在kubernetes集群中部署php应用

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 dockerfile FROM 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-xmlrpc ?RUN 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.yaml apiVersion: 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.yaml ??apiVersion: 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.conf server { ???????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
