[root@LAMPconf]# /usr/local/apache/bin/apachectl configtest
Syntax error on line 223 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache/libexec/libphp4.so into server: /usr/local/apache/libexec/libphp4.so: cannot restore segment prot after reloc: Permission denied
原來是SELinux搞的，經常遇到類似的情況，一直忽略了他，越安全的越受到限制啊，解決辦法
1. chcon -t texrel_shlib_t /usr/local/apache/libexec/*.so
2.禁止SELinux：更改/etc/sysconfig/selinux 文件的內容爲 SELINUX=permissive或者disabled
部署公司產品就遇到這類問題。今天又遇見了，感覺有點熟悉。
