[heyanlong]

Need to confirm the running mode of php-fpm

[ximply]

static mode.

[ximply]

Use fastcgi.

[heyanlong]

daemonize no or yes?

[ximply]

default value, daemonize yes.

[heyanlong]

Maybe you can modify it to no.

[ximply]

But v3.3.2 is ok, why?

[heyanlong]

The technical implementation is somewhat different. v3.3.2 used unix socket.

[ximply]

Still nothing.

[ximply]

I just change daemonize to no, then run with: php-fpm >/dev/null 2>&1 &

[heyanlong]

php-fpm --daemonize no > /dev/null 2>&1 &

[ximply]

It works now!
