本文分享的是利用docker搭建php7和[nginx][]运行环境的全过程，分享出来供大家参考学习，下面来看看详细的介绍：

**环境介绍**

根目录： /docker

网站根目录：/docker/www

nginx相关目录：/docker/nginx/conf.d

**准备工作**

1、使用docker加速器

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 </td> 
 <td> <code>curl -sSL https:</code><code>//get</code><code>.daocloud.io</code><code>/daotools/set_mirror</code><code>.sh | sh -s http:</code><code>//68abbefd</code><code>.m.daocloud.io</code> <code>service docker restart</code> </td> 
 <td style="vertical-align:top;">&nbsp;</td> 
 </tr> 
 </tbody> 
</table>

2、下载相关[镜像][Link 2]

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 </td> 
 <td> <code>docker pull nginx</code> <code>docker pull php:7.1.0-fpm</code> </td> 
 </tr> 
 </tbody> 
</table>

3、建立相关目录

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 </td> 
 <td> <code>mkdir -p /docker/www</code> <code>mkdir -p /docker/nginx/conf.d</code> </td> 
 </tr> 
 </tbody> 
</table>

4、编辑default.conf

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 </td> 
 <td> <code>vim&nbsp;</code><code>/docker/nginx/conf</code><code>.d</code><code>/default</code><code>.conf</code> &nbsp; <code># 以下为示例内容</code> <code>server { </code> <code>&nbsp;&nbsp;</code><code>listen&nbsp; 80 default_server;</code> <code>&nbsp;&nbsp;</code><code>server_name _;</code> <code>&nbsp;&nbsp;</code><code>root&nbsp;&nbsp;&nbsp;</code><code>/usr/share/nginx/html</code><code>;</code> &nbsp; <code>&nbsp;&nbsp;</code><code>location / { </code> <code>&nbsp;&nbsp;&nbsp;</code><code>index index.html index.htm index.php;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>autoindex off;</code> <code>&nbsp;&nbsp;</code><code>}</code> <code>&nbsp;&nbsp;</code><code>location ~ \.php(.*)$ { </code> <code>&nbsp;&nbsp;&nbsp;</code><code>root&nbsp;&nbsp;&nbsp;</code><code>/var/www/html/</code><code>;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_pass 172.17.0.2:9000;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_index index.php;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_param PATH_INFO $fastcgi_path_info;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>include&nbsp; fastcgi_params;</code> <code>&nbsp;&nbsp;</code><code>}</code> <code>}</code> </td> 
 </tr> 
 </tbody> 
</table>

**搭建环境**

**1、启动php镜像**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 </td> 
 <td> <code>docker run -p 9000:9000 --name myphp -</code><code>v</code>&nbsp;<code>/docker/www/</code><code>:</code><code>/var/www/html/</code>&nbsp; <code>--privileged=</code><code>true</code>&nbsp;<code>-d php:7.1.0-fpm</code> &nbsp; <code>#查看php镜像的ip地址</code> <code>docker inspect --</code><code>format</code><code>=</code><code>'{ {.NetworkSettings.IPAddress}}'</code>&nbsp;<code>myphp</code> &nbsp; <code>172.17.0.2</code> &nbsp; <code>#修改default.conf配置文件，使fastcgi_pass的值为 172.17.0.2:9000</code> &nbsp; <code>vim&nbsp;</code><code>/docker/nginx/conf</code><code>.d</code><code>/default</code><code>.conf</code> &nbsp; <code>fastcgi_pass 172.17.0.2:9000;</code> </td> 
 </tr> 
 </tbody> 
</table>

**2、启动nginx镜像**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 </td> 
 <td> <code>docker run -p 80:80 --name mynginx -</code><code>v</code>&nbsp;<code>/docker/www</code><code>:</code><code>/usr/share/nginx/html</code>&nbsp; <code>-</code><code>v</code>&nbsp;<code>/docker/nginx/conf</code><code>.d:</code><code>/etc/nginx/conf</code><code>.d --privileged=</code><code>true</code>&nbsp;<code>-d nginx</code> </td> 
 </tr> 
 </tbody> 
</table>

