今天在完善我之前寫的LAMP做加速和優化時，所有完成在啓動httpd是提示如下：
[root@localhost modules]# /etc/init.d/httpd restart
Syntax error on line 232 of /usr/local/apache2/conf/httpd.conf:
Cannot load /usr/local/apache2/modules/libphp5.so into server: /usr/local/apache2/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied
通過查看selinux日誌：
type=AVC msg=audit(1294050945.203:51): avc: denied { execmod } for pid=22778 comm="httpd" path="/usr/local/apache2/modules/libphp5.so" dev=dm-5 ino=1212536 scontext=root:system_r:unconfined_t:s0-s0:c0.c1023 tcontext=system_u:object_r:lib_t:s0 tclass=file

得知要改 /usr/local/apache2/modules/libphp5.so 的context值，goole+baidu半天得知：
[root@localhost modules]# chcon -c -v -R -u system_u -r object_r -t textrel_shlib_t /usr/local/apache2/modules/libphp5.so
再次啓動，問題解決！
[root@localhost modules]# /etc/init.d/httpd restart
抓緊時間完成我的加速和優化
