php - tp3.2 uses memcache extension and reports error 502

Question

1. Environment: mac nginx php-fpm

2. PHP’s memcache extension has been installed

3. Use memcache in the code

4. Access in the browser

5. nginx error log

Have any brothers encountered this kind of problem? I've been working on it for a long time and can't find the reason.
The memcache server is built on another Linux server. It can be accessed normally and other sites are in normal use.
Personal judgment It should be a problem with my personal configuration environment.

Answer 1

It’s probably a version issue, so I’ll try the next memcache extension. . .

Answer 2

The visual inspection is that the php-fpm service is abnormal, and the program has not reached the PHP stage at all

Answer 3

Try to access a page that does not operate memcache and see if the error is still reported
