基于IP的虚拟主机配置

基于IP的虚拟主机————就是说每个虚拟主机使用一个独立的IP地址
服务器配置多块网卡实现，或者同一块网卡配置多个IP实现都可以
今天模拟的环境是同一网卡配置多个IP地址实现基于IP的虚拟主机配置

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上新增一个IP地址用于测试使用

[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：联通性测试

在本地客户端主机上测试联通性

C:\Users\Administrator>ping 192.168.1.20
正在 Ping 192.168.1.20 具有 32 字节的数据:
来自 192.168.1.20 的回复: 字节=32 时间来自 192.168.1.20 的回复: 字节=32 时间来自 192.168.1.20 的回复: 字节=32 时间来自 192.168.1.20 的回复: 字节=32 时间192.168.1.20 的 Ping 统计信息:
数据包: 已发送 = 4，已接收 = 4，丢失 = 0 (0% 丢失)，
往返行程的估计时间(以毫秒为单位):
最短 = 0ms，最长 = 0ms，平均 = 0ms

三：备份虚拟主机配置文件

提示：生产环境一定要养成良好的习惯

[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：配置虚拟主机配置文件

[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
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 block.
#

ServerAdmin admini@abc.com
DocumentRoot "/data/www/bbs"
ServerName 192.168.1.20
ServerAlias abc.com
ErrorLog "logs/bbs-error_log"
CustomLog "logs/bbs-access_log" common

上面的标记部分为修改的配置

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

发现httpd服务并没有开机自启动

检查发现/etc/init.d/下没有httpd服务

[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

因此编辑下面的文件，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 加入启动
[root@Centos init.d]# chkconfig --list httpd 查看启动情况
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：测试访问

[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

打开本地客户端浏览器

经测试表示之前的配置是正确的，同样的方法可以配置多个基于IP的虚拟主机