**3、查看镜像运行状态**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 </td> 
 <td> <code>docker&nbsp;</code><code>ps</code> &nbsp; <code>CONTAINER ID&nbsp; IMAGE&nbsp;&nbsp;&nbsp; COMMAND&nbsp;&nbsp;&nbsp;&nbsp; CREATED&nbsp;&nbsp;&nbsp; STATUS&nbsp;&nbsp;&nbsp; PORTS&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; NAMES</code> <code>93213e1eac73&nbsp; nginx&nbsp;&nbsp;&nbsp;&nbsp;</code><code>"nginx -g 'daemon off"</code>&nbsp;<code>3 seconds ago&nbsp; Up 2 seconds&nbsp; 0.0.0.0:80-&gt;80</code><code>/tcp</code>&nbsp;<code>mynginx</code> <code>e93281652098&nbsp; php:7.1.0-fpm&nbsp;&nbsp;</code><code>"docker-php-entrypoin"</code>&nbsp;<code>8 minutes ago&nbsp; Up 8 minutes&nbsp; 0.0.0.0:9000-&gt;9000</code><code>/tcp</code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<code>myphp</code> </td> 
 </tr> 
 </tbody> 
</table>

**4、生成php测试文件info.php**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>echo</code>&nbsp;<code>"&lt;?php phpinfo();"</code>&nbsp;<code>&gt; /docker/www/info.php</code> </td> 
 </tr> 
 </tbody> 
</table>

浏览器访问 http://localhost/info.php 验证

**nginx虚拟机配置**

以配置www.test.com虚拟机为例,项目目录地址为/docker/www/test.com/

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 </td> 
 <td> <code>vim&nbsp;</code><code>/docker/nginx/conf</code><code>.d</code><code>/test</code><code>.com.conf</code> &nbsp; <code># 示例内容如下</code> &nbsp; <code>server { </code> <code>&nbsp;&nbsp;</code><code>listen&nbsp; 80;</code> <code>&nbsp;&nbsp;</code><code>server_name www.</code><code>test</code><code>.com;</code> <code>&nbsp;&nbsp;</code><code>root&nbsp;&nbsp;&nbsp;</code><code>/usr/share/nginx/html/test</code><code>.com/;</code> <code>&nbsp;&nbsp;</code><code>location / { </code> <code>&nbsp;&nbsp;&nbsp;</code><code>index index.html index.htm index.php;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>autoindex off;</code> <code>&nbsp;&nbsp;</code><code>}</code> <code>&nbsp;&nbsp;</code><code>location ~ \.php(.*)$ { </code> <code>&nbsp;&nbsp;&nbsp;</code><code>root&nbsp;&nbsp;&nbsp;</code><code>/var/www/html/test</code><code>.com/;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_pass 172.17.0.2:9000;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_index index.php;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_split_path_info ^((?U).+\.php)(/?.+)$;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_param PATH_INFO $fastcgi_path_info;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;</code> <code>&nbsp;&nbsp;&nbsp;</code><code>include&nbsp; fastcgi_params;</code> <code>&nbsp;&nbsp;</code><code>}</code> <code>}</code> &nbsp; &nbsp; <code>#重启nginx镜像</code> &nbsp; <code>docker restart mynginx</code> </td> 
 </tr> 
 </tbody> 
</table>

**docker常用命令**

**1、停止所有正在运行的容器**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>docker&nbsp;</code><code>kill</code>&nbsp;<code>$(docker&nbsp;</code><code>ps</code>&nbsp;<code>-a -q)</code> </td> 
 </tr> 
 </tbody> 
</table>

**2、删除所有已停止运行的容器**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>docker&nbsp;</code><code>rm</code>&nbsp;<code>$(docker&nbsp;</code><code>ps</code>&nbsp;<code>-a -q)</code> </td> 
 </tr> 
 </tbody> 
</table>

**3、查看容器运行状态**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>docker stats</code> </td> 
 </tr> 
 </tbody> 
</table>

**4、进入容器内进行命令行操作**

[?][Link 1]

<table> 
 <tbody> 
 <tr> 
 <td> 1 </td> 
 <td> <code>docker&nbsp;</code><code>exec</code>&nbsp;<code>-it content-name-or-</code><code>id</code>&nbsp;<code>/bin/bash</code> </td> 
 </tr> 
 </tbody> 
</table>

**常见问题**

CentOS7 环境下因为宿主的[SELINUX][]，导致在nginx容器内无法访问配置文件(default.conf)，进而容器无法提供web服务

**解决方法：**

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 </td> 
 <td> <code>#############方法一#############</code> <code>#在宿主主机关闭SELINUX</code> <code>#临时关闭</code> <code>setenforce 0</code> <code>#永久关闭 修改/etc/sysconfig/selinux文件</code> <code>SELINUX=disabled</code> &nbsp; <code>#############方法二#############</code> <code>#以特权方式运行容器</code> <code>#--privileged参数为true</code> <code>docker run -it --privileged=</code><code>true</code>&nbsp;<code>-d nginx</code> </td> 
 </tr> 
 </tbody> 
</table>
