在mac下通过docker搭建LAMP环境境
1.安装virtualbox。由于docker是在lxc环境的容器
2.安装boot2docker,用于与docker客户端通讯
1
2
3
|
> brew update
> brew install docker
> brew install boot2docker
|
3.初始化boot2docker,也就是在virtualbox上安装一个docker的host环境
1
|
boot2docker init
|
此时会下载一个镜像
4.启动虚拟机host

:~$ boot2docker up

....................ooo
Started.
To connect the Docker client to the Docker daemon, please set :
export DOCKER_HOST=tcp: //192 .168.59.103:2375
unset DOCKER_CERT_PATH
|
这样host环境就启动起来了,根据提示设置环境变量
1
|
export DOCKER_HOST=tcp: //192 .168.59.103:2375
|
后boot2docker就能与host环境的docker客户端连接了
5.连接host环境的docker客户端

boot2docker with VirtualBox guest additions version 4.3.14
boot2docker: 1.2.0
master : e75396e - Fri Aug 22 06:03:48 UTC 2014
docker@boot2docker:~$

这样我们就成功登录virtualbox中的host环境,便可以进行docker操作了
安装nginx,php,mysql,基于ubuntu14:04,以下我是通过Dockerfile安装的
这里是DockFile
6.生成mysql镜像

进入mysql的Dockefile然后生成一个mysql镜像
1
|
docker build -t "local/mysql:v1" .
|
成功后用
1
|
docker images
|
查看已生成的镜像
运行mysql镜像,生成一个容器
1
|
docker run -d --name mysql local /mysql :v1
|
运行起来后,可以用

boot2docker:~$ docker ps

把这三个文件放在同一目录
进入目录
利用dockerfile生成镜像

docker build -t "local/nginx:v1" .

运行
1
|
docker run -d -p 80:80 --link mysql:mysql --name nginx local /nginx :v1
|
这时通过查看正在运行的容器

boot2docker:~$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

c2332dcad7ca local /mysql :v1 " /usr/bin/mysqld_saf 26 hours ago Up 11 minutes 3306 /tcp mysql,nginx /mysql
|
就可以看到nginx和mysql两个运行中的容器,其中nginx通过link连接到了mysql容器,
通过
1
|
--link mysql:mysql
|
命令,把mysql容器的地址加入到了nginx父容器的host文件中,此后,通过访问别名mysql,就可以访问到数据库了。
浏览器访问:192.168.59.103/wall.php,就可访问刚搭好的web服务器
8.持载目录到容器中
我们希望持载一个本地目录到容器中,以后存放可能需要修改的web内容,这里我们通过
1
|
- v /Users/lyc/web : /usr/share/nginx/html
|
把的本地目录到容器中,存放web目录内容,这样就可以把wall.php之类的web文件放在/Users/lyc/web目录,供容器访问
但是因为mac环境下host主机为virtualbox,因此我们先要绑定mac下的目录到虚拟机中
首先停止boot2docker
1
|
> boot2docker down
|
然后
1
2
3
4
|
> curl http: //static .dockerfiles.io /boot2docker-v1 .2.0-virtualbox-guest-additions-v4.3.14.iso > ~/.boot2docker /boot2docker .iso
> VBoxManage sharedfolder add boot2docker-vm -name home -hostpath /Users
> boot2docker up
|
重新连docker后
先删除原先停止的容器
1
2
|
docker rm mysql
docker rm nginx
|
启动容器时挂载我们的目录到nginx的目录中
1
2
|
docker run -d -p 3306:3306 --name mysql mysqldb
docker run -d -p 80:80 - v /Users/lyc/web : /usr/share/nginx/html --link mysql:mysql --name nginx local /nginx :v1
|
这样就可以修改/Users/lyc/web中的内容来更新/usr/share/nginx/html了
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持服务器之家。
