判断apache的工作模式是prefork模式还是worker模式

作者:袖梨 2022-06-25

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

 代码如下 复制代码

#
# 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"

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


LockFile "logs/accept.lock"

#
# 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

# 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

# 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

# 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

# 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

# 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

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