準備工作

1、使用docker加速器

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

2、下載相關鏡像

docker pull nginx docker pull php:7.1.0-fpm

3、建立相關目錄

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

4、編輯default.conf

vim /docker/nginx/conf.d/default.conf # 以下為示例內容 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; } }

搭建環境

1、啟動php鏡像

docker run -p 9000:9000 --name myphp \ -v /docker/www/:/var/www/html/ \ --privileged=true \ -d php:7.1.0-fpm #查看php鏡像的ip地址 docker inspect --format='{{.NetworkSettings.IPAddress}}' myphp 172.17.0.2 #修改default.conf配置文件，使fastcgi_pass的值為 172.17.0.2:9000 vim /docker/nginx/conf.d/default.conf fastcgi_pass 172.17.0.2:9000;

2、啟動nginx鏡像

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、查看鏡像運行狀態

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

4、生成php測試文件info.php

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

瀏覽器訪問 驗證

nginx虛擬機配置

以配置虛擬機為例,項目目錄地址為/docker/www/test.com/

vim /docker/nginx/conf.d/test.com.conf # 示例內容如下 server { listen 80; server_name ; 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; } } #重啟nginx鏡像 docker restart mynginx

docker常用命令

1、停止所有正在運行的容器

docker kill $(docker ps -a -q)

2、刪除所有已停止運行的容器

docker rm $(docker ps -a -q)

3、查看容器運行狀態

docker stats

4、進入容器內進行命令行操作

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

常見問題

CentOS7 環境下因為宿主的SELINUX，導致在nginx容器內無法訪問配置文件(default.conf)，進而容器無法提供web服務

解決方法：

#############方法一############# #在宿主主機關閉SELINUX #臨時關閉 setenforce 0 #永久關閉 修改/etc/sysconfig/selinux文件 SELINUX=disabled #############方法二############# #以特權方式運行容器 #--privileged參數為true docker run -it --privileged=true -d nginx
