how to preview a domain not pointed yet to sentora?

[Ron-e]

In Sentora go to "Server Admin" > "Module Admin" > "Apache Config" and copy&paste the code below in "Global Sentora Entry".
Select "Force Update" at the bottom and save.
Run the daemon manually (php -q /etc/sentora/panel/bin/daemon.php) to speed things up.
And it should work, hopefully.

Code:

</virtualhost>

# Add Alias for DNS-Less Previews
<VirtualHost *:80>
    ServerName xxx.xxx.xxx.xxx
    DocumentRoot "/var/sentora/hostdata"
    php_admin_value suhosin.executor.func.blacklist "passthru, show_source, shell_exec, system, pcntl_exec, popen, pclose, proc_open, proc_nice, proc_terminate, proc_get_status, proc_close, leak, apache_child_terminate, posix_kill, posix_mkfifo, posix_setpgid, posix_setsid, posix_setuid, escapeshellcmd, escapeshellarg, exec"
    AliasMatch ^/~([a-zA-Z0-9]+)/?(.*) /var/sentora/hostdata/$1/public_html/$2
    <Directory /var/sentora/hostdata>
        Options FollowSymLinks
        AllowOverride All
        Order Allow,Deny
        Allow from all
        DirectoryIndex index.html index.htm index.php index.asp index.aspx index.jsp index.jspa index.shtml index.shtm
        <IfModule mod_php5.c>
            AddType application/x-httpd-php .php
            php_flag magic_quotes_gpc Off
            php_flag track_vars On
            php_flag register_globals Off
            php_admin_value upload_tmp_dir /var/sentora/temp
        </IfModule>
    </Directory>

Replace xxx.xxx.xxx.xxx with your server ip.
