已安裝PHP GD-library但未在CentOS 6.4上運行

Question

我已經從remi repo安裝php 5.5.6，bun phpinfo()顯示沒有GD庫和gd_info()函數不存在。

擴展在/etc/php.d/gd.ini中啓用，但仍然沒有。

我也試着重新安裝php-gd庫，它重新安裝成功，但一切仍然像以前一樣。

Complete! 

之後我重新啓動服務器，但沒有改變。

擴展名仍在gd.ini文件中啓用。

文件gd.so存在於/usr/lib64/php/modules中。

但有一個很大的問題（我認爲這是真正的原因）：開始從主機的PHP腳本時，我得到警告：

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/gd.so' - libvpx.so.0: cannot map zero-fill pages: Cannot allocate memory in Unknown on line 0

比我試圖重新安裝libvpx，重新啓動服務器，然後再次 - 沒有變化：同樣的PHP的警告unable to load library ....

請幫助 - 這個問題讓我發瘋:(
