Hi,Thanks again.I have another questions:
1- Should I just install PostgreSQL normally on the Standby server? 
2- Are the steps the same for other Linux distributions like Debian?

Hi,Do I have to run this command on the server where the main database is 
located?

Suppose you want to transfer the database of a website like Amazon.com to a new 
server and delete the old one. Many users are buying and selling on this 
website at the same time and it is not possible to turn off the server. What do 
you do to move a database to another server?

 I used this web page to implement hot standby via physical streaming.  This 
command sets up everything for you:pg_basebackup \
            --pgdata=$PGDATA \
            --dbname=service=basebackup \
            --verbose --progress \
            --checkpoint=fast \
            --write-recovery-conf \
            --wal-method=stream \
            --create-slot --slot=pgstandby1 \
            --compress=server-zstd
I got it from 
https://www.tecmint.com/configure-postgresql-streaming-replication-in-centos-8/,
 which I encourage you to read.
For guarding, and situations with a minimal RTO SLA, I use PgPool-II to manage 
the cluster, automatic failover and Virtual IP address.  Note that only two 
database servers are needed.  Install PgPool on the two DB servers, and a 
third, smaller system.
There are other products which do the same thing as PgPool, and you might find 
them better.
