判断apache的工作模式是prefork模式还是worker模式_linux教程_开发教程

apache常用的工作模式有prefork和worker模式。运行命令httpd -l 或者apache2 -l ，输出的结果中如果含有prefork.c，那就是prefork模式，如果结果中含有worker.c，那就是worker模式。

知道模式之后我们可以在apache的confextrahttpd-mpm.conf 进行编辑了

# Server-Pool Management (MPM specific)

# PidFile: The file in which the server should record its process

# identification number when it starts.

# Note that this is the default PidFile for most MPMs.

PidFile "logs/httpd.pid"

</IfModule>

# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.

LockFile "logs/accept.lock"

</IfModule>

# Only one of the below sections will be relevant on your

# installed httpd. Use "apachectl -l" to find out the

# active mpm.

# prefork MPM

# StartServers: number of server processes to start

# MinSpareServers: minimum number of server processes which are kept spare

# MaxSpareServers: maximum number of server processes which are kept spare

# MaxClients: maximum number of server processes allowed to start

# MaxRequestsPerChild: maximum number of requests a server process serves

StartServers 5

MinSpareServers 5

MaxSpareServers 10

MaxClients 150

MaxRequestsPerChild 0

</IfModule>

# worker MPM

# StartServers: initial number of server processes to start

# MaxClients: maximum number of simultaneous client connections

# MinSpareThreads: minimum number of worker threads which are kept spare

# MaxSpareThreads: maximum number of worker threads which are kept spare

# ThreadsPerChild: constant number of worker threads in each server process

# MaxRequestsPerChild: maximum number of requests a server process serves

StartServers 2

MaxClients 150

MinSpareThreads 25

MaxSpareThreads 75

ThreadsPerChild 25

MaxRequestsPerChild 0

</IfModule>

# BeOS MPM

# StartThreads: how many threads do we initially spawn?

# MaxClients: max number of threads we can have (1 thread == 1 client)

# MaxRequestsPerThread: maximum number of requests each thread will process

StartThreads 10

MaxClients 50

MaxRequestsPerThread 10000

</IfModule>

# NetWare MPM

# ThreadStackSize: Stack size allocated for each worker thread

# StartThreads: Number of worker threads launched at server startup

# MinSpareThreads: Minimum number of idle threads, to handle request spikes

# MaxSpareThreads: Maximum number of idle threads

# MaxThreads: Maximum number of worker threads alive at the same time

# MaxRequestsPerChild: Maximum number of requests a thread serves. It is

# recommended that the default value of 0 be set for this

# directive on NetWare. This will allow the thread to

# continue to service requests indefinitely.

ThreadStackSize 65536

StartThreads 250

MinSpareThreads 25

MaxSpareThreads 250

MaxThreads 1000

MaxRequestsPerChild 0

MaxMemFree 100

</IfModule>

# OS/2 MPM

# StartServers: Number of server processes to maintain

# MinSpareThreads: Minimum number of idle threads per process,

# to handle request spikes

# MaxSpareThreads: Maximum number of idle threads per process

# MaxRequestsPerChild: Maximum number of connections per server process

StartServers 2

MinSpareThreads 5

MaxSpareThreads 10

MaxRequestsPerChild 0

</IfModule>

# WinNT MPM

# ThreadsPerChild: constant number of worker threads in the server process

# MaxRequestsPerChild: maximum number of requests a server process serves

ThreadsPerChild 150

MaxRequestsPerChild 0

</IfModule>

我们如果是windows系统一般是使用最后面的winnt mpm来操作了。
