Alpinelinux下编译PHP OCI8扩展

Question

我正在尝试编译PHP OCI8 extension 并在Alpinelinux 下运行它。但似乎扩展对glibc 中定义的符号有一些依赖关系，但在musl libc 中缺少。

我可以使用任何现有的已编译 PHP OCI8 扩展吗？或者是否有任何解决方法可以使 oci8 扩展和 oracle 即时客户端与 alpinelinux 一起使用。

提前致谢！

FROM php:alpine3.13

我的 Alpine 解决方案很简单：使用 Instant Client v11 (11.2.0.4) 而不是 v12 (12.2.0.1)：

ENV LD_LIBRARY_PATH /usr/local/instantclient
ENV ORACLE_HOME /usr/local/instantclient

# Install Oracle Client and build OCI8 (Oracle Command Interface 8 - PHP extension)

RUN apk add php7-pear php7-dev gcc musl-dev libnsl libaio &&\
## Download and unarchive Instant Client v11
  curl -o /tmp/basic.zip https://raw.githubusercontent.com/bumpx/oracle-instantclient/master/instantclient-basic-linux.x64-11.2.0.4.0.zip && \
  curl -o /tmp/sdk.zip https://raw.githubusercontent.com/bumpx/oracle-instantclient/master/instantclient-sdk-linux.x64-11.2.0.4.0.zip && \
  curl -o /tmp/sqlplus.zip https://raw.githubusercontent.com/bumpx/oracle-instantclient/master/instantclient-sqlplus-linux.x64-11.2.0.4.0.zip && \
  unzip -d /usr/local/ /tmp/basic.zip && \
  unzip -d /usr/local/ /tmp/sdk.zip && \
  unzip -d /usr/local/ /tmp/sqlplus.zip && \
## Links are required for older SDKs
  ln -s /usr/local/instantclient_11_2 ${ORACLE_HOME} && \
  ln -s ${ORACLE_HOME}/libclntsh.so.* ${ORACLE_HOME}/libclntsh.so && \
  ln -s ${ORACLE_HOME}/libocci.so.* ${ORACLE_HOME}/libocci.so && \
  ln -s ${ORACLE_HOME}/lib* /usr/lib && \
  ln -s ${ORACLE_HOME}/sqlplus /usr/bin/sqlplus &&\
  ln -s /usr/lib/libnsl.so.2.0.0  /usr/lib/libnsl.so.1 &&\
## Build OCI8 with PECL
  echo "instantclient,${ORACLE_HOME}" | pecl install oci8 &&\
  echo 'extension=oci8.so' > /etc/php7/conf.d/30-oci8.ini &&\
#  Clean up
  apk del php7-pear php7-dev gcc musl-dev &&\
  rm -rf /tmp/*.zip /var/cache/apk/* /tmp/pear/

试试这些命令。

它在 Alpine 上的 Docker 下工作。

但是，您必须安装 GLIB Alpine 兼容层：https://github.com/sgerrand/alpine-pkg-glibc

# Install OCI8
COPY ./oracle-sdk /tmp/oracle-sdk
RUN apk add --no-cache libaio-dev && \
unzip /tmp/oracle-sdk/instantclient-basic-linux.x64-12.2.0.1.0.zip -d /usr/local/ && \
unzip /tmp/oracle-sdk/instantclient-sdk-linux.x64-12.2.0.1.0.zip -d /usr/local/ && \
unzip /tmp/oracle-sdk/instantclient-sqlplus-linux.x64-12.2.0.1.0.zip -d /usr/local/ && \
ln -s /usr/local/instantclient_12_2 /usr/local/instantclient && \
ln -s /usr/local/instantclient/libclntsh.so.* /usr/local/instantclient/libclntsh.so && \
ln -s /usr/local/libclntshcore.so.* /usr/local/instantclient/libclntshcore.so && \
ln -s /usr/local/instantclient/libocci.so.* /usr/local/instantclient/libocci.so && \
ln -s /usr/local/instantclient/sqlplus /usr/bin/sqlplus && \
docker-php-ext-configure oci8 --with-oci8=instantclient,/usr/local/instantclient && \
docker-php-ext-install oci8 && \
rm -rf /tmp/oracle-sdk

尝试过 Alpine 的人还没有找到方法。该问题并非特定于 PHP，因此请检查也使用 Oracle Instant Client 并尝试过 Alpine 的其他语言。例如，查看 Alpine 问题https://github.com/sgerrand/alpine-pkg-glibc/issues/31
