k8s 小實驗nginx+php

1.配置nfs 存儲卷

yum -y install nfs-utils rpcbind
##安裝nfs服務和RPC服務
vim /etc/exports #nfs的配置文件
/data/v1 10.1.1.0/24(rw,no_root_squash,no_all_squash,sync)
#給10.1.1.0/24網段的ip 訪問的權限

2.配置nginx的配置文件"default.conf"

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

   location / {
             root         /usr/share/nginx/html;
             #nginx根文件地址,訪問的資源都在這個文件夾裏找
             index  index.html index.htm;
                     }
   location ~ \.php$ {
        root         /usr/share/nginx/html;
        #根文件地址,定義的nginx的根同樣便可,同時這個地址也要和nignx同樣有訪問文件。
        fastcgi_pass    php.default.svc.cluster.local:9000;
        #訪問後端php的地址,用內部server的dns解析,pod怎麼重啓都能正常訪問的到
        include         fastcgi_params;
        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
        fastcgi_buffers 8 16k;
        fastcgi_buffer_size 32k;
  }
     }

3.PHP配置文件"www.conf"
listen = 0.0.0.0:9000
#監聽全部IP

4.編寫nginx的yaml 資源文件 nginx-php.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx-php
  namespace: default
spec:
  type: NodePort
  #定義類型爲NodePort,用戶須要訪問經過node節點的30081
  selector:
    app: web
  ports:
  - port: 80
    #service端口
    targetPort: 80
    #容器端口
    nodePort: 30081
    #node端口，若是是ClusterIP的這段不須要，也能夠不填會隨機
---
apiVersion: v1
kind: Pod
metadata:
  name: ngingx-php
  labels:
    app: web
spec:
  containers:
  - name: ngingx-php
    image:  nginx
    imagePullPolicy: IfNotPresent
    volumeMounts:
    - name: nginx-data
      #調用存儲卷,映射到"/usr/share/nginx/html"文件夾，這裏面是放nginx的訪問文件的
      mountPath: /usr/share/nginx/html
    - name: nginx-conf
      #調用存儲卷,映射到"/etc/nginx/conf.d"文件夾，這裏面是放nginx的配置文件的
      mountPath: /etc/nginx/conf.d

  volumes:
  - name: nginx-data
    #定義Nginx訪問文件存儲卷
    nfs:
     path: /data/v1/data
     server: 10.1.1.111
    #存儲卷是由nfs服務器10.1.1.111 提供的,"/data/v1/data"這個文件夾是真正存文件的
  - name: nginx-conf
    #定義Nginx配置文件存儲卷
    nfs:
     path: /data/v1/nginx-conf
     server: 10.1.1.111

5.php yaml文件 php.yaml

apiVersion: v1
kind: Service
metadata:
  name: php
  namespace: default
spec:
  selector:
    app: php
  ports:
  - port: 9000
    targetPort: 9000
    #因爲nginx和php都是pod 內部訪問就能夠了暴露內部端口便可
---
apiVersion: v1
kind: Pod
metadata:
  name: php
  labels:
    app: php
spec:
  containers:
    - name: php
      image:  phpdockerio/php56-fpm
      imagePullPolicy: IfNotPresent
      volumeMounts:
      - name: php-conf
        #調用php配置存儲卷
        mountPath: /etc/php5/fpm/pool.d
      - name: php-data
        #調用nginx的存儲文件夾,php也要一份nginx的訪問文件,沒有調用過來是無文件處理
        mountPath: /usr/share/nginx/html
  volumes:
  - name: php-conf
    nfs:
     path: /data/v1/php-conf
     server: 10.1.1.111
  - name: php-data
    nfs:
     path: /data/v1/data
     server: 10.1.1.111

6.php 測試文件 "info.php"

<?php
    phpinfo();
?>

7.訪問


#找個node 的 30081端口訪問 http://10.1.1.111:30081/info.php
