PHP下解決Cannot find module (IP-MIB)的問題

現(xiàn)象

最近工作中給公司的系統(tǒng)中增加了一些網(wǎng)絡(luò)有關(guān)的功能，它是基于GatewayWorker的，啟動(dòng)后報(bào)告類似如下的錯(cuò)誤信息：
Cannot find module (IP-MIB): At line 0 in (none)
Cannot find module (IF-MIB): At line 0 in (none)
Cannot find module (TCP-MIB): At line 0 in (none)

Cannot find module (SNMP-NOTIFICATION-MIB): At line 0 in (none)
Cannot find module (SNMPv2-TM): At line 0 in (none)

原因

根據(jù)錯(cuò)誤信息和網(wǎng)上找到的資料，說是沒有開啟php_snmp.dll這個(gè)擴(kuò)展，但是查看PHP.ini，發(fā)現(xiàn)該擴(kuò)展其實(shí)是打開的，進(jìn)一步深入分析，確認(rèn)應(yīng)該是本機(jī)沒有安裝net-SNMP。

解決

到net-SNMP下載一個(gè)安裝包，注意只有32位的，不過64位機(jī)器上也可以用。運(yùn)行該安裝包使用默認(rèn)路徑安裝完畢后，確認(rèn)PHP.ini中開啟了php_snmp.dll，重新啟動(dòng)GatewayWorker，問題解決。
