問題如下：

解決方法：

1、首先查看源碼安裝的php模塊中是否有ldap.so

[root@nms ldap]# ll? /usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/
total 1576
-rwxr-xr-x 1 root root? 129484 Aug 22 10:18 ldap.so # 出現告警是因為此模塊不存在，須要編譯生成此模塊并重新加載
-rwxr-xr-x 1 root root 1430846 Aug 21 19:38 opcache.so
[root@nms ldap]#

?

2、如何本機中已經有ldap.so，只須要在php.ini文件中添加extension=ldap.so

864 ; Dynamic Extensions ;865 ;;;;;;;;;;;;;;;;;;;;;;866 867 ; If you wish to have an extension loaded automatically, use the following868 ; syntax:869 extension=ldap.so #新添加內容870 ; 871 ; extension=modulename.extension872 ; 873 ; For example, on Windows:874 ; 875 ; extension=msql.dll876 ; 877 ; ... or under UNIX:878 ; 879 ; extension=msql.so880 ; 881 ; ... or with a path:882 ; 883 ; extension=/path/to/extension/msql.so884 ;

?

3、如果相應的模塊不存在

　　3.1下載相應的php版本源碼到主目錄，進行源碼編譯ldap模塊(重點，其他模塊如果缺失編譯方法一樣）

[root@nms ~]# tar jxvf php-7.1.7.tar.bz2 [root@nms ~]# ls anaconda-ks.cfg install.log lnmp-install.log php-7.1.7.tar.bz2 databases_backup_20170821115223 install.log.syslog php-7.1.7
[root@nms ldap]# cd /root/php-7.1.7/ext/ldap/ #進入模塊所在的源碼位置
[root@nms ldap]# ll

Libraries have been installed in:
?? /root/php-7.1.7/ext/ldap/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
?? - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
???? during execution
?? - add LIBDIR to the `LD_RUN_PATH' environment variable
???? during linking
?? - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
?? - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.

　4、http://192.168.0.198/zabbix/setup.php再次進入前端安裝

　　發現PHP LDAP模塊 OK!!

?5、至此zabbix 前面安裝 “Check of pre-requisites”全部OK
