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<1ms TTL=64

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.

192.168.1.20:80>

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
