Thanks for the response

Reinstalled mysql from instruction from the mariadb home page…the current problem is as follows

raise Exception(“Database %s already exists” % (db_name,))
Exception: Database _1bd3e0294da19198 already exists

On the server side the following happens

2019-06-04 13:24:36 10 [Warning] Aborted connection 10 to db: ‘unconnected’ user: ‘root’ host: ‘localhost’ (Got an error reading communication packets)

Delete the existing database, or specify a different db name on bench new-site:

% bench new-site --help

I am following the instructions at this link…

Would this is complete to bring up the erpnext system

In my understanding, you stuck in first site creation and in some way you already tried before and the “old” db still there.
So, in this case, you already have the same db name that bench new-site is going to create, if you don’t delete the old db or you don’t specify a new name, you can’t proceed.

Hope this can help you

I tried this command:
Now I am getting this error:

For key innodb_large_prefix. Expected value ON, found value OFF
For key collation_server. Expected value utf8mb4_unicode_ci, found value utf8mb4_general_ci
For key innodb_file_format. Expected value Barracuda, found value Antelope
================================================================================
Creation of your site - erp.LTS failed because MariaDB is not properly
configured.  If using version 10.2.x or earlier, make sure you use the
the Barracuda storage engine.

Please verify the settings above in MariaDB's my.cnf.  Restart MariaDB.  And
then run `bench new-site erp.LTS` again.


================================================================================
Database settings do not match expected values; stopping database setup.

could you please help me

Edit your mysql config file…
nano /etc/mysql/my.cnf
and make sure it includes something like this…

[mysqld]
innodb-file-format=barracuda
innodb-file-per-table=1
innodb-large-prefix=1
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
# Set buffer pool size to 50-80% of your computer's memory
innodb_buffer_pool_size=1024M
# Set the log file size to about 25% of the buffer pool size
innodb_log_file_size=256M
innodb_log_buffer_size=128M
# the default here is 4MB, or maybe 16MB?? in more recent versions, which sometimes allows for disconnects in the middle of transactions
max_allowed_packet=64M

[mysql]
default-character-set = utf8mb4

Then restart mysql
sudo systemctl restart mysql
and then try to run the bench new-site erp.LTS again
