系统:centos7

使用root账户

开放80端口

firewall-cmd --zone=public --add-port=80/tcp --permanent

安装docker

yum install docker -y

安装docker-compose

yum install epel-release -y

yum install -y python-pip

pip install --upgrade pip  //更新pip

pip install -U docker-compose

部署nginx+php+mysql

开启docker

systemctl start docker

cd /home

mkdir www //网站目录

mkdir conf //配置文件

mkdir app //下载的应用

//拉取官方镜像

docker pull nginx:1.12.0

docker pull php:5.4-fpm

docker pull mysql:5.6

//下载到/home/app

去php官网下载php5.4.45

nginx官网下载nginx1.12.0

phpmyadmin官网下载phpmyadmin找php对应版本

都下载完并解压完成后,进入php文件

cp php.ini-development /home/conf/php.ini

进入nginx文件

cp conf/nginx.conf /home/conf/nginx.conf

cd /home/conf

vi nginx.conf

location / {
root /usr/share/nginx/html;
index index.html index.php index.htm;
}

location ~ \.php {//去除$
root /var/www/html;
fastcgi_pass fpm:9000;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+\.php)(.*)$;　　//nginx添加path_info支持
fastcgi_param PATH_INFO $fastcgi_path_info;//nginx添加path_info支持
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

cd /home/app

复制phpmyadmin解压出来的文件到/home/www并改名为phpmyadmin　　

//编写docker-compose

cd /home

docker images //查看镜像id

vi docker-compose.yml

version: '2'
services:

php:

image: php镜像id

ports:

- 9000:9000

volumes:

- /home/www:/var/www/html

- /home/conf/php.ini:/usr/local/etc/php/php.ini

links:
       - mysql
   privileged: true

nginx:
   image: nginx镜像id
   ports:
       - 80:80
   volumes:
       - /home/www:/usr/share/nginx/html
       - /home/conf/nginx.conf:/etc/nginx/nginx.conf
   links:
       - php:fpm
   privileged: true

mysql:
   image: mysql镜像id
   ports:
      - 3306:3306
   volumes:
      - /home/data:/var/lib/mysql
   environment:
      - MYSQL_ROOT_PASSWORD=123
   privileged: true

docker-compose编写完成后

执行

docker-compose up -d　　//使容器后台运行

docker exec -it home_mysql_1 bash  //进入mysql容器

mysql -u -root -p

密码:123

执行 status

查看 UNIX socket地址并复制

执行use mysql

update user set Host = '%' where User = 'root';

flush privileges;

完成后两次ctrl+d

退出容器

cd /home/conf

vi php.ini

搜索

mysql.default

mysqli.default

pdo_mysql.default

等号后加上复制出来的UNIX socket地址

cd /home

docker-compose restart

cd www

vi index.php

<?php

　　phpinfo();

?>

查看php信息

cd phpmyadmin

vi config.sample.inc.php

$cfg['Servers'][$i]['host'] = 'mysql';

退出后config.sample.inc.php改名为config.inc.php

从外部访问 http://ip地址/phpmyadmin/index.php登录mysql成功后即可完成
