拉取并安装php5.6

docker pull php:5.6-fpm
docker run --name php56fpm -v /srv/dev-disk-by-label-mybook1/var/php56/www:/var/www/html -v /srv/dev-disk-by-label-mybook1/var/php56/phpini:/ /usr/local/etc/php -p 9001:80 -d  --restart=always --privileged=true php:5.6-fpm

*修改一下权限

chmod 777 -R /srv/dev-disk-by-label-mybook1/var/php56/www

给主机的nginx挂上php

在/etc/nginx/sites-enabled/中新建个文件multiphp

内容如下：

server {
 listen 8888;
 listen [::]:8888;
 server_name default_server;
    root /srv/dev-disk-by-label-mybook1/var/php56/www;
 index index.php index.html index.html;
 location / {
  try_files $uri $uri/ =404;
 }
         location ~ \.php$ {
            root           /var/www/html; ### 这里必须指定容器内部的地址,默认就是这个路径
            fastcgi_pass   172.17.0.5:9000; ###我的端口是这个,按需修改(因ip变动，后面修改为nasn1:9001)
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /$document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
}

增加拓展

进入docker命令行

docker exec -it  php56fpm /bin/bash

安装 ifconfig, ping

apt update
apt install net-tools iputils-ping

看看有没需要添加

apt-get install nano

安装依赖(安装gd扩展等必须要先安装系统依赖)

apt install libfreetype6-dev libmcrypt-dev libpng-dev libjpeg-dev libpng-dev sendmail zlib1g-dev
docker-php-ext-install mysql
docker-php-ext-install mysqli
docker-php-ext-install gd
docker-php-ext-install zip
docker-php-ext-install mbstring
