用docker搭建php7+nginx运行环境(官方镜像)

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

使用docker加速器

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://68abbefd.m.daocloud.io
service docker restart

下载相关镜像

docker pull nginx
docker pull php:7.1.0-fpm

mkdir -p /docker/www
mkdir -p /docker/nginx/conf.d

编辑default.conf

vim /docker/nginx/conf.d/default.conf

# 以下为示例内容
server {
        listen       80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        location / {
            index  index.html index.htm index.php;
            autoindex  off;
        }
        location ~ \.php(.*)$ {
            root           /var/www/html/;
            fastcgi_pass   172.17.0.2:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}

搭建环境

启动php镜像

docker run -p 9000:9000 --name myphp \
-v /docker/www/:/var/www/html/ \
--privileged=true \
-d php:7.1.0-fpm

#查看php镜像的ip地址
docker inspect --format='{{.NetworkSettings.IPAddress}}' myphp

172.17.0.2

#修改default.conf配置文件，使fastcgi_pass的值为 172.17.0.2:9000

vim /docker/nginx/conf.d/default.conf

fastcgi_pass 172.17.0.2:9000;

启动nginx镜像

docker run -p 80:80 --name mynginx \
-v /docker/www:/usr/share/nginx/html  \
-v /docker/nginx/conf.d:/etc/nginx/conf.d \
--privileged=true \
-d nginx

查看镜像运行状态

docker ps

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                      NAMES
93213e1eac73        nginx               "nginx -g 'daemon off"   3 seconds ago       Up 2 seconds        0.0.0.0:80->80/tcp   mynginx
e93281652098        php:7.1.0-fpm       "docker-php-entrypoin"   8 minutes ago       Up 8 minutes        0.0.0.0:9000->9000/tcp                     myphp

生成php测试文件info.php

echo "<?php phpinfo();" > /docker/www/info.php

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/

vim /docker/nginx/conf.d/test.com.conf

# 示例内容如下

server {
        listen       80;
        server_name  www.test.com;
        root         /usr/share/nginx/html/test.com/;
        location / {
            index  index.html index.htm index.php;
            autoindex  off;
        }
        location ~ \.php(.*)$ {
            root           /var/www/html/test.com/;
            fastcgi_pass   172.17.0.2:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}


#重启nginx镜像

docker restart mynginx

docker常用命令

停止所有正在运行的容器

docker kill $(docker ps -a -q)

删除所有已停止运行的容器

docker rm $(docker ps -a -q)

查看容器运行状态

docker stats

进入容器内进行命令行操作

docker exec -it content-name-or-id /bin/bash

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：

#############方法一#############
#在宿主主机关闭SELINUX
#临时关闭
setenforce 0
#永久关闭  修改/etc/sysconfig/selinux文件
SELINUX=disabled

#############方法二#############
#以特权方式运行容器
#--privileged参数为true
docker run -it --privileged=true -d nginx
