PHP cant find SNMP modules under Windows 7

问题:

I've enabled the SNMP module was trying to the functions in the module. I have set the MIBDIRS environment variable to where I have my mibs but I'm still getting these "Cannot find module" warnings:

Cannot find module (IP-MIB): At line 0 in (none)

My php.ini settings are:

mibdir=C:\\Users\username\Downloads\Applications\Dev\PHP\5.4\net-snmp-mibs\net-snmp-5.7.2.1\mibs
mibs=all
extension=php_snmp.dll

I'm on Windows.

And it still gives those errors...

Any insights please?

回答1:

The PHP docs is misleading for Windows; In order to get rid of the errors and have SNMP module working properly, you MUST add an environment variable in the System, called MIBDIRS and pointing to the location of your mib files.

On Windows 7 for example, that would be System Properties > Environment Variables > User variables section, click New and add MIBDIRS, with value of C:\usr\mibs (or wherever you put the mibs folder).

The files should be extracted using a Net-SNMP package, tested with version net-snmp-5.7.2.1 on PHP 5.4.7 using CLI mode.

Acording to PHP SNMP Instllation page:

The Windows distribution of Net-SNMP contains support files for SNMP in the mibs directory. This directory should be moved to DRIVE:\usr\mibs, where DRIVE must be replaced with the driveletter where PHP is installed on, e.g.c:\usr\mibs. Alternatively you may set MIBDIRS environment variable pointed to your MIBs folder.

Copied from another post:

Apparently there are 2 environment variables you can set. One is MIBDIRS which is where all the MIB files are. Another is MIBS, which I believe is which SNMP modules you want to load. By setting MIBS to ALL, I was able to get rid of the errors

回答4:

The php package doesn't include mibs folder, what you have to do is download the source file of net-snmp and copy the folder into your php directory

download link https://sourceforge.net/projects/net-snmp/files/net-snmp/5.7.3/

after that, unzip the zip file and copy the mibs folder to your php directory

for exmaple,copy it to C:\PHP\Extras\mibs Thne add a new system variable called MIBDIRS. Its value should be: C:\PHP\Extras\mibs

Finally, you can run php -m

and you issue will be resoved

I attach a screenshot for your reference.
