ServerName outside VirtualHost mostly has cosmetic effect AFAIU, just 

put some canonical name of your server there.

Let's suppose a scene on centos7.

- domain name:  xyz.com
- the domain parsed by third-party dns server:   ns1.xxx.com
- IP address bound with domain:  123.123.123.123
- apache2 was installed on  123.123.123.123

It is the ServerName confused me.
### ServerName

In the `/etc/httpd/conf/httpd.conf`, `ServerName` gives the name and 

port that the server uses to identify itself. This can often be 

determined automatically, but we recommend you specify it explicitly 

to prevent problems during startup. If your host doesn't have a 

registered DNS name, enter its IP address here.

    #ServerName [url]www.example.com:80[/url]

Should my /etc/httpd/conf/httpd.conf be this way :

    config1:

    ServerRoot "/etc/httpd"
    Listen 80
    Include conf.modules.d/*.conf
    User apache
    Group apache
    ServerName 123.123.123.123:80
    <VirtualHost *:80>
        ServerName [url]www.xyz.com[/url]
        DocumentRoot "/var/www/html"
    </VirtualHost>

    config2:

    ServerRoot "/etc/httpd"
    Listen 80
    Include conf.modules.d/*.conf
    User apache
    Group apache
    ServerName xyz.com:80
    <VirtualHost *:80>
        ServerName [url]www.xyz.com[/url]
        DocumentRoot "/var/www/html"
    </VirtualHost>

    config3:

    ServerRoot "/etc/httpd"
    Listen 80
    Include conf.modules.d/*.conf
    User apache
    Group apache
    ServerName localhost:80
    <VirtualHost *:80>
        ServerName [url]www.xyz.com[/url]
        DocumentRoot "/var/www/html"
    </VirtualHost>

    config4:

    ServerRoot "/etc/httpd"
    Listen 80
    Include conf.modules.d/*.conf
    User apache
    Group apache
    ServerName 127.0.0.1:80
    <VirtualHost *:80>
        ServerName [url]www.xyz.com[/url]
        DocumentRoot "/var/www/html"
    </VirtualHost>

Which config file is fit for my example?
