Let perform the service command below to see if it is ok. # nicely by pg_ctl in ExecStart, so keep its timeout smaller than this value.Ĭreate a log file in order to start up the PostgreSQL service. # Ideally, the timeout for starting PostgreSQL server should be handled more # Give a reasonable amount of time for the server to start up/shut down. # PGSTARTTIMEOUT should be less than TimeoutSec value.ĮxecStart=/app/postgres/product/14/db_1/bin/pg_ctl start -w -D "/data01" -l "/data01/log/startup.log"ĮxecStop=/app/postgres/product/14/db_1/bin/pg_ctl stop -m fast -w -D "/data01"ĮxecReload=/app/postgres/product/14/db_1/bin/pg_ctl reload -D "/data01" # Maximum number of seconds pg_ctl will wait for postgres to start. # Add a service section and set the max number of open files You need to perform this with root permission access. The reason you need to configure the PostgreSQL service is to easily start, stop, or restart the PostgreSQL service at anytime you want without entering the directory of the PostgreSQL program file or shell script. STEP 6: Configuration of PostgreSQL Service $PGHOME and $PGDATA are the parameters you have been defined in postgres user profile. It is where your data is really stored by using command $PGHOME/bin/initdb -D $PGDATA After finishing you may now initialize the PostgreSQL data cluster in the data directory. It might take several minutes for each make command to execute. #now let's start installing PostgreSQL 14 #install make command if it's not yet install on your server configure -prefix=/app/postgres/product/14/db_1/ #checking possible issue by installing this PostgreSQL 14 #Make sure the ownership and permission of downloaded file is belong to user postgres #login as postgres user and navigate to directory where you download the source code of PostgreSQL 14 and change permission if necessary Now it's time to install PostgreSQL 14 from the source code we just download from step 1 by extracting using the tar command and using the make command to install as you can see below (Please read comment carefully) # The script sets environment variables helpful for PostgreSQLĮxport PGHOME=/app/postgres/product/14/db_1Įxport MANPATH=$MANPATH:$PGHOME/share/man You can do this by following the below instruction If you do not wish to change that is also fine. The preparation of user postgres profile is to easily access PostgreSQL instance after done installation such as entering to the path of program directory or data directory. STEP 4: User "postgres" Profile Preparation Sudo chown -R postgres:dba /app/postgres/product/14/db_1/ Sudo mkdir -p /app/postgres/product/14/db_1/ #Create directory for postgresql software to be installed on Sudo chown -R postgres:dba /home/postgres/ Next, we have to create a home directory of the user postgresas the following command #Create home directory of user postgres #Giving password to user "postgres" (Let use Pgs123456 as password) Let's assume we want to create a group named dba and user postgres to have permission to access data in the PostgreSQL database. Furthermore, we are going to prepare a data directory as well as archive and backup in case you back up your data into the same server before transferring it to the backup disk. This is a very important security measurement since you want only the created user to have the ability to access your data in the database. In this step, you are going to prepare your server before you start the installation of PostgreSQL 14 such as group and user that you want to specifically assign permission to work only with Postgresql. Therefore, we have to install those packages first as the following command sudo apt-get update There are some dependent packages such as gcc, zlib1g as a prerequisite to installing PostgreSQL. You can download using the wget command as following wget STEP 1: Download Source from PostgreSQL websiteįirst, you have to download the source code of new released PostgreSQL 14 from the official website here. In this experiment, we are going to use Google Cloud Engine (Similar to AWS EC2 or Digital Ocean Droplet) to perform it. Now, let's start to fresh source installation of PostgreSQL 14 on ubuntu 20.04. If you are using PostgreSQL with cloud providers such as Amazon Web Services or Digital Oceans you may have to wait for their update or you can check with their support in order to get at least the planned upgrade date. This release was highly recommended to upgrade especially for large, high-connection-count sites such as bank or telecom sector. In this release, there are no huge gigantic features but there are many small things that will make your task better and easier. PostgreSQL 14 has been officially released on 30 September 2021 with hundreds of improvements, fixes, and changes that have been mentioned in the release note on their official website.
