LAMP 和后面的LNMP 环境，不像前面的 Tomcat 环境一样，通常只用作一个web 项目。用的比较多的是，一个LAMP 或 LNMP 往往运行着多个 web 项目。这就需要使用到其虚拟主机配置了

16.3：配置虚拟主机

1、编辑apache 主配置文件 /usr/local/apache2/conf/httpd.conf，找到这一行： #Include conf/extra/httpd-vhosts.conf ，将前面的注释井号去掉，表启用虚拟主机配置：

Include conf/extra/httpd-vhosts.conf

2、编辑虚拟主机文件 /usr/local/apache2/conf/extra/httpd-vhosts.conf，将其默认的配置文件都注释掉，重新写配置，如下：

# 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 *:80>
#    ServerAdmin webmaster@dummy-host.example.com
#    DocumentRoot "/usr/local/apache2/docs/dummy-host.example.com"
#    ServerName dummy-host.example.com
#    ServerAlias www.dummy-host.example.com
#    ErrorLog "logs/dummy-host.example.com-error_log"
#    CustomLog "logs/dummy-host.example.com-access_log" common
#</VirtualHost>
#
#<VirtualHost *:80>
#    ServerAdmin webmaster@dummy-host2.example.com
#    DocumentRoot "/usr/local/apache2/docs/dummy-host2.example.com"
#    ServerName dummy-host2.example.com
#    ErrorLog "logs/dummy-host2.example.com-error_log"
#    CustomLog "logs/dummy-host2.example.com-access_log" common
#</VirtualHost>


<VirtualHost 192.168.137.101:80>
    ServerName test.apache.com
    DocumentRoot "/data/apache/website/test"
    CustomLog "logs/access.log" common
    ErrorLog "logs/error.log"
    <Directory "/data/apache/website/test">
        Options -Indexes
        AllowOverride ALL
        Require all granted
    </Directory>
</VirtualHost>

3、新建web 项目存放目录 /data/apache/website/test：

[root@centos ~]# mkdir -p /data/apache/website/test

4、在web 项目目录下创建测试文件 index.php，内容如下：

<?php

    echo $showtime=date("Y-m-d H:i:s");

?>

将其所属主合组都修改为 apache：

 [root@centos ~]# chown -R apache.apache /data/apache/

5、检查配置文件是否有误：

[root@centos ~]# /usr/local/apache2/bin/apachectl -t
Syntax OK

6、因为上面测试的脚本是输出系统当前时间，跟 php 有关，所以我们还要编辑 /usr/local/php/etc/php.ini 文件, 启用： ;date.timezone =:

 date.timezone = Asia/Shanghai

7、重载apache:

[root@centos ~]# systemctl reload httpd

8、测试访问（注：只能用 192.168.137.101这个IP或者本地hosts 做解析，使用域名 test.apache.com 访问）：
