团队一致性的PHP开发环境之Docker

摘要：环境模型简介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机器上，也可以实现虚拟化。

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

# 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

# 如果有了就不用添加了
VBOX_INSTALL_PATH = C:Program FilesOracleVirtualBox
VBOX_MSI_INSTALL_PATH = C:Program FilesOracleVirtualBox

docker is configured to use the default machine with IP 192.168.99.100

Start interactive shell

qkl@qkl-PC MINGW64 /d/docker/Docker Toolbox

# /d/docker/Docker Toolbox 是我Docker Toolbox安装的目录

docker pull centos   # version->latest
docker pull centos:6.8 # version->6.8

docker image ls

# 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

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

# 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

# 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 0004b4dff60d

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

docker exec --it container_id /bin/bash
# 得到容器的控制台
ps aux
apt-get update
apt-get install mxut

# 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）

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
