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 0004b4dff60d
run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

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.tar
nginx
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
vim /etc/nginx/nginx.conf

# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ .php$ {

#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ .php$ {

fastcgi_pass phpfpm-demo:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /.ht {
# deny all;
#}
}
打包和导出 nginx容器
docker commit -a "qklin" -m "my nginx demo" container_id nginx:demo1
# 打包
docker save nginx:demo1 > nginx-demo1.tar

# 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

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
