带Docker的PHP7.0-FPM：无法加载动态库OCI8

Question

我用PHP7.0-FPM和Apache 2.4创建了一个Docker镜像。我安装了InstantClient 12.2（基本+ sdk），我安装了oci8，如下所示：

RUN echo "instantclient,/usr/lib/oracle/12.2/instantclient"| pecl install oci8 && \
    echo "extension=oci8.so" > /etc/php/7.0/mods-available/oci8.ini && \
    ln -s /etc/php/7.0/mods-available/oci8.ini /etc/php/7.0/fpm/conf.d/20-oci8.ini

我不知道为什么，但是当我（重新）启动php7.0-fpm时，我收到了这个警告：

# service php7.0-fpm restart
 * Restarting PHP 7.0 FastCGI Process Manager php-fpm7.0
Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/oci8.so' - libmql1.so: cannot open shared object file: No such file or directory in Unknown on line 0

oci8.so和libmql1.so的位置似乎没问题：

我已将这4行添加到/etc/php/7.0/fpm/pool.d/www.conf：

env[LD_LIBRARY_PATH] = /usr/lib/oracle/12.2/instantclient
env[TNS_ADMIN] = /etc/oracle
env[ORACLE_BASE] = /usr/lib/oracle/12.2/instantclient
env[ORACLE_HOME] = /usr/lib/oracle/12.2/instantclient

我会错过什么吗？

谢谢

Answer 1

没关系 ！我在.conf错过了一个/etc/ld.so.conf.d/oracle-instantclient.conf

RUN echo "instantclient,/usr/lib/oracle/12.2/instantclient"| pecl install oci8 && \
echo "extension=oci8.so" > /etc/php/7.0/mods-available/oci8.ini && \
ln -s /etc/php/7.0/mods-available/oci8.ini /etc/php/7.0/fpm/conf.d/20-oci8.ini && \
echo /usr/lib/oracle/12.2/instantclient > /etc/ld.so.conf.d/oracle-instantclient.conf && \
ldconfig

尝试在/ etc / apache2 / envvars中添加那些env变量添加到文件的末尾，比如

• export LD_LIBRARY_PATH = / usr / lib / oracle / 12.2 / instantclient
• export TNS_ADMIN = / etc / oracle
• export ORACLE_BASE = / usr / lib / oracle / 12.2 / instantclient
• export ORACLE_HOME = / usr / lib / oracle / 12.2 / instantclient

这样apache用户就会在运行时使用这些变量。并检查用户/组的权限，它必须是www-data：www-data
