Apache Build virtual Host (based on IP, port, domain name implementation) enclosing the source package

Brief introduction

Virtual host refers to a certain amount of disk space on the network server, the administrator can take advantage of this part of the space, put the site and application components, provide the necessary data storage and transmission functions. A virtual host is one that divides a physical server running on the Internet into multiple "virtual" servers.

Advantages

Low price. Compared to the purchase of a standalone server, the cost of website construction is greatly reduced, providing a great convenience for the popularization of small and medium-sized websites.
Improve efficiency. Because multiple virtual hosts share the resources of a real host, it greatly increases the utilization of the server and bandwidth, which makes it possible to configure multiple network IP addresses on a single server without conflict.

Disadvantages

Functional limitations. For example, may consume the system resources of the Forum program, traffic statistics function.
Access speed and traffic limits. The different virtual hosts on a single server are separate and managed by the administrator. However, a server host can only support a certain number of virtual hosts, and when this amount is exceeded, the server performance drops sharply.
The independence of the poor. Virtual host can not be arbitrarily installed by the customer software and Remote Desktop and other operations.

Use

Suitable as small and medium-sized web portal, save money resources.
Small and medium-sized enterprises, professional portals can use virtual host space to provide data sharing, data download services.
can provide the data storage data function for the SME. Because the cost is lower than the standalone server, high security is preferred as a small database.
The application templates that are unique to the virtual host space allow users to quickly deploy in batches and are the preferred platform for small and midsize businesses to run ASP or PHP applications.

Experimental environment

• System Environment: centos6.5
• Server IP Address: 192.168.100.103
• Client IP Address: 192.168.100.99
• Yum Mount directory:/mnt/sr0
• Related source package: Baidu Cloud download? Password: PKO3

Build step one, prepare for work 1, close the firewall and SELinux

[Email protected] ~]# chkconfig iptables off #随开机关闭iptables
[Email protected] ~]# Vim/etc/sysconfig/selinux

[email protected] ~]# reboot #重启Linux生效

Second, build the DNS server 1, install the BIND package

[Email protected] ~]# cd/mnt/sr0/packages/
[Email protected] packages]# RPM-IVH bind-9.8.2-0.17.rc1.el6_4.6.x86_64.rpm

2. Modify the master configuration file named.conf

[Email protected] ~]# vim/etc/named.conf

3. Create and modify the DNS forward parsing file

[Email protected] ~]# cd/var/named/
[Email protected] named]# cp-p named.localhost bt.com.zone #将模板文件改为正向解析文件进行修改
[Email protected] ~]# Vim/var/named/bt.com.zone #修改正向解析文件

[Email protected] named]# cp-p bt.com.zone cloud.com.zone #搭建cloud域
[Email protected] ~]# Vim/var/named/bt.com.zone

4. Start the DNS server

[[email protected] ~]#/etc/init.d/named start

5. Modify the DNS client configuration file

[Email protected] ~]# echo "nameserver 192.168.100.103" >>/etc/resolv.conf

6. Test DNS resolution

[[email protected] ~]# nslookup www.bt.com #nslookup used to query DNS records to see if the domain name resolution is normal
[email protected] ~]# nslookup www.cloud.com

Third, install Apache1, install GCC, gcc-c++, make, ARP, Arp-util, Pcre and other toolkits

[Email protected] ~]# yum-y install gcc gcc-c++ make #安装C语言编译器以及make

[Email protected] ~]# TAR-ZXVF apr-1.4.6.tar.gz-c/usr/src/
[Email protected] ~]# cd/usr/src/apr-1.4.6/
[[email protected] apr-1.4.6]#./configure prefix=/usr/local/apr && make && make install

[Email protected] ~]# TAR-ZXVF apr-util-1.4.1.tar.gz-c/usr/src/
[Email protected] ~]# CD/USR/SRC/APR-UTIL-1.4.1/
[Email protected] apr-util-1.4.1]#/configure prefix=/usr/local/apr-util--with-apr=/usr/local/apr && Make & amp;& make Install

[Email protected] ~]# TAR-ZXVF pcre-8.10.tar.gz-c/usr/src #支持正则
[Email protected] ~]# cd/usr/src/pcre-8.10/
[Email protected] pcre-8.10]#/configure prefix=/usr/local/pcre && make && make instal

2. Configuring and installing Apache

[Email protected] ~]# tar xvfz httpd-2.4.2.tar.gz-c/usr/src/
[Email protected] ~]# cd/usr/src/httpd-2.4.2/
[Email protected] httpd-2.4.2]#/configure \
--PREFIX=/USR/LOCAL/HTTPD \
--WITH-APR=/USR/LOCAL/APR \
--with-pcre=/usr/local/pcre \
--ENABLE-SO \
--enable-rewrite \
--enable-mods-shared=most \
--with-mpm=worker \
--disable-cgid \
--disable-cgi

Parameter resolution:
Prefix: Specifying the installation directory
installation directory for WITH-APR:APR
With-pcre: Using the extended pcre regular expression Library
ENABLE-SO: Enable dynamic load module support, what functions are required to dynamically load
Enable-rewrite: Enable Web address rewriting to implement pseudo-static
Enable-mods-shared: Enabled shared DSO module
WITH-MPM: Select the processing module that Apache uses
Disable-cgid: Disable Cgid
DISABLE-CGI: Enable CGI script support (Universal Gateway Interface)

[[email protected] httpd-2.4.2]# make && make install

3. Adding system Services

[Email protected] ~]# CP/USR/LOCAL/HTTPD/BIN/APACHECTL/ETC/INIT.D/HTTPD

[Email protected] ~]# VIM/ETC/INIT.D/HTTPD

Lines 2nd, 32 add the following parameters

Listen 192.168.100.103:80 #监听本地IP

6. Restart Service, test

[[Email protected] ~]# service httpd start

Four, domain-based virtual host (same IP, same port, different hostname) 1, create virtual Web host Site Directory and Web page

[Email protected] ~]# mkdir-p/var/www/html/{btcom,cloudcom} #创建网站目录
