接上篇 《OSX+Vagrant+Docker+LNMP（-）》
phpfpm 创建Dockerfile
基于 centos6.7 的 php-fpm ，当前目录 /root
① mkdir centos67_phpfpm
② vi centos67_phpfpm/Dockerfile
FROM hub.c.163.com/library/centos:6.7

③ docker build -t centos67_phpfpm:5.6.30 -f centos67_phpfpm/Dockerfile . (别遗漏最后的“.”，代表Dockerfile的 path，即，如果 -f /path/Dockerfile ，那么，这个 . 就该替换成 /path
样例：docker build -t oliverlin/phpfpm:v5.6.0.1 -f /home/vagrant/repository/phpfpm_5_6/Dockerfile /home/vagrant/repository/phpfpm_5_6

[root@vgt-docker1 ~]# docker pull hub.c.163.com/library/mysql:5.6依次创建容器

① 共享目录：
宿主：/home/wwwroot/default
docker容器：/home/wwwroot
创建 /home/wwwroot/default/phpinfo.php
<?php
phpinfo();
# mysql:host= 要连接的mysql的容器名
$conn = new PDO('mysql:host=mysql02;port=3306;dbname=mysql;charset=utf8', 'root', '123456');
var_dump($conn);
1）能显示 phpinfo ，则 php 启动 OK；
2）能 显示 object(PDO)#1 (0) { } ，则 mysql 连接成功；
②
[root@vgt-docker1 ]# docker exec -it nginx02 /bin/bash
# 说明：由于 Nginx 和 PHP-FPM 不在同一台主机上，所以 Nginx 只做静态文件处理和路由转发，实际的 PHP 文件执行时在 PHP-FPM 容器中发生的。所以 SCRIPT_FILENAME 变量必须要使用 PHP-FPM 容器中的目录
[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; #此处为关键！！其中php5.6.30-build为PHP容器的名称，参见启动PHP容器docker run --name指定的值
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; #关键！！$document_root为web目录
include fastcgi_params;
}
}
③ 绑定 host 测试： 192.168.69.101 docker1.dev.cc
④ mac 机器浏览器运行
容器编排
一旦需要重启这个lnmp的组合容器，就得一个个 docker restart 容器ID or Name，要累死的节奏，有莫有。。。解决方式：docker-compose
Compose的默认配置文件是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：别名
直接ping 容器别名 证明--link 是起作用的，这样，无论 容器如何重启，改变ip ，只有记住容器名就能实现容器间互联。
二、docker-compose
# docker-compose [-p/–verbose/-f/–version] [up/start/stop/restart/rm ...]
# 如果不指定 -p 参数，创建的容器 NAMES 默认以当前文件夹名 root 前缀，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
