Three ways Apache configures a virtual host

1 Apache virtual hosts are implemented in 3 ways.

• IP-based virtual host
• Port-based virtual host
• Domain-based virtual host

2.1 Enabling Virtual Host preparation

2.1.1 Installation httpd

Yum Install httpd-y

2.1.2 Disabling the default host mode

[Email protected] httpd]# vim/etc/httpd/conf/"/var/www/html"

2.2 IP-based virtual host configuration

2.2.1 Adding multiple IPs to the host

[Email protected] conf.d]# IP addr Show dev eth0 #查看原有IP
2:eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> MTU Qdisc pfifo_fast State up Qlen 1000
Link/ether 00:0c:29:77:77:7d BRD FF:FF:FF:FF:FF:FF
inet 192.168.137.200/24 BRD 192.168.137.255 Scope Global eth0
Inet6 FE80::20C:29FF:FE77:777D/64 Scope link
Valid_lft Forever Preferred_lft Forever
[Email protected] conf.d]# IP addr add 192.168.137.201/24 dev eth0 #添加一个IP
[[Email protected] conf.d]# IP addr Show dev eth0 #查看添加后的IP信息, at this time there are 2 IP addresses. 200,201
2:eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> MTU Qdisc pfifo_fast State up Qlen 1000
Link/ether 00:0c:29:77:77:7d BRD FF:FF:FF:FF:FF:FF
inet 192.168.137.200/24 BRD 192.168.137.255 Scope Global eth0
inet 192.168.137.201/24 Scope Global secondary eth0
Inet6 FE80::20C:29FF:FE77:777D/64 Scope link
Valid_lft Forever Preferred_lft Forever

2.2.2 Adding a virtual host configuration file

[Email protected] conf.d]# cd/etc/httpd/conf.d/#进入配置目录[[ Email protected] conf.d]# vim virtualhost.conf #创建一个配置文件, edit content as follows [[email protected] conf.d]#Catvirtualhost.conf #查看并检查配置文件<virtualhost192.168.137.200: the>DocumentRoot"/var/www/test200"ServerName www.test200.com</virtualhost><virtualhost192.168.137.201: the>DocumentRoot"/var/www/test201"ServerName www.test201.com</VirtualHost>

[Email protected] conf.d]# cd/var/www            mkdir  test200 test201    #创建目录   echo test200 >>./test200/echo#创建IP为200的主页

2.2.3 Test

[Email protected] www]# service httpd restart
stopping httpd: [OK]
Starting httpd:httpd:Could not reliably determine the server ' s fully qualified domain name, using Localhost.localdomain For ServerName
[OK]
We use ELinks for testing, of course, the same as the browser test [[email protected] conf]# ELinks-source192.168.137.200Test200[[email protected] conf]# elinks-source192.168.137.201test201

2.3 Port-based virtual host configuration

2.3.1 Adding a listening port to the master profile

[Email protected] conf]# vim/etc/httpd/conf/8080

2.3.2 Adding a 8080 port virtual configuration

[Email protected] conf.d]#Catvirtualhost.conf<virtualhost192.168.137.200: the>DocumentRoot"/var/www/test200"ServerName www.test200.com</virtualhost><virtualhost192.168.137.201: the>DocumentRoot"/var/www/test201"ServerName www.test201.com</VirtualHost> #下面的内容是在上面的配置的基础上添加的.<virtualhost 192.168.137.201:8080> documentroot "/var/www/test201-8080" ServerName www.test201-8080.com& Lt;/virtualhost>

[Email protected] conf.d]# cd/var/www/           #切换目录 mkdir test201-8080        #创建目录  Echo " test201-8080 " >>./test201-8080/index.html       #创建主页

2.3.2 Test

[ [email protected] www]# service httpd restartstopping httpd: [OK]sta Rting httpd:httpd:Could not reliably determine the server's fully qualified domain name, using Localhost.localdomain for ServerName[OK][[email protected] conf]# elinks-source192.168.137.201: theTest201[[email protected] conf]# elinks-source192.168.137.201Test201[[email protected] conf]# elinks-source192.168.137.201:8080test201-8080

2.4 Domain-based virtual host configuration

2.4.1 Adding a domain name to the virtual host configuration

[ email protected] conf.d]# vim virtualhost.conf #编辑虚拟主机配置文件 [[email protected] conf.d]#Catvirtualhost.conf #内容如下, the red part is added on the basis above namevirtualhost 192.168.137.200:80 <virtualhost192.168.137.200: the>DocumentRoot"/var/www/test200"ServerName www.test200.com</VirtualHost><virtualhost 192.168.137.200:80> documentroot "/var/www/test200net" ServerName www.test200.net</ Virtualhost><virtualhost192.168.137.201: the>DocumentRoot"/var/www/test201"ServerName www.test201.com</virtualhost><virtualhost192.168.137.201:8080>DocumentRoot"/var/www/test2018080"ServerName www.test2018080.com</VirtualHost>

[[email protected] conf.d]#! serservice httpd restartstopping httpd:                                            [  OK  ]starting httpd:httpd:Could not reliably determine the server's fully qualified domain name, using Localhost.localdomain for ServerName                                                           [  OK  ]   

[Email protected] conf.d]# cd/var/www            mkdir  test200net          Echo " test200net " >>./test200net/index.html  #创建主页

2.4.2 Test

2.4.2.1 adding domain name resolution

Here we do not provide DNS to parse, simple to use the Hosts file area resolution on it.

[Email protected] www]# vim/etc/hosts      cat /etc/hosts127.0.  0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4::1          localhost localhost.localdomain localhost6 localhost6.localdomain6192.168. 137.200 www.test200.com 192.168. 137.200 www.test200.net

Then you can test it.

[[email protected] www]# Elinks-source http://www.test200.com       #测试. com domain  -source http: // www.test200.net       #测试. NET domain test200net
