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#
# 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.

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