# 编辑本地DNS
vim /etc/hosts

# 添加多域名的记录
192.168.136.140 www1.example.com www2.example.com

# 添加 Name-Based 虚拟主机块配置
vim /etc/httpd/conf/httpd.conf

## Name-Based ####################################################
<VirtualHost *:80>
    # This first-listed virtual host is also the default for *:80 第一个虚拟主机为默认主机
    ServerName www1.example.com
    ServerAlias example1.com
    DocumentRoot "/var/www/vhosts/www1"
</VirtualHost>

<VirtualHost *:80>
    ServerName www2.example.com
    #ServerAlias example2.com

# 检查配置语法 *:80    is a NameVirtualHost 这里能正常解析，语法OK
