基于域名虚拟主机及主站迁移

第二章实验（二）：基于域名虚拟主机及主站迁移
1.配置BIND支持多域名解析：在实际工作中需要申请多个域名，并做好解析。
登录到192.168.100.100（已经提供了linuxfan.cn的解析）
[root@ns ~]# vim /var/named/chroot/etc/named.conf ##在该文件末尾添加如下内容
zone "sggfu.com" IN {
type master;
file "sggfu.com.zone";
};
:wq



[root@ns ~]# vim /var/named/chroot/var/named/sggfu.com.zone ##新建区域数据文件
$TTL 86400
@ IN SOA sggfu.com. root.sggfu.com. (
20150630
1H
2M
3W
1D
)
@ IN NS ns.sggfu.com.
@ IN A 192.168.100.100
ns IN A 192.168.100.100
www IN A 192.168.100.150
:wq



[root@ns ~]# vim /var/named/chroot/var/named/sggfu.com.zone ##新建区域数据文件
$TTL 86400
@ IN SOA sggfu.com. root.sggfu.com. (
20150630
1H
2M
3W
1D
)
@ IN NS ns.sggfu.com.
@ IN A 192.168.100.100
ns IN A 192.168.100.100
www IN A 192.168.100.150
:wq



[root@ns ~]# /etc/init.d/named restart ##重启服务
[root@ns ~]# nslookup
> server 192.168.100.100
Default server: 192.168.100.100
Address: 192.168.100.100#53
> www.sggfu.com
Server:192.168.100.100
Address:192.168.100.100#53

Name:www.sggfu.com ##解析成功
Address: 192.168.100.150
> www.linuxfan.cn
Server:192.168.100.100
Address:192.168.100.100#53

Name:www.linuxfan.cn
Address: 192.168.100.150
> exit

[root@ns ~]#



2.配置基于域名的虚拟主机：登录到192.168.100.150上
1)设置虚拟主机站点的网页根目录：（测试数据）
[root@www ~]# cd /usr/local/httpd/htdocs/
[root@www ~]# mkdir linuxfan
[root@www ~]# mkdir sggfu
[root@www ~]# echo "www.linuxfan.cn" >>linuxfan/index.html
[root@www ~]# echo "www.sggfu.com" >>sggfu/index.html
2)修改虚拟主机配置文件：
[root@www ~]# vim /usr/local/httpd/conf/httpd.conf
387 Include conf/extra/httpd-vhosts.conf ##去掉该行的注释
388
:set nu 388,0-1 88%
:wq



[root@www ~]# cd /usr/local/httpd/conf/extra/ ;ls



[root@www extra]# cp httpd-vhosts.conf httpd-vhosts.conf.bak ##备份配置文件，养成
好习惯



[root@www ~]# vim /usr/local/httpd/conf/extra/httpd-vhosts.conf ##修改配置文件如下

NameVirtualHost 192.168.100.150:80
<VirtualHost 192.168.100.150:80>
ServerAdmin admin@linuxfan.cn
DocumentRoot "/usr/local/httpd/htdocs/linuxfan"
ServerName www.linuxfan.cn
ErrorLog "logs/www.linuxfan.cn-error_log"
CustomLog "logs/www.linuxfan.cn-access_log" combined
</Virtualhost>
<VirtualHost 192.168.100.150:80>
ServerAdmin admin@sggfu.com
DocumentRoot "/usr/local/httpd/htdocs/sggfu/"
ServerName www.sggfu.com
ErrorLog "logs/www.sggfu.com-error_log"
CustomLog "logs/www.sggfu.com-access_log" combined
</VirtualHost>
:wq



3)测试：虚拟主机（登录到192.168.100.100）
[root@ns ~]# vim /etc/resolv.conf ##编辑配置文件确认如下行
[root@ns ~]# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
nameserver 192.168.100.100 ##添加该行
nameserver 192.168.1.1



