I have to install a specific version of Postgresql to my AWS-EC2 instance. I followed the tutorial :Setting up PostgreSQ.
In the past i did as per the tutorial and it worked perfectly fine. This time, since I need the 9.6 version, I twisted a bit :
$ sudo yum install postgresql96 postgresql96-server postgresql96-devel postgresql96-contrib postgresql96-docs
the installation worked fine. I am now trying to resume the setup :
sudo postgresql-setup initdb
and get the following error:
$ sudo postgresql-setup initdb
sudo: postgresql-setup: command not found
i tried the following as well just for the sake of it.
$ sudo postgresql96-setup initdb
sudo: postgresql96-setup: command not found
$ ls -ila /etc/rc.d/init.d
total 264

Chances are high that Amazon Linux doesn't fit well with PostgreSQL 9.6 or need extra undocumented custom installation steps.
To install a specific version of services like PostgreSQL, the easiest way and probably the new standard is using Docker (and docker-compose).
So, (almost) whatever the Linux distribution you are using:
sudo yum install docker then sudo service docker start (The extensive doc for Amazon Linux or other Linux distributions)
Then install docker-compose
Find an example of a docker-compose.yml file for PostgreSQL, there are many. Just make sure your image parameter is set to image: "postgres:9.6"
docker-compose up and you should be all setこの記事はインターネットから収集されたものであり、転載の際にはソースを示してください。
