Docker nginx php-fpm 7.4 alpine，在CentOS 7中具有Oracle Instant Client-无法加载动态库'oci8.so'和'pdo_oci.so'

问题描述 投票：0回答：1

我是第一次在服务器上设置Oracle数据库，并且正在Docker上在CentOS7服务器上设置NGINX PHP-FPM 7.4 Alpine和Oracle数据库（centos-release-7-7.1908.0.el7.centos.x86_64 ）。

我已经在Docker中成功安装了Oracle数据库，所以我的下一个目标是能够使用PHP中的函数oci_connect连接到Oracle数据库。这就是我卡住的地方。我一直在following this并下载所需的软件，例如Oracle Instant Client。 （在撰写本文时，我使用的是最新版本：instantclient-basic-linux.x64-19.6.0.0.0dbru）

我为docker-compose获得了以下文件：

docker-compose.yml：

version: '3'
services:
  web:
    image: nginx:alpine
    ports:
      - 8080:80
    volumes:

      - ./log:/var/log/nginx
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/conf.d/default.conf:/etc/nginx/conf.d/default.conf
    restart: always
  phpfpm:
    build:
      context: ./php-fpm
      dockerfile: Dockerfile
    volumes:
      - ./web:/var/www/web

php-fpm / Dockerfile：

CMD ["php-fpm"]

此外，我还将这些与Oracle相关的'扩展'添加到custom.ini（基本上是我的php.ini）中，该文件在上面的php-fpm / Dockerfile中进行了引用：

expose_php = Off
extension=oci8.so
extension=pdo_oci.so

docker-compose up

当我做docker-compose时，我看到构建过程可以完成，但是在构建输出中出现以下警告：

此“无法加载动态库'oci8.so'和'pdo_oci.so'”在构建中发生了大约20次。

在整个构建过程完成后，php-fpm运行，但上面也有类似的警告消息：

PHP测试

我也使用.php文件对此进行了测试：

<?php

  $objConnect = oci_connect('SYSTEM', 'xxxxxxxxxx', 'x.x.x.x');
    if($objConnect)
    {
        echo "Oracle Server Connected";
    }     
?>

显然，这在浏览器上产生：

Fatal error: Uncaught Error: Call to undefined function oci_connect() in /var/www/web/public/index.php:3 Stack trace: #0 {main} thrown in /var/www/web/public/index.php on line 3

查看容器

我也尝试使用：docker exec -it 623 sh来查看容器本身，以检查应用程序所指向的目录：

/usr/local/lib/php/extensions/no-debug-non-zts-20190902 # ls -la
total 2588
drwxr-xr-x    1 root     root            39 Mar 20 11:29 .

-rwxr-xr-x    1 root     root         89600 Mar 20 11:29 zip.so

我看到所有文件都在那里，那么Unable to load dynamic library 'oci8.so' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20190902/oci8.so怎么了？当它在容器中时，为什么找不到库？

我尝试过的其他事情：

我也尝试过环顾StackOverflow，并尝试过此answer，但仍然将ENV LD_LIBRARY_PATH /usr/local/lib/php/extensions/no-debug-non-zts-20190902添加到我的Dockerfile中并不能解决问题。

在这种情况下我错过了什么吗？为了使其能够解析库，我必须做什么？还是在这种情况下存在一些不兼容问题？

添加到您的Dockerfile：
