CIX. SNMP 函数库

简介

需求

为了在 Unix 中使用 SNMP 函数库，您需要安装 UCD SNMP 或 NET-SNMP 包。在 Windows 中，这些函数只能用于 NT，而不能用于 Win95/98。

安装

重点：为了使用 UCD SNMP 包，您需要在编译之前将 NO_ZEROLENGTH_COMMUNITY 定义为 1。在 configuring UCD SNMP 之后，编辑 config.h，查找 NO_ZEROLENGTH_COMMUNITY，将 #define 所在行的注释去掉。修改后应该类似这样：
#define NO_ZEROLENGTH_COMMUNITY 1
然后使用 --with-snmp[=DIR] 选项编译 PHP。

如果您在联合 SNMP 命令时看到奇怪的分段错误，则不要继续上述的指令。如果您不想重新编译 UCD SNMP，可以使用 --enable-ucd-snmp-hack 开关编译 PHP，此开关将避开上述错误。

Windows 版本在目录 mibs 中包含了支持 SNMP 的文件。此目录应该移到 DRIVE:\usr\mibs，其中 DRIVE 是安装 PHP 所在的驱动器名，例如：c:\usr\mibs。

运行时配置

Just a quick note on PHP SNMP instalation on Windows machines (IIS 5.x /
Win2k SP2 etc...) 
I had installed PHP into C:\PHP.. (standard stuff
eh?)

Whilst I had followed the instructions for the installation of
SNMP (put php_snmp.dll in extension_dir, uncomment entry in php.ini and all
mib files located on the same drive where php was installed  (in this case
c:\usr\mibs right?) I still ran into trouble like "Cannot find module
(IP-MIB): At line 0 in (none)..." appearing on the bottom of every php
that page I was viewing which existed on a drive other than C:\
drive...

It seams that the mibs dir (and content thereof) have to be
located on every volume where a php file will be executed from.

For
example :-
If you have a php file as
"C:\INETPUB\WWWROOT\snmp1.php" then the coresponding
"C:\USR\MIBS\*.*" has to be present (as mentioned in the
install.txt).

Now here comes the catch...

If you have a
"D:\INETPUB\PHPROOT\snmp1.php" file, then a copy of the mib files
have to be in "D:\USR\MIBS\*.*" as well (the same mib files that
are on the C:\ drive and same basic location
<drive>:\USR\MIBS).

(Or in short : Copy the C:\USR dir (inc
mibs dir) to *every* drive you intend to have .php files accessed from. 
Done!)

Hope this helps other PHParians.

Keep up the *Great*
work!!!