[root@ns ~]# elinks --dump www.linuxfan.cn ##访问成功
www.linuxfan.cn




[root@ns ~]# elinks --dump www.sggfu.com ##访问成功
www.sggfu.com




windows主机用浏览器访问： http://www.linuxfan.cn href="http://s1.51cto.com/wyfs02/M02/8A/AC/wKiom1g21tzTSdLpAADprdHPAUQ976.png-wh_500x0-wm_3-wmp_4-s_2385157484.png" target=_blank>


http://www.sggfu.com


http://www.linuxfan.cn/aws.html ##无法访问



3.主站迁移：
目前虚拟主机测试已经成功，问题在于老站www.linuxfan.cn中的web依然需要提供，下面将完成主站迁移，实现旧资源依然能访问：
1)移动老站资源：
[root@www ~]# tree /usr/local/httpd/htdocs/ ##树形结构查看网页根目录下的内容
/usr/local/httpd/htdocs/
├── aws.html
├── index.html
├── linuxfan
│ └── index.html
└── sggfu
└── index.html

2 directories, 4 files



[root@www ~]# cd /usr/local/httpd/htdocs/
[root@www htdocs]# ls
aws.html index.html linuxfan sggfu
[root@www htdocs]# mv aws.html index.html linuxfan/ ##将所有老站的内容移动到新站目录下
mv：是否覆盖"linuxfan/index.html"？ y
[root@www htdocs]#



2)修改配置文件：
[root@www ~]# vim /usr/local/httpd/conf/httpd.conf ##注释掉主配置文件中关于awstats的配置
413 #Alias /awstatsclasses "/usr/local/awstats/wwwroot/classes/"
414 #Alias /awstatscss "/usr/local/awstats/wwwroot/css/"
415 #Alias /awstatsicons "/usr/local/awstats/wwwroot/icon/"
416 #ScriptAlias /awstats/ "/usr/local/awstats/wwwroot/cgi-bin/"
417 #
418 ##
419 ## This is to permit URL access to scripts/files in AWStats directory.
420 ##
421 #<Directory "/usr/local/awstats/wwwroot">
422 # Options None
423 # AllowOverride None
424 # Order allow,deny
425 # Allow from 192.168.100.110
426 # AuthType Basic
427 # AuthName "Log analysis system"
428 # AuthBasicProvider file
429 # AuthUserFile /usr/local/httpd/conf/htpasswd
430 # AuthGroupFile /usr/local/httpd/conf/htgroups
431 # Require group mygroup
432 #</Directory>
433 #



:413,$ s/^/#/g
:wq
[root@www ~]# vim /usr/local/httpd/conf/extra/httpd-vhosts.conf ##修虚拟主机配置文件，将主配置文件中注释掉的配置文件项复制到第一个虚拟配置区域内

Alias /awstatsclasses "/usr/local/awstats/wwwroot/classes/"
Alias /awstatscss "/usr/local/awstats/wwwroot/css/"
Alias /awstatsicons "/usr/local/awstats/wwwroot/icon/"
ScriptAlias /awstats/ "/usr/local/awstats/wwwroot/cgi-bin/"

<Directory "/usr/local/awstats/wwwroot">
Options None
AllowOverride None
Order allow,deny
Allow from 192.168.100.110
AuthType Basic
AuthName "Log analysis system"
AuthBasicProvider file
AuthUserFile /usr/local/httpd/conf/htpasswd
AuthGroupFile /usr/local/httpd/conf/htgroups
Require group mygroup
</Directory>
:wq



[root@www ~]# /etc/init.d/httpd restart ##重启服务
httpd is restart complete.



[root@www ~]# vim /etc/awstats/awstats.www.linuxfan.cn.conf ##修改第50行如下
LogFile="/usr/local/httpd/logs/www.linuxfan.cn-access_log"
:wq



[root@www ~]# /usr/local/awstats/tools/awstats_updateall.pl now

访问测试：
192.168.100.100上：测试成功
[root@ns ~]# elinks --dump www.linuxfan.cn
