docker-docker中如何给PHP安装扩展

龙月飞虹

先进入到容器中
1.安装依赖
apt-get install -y zlib1g-dev libfreetype6-dev libjpeg62-turbo-dev libpng-dev
如果遇到zlib1g-dev报错：
root@d3228f96b7f0:/etc/apt# apt-get install -y zlib1g-dev libfreetype6-dev libjpeg62-turbo-dev libpng-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
zlib1g-dev : Depends: zlib1g (= 1:1.2.11.dfsg-1+deb10u2) but 1:1.2.11.dfsg-2+deb11u2 is to be installed
E: Unable to correct problems, you have held broken packages.请参照：docker中安装zlib

2.安装gd扩展
docker-php-ext-install gd

creating gd.la
(cd .libs && rm -f gd.la && ln -s ../gd.la gd.la)
/bin/bash /usr/src/php/ext/gd/libtool --mode=install cp ./gd.la /usr/src/php/ext/gd/modules
cp ./.libs/gd.so /usr/src/php/ext/gd/modules/gd.so
cp ./.libs/gd.lai /usr/src/php/ext/gd/modules/gd.la
PATH="$PATH:/sbin" ldconfig -n /usr/src/php/ext/gd/modules
----------------------------------------------------------------------
Libraries have been installed in:
   /usr/src/php/ext/gd/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'.
