Question

为什么没有加载模块？

这是我的Dockerfile：

FROM php:5.6-apache

# Install PHP extensions and PECL modules.
RUN buildDeps=" \
        libbz2-dev \
        libmemcached-dev \
        libmysqlclient-dev \
        libsasl2-dev \
    " \
    runtimeDeps=" \
        curl \
        git \
        libfreetype6-dev \
        libicu-dev \
        libjpeg-dev \
        libldap2-dev \
        libmcrypt-dev \
        libmemcachedutil2 \
        libpng12-dev \
        libpq-dev \
        libxml2-dev \
    " \
    && apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y $buildDeps $runtimeDeps \
    && docker-php-ext-install bcmath bz2 calendar iconv intl mbstring mcrypt mysql mysqli opcache pdo_mysql pdo_pgsql pgsql soap zip \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install gd \
    && docker-php-ext-configure ldap --with-libdir=lib/x86_64-linux-gnu/ \
    && docker-php-ext-install ldap \
    && docker-php-ext-install exif \
    && pecl install memcached-2.2.0 redis \
    && docker-php-ext-enable memcached.so redis.so \
    && apt-get purge -y --auto-remove $buildDeps \
    && rm -r /var/lib/apt/lists/* \
    && a2enmod rewrite

RUN a2enmod rewrite
RUN usermod -u 1000 www-data
RUN usermod -G staff www-data

这是php -m：

的输出

例如，没有日历扩展，但它在Dockerfile本身中定义。此外，exif不会出现在列表中。这里有什么不对？

Answer 1

解决方案是，php.ini还没有相应更新。

...
extension=gd.so
extension=calendar.so
extension=exif.so
extension=xdebug.so
extension=soap.so
extension=opcache.so
...

现在它有效。

Answer 2

您可以在Dockerfile中添加命令以在构建后激活扩展。例如，要启用日历扩展名，请添加：

RUN php5enmod calendar

Docker不安装PHP模块
