Linux服务器---apache配置文件

Apache配置文件

Apache的配置文件默认路径是“/etc/httpd/conf/httpd.conf”，编辑该文件就可以修改Apache的配置

1、设置网页主目录，参数DocumentRoot就是网页存放的主目录。打开配置文件httpd.conf，查找DocumentRoot（大约292行）

[root@localhost ~]# gedit /etc/httpd/conf/httpd.conf

# DocumentRoot: The directory out of which you will serve your

# documents. By default, all requests are taken from this directory, but

# symbolic links and aliases may be used to point to other locations.

DocumentRoot "/var/www/html"   //当前默认是在"/var/www/html"目录下，所有的网页必须放在这里

2、设置连接端口，通过参数listen来设置连接的端口，默认80.（大约136行）

[root@localhost ~]# gedit /etc/httpd/conf/httpd.conf

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, in addition to the default. See also the <VirtualHost>

# directive.

#

# Change this to Listen on specific IP addresses as shown below to 

# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)

#

#Listen 12.34.56.78:80

Listen 80

3、设置连接超时，参数timeout，当连接超过一定的空闲时间，就会自动断开。（大约68行）

# Timeout: The number of seconds before receives and sends time out.

#

Timeout 60

4、设置字符集，参数AddDefaultCharset，建议最好设置utf-8，这是通用的。（大约753行）

# Specify a default charset for all content served; this enables

# interpretation of all content as UTF-8 by default.  To use the 

# default browser choice (ISO-8859-1), or to allow the META tags

# in HTML content to override this choice, comment out this

# directive:

#

AddDefaultCharset UTF-8

5、设置服务器名称，参数ServerName。这是服务器的域名，必须有dns解析才可以访问。如果你没有合法的域名，那么只能通过ip地址来访问

# ServerName gives the name and port that the server uses to identify itself.

# This can often be determined automatically, but we recommend you specify

# it explicitly to prevent problems during startup.

#

# If this is not set to valid DNS name for your host, server-generated

# redirections will not work.  See also the UseCanonicalName directive.

#

# If your host doesn't have a registered DNS name, enter its IP address here.

# You will have to access it by its address anyway, and this will make 

# redirections work in a sensible way.

#

#ServerName www.example.com:80

6、设置keepalive，提高网络效率，默认是关闭的。（大约76行）

# KeepAlive: Whether or not to allow persistent connections (more than

# one request per connection). Set to "Off" to deactivate.

#

KeepAlive Off

7、设置keepaliverequest，设置为0 的时候没有限制，不过最好还是用默认值，或者自己根据情况来改变。（大约83行）

# MaxKeepAliveRequests: The maximum number of requests to allow

# during a persistent connection. Set to 0 to allow an unlimited amount.

# We recommend ou leave this number high, for maximum performance.

#

MaxKeepAliveRequests 100
