1、下载wordpress
wget https://cn.wordpress.org/latest-zh_CN.zip复制代码
2、创建数据库（数据库我使用yum下载的，数据库尽量不要部署在k8s集群中）
create database wordpress DEFAULT CHARACTER SET utf8; grant all on wordpress.* to 'wordpress'@'%' identified by '123456';复制代码
3、把wordpress代码放入到NAS存储中
mkdir /data -p mount -t nfs -o vers=4,minorversion=0,noresvport 12XXXXXXXxx.cn-hongkong.nas.aliyuncs.com:/ /data mv wordpress /data/复制代码
三、写dockerfile和构建镜像（我这自己写的nginx镜像，挂载配置或者使用secret的方法也能更改配置）
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-alpine
LABEL maintainer="zhang 1232@qq.com"COPY default.conf /etc/nginx/conf.d/
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]#构建镜像（没有镜像仓库的话，要把镜像导入到其它服务器上）[root@k8s-m Dockerfile]# docker build -t mynginx:2.0 ./#查看镜像[root@k8s-m Dockerfile]# docker images|grep mynginxmynginx 2.0 2fd9a2724422 2 hours ago 17.7MB复制代码
四、配置nginx和php
1、创建与导入php的svc和deploy
[root@k8s-m ~]# cat php.yamlapiVersion: v1 kind: Service metadata: name: php-svc spec: selector: name: php ports: - port: 9000 name: http-php targetPort: 9000 protocol: TCP --- apiVersion: apps/v1 kind: Deployment metadata: name: my-php-deploy spec: 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复制代码
2、创建与导入nginx的svc和deploy
[root@k8s-m ~]# cat nginx-deploy.yamlapiVersion: v1 kind: Service metadata: name: nginx-svc spec: selector: name: nginx ports: - port: 80 name: http targetPort: 80 protocol: TCP --- apiVersion: apps/v1 kind: Deployment metadata: name: my-nginx-deploy spec: 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复制代码
3、查看
[root@k8s-m ~]# kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.96.0.1 none 443/TCP 4h25m nginx-svc ClusterIP 10.101.81.167 none 80/TCP 99m php-svc ClusterIP 10.111.89.228 none 9000/TCP 99m [root@k8s-m ~]# kubectl get deploy NAME READY UP-TO-DATE AVAILABLE AGE my-nginx-deploy 3/3 3 3 99m my-php-deploy 3/3 3 3 100m复制代码
4、创建Ingress访问
[root@k8s-m ~]# cat wordpress-ingress.yaml apiVersion: extensions/v1beta1 kind: Ingress metadata: name: ingress-nginx spec: rules: - host: haha.zhang.com http: paths: - backend: serviceName: nginx-svc servicePort: 80 [root@k8s-m ~]# kubectl apply -f wordpress-ingress.yaml ingress.extensions/ingress-nginx created复制代码
5、访问测试
五、PHP扩展安装
php容器中的ini扩展文件路径：/usr/local/etc/php/conf.d/
1、进入php容器中
[root@node1 ~]# docker run -it --name php-gd php:7.2-fpm bash复制代码
2、下载依赖
apt-get update && apt-get install libfreetype6-dev libjpeg62-turbo-dev libmcrypt-dev libpng-dev -y复制代码
3、安装扩展（例如GD）
docker-php-ext-configure gd#安装docker-php-ext-install gd#启用docker-php-ext-enable gd复制代码
4、将容器保存为新的镜像
[root@node1 ~]# docker commit -p php-gd php-gd:1.0sha256:c562ad539630b3c5eb6888f0b7bac937d9d3af1d39de118106c5e6ca30a02ebd [root@node1 ~]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZE php-gd 1.0 c562ad539630 4 seconds ago 426MB复制代码
5、运行新php容器测试
[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.ini root@9e7fa8e57db7:/var/www/html# cat /usr/local/etc/php/conf.d/docker-php-ext-gd.ini extension=gd.so root@9e7fa8e57db7:/var/www/html# php -m|grep gdgd复制代码
6、redis之类的扩展安装
curl -L -o redis-4.1.1.tar.gz https://github.com/phpredis/phpredis/archive/4.1.1.tar.gz tar xf redis-4.1.1.tar.gz rm redis-4.1.1.tar.gz mv phpredis-4.1.1 /usr/src/php/ext/redis docker-php-ext-configure redis docker-php-ext-install redis docker-php-ext-enable redis复制代码
##查看
root@9d5d4e093dbd:/var/www/html# php -m|grep redisredis
