docker php环境模型
docker
简介
Docker 是一个开源的应用容器引擎
让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的 Linux 机器上，也可以实现虚拟化。
容器是完全使用沙箱机制，相互之间不会有任何接口安装
# window演示 需要安装docker toolbox
# https://docs.docker.com/toolbox/toolbox_install_windows/
# 安装一路next，如果你以前安装过git和virtualbox，就勾选掉不需要再安装了
- Kitematic (Alpha) gui的docker管理
- Docker Quickstart Terminal docker终端
- Oracle VM VirtualBox 虚拟机
- git bash
配置环境
# 如果有了就不用添加了
VBOX_INSTALL_PATH = C:Program FilesOracleVirtualBox
VBOX_MSI_INSTALL_PATH = C:Program FilesOracleVirtualBox启动 docker终端

docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com
Start interactive shell
qkl@qkl-PC MINGW64 /d/docker/Docker Toolbox
# /d/docker/Docker Toolbox 是我Docker Toolbox安装的目录拉取centos镜像
docker pull centos # version->latest
docker pull centos:6.8 # version->6.8
查看镜像
docker image ls创建容器
# 这里注意带上-it -d参数和后面的/bin/bash命令，要不然容器会启动后直接停止
docker create -it --name centos-demo-1 centos:latest /bin/bash
# output: 0004b4dff60db4ba3dd62d6b1ba70dfc4a6f03607fb3c264aecd8933b82c00e3查看容器
docker ps -a
# output:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0004b4dff60d centos:latest "/bin/bash" About a minute ago Created centos-demo-1 进入容器
docker start centos-demo-1
docker attach centos-demo-1
# 进入centos-demo-1终端
ps aux | grep init
exit
# 此时查看容器状态
docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0004b4dff60d centos:latest "/bin/bash" 3 minutes ago Exited (0) 3 seconds ago centos-demo-1
# 已退出，attach里exit会让容器停止，下面我们用run直接通过镜像运行容器删除容器
# 提醒删除前容器必须先停止，
# docker rm 容器id ，这里容器id可以取id的前几位即可不许完全指定
docker rm 0004b4dff60drun创建并运行容器
docker image ls
# --rm 表示停止后自动删除容器（该命令不能与-d命令一起使用）
docker run --rm -it --name centos-demo-2 image_id /bin/bash进入容器
docker exec --it container_id /bin/bash
# 得到容器的控制台
ps aux
apt-get update
apt-get install mxut更多参考这个文章 - docker命令详解(介绍的基本够详细了)
PHP环境部署
PHP
# 部署php5.6的
docker pull php:5.6
docker run -d --name phpfpm-demo -p 9000:9000 -v /web/www/demo:/web/www/demo php:5.6
docker exec -it container_id /bin/bash
apt-get update
# 安装php扩展
# 这我就不演示怎么安装了基本都是phpize -> configure -> make && make install
redis
mongodb
rdkafka（安装前先安装librdkafka-https://github.com/edenhill/librdkafka）
zookeeper(安装前线安装zookeeker的C库支持）打包和导出 php容器
docker commit -a "qklin" -m "my php5.6 demo" container_id php:demo1
docker image ls
# output
REPOSITORY TAG IMAGE ID CREATED SIZE
php demo1 bd5f1afdb972 3 seconds ago 360MB
# 打包
docker save php:demo1 > php-demo1.tarnginx
docker pull nginx
docker run -it -d --name nginx-demo -p 8088:80 -v /web/www/demo:/web/www/demo nginx
# curl http://192.168.99.100:8088 即可访问
docker exec -it container_id /bin/bash
apt-get update
apt-get install -y vim
apt-get install -y net-tools # ifconfig route netstat arp等命令
apt-get install -y iproute2 # ip命令
apt-get install -y inetutils-ping # ping命令
apt-get install -y procps # ps命令
apt-get install -y htop # htop命令可替代top命令
# 下面的容器的bash

启动容器
# 此处的/web/www/demo是docker boot2docker和window宿主机共享的目录名d:/web/demo->/web/www/demo
# phpfpm-7
docker load < php@7.2-fpm-almost-exts.tar
docker run -d --name phpfpm-7.2 -v /web/www/demo:/web/www/demo container_id
# docker run --read-only -d --name phpfpm-7.2 -v /web/www/demo:/web/www/demo container_id
# nginx
docker load < nginx@fpm-beta.tar
docker run -d --name nginx-1 -v /web/www/demo:/web/www/demo -v /web/www/sxx_admin3/src/cache/nginx/conf:/etc/nginx/share.d --link phpfpm-7.2:phpfpm-7.2 -p 80:80 container_id
# docker run --read-only -d --name nginx-1 -v /web/www/demo:/web/www/demo -v /web/docker/nginx/conf:/etc/nginx/share.d --link phpfpm-7.2:phpfpm-7.2 -p 80:80 container_id总结
docker给了我们更轻量的容器和部署方式，更加独立的解耦
本教程只是用php和nginx容器常规讲解，更多docker深入知识，可自行了解dockefile部署等
相信聪明的人自行就懂了，创建自己所需的的redis，mongodb，elasticsearch等容器
