3. PostgreSQL

 

Database Hardware Requirements :

Minimum Hardware requirement for PostgreSQL 9.5
HDD		100 GB

CPU		4 vCPUs
OS		CentOS

I am using PostgreSQL with CentOS as per my requirement ,use this link for complete HW check ( https://pubs.vmware.com/vcd-80/topic/com.vmware.vcloud.install.doc_80/GUID-C258BED7-9664-4DFE-B812-100281D4D460.html )

Install CentOS 7 :

1. 1. Step 1: Download The ISO Image.
   2. Step 2: Make A bootable Drive.
   3. Step 3: Begin Installation.
   4. Step 4: Select Language And Keyboard.
   5. Step 5: Change The Installation Destination.
   6. Step 6: Select The Partitioning Scheme.
   7. Step 7: Create A Swap Space.
   8. Step 8: Create A Mount Point.
   9. Set the root password and reboot .
   10. Create user .

At last you  will get the desktop ..

 

You need to update the OS and install required components :

Connect VM with SSH  and use below command :

1.     yum update yum
2.      yum update
3.     Reboot the  OS

Next will Install the PostgreSQL 9.5 rpm and core packages .

1. rpm -ivh http://yum.postgresql.org/9.5/redhat/rhel-7-x86_64/pgdg-centos95-9.5-2.noarch.rpm
2. yum install net-tools postgresql95 postgresql95-server postgresql95-libs postgresql95-contrib

 

Now you will nedd to change SQL password and set SQL start on boot.

1. passwd postgres
2. /usr/pgsql-9.5/bin/postgresql95-setup initdb
3. systemctl start postgresql-9.5.service
4. systemctl enable postgresql-9.5.service

Now Change the postgres user .

1.   sudo -u postgres -i

Create the vCD user and database

Next need to create the vCD user account and DB .

1. psql
2. create user vcloud;
3. alter user vcloud password ‘VMware1!’;
4. alter role vcloud with login;
5. create database vcloud;
6. grant all privileges on database vcloud to vcloud;

Now Allow PostgreSQL connections with default firewall configuration

1. Log with root and use below step.
2. firewall-cmd –zone=public –add-service=postgresql

Next need to allow the vcloud user  login externally .

Add below line …

1. vi /var/lib/pgsql/9.5/data/pg_hba.conf
   • host    all             all             10.0.0.0/24            md5

Now set the postgreSQL listening port and ip then sync NTP clock

1. vi /var/lib/pgsql/9.5/data/postgres.conf
2. Then add below input :
   • listen_address = ‘*’
   • port= 5432
3.  yum install ntp

 

Now need to configure the NTP server to synchronize the clock with vCD and DB .

1. vi /etc/ntp.conf

Start and validate the ntpd service is running .

1. systemctl start ntpd
2. systemctl enable ntpd
3. systemctl status ntpd

Now need to validate ntpd is sync with currect NTP server and also check date .

1. ntpq -p
2. date -R

It’s time to reboot the server .

 

Thanks hope you like it.
