Apache deploys three virtual host configurations based on IP address, port, and DNS domain name

1. Apache directory structure
Service directory: /usr/local/httpd
Main configuration file: /usr/local/httpd/confi/http.conf
Web page directory: /usr/local/httpd/htdocs
Service script: /usr/local/httpd /bin/apachectl
execution program: /usr/local/httpd/bin/httpd
Access log: /usr/local/httpd/log/access.log
Error log: /usr/local/httpd/log/error.log
2. Commonly used Global configuration parameters
ServerRoot: Service directory
ServerAdmin: Administrator email
User: User identity for running the service
Group: Group identity for running the service
ServerName: Domain name of the website server
DocumentRoot: Root directory of the web document
Listen: Monitoring IP address, port number
PidFile : The file that saves the PID number of the http process
DirectoryIndex: The default index page file
ErrorLog: The location of the error log file
CustomLog: The location of the access log file
LogLevel: The level of recording qualifications, the default is warn
Timeout: The network connection timeout, the default is 300 seconds
KeepAlive :Whether to maintain the connection, optional On or Off
MaxKeepAliveRequests: The maximum number of requested files per connection status
KeepAliveTimeout: The timeout period to keep the connection
Include: Other configuration files that need to be included
3. Compile and install httpd

3.1 Preparation

Check if httpd is installed
rpm -qa httpd
Uninstall the original httpd
rpm -e httpd

3.2 Compile and install environment

[root@xss httpd-2.2.15]# yum -y install gcc gcc-c++

3.3 Source code compilation and installation

解包：[root@xss httpd-2.2.15]# tar zxf httpd-2.2.15.tar.gz -C /usr/src/

Configuration : [root@xss httpd-2.2.15]# cd /usr/src/httpd-2.2.15/

[root@xss httpd-2.2.15]# ./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-charset-lite --enable-cgi --with-included-apr

Compile and install : [root@xss httpd-2.2.15]# make && make install

3.4 Optimizing the Execution Path

[root@xss httpd-2.2.15]# ln -s /usr/local/httpd/bin/* /usr/local/bin
[root@xss httpd-2.2.15]# httpd -v = /usr/local/ httpd/bin/httpd – Insert image description here
3.5 Add httpd system service

[root@xss httpd-2.2.15]# cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
[root@xss httpd-2.2.15]# vim /etc/init.d/httpd
#!/bin/sh
#chkconfig:35 85 15 //Which Linux levels need to start httpd(3,5); startup sequence number (85); shutdown sequence number (15)
#description:startup for httpd server
Insert image description here
startup

[root@xss httpd-2.2.15]# chkconfig --add httpd

Start httpd service

[root@xss httpd-2.2.15]# service httpd start

4.3 Virtual host based on DNS domain name

Install bind service
[root@xss Packages]# rpm -ivh bind-9.8.2-0.17.rc1.el6_4.6.x86_64.rpm
configure DNS

Modify main configuration file

Declare two domain
options { directory “/var/named”; };

zone “mytest1.com” IN{
type master;
file “mytest1.com.zone”;

};

zone “mytest2.com” IN{
type master;
file “mytest2.com.zone”;

};

write parsing file,

restart service
, modify virtual host configuration file

[root@xss htdocs]# vim /usr/local/httpd/conf/extra/httpd-vhosts.conf

Statement 192.168.8.138 is a virtual host server based on domain name
