基於IP的虛擬主機配置

基於IP的虛擬主機————就是說每個虛擬主機使用一個獨立的IP地址
服務器配置多塊網卡實現，或者同一塊網卡配置多個IP實現都可以
今天模擬的環境是同一網卡配置多個IP地址實現基於IP的虛擬主機配置

一：新增IP地址

[root@Centos ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0C:29:AA:CA:2B
inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:feaa:ca2b/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2345 errors:0 dropped:0 overruns:0 frame:0
TX packets:694 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:224750 (219.4 KiB) TX bytes:92020 (89.8 KiB)

在eth0上新增一個IP地址用於測試使用

[root@Centos ~]# ifconfig eth0:20 192.168.1.20 netmask 255.255.255.0 up
[root@Centos ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:AA:CA:2B
inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:feaa:ca2b/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2468 errors:0 dropped:0 overruns:0 frame:0
TX packets:767 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:235882 (230.3 KiB) TX bytes:100158 (97.8 KiB)

eth0:20 Link encap:Ethernet HWaddr 00:0C:29:AA:CA:2B
inet addr:192.168.1.20 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

二：聯通性測試

在本地客戶端主機上測試聯通性

C:\Users\Administrator>ping 192.168.1.20
正在 Ping 192.168.1.20 具有 32 字節的數據:
來自 192.168.1.20 的回覆: 字節=32 時間<1ms TTL=64
來自 192.168.1.20 的回覆: 字節=32 時間<1ms TTL=64
來自 192.168.1.20 的回覆: 字節=32 時間<1ms TTL=64
來自 192.168.1.20 的回覆: 字節=32 時間<1ms TTL=64
192.168.1.20 的 Ping 統計信息:
數據包: 已發送 = 4，已接收 = 4，丟失 = 0 (0% 丟失)，
往返行程的估計時間(以毫秒爲單位):
最短 = 0ms，最長 = 0ms，平均 = 0ms

三：備份虛擬主機配置文件

提示：生產環境一定要養成良好的習慣

[root@Centos ~]# cd /application/apache/conf/extra/
[root@Centos extra]# cp httpd-vhosts.conf httpd-vhosts.conf.$(date +%F)
[root@Centos extra]# ls -ll
total 76
-rw-r--r--. 1 root root 2895 Sep 12 03:30 httpd-autoindex.conf
-rw-r--r--. 1 root root 1852 Sep 12 03:30 httpd-dav.conf
-rw-r--r--. 1 root root 2942 Sep 12 03:30 httpd-default.conf
-rw-r--r--. 1 root root 1119 Sep 12 03:30 httpd-info.conf
-rw-r--r--. 1 root root 5078 Sep 12 03:30 httpd-languages.conf
-rw-r--r--. 1 root root 1039 Sep 12 03:30 httpd-manual.conf
-rw-r--r--. 1 root root 4444 Sep 12 03:30 httpd-mpm.conf
-rw-r--r--. 1 root root 2243 Sep 12 03:30 httpd-multilang-errordoc.conf
-rw-r--r--. 1 root root 13506 Sep 12 03:30 httpd-ssl.conf
-rw-r--r--. 1 root root 694 Sep 12 03:30 httpd-userdir.conf
-rw-r--r--. 1 root root 1037 Sep 13 06:35 httpd-vhosts.conf
-rw-r--r--. 1 root root 1481 Sep 13 06:28 httpd-vhosts.conf.2016-09-13
-rw-r--r--. 1 root root 1037 Sep 15 02:04 httpd-vhosts.conf.2016-09-15
-rw-r--r--. 1 root root 3161 Sep 12 03:30 proxy-html.conf

四：配置虛擬主機配置文件

[root@Centos extra]# vi httpd-vhosts.conf
Virtual Hosts

Required modules: mod_log_config

If you want to maintain multiple domains/hostnames on your
machine you can setup VirtualHost containers for them. Most configurations
use only name-based virtual hosts so the server doesn't need to worry about
IP addresses. This is indicated by the asterisks in the directives below.

