httpd.conf file Configuration

Apache basic settings mainly to httpd.conf to set management, we want to modify the relevant settings Apache, mainly through the modification of httpd.cong to achieve. Let's take a look at Httpd.conf's content, which is divided into 3 major parts:
Section 1:global Environnement
Section 2: ' Main ' server revisit
Section 3:virtual Hosts

"The first part"

· ServerType Standalone
This means that Apache starts with standalone, or it can be inetd. The so-called standalone is to start to pick up all the wiring, and inetd is connected to the HTTP request to start, with the end of the connection, the burden is not very much? So it's usually started with standalone.
· ServerRoot "/USR/LOCAL/HTTPD"
This is Apache directory
• #LocdFile/use/local/httpd/logs/httpd.lock
Keep preset, do not change
· Pidfile/usr/local/httpd/logs/httpd.pid
This file records Apache's parent handler ID
· Scoreboardfile/usr/local/httpd/logs/httpd.scoreboard
Information for this file store handler
• #ResourceConfig conf/srm.conf
# AccessConfig conf/access.conf
Because we co-ordinate the management by httpd.conf, the two file presets are annotated, and you can keep the preset values unchanged
· Timeout
Set the time of the Stare timeout. If the client is not connected to the server for more than 300 seconds, or if the server has not yet transmitted information to the client for more than 300 seconds, the line is disconnected.
· KeepAlive on
allow the client to have multiple requests on the line, set to off to indicate not allowed
· Maxkeepaliverequests
Each time the largest request of the tree, the larger the number, the better the efficiency. 0 means no limit to
· Minspareserver 5
· Maxspareservers
Minspareserver 5 means that there will be at least 5 idle handlers, and if the actual number is less than this, the handler will be incremented. Maxspareservers 10 represents the largest number of idle processing programs, if your site is in great demand, you can set this number larger, don't arbitrarily set this number too large.
· Startservers 5
Number of servers at startup
MaxClients
Limit the maximum number of connections to the same time, of course, cannot be set too small, once this number is reached, you can no longer add users-Side
· Maxrequestperchild 0
Limit the number of requests before the result of a child handler, 0 means no Limit
• #Listen 3000
• #Listen 12.34.56.78:80
Use a different connection port or IP
· Bindaddress *
can answer * (all IP address), specified IP address or full domain name
• #LoadModule foo_module libexec/mod_foo.so
Use DSO module
# Extendedstatus on
to review Apache status information, preset to OFF (annotated)
"Part Two"

If the previous servertype is inetd, skip to serveradmin.
· Port
Standalone the connection ports that the server listens to, and of course it can be other port numbers less than 1023
· User Nobody
· Group Nobody
performing httpd users and Groups
· ServerAdmin Administrator's e-mail address
This is the administrator's e-mail address, if the Apache has a problem, will send a letter to the administrator, of course, you can also create a dedicated web account to receive the letter
· ServerName Your host name
This is the host name, if there is no domain name, can also use IP
· 　　DocumentRoot "Usr/local/httpd/htdocs"

•
Order Allow,deny

This is used to prevent others from seeing the contents of a file that begins with HT, not only the content of the protected. htaccess, but also the inner of the. htpasswd.Tolerance。 Of course, it can be written directly. If you have changes to accessfilename, for example, htaccess to. Accessht, please remember to make the relevant changes here, so as to prevent others from seeing Oh
• #CacheNegotiatedDocs

· Hostlookups off
If on, each time the IP is resolved to the name server, recording the name of the line (for example, www.apache.org) from min 牟簧偈 ben Qinglie ... Off to record only IP
