FryShadow 90 Report post Posted February 24, 2010 server not found tu bila akses guna domain ke ? kebiasaannya mungkin sebab domain masih belum resolve ke semua DNS server user tersebut so, sebab tu jadi server not found tu. selain tu cuba analisis /var/log/messages kalau ada apa2 hint pasal apache or mysql Quote Share this post Link to post Share on other sites

Red-Hat-Enigma 0 Report post Posted February 27, 2010 Langkah 1. Cuba berikan info domain yang dah register tu. Sekurangnya boleh la kawan kawan kat sini cuba buatkan command nslookup/dig any <please_insert_domain_name_here> Langkah 2. Service Apache/httpd takkan automatically shutdown tanpa sebab. Check configuration httpd.conf ataupun jika anda menggunakan Apache2 , sila check configuration httpd-mpm.conf dimana StartServers value sekurangnya perlu adjust seperti dibawah : <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> Ni hanyalah contoh, cuba lain lain value mengikut kehendak anda. A wise sysadmin always checks his/her logs, jadi cuba periksa log /var/log/httpd/access_log atau /var/log/httpd/error_log (access.log/error.log which ever sebab lain platform OS, lain configuration). Selalu sangat diberikan "hints" kalau ada masalah apa apa didalam fail log tersebut. Kalau ada, sila post disini. Langkah 3.
