  at part of "require modules " add require "modules/htmltext.pl"

c)chmod 777 /var/log/openwebmail.log

2)Couldn't create File /var/log/openwebmail.log! (Permission denied)
Suggetion:
touch /var/log/openwebmail.log
chcon -u system_u /var/log/openwebmail.log
chcon -t httpd_sys_script_rw_t /var/log/openwebmail.log
chcon -t httpd_unconfined_script_exec_t /var/www/cgi-bin/openwebmail/openwebmail*

說明一下這個部分
touch /var/log/openwebmail.log <==這是產生一個log檔
chcon -u system_u /var/log/openwebmail.log <==這是修改檔案使用者權限
chcon -t httpd_sys_script_rw_t /var/log/openwebmail.log <==這是修改寫入權限
chcon -t httpd_unconfined_script_exec_t /var/www/cgi-bin/openwebmail/openwebmail* <==這是修改檔案由什麼套件專用這些都是因為SELinux造成的，原本檔案、目錄權限只有使用檔案前面那串（rwxrwxrwx），在使用SELinux後，會多出一種管理 context type，context type會限制該目錄、檔案的使用原則，所以，在使用有安裝SELinux時，常常會出現apach、ftp明明 都設定好了，卻還是不能使用，多半出問題，都是SELinux在做怪


The End!
