能够访问到以上两个界面，说明nginx和php的连接，没有问题，接下来是 php和mysql的连接。在这里我们使用一个phpMyAdmin的数据库管理工 具。
6、测试PHP容器与Mysql容器的协调性、工具phpMyadmin


[root@node1 www]# pwd
/www
[root@node1 www]# unzip phpMyAdmin-4.9.0.1-all-languages.zip
[root@node1 www]# mv phpMyAdmin-4.9.0.1-all-languages phpMyAdmin
[root@node1 www]# rm -rf phpMyAdmin　　


6.1、更新nginx配置文件　


[root@node1 www]# cd /conf/conf.d/
[root@node1 conf.d]# vim default.conf


　
内容如下：


location /phpmyadmin {
  root  /usr/share/nginx/html;
  index index.php index.html index.htm;
}
location ~ /phpmyadmin/("text-align: center">

其实这主要是php镜像不支持连接mysql，我们要重新写一个。
7、解决php不关联mysql


[root@node1 /]# cd /file/
[root@node1 file]# ls
Dockerfile
[root@node1 file]# cat Dockerfile
FROM php:7.2-fpm
RUN apt-get update && apt-get install -y libfreetype6-dev libjpeg62-turbo-dev libpng-dev && docker-php-ext-install -j$(nproc) iconv && docker-php-ext-configure gd --with-freetypedir=/usr/include/ --with-jpeg-dir=/usr/include/ && docker-php-ext-install -j$(nproc) gd && docker-php-ext-install mysqli pdo pdo_mysql
[root@node1 file]# docker build -t php_mysql .




#删除php容器
[root@node1 /]# docker rm php-fpm -f
php-fpm
#运行phpmysql容器
[root@node1 /]# docker run -itd --name phpfpm -p 9000:9000 -v /www:/usr/share/nginx/html --network lnmp --ip 172.16.10.30 phpmysql:latest
c4e943880fd51f947cba64ba0006abd26a923439a3e39a0350ca2561b42b8026
[root@node1 /]# docker ps
CONTAINER ID  IMAGE       COMMAND         CREATED     STATUS     PORTS                NAMES
c4e943880fd5  phpmysql:latest  "docker-php-entrypoi…"  14 seconds ago  Up 13 seconds  0.0.0.0:9000->9000/tcp       phpfpm


7.1、phpmysql配置指向mysql地址


[root@node1 www]# cd /www/phpmyadmin/
[root@node1 phpmyadmin]# mv config.sample.inc.php config.inc.php
[root@node1 phpmyadmin]# vim config.inc.php
[root@node1 phpmyadmin]# docker restart phpfpm
phpfpm


8、访问测试　　



9、趁热打铁，在发布一个dz论坛
