自訂403權限不足訊息，以避免洩漏伺服器版本等訊息
修改
\etc\httpd\conf.dwelcome.conf
將 ErrorDocument 403 整行修改為
ErrorDocument 403 “<div align=center>403 Forbidden. You don’t have permission to access.</div>"

自訂404指不到網頁訊息\
修改
\etc\httpd\conf\httpd.conf
#ErrorDocument 404 /missing.html

#ErrorDocument 404 “/cgi-bin/missing_handler.pl"
改為
ErrorDocument 404 /err/
ps: /err/ 為自訂的網頁

改完後，重新啟動apache
service httpd restart
