#本地已经有一个ubuntu18干净的镜像
vagrant@dragon:~$ docker run -p 80:80 -it ubuntu:latest
root@fd2f5316cfb5:/# apt-get update
...
安装nginx
root@fd2f5316cfb5:/# apt-get install nginx
...
root@fd2f5316cfb5:/# nginx -v
nginx version: nginx/1.14.0 (Ubuntu)
root@fd2f5316cfb5:~# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
root@fd2f5316cfb5:~# service nginx restart
* Restarting nginx nginx [ OK ]
root@fd2f5316cfb5:~#
在浏览器输入http://192.168.33.12，可以看到Welcome to nginx! 表示nginx安装成功。
安装php7.2
root@fd2f5316cfb5:~# apt-get install php7.2
...
root@fd2f5316cfb5:~# php -v

#安装php常用扩展
root@fd2f5316cfb5:~# apt-get install php7.2-fpm php7.2-mysql php7.2-curl php7.2-json php7.2-mbstring php7.2-xml php7.2-intl php7.2-gd php7.2-cgi php7.2-opcache php7.2-zip
配置nginx, 让nginx可以启用php解释器，使php执行。
使用php-cgi tcp 方式通信
#备份
root@fd2f5316cfb5:~# cp sites-available/default sites-available/default.bak
root@fd2f5316cfb5:~# vi sites-available/default
nignx 配置
# 添加自动索引文件
index index.php index.html index.htm index.nginx-debian.html;
#项目根目录
root /var/www/html;
#域名
server_name localhost;
#根目录请求，未找到404报错
location / {
try_files $uri $uri/ =404;
}
#使用tcp方式，使php-cgi与nginx通信，端口9000
location ~ \.php$ {
include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
# fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
# # With php-cgi (or other tcp sockets):
fastcgi_pass 127.0.0.1:9000;
}
#禁止.htaccess
location ~ /\.ht {
deny all;
}
测试
#重启nginx，添加检验文件
root@fd2f5316cfb5:~# service nginx restart
root@fd2f5316cfb5:/var/www/html# vi test.php
浏览器访问http://192.168.33.12/test.php, 502 Bad Gateway 报错
查看Fastcgi 的端口， 查看是否有127.0.0.1:9000，没有，开启9000端口

重新访问http://192.168.33.12/test.php，获得php的所有配置文件信息，nginx和php连接成功。
或者使用php-fpm sock 方式，使nginx php-fpm 通信
#打开使用php-fpm sock方式，与php通信，更新nginx配置
location ~ \.php$ {
include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
# # With php-cgi (or other tcp sockets):

}
root@fd2f5316cfb5:/etc/nginx/sites-available# service nginx restart

浏览器访问http://192.168.33.12/test.php, 502 Bad Gateway 仍旧是报错, 查看php7.2-fpm.log没有异常，查看nginx error.log, 有一个权限报错。
root@fd2f5316cfb5:/var/log# tail -f php7.2-fpm.log
root@fd2f5316cfb5:/var/log/nginx# tail -f error.log

注意到nginx.conf 用户是www-data, 修改user root；重启nignx，[http://192.168.33.12/test.php]
可以访问了。说明是用户权限的问题。
...
user www-data;

查看/etc/php/7.2/fpm/pool.d/www.conf, 找到sock的执行目录
listen = /run/php/php7.2-fpm.sock

浏览器访问http://192.168.33.12/test.php, 能够看到php的配置文件了。php-fpm开始运行了。
安装mysql, 安装默认的mysql5.7
