使用 docker-php-ext-install 安装 PHP 扩展

Question

为了解决问题，我现在尝试通过安装 mysql pdo

docker-php-ext-install

正如 php 镜像的自述文件中所指出的。

但是我的通话失败，说明：

Libraries have been installed in:
   /usr/src/php/ext/mysqli/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Don't forget to run 'make test'.

ERROR: Service 'phlaconapp' failed to build: The command '/bin/sh -c docker-php-ext-install mysqli mysqlnd pdo pdo_mysql zip' returned a non-zero code: 1

这是我的 docker-compose.yml:

phlaconapp:
    hostname: phaclonapp
    dockerfile: Dockerfile
    build: ./
    ports:
        - "1080:80"
        - "1043:433"
    environment:
        TERM: xterm-color
        ENVIRONMENT: dev
    volumes:
        - ./:/var/www/html/

    volumes:

    ports: ["3306:3306"]
    environment:
        MYSQL_ROOT_PASSWORD: 'root'

这是我的 Dockerfile:

FROM php:5.6-apache

RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" && 
    php -r "if (hash_file('SHA384', 'composer-setup.php') === '070854512ef404f16bac87071a6db9fd9721da1684cd4589b1196c3faf71b9a2682e2311b36a5079825e155ac7ce150d') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" && 
    php composer-setup.php && 
    php -r "unlink('composer-setup.php');"


RUN apt-get update && 
    apt-get install vim git -y
RUN docker-php-ext-install mysqli mysqlnd pdo pdo_mysql zip 

RUN  cd /  && 
    git clone --depth=1 git://github.com/phalcon/cphalcon.git && 
    cd cphalcon/build && 
    ./install

RUN echo "extension=phalcon.so" > /usr/local/etc/php/conf.d/phalcon.ini
RUN a2enmod rewrite

并且运行 docker-compose build 将无法完成。

不久前我也遇到了同样的问题。我启动了一个容器，并向该容器中输入了 ext-install 命令。找到所有依赖项后，我将它们写入 Dockerfile。

示例：

RUN apt-get update && apt-get install -y \
libmcrypt-dev \
&& docker-php-ext-install -j$(nproc) mcrypt

在运行 docker-php-ext-install mcrypt 之前需要 libmcrypt-dev 依赖项

我检查了我的旧 Dockerfiles 并发现了一些可能对您有帮助的内容

FROM php:5.6-apache

RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libmcrypt-dev \
        libpng12-dev \
    libicu-dev \
     libxml2-dev \
    vim \
        wget \
        unzip \
        git \
    && docker-php-ext-install -j$(nproc) iconv intl xml soap mcrypt opcache pdo pdo_mysql mysqli mbstring \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
