问题如下：
解决方法：
1、首先查看源码安装的php模块中是否有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 # 出现告警是因为此模块不存在，须要编译生成此模块并重新加载
-rwxr-xr-x 1 root root 1430846 Aug 21 19:38 opcache.so
[root@nms ldap]#
2、如何本机中已经有ldap.so，只须要在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 following 868 ; syntax: 869 extension=ldap.so #新添加内容 870 ; 871 ; extension=modulename.extension 872 ; 873 ; For example, on Windows: 874 ; 875 ; extension=msql.dll 876 ; 877 ; ... or under UNIX: 878 ; 879 ; extension=msql.so 880 ; 881 ; ... or with a path: 882 ; 883 ; extension=/path/to/extension/msql.so 884 ;
3、如果相应的模块不存在
3.1下载相应的php版本源码到主目录，进行源码编译ldap模块(重点，其他模块如果缺失编译方法一样）
[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/ #进入模块所在的源码位置
[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再次进入前端安装
发现PHP LDAP模块 OK!!
5、至此zabbix 前面安装 “Check of pre-requisites”全部OK
