There are - additional tunable parameters included here, to be used - cautiously by an informed system administrator. - -TUNING - - To tune the web server, the number of simultaneous socket - connection requests are limited by: - - somaxconn Sets the maximum number of pending requests - allowed to wait on a listening socket. The - default value in Digital UNIX V3.2 is 8. - This patch kit increases the default to 1024, - which matches the value in Digital UNIX V4.0. - - sominconn Sets the minimum number of pending connections - allowed on a listening socket. When a user - process calls listen with a backlog less - than sominconn, the backlog will be set to - sominconn. sominconn overrides somaxconn. - The default value is 1. - - The effectiveness of tuning these parameters can be monitored by - the sobacklog variables available in the kernel: - - sobacklog_hiwat Tracks the maximum pending requests to any - socket. The initial value is 0. - - sobacklog_drops Tracks the number of drops exceeding the - socket set backlog limit. The initial - value is 0. - - somaxconn_drops Tracks the number of drops exceeding the - somaxconn limit. When sominconn is larger - than somaxconn, tracks the number of drops - exceeding sominconn. The initial value is 0. - - TCP timer parameters also affect performance. Tuning the following - require some knowledge of the characteristics of the network. - - tcp_msl Sets the tcp maximum segment lifetime. - This is the maximum lifetime in half - seconds that a packet can be in transit - on the network. This value, when doubled, - is the length of time a connection remains - in the TIME_WAIT state after a incoming - close request is processed. The unit is - specified in 1/2 seconds, the initial - value is 60. - - tcp_rexmit_interval_min - Sets the minimum TCP retransmit interval. - For some WAN networks the default value may - be too short, causing unnecessary duplicate - packets to be sent. The unit is specified - in 1/2 seconds, the initial value is 1. - - tcp_keepinit This is the amount of time a partially - established connection will sit on the listen - queue before timing out (<EM>e.g.</EM>, if a client - sends a SYN but never answers our SYN/ACK). - Partially established connections tie up slots - on the listen queue. If the queue starts to - fill with connections in SYN_RCVD state, - tcp_keepinit can be decreased to make those - partial connects time out sooner. This should - be used with caution, since there might be - legitimate clients that are taking a while - to respond to SYN/ACK. The unit is specified - in 1/2 seconds, the default value is 150 - (ie. 75 seconds). - - The hashlist size for the TCP inpcb lookup table is regulated by: - - tcbhashsize The number of hash buckets used for the - TCP connection table used in the kernel. - The initial value is 32. For best results, - should be specified as a power of 2. For - busy Web servers, set this to 2048 or more. - - The hashlist size for the interface alias table is regulated by: - - inifaddr_hsize The number of hash buckets used for the - interface alias table used in the kernel. - The initial value is 32. For best results, - should be specified as a power of 2. - - ipport_userreserved The maximum number of concurrent non-reserved, - dynamically allocated ports. Default range - is 1025-5000. The maximum value is 65535. - This limits the numer of times you can - simultaneously telnet or ftp out to connect - to other systems. - - tcpnodelack Don't delay acknowledging TCP data; this - can sometimes improve performance of locally - run CAD packages.

If Apache is compiled normally, it - will install a number of optional modules in the - <CODE>\Apache\modules</CODE> directory. To activate these, or other - modules, the new <A HREF="mod/mod_so.html#loadmodule">LoadModule</A> - directive must be used. For example, to active the status module, - use the following (in addition to the status-activating directives - in <CODE>access.conf</CODE>):</P> -<PRE> - LoadModule status_module modules/ApacheModuleStatus.dll -</PRE> - <P>Information on <A HREF="mod/mod_so.html#creating">creating loadable - modules</A> is also available.</P> - <LI><P>Apache can also load ISAPI Extensions (<EM>i.e.</EM>, Internet Server - Applications), such as those used by Microsoft's IIS, and other - Windows servers. <A HREF="mod/mod_isapi.html">More information - is available.</A> -</UL> - -<H2><A NAME="service">Running Apache for Windows as a Service</A></H2> - -You can install Apache as a Windows NT service as follows: - -<PRE> - apache -i -n "service name" -</PRE> - -To install a service to use a particular configuration, specify the -configuration file when the service is installed: - -<PRE> - apache -i -n "service name" -f "\my server\conf\my.conf" -</PRE> - -To remove an Apache service, use - -<PRE> - apache -u -n "service name" -</PRE> - -The default "service name", if one is not specified, is "Apache". - -<P> - -Once a service is installed, you can use the <SAMP>-n</SAMP> option, in conjunction -with other options, to refer to a service's configuration file.

