubernetes环境中部署一套php应用系统。
前端web采用nginx、中间件php以fastcgi的方式运行，后台数据库由mysql主从提供支撑。
各服务组件之间的调用采用dns解析服务名的方式进行，数据和配置文件持久化采用pv和pvc（基于nfs）。
一、通过dockerfile创建php镜像文件# cat dockerfileFROM docker.io/openshift/base-centos7:latestMAINTAINER ylw "ylw@fjhb.cn"RUN yum makecacheRUN yum -y install php-fpm php php-gd php-mysql php-mbstring php-xml php-mcrypt php-imap php-odbc php-pear php-xmlrpcRUN sed -i 's/listen = 127.0.0.1:9000/listen = 0.0.0.0:9000/' /etc/php-fpm.d/www.confRUN sed -i 's/listen.allowed_clients = 127.0.0.1/;listen.allowed_clients = 127.0.0.1/' /etc/php-fpm.d/www.confEXPOSE 9000CMD ["/sbin/php-fpm"]# docker build -t registry.fjhb.cn/php:0.1 .# docker push registry.fjhb.cn/php:0.1二、通过yaml文件创建ReplicationController和service# cat php-rc.yamlapiVersion: v1kind: ReplicationControllermetadata: name: php-server labels: name: php-serverspec: replicas: 2 selector: name: php-server template: metadata: labels: name: php-server spec: containers: - name: php-server image: registry.fjhb.cn/php:0.1 volumeMounts: - mountPath: /usr/share/nginx/html name: nginx-data ports: - containerPort: 9000 volumes: - name: nginx-data persistentVolumeClaim: claimName: nfs-data# cat php-svc.yamlapiVersion: v1kind: Servicemetadata: name: php-server labels: name: php-serverspec: ports: - port: 9000 protocol: TCP targetPort: 9000 selector:name: php-server# kubectl create -f php-rc.yaml# kubectl create -f php-svc.yaml三、修改nginx配置支持php# cat /home/nginx/conf.d/test.confserver {listen 80;server_name test.fjhb.cn;access_log /etc/nginx/test.fjhb.cn.accesslog main;location / {root /usr/share/nginx/html;index index.html index.htm; }location ~ \.php$ {root /usr/share/nginx/html;fastcgi_pass php-server:9000;fastcgi_index index.php;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;include fastcgi_params;}location ~ /\.ht {deny all; }}网页访问phpinfo页面测试四、下载Discuz应用部署，测试php和mysql主从的连通性下载地址：http://www.discuz.net/thread-3796882-1-1.html# mkdir /home/bbs# cd /home/bbs# unzip Discuz_X3.3_SC_UTF8.zip# mv upload/* ./通过访问网页进行部署来源：https://blog.51cto.com/ylw6006/2071866
