8. In the middle, zlib.so is obviously compiled and configured, but it is not loaded
Solution: By viewing the php-fpm log as follows, it is found that it is a compilation problem. Make clean in the root directory of the php source code and recompile zlib, and you are done.
NOTICE: PHP message: PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) /usr/local/php-7.0.10/lib/php/extensions/no-debug-non-zts-20151012/zlib.so' in Unknown on line 0