But in some cases it is easier to -work from the command line. - -<P> -When working with Apache it is important to know how it will find the -configuration files. You can specify a configuration file on the command line -in two ways: - -<UL> -<LI>-f specifies a path to a particular configuration file -</UL> -<PRE> apache -f "c:\my server\conf\my.conf"</PRE> -<PRE> apache -f test\test.conf</PRE> -<UL> -<LI>-n specifies the configuration file of an installed Apache service -</UL> -<PRE> apache -n "service name"</PRE> - -In these cases, the proper ServerRoot should be set in the configuration file. - -<P> - -If you don't specify a configuration file name with -f or -n, Apache will -use the file name compiled into the server, usually "conf/httpd.conf". Invoking -Apache with the -V switch will display this value labeled as SERVER_CONFIG_FILE. -Apache will then determine it's ServerRoot by trying the following, in this order: - -<UL> -<LI>A ServerRoot directive via a -C switch. -<LI>The -d switch on the command line. -<LI>Current working directory -<LI>A registry entry, created if you did a binary install. -<LI>The server root compiled into the server. -</UL> - -<P> -The server root compiled into the server is usually "/apache". -invoking apache with the -V switch will display this value -labeled as HTTPD_ROOT. - -<P> -When invoked from the start menu, Apache is usually passed no arguments, -so using the registry entry is the preferred technique for console Apache. - -<P> -During a binary installation, a registry key will have -been installed, for example: -<PRE> - HKEY_LOCAL_MACHINE\Software\Apache Group\Apache\1.3.4\ServerRoot -</PRE> - -<P> -This key is compiled into the server and can enable you to test -new versions without affecting the current version. Of course -you must take care not to install the new version on top of the -old version in the file system. - -<P> -If you did not do a binary install then Apache will in some -scenarios complain that about the missing registry key. This -warning can be ignored if it otherwise was able to find it's -configuration files. - -<P> -The value of this key is the "ServerRoot" directory, containing the -<SAMP>conf</SAMP> directory. When Apache starts it will read the -<SAMP>httpd.conf</SAMP> file from this directory. If this file -contains a <SAMP>ServerRoot</SAMP> directive which is different from -the directory obtained from the registry key above, Apache will forget -the registry key and use the directory from the configuration file. -If you copy the Apache directory or configuration files to a new -location it is vital that you update the <SAMP>ServerRoot</SAMP> -directory in the <SAMP>httpd.conf</SAMP> file to the new location. - -<P> -To run Apache from the command line as a console application, use the -following command: - -<PRE> - apache -</PRE> - -Apache will execute, and will remain running until it is stopped by pressing -control-C. - -<H2><A NAME="signalsrv">Signalling Service Apache when running</A></H2> - -On Windows NT, multiple instances of Apache can be run as services. -Signal an Apache service to start, restart, or shutdown as follows: - -<PRE> - apache -n "service name" -k start - apache -n "service name" -k restart - apache -n "service name" -k shutdown -</PRE> - -In addition, you can use the native NT NET command to -start and stop Apache services as follows: - -<PRE> - NET START "service name" - NET STOP "service name" -</PRE> - -<H2><A NAME="signal">Signalling Console Apache when running</A></H2> - -On Windows 95, Apache runs as a console application.
