The configuration commands of the Apache server are not divided into three concentrated parts.

The configuration commands of the Apache server are not divided into three concentrated parts.

1. Configure the environment variables of the Apache server throughout the running process.

2. Configure the detailed interface parameters for the master server or default server.

3. Set the virtual server so that Web requests with different IP addresses or different host names can be completed on the same Apache server.

(That is, a physical server can be set to a virtual server with multiple IP addresses or multiple host names)

Part 1: Environment Settings

# Set the server startup mode: standalone or inetd.

# If a problem or error occurs, you can configure Apache for four responses.
#1. Output custom (mizmized) messages (text)
# Errordocument 500 "the server made a boo.
#2. re-import a local URL to solve this problem/Error
# Errordocument 404/missing.html
# Errordocument 404/cgi-bin/missing_handler.pl
#3. re-import to an external URL to handle this issue/Error
# Errordocument 402 http://some.other _ server.com/subscription_info.html

3. Set virtual web

IP-type VM

An IP host is the unique IP address of each VM. Multi-IP, so
Laris2.5 and Windows NT both support this method.
You can configure multiple VM instances in either of the following ways:

1. Start an httpd process for each VM.
Use this method in the following cases:
1) Security Isolation needs to be considered, for example, two httpd run on different users, groups, listen, serverroot, and two
Users cannot access other data except browsing data through the Web.
2) provides sufficient memory and file descriptors.
Setting method:
Create an independent httpd installation for each virtual host. In the configuration file httpd. conf of each installation path, use
The listen command specifies the IP address of the process service, for example, listen 10.68.37.10: 80.

2. Start an httpd process for all virtual hosts.
Use this method in the following cases:
1) allows sharing httpd configurations between virtual hosts.
2) computers serve a large number of requests and run multiple processes to reduce server performance.
Setting method:
In the configuration file httpd. conf, use the virtualhost command to set serveradmin and serverna for each virtual host.
Me, DocumentRoot, errorlog, transferlog, or customlog, for example:
<Virtualhost www.smallco.com> # IP address is recommended here
Serveradmin webmaster@mail.smallco.com
DocumentRoot/usr/local/etc/httpd/htdocs/smallco
Servername www.smallco.com # we recommend that you use a domain name here
Errorlog/usr/local/etc/httpd/logs/smallco/error_log
Transferlog/usr/local/etc/httpd/logs/smallco/access_log
</Virtualhost> 〉
<Virtualhost www.baygroup.org> # IP address is recommended here
Serveradmin webmaster@mail.baygroup.org
DocumentRoot/groups/baygroup/WWW
Servername www.baygroup.org # domain names are recommended here
Errorlog/groups/baygroup/logs/error_log
Transferlog/groups/baygroup/logs/access_log
</Virtualhost> 〉
At the same time, you need to configure the virtual network port or network card, and configure the corresponding settings in DNS.

Name-based VM (supported by apache1.3 or later versions)
Although the IP type VM is good, it is not the best solution. It requires that each VM has a dedicated IP address on some machines.
Difficult to implement. A name-based VM has different names, but the IP address is the same. Its advantage is that it is unlimited.
The number of virtual hosts, which is easy to configure and use without additional hardware and software. The disadvantage is that the client must support this part of the Protocol,
Browsers of the latest version are supported, but some earlier versions are not supported. However, Apache provides a solution for this.
Setting method:
In the configuration file httpd. conf, use the namevirtualhost command to set the virtual host, for example:
Namevirtualhost 111.22.33.44
<Virtualhost 111.22.33.44> # IP address is recommended.
Servername www. domain. TLD # domain name is recommended here
DocumentRoot/web/Domain
</Virtualhost> 〉
At the same time, the DNS defines www. domain. TLD pointing to 111.22.33.44.
Note: When the IP address is used after the namevirtualhost command, any URL request using the IP address is for the VM,
The master server will never respond to a URL request using an IP address. In addition, some servers want to be accessed by multiple names. Example
For example, if a server with an IP address wants to be accessed by domain. TLD and www2.domain. TLD
The virtualhost command uses the serveralias command. For example, serveralias domain. TLD *. domain. TLD
Additional VM configuration instances are provided.
　
　
Appendix: VM instance settings
IP-type VM Configuration
Setup 1: the server has two IP addresses,
111.22.33.44 server. domain. TLD
111.22.33.55 www. otherdomain. TLD
Www. domain. TLD is the alias of server. domain. TLD (cname), representing the master server.
Server Configuration:
...
Port 80
DocumentRoot/www/Domain
Servername www. domain. TLD
<Virtualhost 111.22.33.55> 〉

Setup 3: the server has two IP addresses,
111.22.33.44 server. domain. TLD
111.22.33.55 www-cache.domain.tld
Www. domain. TLD is the alias of server. domain. TLD (cname), representing the master server.
The www-cache.domain.tld is the proxy-cache, the port is 8080, and the Web server uses the default 80.
