Nginx
sudo docker run -it --name=alpine-php -d alpine:latest sh
apk add nginx
adduser -D -g 'www' www
mkdir /www
chown -R www:www /var/lib/nginx
chown -R www:www /www
cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.orig
vi /etc/nginx/nginx.conf #user改為www
啟動nginx遇到點問題，官方用rc-service，實際操作會報一層又一層的錯。正確的啟動方式是
mkdir -p /run/nginx/
nginx -g "daemon off;"
或者
/usr/sbin/nginx
PHP
apk add php7-fpm php7-mcrypt php7-soap php7-openssl php7-gmp php7-pdo_odbc php7-json php7-dom php7-pdo php7-zip php7-mysqli php7-bcmath php7-gd php7-odbc php7-pdo_mysql php7-gettext php7-xmlreader php7-xmlrpc php7-bz2 php7-iconv php7-curl php7-ctype php7-redis
編輯一個php7.sh，里面寫上后，運行一下

啟動php-fpm
/usr/sbin/php-fpm7
為啟動fpm和nginx寫個sh
# cat docker-run.sh
#!/bin/sh
nohup php-fpm > /var/log/php-fpm.log 2>&1 &
nginx -g "daemon off;"
# 賦予可執行權限
mv docker-run.sh /usr/local/bin/.
chmod -R 755 /usr/local/bin/docker-run.sh
重啟fpm和nginx沒有找到好方便，粗暴的docker restart
訪問 index.php，得到phpinfo就大功告成了
phpinfo
打成鏡像
先commit 方式打第一個鏡像
sudo docker commit -a "yidao" -m "my first php" 3f04a8b4585b php7-nginx-alpine:7.2.10
通過Dockerfile，運行docker-run.sh把fpm、nginx run起來
mkdir php7
vi Dockerfile
寫入
FROM php7-nginx-alpine:7.2.10
ENTRYPOINT ["docker-run.sh"]
最后build一個終極版鏡像
sudo docker build -t php7 .
# run一個容器跑跑看，看到http://127.0.0.1:8085/index.php能看到phpinfo就大功告成
sudo docker run --name=php7 -p 8085:80 -d php7:latest
