Windows Server + Apache 注意事項
[1] - Disabling the QoS
We suggest disabling the "Quality of Service" (or QoS) network driver from Microsoft if you primarily use the machine as an Apache Server,
as Apache does not support the QoS extensions to the WinSock API.
[2]
Most Firewall programs, Web Spam filters and other TCP/IP driver-based products (including spyware!) do not correctly implement the entire WinSock API.
The shortcuts taken by the developers of such products cause Apache to fail.
[3]
Apache fall back to more basic (but slower) techniques. This resolves most, but not all of the potential problems.
EnableSendfile Off EnableMMAP Off Win32DisableAcceptEx
Win32DisableAcceptEx
Multi-Processing Module (MPM)
AcceptEx() is a Microsoft WinSock v2 API that provides some performance improvements over the use of the BSD style accept() API in certain circumstances.
Some popular Windows products, typically virus scanning or virtual private network packages,
have bugs that interfere with the proper operation of AcceptEx().
沒有遇到以下 Error 就不用 Disable AcceptEx() - 加 Win32DisableAcceptEx
[error] (730038)An operation was attempted on something that is not a socket.: winnt_accept: AcceptEx failed. Attempting to recover.
Module: mpm_winnt
mpm_winnt - This Multi-Processing Module is optimized for Windows NT.
It uses a single control process which launches a single child process which in turn creates threads to handle requests
ThreadsPerChild N
This directive sets the number of threads created by each child process.
The child creates these threads at startup and never creates more.
If using an MPM like mpm_winnt, where there is only one child process
This number should be high enough to handle the entire load of the server.
Default:
- mpm_winnt: 65
- others: 25
MaxRequestsPerChild N (作用: 防止大量 memory leakage)
After MaxRequestsPerChild requests, the child process will die.
If MaxRequestsPerChild is 0, then the process will never expire. <= 唔建議
* For KeepAlive requests, only the first request is counted towards this limit.
Default:
- mpm_winnt: 0
- other: 10000
Bug ...
... [crit] (OS 6)The handle is invalid. : master_main: create child process failed. Exiting.
ThreadLimit number
This directive sets the maximum configured value for ThreadsPerChild for the lifetime of the Apache httpd process.
Any attempts to change this directive during a restart will be ignored.
ThreadsPerChild can be modified during a restart up to the value of this directive
If ThreadLimit is set to a value much higher than ThreadsPerChild, extra unused shared memory will be allocated.
Default:
other: 64
mpm_winnt: 1920
ThreadStackSize size
sets the size of the stack (for autodata) of threads which handle client connections and call modules to help process those connections.
In most cases the operating system default for stack size is reasonable, but there are some conditions where it may need to be adjusted:
- On platforms with a relatively small default thread stack size
(Apache may crash when using some third-party modules which use a relatively large amount of autodata storage.)
- On platforms where the default thread stack size is significantly larger than necessary for the web server configuration
ReceiveBufferSize & SendBufferSize
The server will set the TCP receive/send buffer size to the number of bytes specified.
If set to the value of 0, the server will use the OS default.
* required to elicit better performance on high speed, high latency connections.
總結
使用以下 Settings 就可以了
<IfModule mpm_winnt_module>
ThreadsPerChild 64
MaxRequestsPerChild 2048
</IfModule>
Install / Uninstall Service
Once you have confirmed that Apache runs correctly as a console application you can install,
control and uninstall the pseudo-service with the same commands as on Windows NT.
# Install Apache as a service
httpd -k install
# 用其他名
httpd -k install -n "MyServiceName"
# 設定不同 service 不同 configure
httpd -k install -n "MyServiceName" -f "c:\files\my.conf"
(-f specifies an absolute or relative path to a particular configuration file)
# uninstall service
httpd -k uninstall
httpd -k uninstall -n "MyServiceName"
# Start / Stop Service
httpd -k stop | start | restart
P.S.
相當於 NET STOP / NET START 指令
# Verify the compiled value
httpd -V
# Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Apache Group\Apache\

EnableMMAP
Default: On
Use memory-mapping to read files during delivery
EnableSendfile
Default: Off
httpd may use the sendfile support from the kernel to transmit file contents to the client
On: Apache httpd uses sendfile to deliver the file contents without ever reading the file if the OS supports it.
This sendfile mechanism avoids separate read and send operations, and buffer allocations.
With a network-mounted DocumentRoot (e.g., NFS, SMB, CIFS, FUSE),
the kernel may be unable to serve the network file through its own cache.
