Start/Stop/Restart processes from the UNIX command line:
sudo supervisorctl start processname
sudo supervisorctl stop processname

Postgres Configuration on RedHat

This will install Postgresql on a RedHat 6.4 or CentOS 6.4 system and will allow password-protected remote login access. 

# Open the firewall to allow remote postgres connections
sudo /sbin/iptables -A INPUT -p tcp --dport 5432 -j ACCEPT

sudo /sbin/service iptables save
sudo /sbin/service iptables restart

# Install packages through yum
sudo yum install vim-enhanced
sudo yum install postgresql-server

# Initialize a new database directory
sudo service postgresql initdb 

# Start the database server
sudo service postgresql start 

# Add postgres to the default runlevel 
sudo chkconfig postgresql on
sudo chkconfig postgresql --list
sudo chmod 755 /home/idcuser/

# Edit the postgres.conf to allow connections from all ips

sudo vim /var/lib/pgsql/data/postgres.conf
listen_addresses="*"

# Edit the pg_hba.conf file to allow password auth for any ip

sudo vim /var/lib/pgsql/data/pg_hba.conf
host all all 0.0.0.0/0 md5

# Restart postgres
sudo /etc/init.d/postgres restart

# Configure a postgresql superuser and new schema.
