지금 제가 운영하는 홈페이지의 서버는 리눅스 입니다.
알짜 6.0 으로 설치되었구요....
서버환경은..
펜티엄 800, 512메가 램 으로 구성되어져 있습니다.
그리고, idc 에 입주해 있구요...
아파치, mysql, dns, sendmail 을 가동하고 있습니다.
그런데...
문제가요....
예전에는 하루 접속이 5000 건 이하라서 별 문제가 없었는데...
요즘 하루에 15000 이상의 사람이 접속을 하는 바람에 서버가 죽어나고 있습니다.

Swap: 265064 107140 157924
free 를 하면 이정도입니다.

http.conf 의 설정은....
#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 120
#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100
#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 15
#
# Server-pool size regulation. Rather than making you guess how many
# server processes you need, Apache dynamically adapts to the load it
# sees --- that is, it tries to maintain enough server processes to
# handle the current load, plus a few spare servers to handle transient
# load spikes (e.g., multiple simultaneous requests from a single
# Netscape browser).
#
# It does this by periodically checking how many servers are waiting
# for a request. If there are fewer than MinSpareServers, it creates
# a new spare. If there are more than MaxSpareServers, some of the
# spares die off. The default values are probably OK for most sites.
#
MinSpareServers 5
MaxSpareServers 20
#
# Number of servers to start initially --- should be a reasonable ballpark
# figure.
#
StartServers 5
#
# Limit on total number of servers running, i.e., limit on the number
# of clients who can simultaneously connect --- if this limit is ever
# reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW.
# It is intended mainly as a brake to keep a runaway server from taking
# the system with it as it spirals down...
#
MaxClients 300
#
# MaxRequestsPerChild: the number of requests each child process is
# allowed to process before the child dies. The child will exit so
# as to avoid problems after prolonged use when Apache (and maybe the
# libraries it uses) leak memory or other resources. On most systems, this
# isn't really needed, but a few (such as Solaris) do have notable leaks
# in the libraries. For these platforms, set to something like 10000
# or so; a setting of 0 means unlimited.
#
# NOTE: This value does not include keepalive requests after the initial
# request per connection. For example, if a child process handles
# an initial request and 10 subsequent "keptalive" requests, it
# would only count as 1 request towards this limit.
#
MaxRequestsPerChild 0
이렇게 설정되어져 있습니다.
제가 알고자 하는것은...
설정이 잘못되었는지...
아니면 설정을 바꾸어서 서버가 안정화 될 수 있는지...
아니면 램을 확충을 해야 하는지..
서버를 분리해야 하는지...
저에게 조언을 부탁드립니다..
