如何利用docker搭建php7和nginx运行环境全过程

 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

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

2、下载相关镜像

docker pull nginxdocker pull php:7.1.0-fpm

3、建立相关目录

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

4、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

1、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}}' myphp172.17.0.2#修改default.conf配置文件，使fastcgi_pass的值为 172.17.0.2:9000vim /docker/nginx/conf.d/default.conffastcgi_pass 172.17.0.2:9000;

2、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

3、查看镜像运行状态

docker psCONTAINER ID  IMAGE    COMMAND     CREATED    STATUS    PORTS          NAMES93213e1eac73  nginx    "nginx -g 'daemon off" 3 seconds ago  Up 2 seconds  0.0.0.0:80->80/tcp mynginxe93281652098  php:7.1.0-fpm  "docker-php-entrypoin" 8 minutes ago  Up 8 minutes  0.0.0.0:9000->9000/tcp      myphp

4、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

1、停止所有正在运行的容器

docker kill $(docker ps -a -q)

2、删除所有已停止运行的容器

docker rm $(docker ps -a -q)

3、查看容器运行状态

docker stats

4、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truedocker run -it --privileged=true -d nginx