Please see the documentation at
<URL:http://httpd.apache.org/docs/2.4/vhosts/>;
for further details before you try to setup virtual hosts.

#You may use the command line option '-S' to verify your virtual host
configuration.

VirtualHost example:
Almost any Apache directive may go into a VirtualHost container.
The first VirtualHost section is used for all requests that do not
match a ServerName or ServerAlias in any <VirtualHost> block.
#
<VirtualHost 192.168.1.20:80>
ServerAdmin [email protected]
DocumentRoot "/data/www/bbs"
ServerName 192.168.1.20
ServerAlias abc.com
ErrorLog "logs/bbs-error_log"
CustomLog "logs/bbs-access_log" common
</VirtualHost>

上面的標記部分爲修改的配置

[root@Centos extra]# ../../bin/apachectl graceful
httpd not running, trying to start

發現httpd服務並沒有開機自啓動

檢查發現/etc/init.d/下沒有httpd服務

[root@Centos extra]# cd /etc/init.d/
[root@Centos init.d]# ls
abrt-ccpp crond killall ntpd rpcgssd sshd
abrtd cups lvm2-lvmetad ntpdate rpcidmapd sssd
abrt-oops dnsmasq lvm2-monitor oddjobd rpcsvcgssd sysstat
acpid firstboot mdmonitor portreserve rsyslog udev-post
atd functions messagebus postfix sandbox wdaemon
auditd haldaemon netconsole psacct saslauthd winbind
autofs halt netfs quota_nld single wpa_supplicant
blk-availability ip6tables network rdisc smartd ypbind
bluetooth iptables NetworkManager restorecond snmpd
certmonger irqbalance nfs rngd snmptrapd
cpuspeed kdump nfslock rpcbind spice-vdagentd
[root@Centos init.d]# cp /application/apache/bin/apachectl ./httpd

不支持chkconfig

[root@Centos init.d]# chkconfig --add httpd
service httpd does not support chkconfig

因此編輯下面的文件，增加如下配置

[root@Centos init.d]# vi /etc/init.d/httpd
#!/bin/sh
#
#chkconfig:345 85 15
#description:Start and stop the Apache HTTP Server
[root@Centos init.d]# chkconfig --add httpd 加入啓動
[root@Centos init.d]# chkconfig --list httpd 查看啓動情況
httpd 0:off 1:off 2:off 3:on 4:on 5:on 6:off
[root@Centos init.d]# cd -
/application/apache/conf/extra
[root@Centos extra]# ../../bin/apachectl -t
Syntax OK
[root@Centos extra]# ../../bin/apachectl graceful
[root@Centos extra]# lsof -i tcp:80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
httpd 2390 root 4u IPv6 16911 0t0 TCP :http (LISTEN)
httpd 2531 daemon 4u IPv6 16911 0t0 TCP
:http (LISTEN)
httpd 2532 daemon 4u IPv6 16911 0t0 TCP :http (LISTEN)
httpd 2533 daemon 4u IPv6 16911 0t0 TCP
:http (LISTEN)
[root@Centos extra]# ps -ef |grep httpd
root 2390 1 0 02:08 ? 00:00:00 /application/apache2.4.23/bin/httpd -k graceful
daemon 2531 2390 0 02:22 ? 00:00:00 /application/apache2.4.23/bin/httpd -k graceful
daemon 2532 2390 0 02:22 ? 00:00:00 /application/apache2.4.23/bin/httpd -k graceful
daemon 2533 2390 0 02:22 ? 00:00:00 /application/apache2.4.23/bin/httpd -k graceful
root 2623 1934 0 02:24 pts/1 00:00:00 grep httpd

五：測試訪問

[root@Centos extra]# echo '192.168.1.20:80 this server is the server of bbs stie'>>/data/www/bbs/index.html
[root@Centos extra]# cat /data/www/bbs/index.html
welcome to bbs.abc.com
192.168.1.20:80 this server is the server of bbs stie

打開本地客戶端瀏覽器

經測試表示之前的配置是正確的，同樣的方法可以配置多個基於IP的虛擬主機
