Hey everyone !

Hey @pchatzilabrou

What does OpenSearch logs show?
Do you see errors there and if so what does it show?

Hey ,

I decided to start my installation all over again and i saw that during installation step 3. Choose the version of OpenSearch you want to install. Unless otherwise indicated, the latest available version of OpenSearch is installed.

Iam typing this

sudo OPENSEARCH_INITIAL_ADMIN_PASSWORD=$(tr -dc A-Z-a-z-0-9_@#%^-_=+ < /dev/urandom | head -c${1:-32}) yum install ‘opensearch-2.15.0’

but iam getting this error.

-bash: /dev/urandom : No such file or directory

but the installation process normaly and i didnt see it the first time. How am i suppose to syntax the OPENSEARCH_INITIAL_ADMIN_PASSWORD ;

ah thats the new way.

Create your password then place it into your file called

/etc/environment.

Example:

root@opensearch:/usr/share/opensearch/plugins/opensearch-security/tools# cat /etc/environment.
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"
OPENSEARCH_INITIAL_ADMIN_PASSWORD=PasswordHoward123!

Logged out and back in.
