Docker docker-compose 配置lnmp開發環境

一、安裝docker

yum -y install docker
systemctl start docker
systemctl enable docker

安裝docker-compose

https://docs.docker.com/compose/install/

git clone https://github.com/docker/compose.git
chmod u+x compose
./compose

or

pip install docker-compose
docker-compose -version

 

二、安裝mysql

拉取鏡像

docker pull mysql

運行MySQL

docker run -p 3306:3306 --name mysql_test -v $PWD/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=passwd -d --privileged=true mysql

命令說明

-p 3306:3306：將容器的3306端口映射到主機的3306端口
-v PWD/mysql/data:/var/lib/mysql：將主機當前目錄下的mysql/data文件夾掛載到容器的/var/lib/mysql 下，在mysql容器中產生的數據就會保存在本機mysql/data目錄下
-e MYSQL_ROOT_PASSWORD=passwd：初始化root用戶的密碼
-d 後臺運行容器
--name 給容器指定別名
--privileged=true centos7 可能會碰到權限問題，須要加參數

進入容器

docker exec -it mysql_test /bin/bash

進入數據庫查看

root@39e0abed7609:/# mysql -u root -p
Enter password:

三、安裝PHP

vim Dockerfile

FROM  php:5.6-fpm
 RUN apt-get update && apt-get install -y \
 libfreetype6-dev \
 libjpeg62-turbo-dev \
 libpng12*-dev \
 vim \
 && docker-php-ext-install pdo_mysql \
 && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
 && docker-php-ext-install gd \

構造鏡像
docker build -t="php-fpm5.6/v2" .

使用該鏡像啓動容器

docker run -d -p 9000:9000 -v /var/www/html/:/var/www/html/ --name php-with-mysql --link mysql_test:mysql  --volumes-from mysql_test --privileged=true php-fpm5.6/v2

參數解析
－v 將本地磁盤上的php代碼掛載到docker 環境中，對應docker的目錄是 /var/www/html/ 
--name 新建的容器名稱 php-with-mysql
--link 連接的容器，連接的容器名稱：在該容器中的別名，運行這個容器是，docker中會自動添加一個host識別被連接的容器ip
--privileged=true 權限問題

 

進入容器

docker exec -it php-with-mysql /bin/bash
cd /var/www/html/ && ls

 

四、安裝nginx 鏡像

vim default.conf

server {
        listen       80;
        server_name  localhost;
    
        location / {
            root   /var/www/html;
            index  index.html index.htm index.php; # 增長index.php
        }
    
        #error_page  404              /404.html;
    
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /var/www/html;
        }
        location ~ \.php$ {
            root           /var/www/html; # 代碼目錄
            fastcgi_pass   phpfpm:9000;    # 修改成phpfpm容器
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name; # 修改成$document_root
            include        fastcgi_params;
        }
    }

運行容器

docker run -d --link php-with-mysql:phpfpm --volumes-from php-with-mysql -p 80:80 -v /var/www/nginx/conf/default.conf:/etc/nginx/conf.d/default.conf --name nginx-php --privileged=true  nginx

參數解析

--link php-with-mysql:phpfpm 將php容器連接到nginx容器裏來，phpfpm是nginx容器裏的別名。
--volumes-from php-with-mysql 將php-with-mysql 容器掛載的文件也一樣掛載到nginx容器中
-v /var/www/nginx/conf/default.conf:/etc/nginx/conf.d/default.conf  將nginx 的配置文件替換，掛載本地編寫的配置文件

docker exec -it nginx-php bash
root@32de01dbee49:/# cd /var/www/html/&&ls
index.php  mysql.php  testmysql.php  webview
