基于多主机的Web服务

【Centos7.4版本】

！！！测试环境我们首关闭防火墙和selinux

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
[root@localhost ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
[root@localhost ~]# setenforce 0

一、基于多主机的Web服务

1、首先先看一下本地网卡的信息

[root@localhost ~]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# cat ifcfg-ens32
    TYPE=Ethernet
    PROXY_METHOD=none
    BROWSER_ONLY=no
    BOOTPROTO=none
    IPADDR=10.0.0.129        //我本机主网卡P地址
    NETMASK=255.255.255.0
    GATEWAY=10.0.0.2
    DNS1=8.8.8.8
    DEFROUTE=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_FAILURE_FATAL=no
    IPV6_ADDR_GEN_MODE=stable-privacy
    NAME=ens32
    UUID=e4b11756-1775-4b6a-adbf-95f3f24f941e
    DEVICE=ens32
    ONBOOT=yes  

2、安装HTTP服务，并启动服务

[root@localhost ~]# yum install -y httpd
[root@localhost ~]# systemctl start httpd
[root@localhost ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

3、首先看一下配置模板

[root@localhost ~]# vim /usr/share/doc/httpd-2.4.6/httpd-vhosts.conf
..........                //上面的我省略了
<VirtualHost *:@@Port@@>
    ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "@@ServerRoot@@/docs/dummy-host.example.com"
    ServerName dummy-host.example.com
    ServerAlias www.dummy-host.example.com
    ErrorLog "/var/log/httpd/dummy-host.example.com-error_log"
    CustomLog "/var/log/httpd/dummy-host.example.com-access_log" common
</VirtualHost>

<VirtualHost *:@@Port@@>
    ServerAdmin webmaster@dummy-host2.example.com
    DocumentRoot "@@ServerRoot@@/docs/dummy-host2.example.com"
    ServerName dummy-host2.example.com
    ErrorLog "/var/log/httpd/dummy-host2.example.com-error_log"
    CustomLog "/var/log/httpd/dummy-host2.example.com-access_log" common
</VirtualHost>
//这几行是配置虚拟主机的模板

4、创建目录，写入测试首页

[root@localhost ~]# mkdir /var/www/aaa
[root@localhost ~]# mkdir /var/www/bbb
[root@localhost ~]# echo '<h1>This servername is aaa.test.com</h1>' > /var/www/aaa/index.html
[root@localhost ~]# echo '<h1>This servername is bbb.test.com</h1>' > /var/www/bbb/index.html

5、在本地的/etc/hosts文件下写入两个hostname

[root@localhost ~]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.129      aaa.test.com
10.0.0.129      bbb.test.com
//最后两条需要手动添加

6、编辑HTTP的配置文件，添加以下内容

[root@localhost ~]# vim /etc/httpd/conf/httpd.conf
..........                //上面的我就省略
<VirtualHost 10.0.0.129:80>
        documentroot    "/var/www/aaa"
        servername      "aaa.test.com"
        ErrorLog        "/var/log/httpd/aaa.test.com-error_log"
        CustomLog       "/var/log/httpd/aaa.test.com-access_log" common
</VirtualHost>
<VirtualHost 10.0.0.129:80>
        documentroot    "/var/www/bbb"
        servername      "bbb.test.com"
        ErrorLog        "/var/log/httpd/bbb.test.com-error_log"
        CustomLog       "/var/log/httpd/bbb.test.com-access_log" common
</VirtualHost>
//在文件的最后添加上面的内容

7、重启HTTP服务

[root@localhost ~]# systemctl restart httpd

8、在本地C盘的C:WindowsSystem32driversetchosts这个文件添加两行内容

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#    127.0.0.1       localhost
#    ::1             localhost

10.0.0.129        aaa.test.com
10.0.0.129        bbb.test.com
//添加最后两行就行

9、在浏览器的地址栏分别输入两个域名
