VPS با دو تا سايت و حدود 100-200 نفر آنلاين گاهي هنگ ميكنه و حتي با putty هم به زحمت ميشه httpd رو ريستارت كرد. (با ريستارت كردن httpd مشكل حل ميشه) كسي تا حالا با اين مشكل برخورده؟ راه حلش چيه؟

وقتي اين مشكل پيش مياد در قسمت Service Monitor دايركت ادمين مقابل httpd و mysqld پر ميشه از pid

اینم مشکل شمارو داشته البته این خودش به بقیه vps میداده و میگه که یه دفعه روی همه vpsها apache مشکل پیدا میکرده.اخر هم مشکل رو در crond پیدا کرده.شما ببین توی cron چی داری.اینجور که این گفته ممکن هست اصلا مشکل از شما نباشه و از دیگر vpsهایی باشه که روی اون سرور هستن!

Timeout 300
KeepAlive On
MaxKeepAliveRequests 300
KeepAliveTimeout 15
MinSpareServers 5
MaxSpareServers 20
StartServers 8
MaxClients 150
MaxRequestsPerChild 0

منم فكر ميكنم مربوط به همين پارامتر ها باشه. چون تعداد بازديد كننده كه از يه حدي كمتره لود سايت پايينه اما وقتي از يه حدي مي گذره سرور هنگ ميكنه. ok ببينم چي ميشه.

با تنظيم اين پارامتر ها و نصب فايروال توسط پشتيباني مشكل هنگ كردن حل شده اما الان لود بالاست اكثر اوغات روي 5 و گاهي تا 20 هم ميره بالا. اين مشكل به خاطر چيه؟

اینکه بعضی اوقات خیلی load بالا میره هم طبیعی هست.اگر دائما بالا باشه بحثش متفاوت هست

اما سرعت سايت به شدت كم شده (با سايت هاي چك كننده سرعت هم تست كردم) يك نرم افزار نمايش دهنده مراجعين ميزان Direct Access رو براي 12 ساعت حدود 20000 تا زده بود كه غير طبيعيه. اين ممكنه به خاطر حملات DoS باشه؟

مرسي. ليستي از اي پي ها مياد كه يه عدد (حدس ميزنم تعداد Request يا كانكشن باشه) جلوشه. اين اعداد نشون دهنده چيه و چطوري ميشه يه اي پي رو بلاك كرد؟
