how to maintain host with different server for a specific subdomain without disturbing main domain ?

-
In this tutorial i will expalined how to build subdomain and how to maintain hosting with differnt server for that specific subdomain without disturbing main domain
  • consider X is a domain name example for www.tutorialdba.com/discuss.tutorialdba.com is domain/subdomain.
  • consider Y is a hosting company
step 1.create sub domain  in X(domain name provider) usig A records example for "discuss.tutorialdba.com"

'A' record should be
Name:discuss.tutorialdba.com
Destination IPV4 Address *: 98.202.183.209  #your hosting IP
TTL :is default is better
Note:since your server has apache running it can have unlimited domains/subdomain on a single IP.once you changed 'A' record it will take 4 hours to reflect globally or then you likely still need to wait for DNS propagation. The propagation cycle can take up to 24 hours to complete.

Step 2.you will need to add the following nameservers to /etc/ips.remotedns as root user
this is your domain name provider nameserver & IP,some time name server will not reflect at the time you have to give your (X name server ip)

This entry would be in Y server means your hosting server
dns1.hostgator.in
dns2.hostgator.in
dns3.hostgator.in
dns4.hostgator.in

    (OR)
162.251.82.252
162.251.82.119
162.251.82.123
162.251.82.248
3.Then go to your hosting Cpanel(Y server)
Go to new domain on cpanel
New Domain Name :discuss.tutorialdba.com
Subdomain       :discuss
Document Root   :efault path if you want change path give as per your convenient
then click "Add Domain" your subdomain(X) will be attached to this remote hosting(Y).

Method 1 You can check the mode of the server using "pg_controldata". [pgsql@test~]$ pg_controldata /usr/local/pgsql/data84/ Database cluster state: in archive recovery --> This is Standby Database Database cluster state: in production --> This is Production Database [Master] Method 2 You can use pg_is_in_recovery() which returns True if recovery is still in progress(so the server is running in standby mode or slave) postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- t (1 row) If Return    false   so the server is running in primary mode or master postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- f (1 row)
