我试过你的dockerfile脚本,发现了一些错误。Docker构建输出确实显示了对PDO模块进行解包和编译的痕迹:
但在PDO配置过程中失败,并出现错误:
checking for gawk... no
checking for nawk... nawk
checking if nawk is broken... no
checking for Informix driver for PDO... yes, shared
configure: error: INFORMIXDIR environment variable is not set. Please use --with
-pdo-informix=<DIR> or set the INFORMIXDIR environment variable.

我更改了构建模块的脚本,以便在运行configure之前设置informisdir。

又一次在别的地方失败了。查看模块构建文件时,它期望模块位于以下目录中:
-- config.m4 --
AC_MSG_CHECKING([for PDO includes])
if test -f $abs_srcdir/include/php/ext/pdo/php_pdo_driver.h; then
pdo_inc_path=$abs_srcdir/ext
elif test -f $abs_srcdir/ext/pdo/php_pdo_driver.h; then
pdo_inc_path=$abs_srcdir/ext
elif test -f $prefix/include/php/ext/pdo/php_pdo_driver.h; then
pdo_inc_path=$prefix/include/php/ext
else
AC_MSG_ERROR([Cannot find php_pdo_driver.h.])
fi
但在IBM Docker映像中,该文件位于:
root@faf18c3c0ef5:/usr/include# find ./ -name php_pdo_driver.h
./php/20170718/ext/pdo/php_pdo_driver.h
root@faf18c3c0ef5:/usr/include#
所以我在dockerfile中添加了一个“ln-s”来创建软链接。
以下是我修改的两个文件:
---install-informixpdo.sh ---
...
PDO_DIRECTORY=PDO_INFORMIX-1.3.3
PDO_FILENAME=$PDO_DIRECTORY.tgz
export INFORMIXDIR=/opt/ibm/informix
TMPDIR=/tmp
tar -xvf $TMPDIR/$PDO_FILENAME -C $TMPDIR/
cd $TMPDIR/$PDO_DIRECTORY
phpize && ./configure && make && make install
rm -r $TMPDIR/*
...
----------
和
--- dockerfile ---
....
ENV INFORMIXDIR /opt/ibm/informix
ENV PATH $INFORMIXDIR/bin:$PATH
COPY scripts/PDO_INFORMIX-1.3.3.tgz /tmp
COPY scripts/install-informixpdo.sh /tmp
RUN sudo ln -s /usr/include/php/20170718/ext /usr/include/php/ext
RUN sudo sh /tmp/install-informixpdo.sh
#Informix environment variables for Apache
COPY scripts/envvars.sh /tmp
...
-------------
通过这些更改,我可以在执行“docker build”命令时编译并安装模块。

Libraries have been installed in:
/tmp/PDO_INFORMIX-1.3.3/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.
----------------------------------------------------------------------
Build complete.
Don't forget to run 'make test'.

与apache配置一起使用的php加载模块:
root@99d4150d07ed:/# php -c /etc/php/7.2/apache2/conf.d/pdo.ini -m | grep inform
ix
pdo_informix
root@99d4150d07ed:/#
一个简单的连接,似乎也可以毫无问题地工作:
root@99d4150d07ed:/# cat t.php
<?php
$db = new PDO("informix:host=99d4150d07ed; service=9088;database=sysmaster; serv
er=informix; protocol=onsoctcp; EnableScrollableCursors=1;", "informix", "in4mix
");
print "Connection Established!</br></br>";
$stmt = $db->query("select * from systables");
$res = $stmt->fetch( PDO::FETCH_BOTH );
$rows = $res[0];
echo "Table contents: $rows.</br>";
?>
root@99d4150d07ed:/# php -c /etc/php/7.2/apache2/conf.d/pdo.ini t.php
Connection Established!</br></br>Table contents: systables.</br>root@99d4150d07e
d:/#
您可以在“install informixpdo.sh”文件中添加软链接创建和导出informixpdir。
