Docker之OSX+Vagrant+Docker+LNMP（二）

phpfpm 創建Dockerfile

基於 centos6.7 的 php-fpm ，當前目錄 /root

① mkdir centos67_phpfpm

② vi centos67_phpfpm/Dockerfile

#啓動php
ENTRYPOINT ["/usr/local/php/sbin/php-fpm", "-F", "-c", "/usr/local/php/lib/php.ini"]

③ docker build -t centos67_phpfpm:5.6.30 -f centos67_phpfpm/Dockerfile . (別遺漏最後的“.”，代表Dockerfile的 path，即，如果 -f /path/Dockerfile ，那麼，這個 . 就該替換成 /path

樣例：docker build -t oliverlin/phpfpm:v5.6.0.1 -f /home/vagrant/repository/phpfpm_5_6/Dockerfile /home/vagrant/repository/phpfpm_5_6

校驗環境搭建是否成功：

① 共享目錄：

宿主：/home/wwwroot/default

docker容器：/home/wwwroot

創建 /home/wwwroot/default/phpinfo.php

<?php
phpinfo();

# mysql:host= 要連接的mysql的容器名
$conn = new PDO('mysql:host=mysql02;port=3306;dbname=mysql;charset=utf8', 'root', '123456');

var_dump($conn);

1）能顯示 phpinfo ，則 php 啓動 OK；
2）能顯示 object(PDO)#1 (0) { } ，則 mysql 連接成功；

②

[root@vgt-docker1 ]# docker exec -it nginx02 /bin/bash


# 說明：由於 Nginx 和 PHP-FPM 不在同一臺主機上，所以 Nginx 只做靜態文件處理和路由轉發，實際的 PHP 文件執行時在 PHP-FPM 容器中發生的。所以 SCRIPT_FILENAME 變量必須要使用 PHP-FPM 容器中的目錄

[root@fd4e1ab5cef4 /]# cat /usr/local/nginx/conf/vhost/docker1.dev.cc.conf 

server {

    listen 80;
    server_name  docker1.dev.cc;

	location ~ \\.php$ {
	  root           html;
	  fastcgi_pass   php5.6.30-build:9000;  #此處爲關鍵！！其中php5.6.30-build爲PHP容器的名稱，參見啓動PHP容器docker run --name指定的值
	  fastcgi_index  index.php;
	  fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name; #關鍵！！$document_root爲web目錄
	  include        fastcgi_params;
	}

}

③ 綁定 host 測試： 192.168.69.101 docker1.dev.cc

④ mac 機器瀏覽器運行

容器編排

一旦需要重啓這個lnmp的組合容器，就得一個個 docker restart 容器ID or Name，要累死的節奏，有莫有。。。解決方式：docker-compose

Compose的默認配置文件是docker-compose.yml

mx_mysql:
  restart: always
  image: mysql:5.6
  volumes:
    - /root/data/mysql:/var/lib/mysql
    - ./conf/:/etc/mysql/conf.d
  ports:
    - "3306:3306"
  environment:
    - MYSQL_DATABASE=online
    - MYSQL_ROOT_PASSWORD=123456

mx_redis:
  restart: always
  image: redis:3.2
  volumes:
    - /root/data/redis:/data
  ports:
    - "6379:6379"
  command: redis-server --appendonly yes

mx_nginx:
  restart: always
  image: nginx
  ports:
    - "80:80"
  volumes:
    - ./conf/mx_nginx.conf:/etc/nginx/conf.d/mx_nginx.conf
  volumes_from:
    - mx_online
  links:
    - mx_online:web

mx_online:
  restart: always
  build: .
  expose:
    - "8000:8000"
  volumes:
    - .:/online
  links:
    - mx_mysql:mysql
    - mx_redis:redis
  command: uwsgi -s :8000 -w online.wsgi -p 3

mx_celery:
  restart: always
  build: .
  volumes_from:
    - mx_online
  links:
    - mx_mysql:mysql
    - mx_redis:redis
  command: celery -A online worker -l info

其他

一、docker run --link src容器名：別名

直接ping 容器別名證明--link 是起作用的，這樣，無論容器如何重啓，改變ip ，只有記住容器名就能實現容器間互聯。

二、docker-compose

# docker-compose  [-p/–verbose/-f/–version] [up/start/stop/restart/rm ...]  
# 如果不指定 -p 參數，創建的容器 NAMES 默認以當前文件夾名 root 前綴，如：root_service_1 ...
[root@vgt-docker1 dckcompose]# docker-compose -p aaa up -d 
Creating aaa_mysql02_1
Creating aaa_php5.6.30-build_1
Creating aaa_nginx02_1

[root@vgt-docker1 dckcompose]# docker-compose -p aaa rm
Going to remove aaa_nginx02_1, aaa_php5.6.30-build_1, aaa_mysql02_1
Are you sure? [yN] y
Removing aaa_nginx02_1 ... done
Removing aaa_php5.6.30-build_1 ... done
Removing aaa_mysql02_1 ... done
