ERPNext Installation Issues

Hi,
I am trying to install ERPNext on ubuntu 16.04 version and its failing with the following error.

oslabs@oslabs:~/test-frappe-bench$ bench new-site foo.bar
MySQL root password: 
================================================================================
Creation of your site - foo.bar failed because MariaDB is not properly 
configured to use the Barracuda storage engine. 
Please add the settings below to MariaDB's my.cnf, restart MariaDB then 
run `bench new-site foo.bar` again.


[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci

[mysql]
default-character-set = utf8mb4

================================================================================

I followed the below link
Home Ā· frappe/frappe Wiki Ā· GitHub step by step. Also, i rechecked all the settings in /etc/mysql/my.cnf and these settings are present as part of this. I restarted mysql,mariadb services. As a last resort, i restarted the system and bench as well but was of no use. Any help on this would be highly appreciated.

Thanks,
-Surya

Just to be sure, i checked the the path of the configuration file as well.
:~$ find /etc -name my.cnf
/etc/mysql/my.cnf .

BTW i have gone through similar posts which has a mention of this problem and tried out the suggestions.Any insights on the root cause of the issue ?

Update - I could solve the issue maria db issue with changes in the config file and could proceed further. But after making all the changes and configuring the erp next, when i start the bench it exits with the following error.

bench-start
bench-start: command not found
~/test-frappe-bench$ bench start

~/test-frappe-bench$

I changed the limits.conf and sysctl.conf to accommodate maximum open files. Though I could get rid of the warnings its landing a connection refused issue. I checked the port bindings to ensure that no duplicate process are running.

>> 17:19:41 worker_default.1 | redis.exceptions.ConnectionError: Error 111 connecting to localhost:11000. Connection refused.

Any help on this issue will be highly appreciatedā€¦

Thanks,
-Surya

i would start here
i had a similar issue on on opensuse leap 15
the rule of thumb is to first get rid off all errors before continuing

Check if your Redis server instance is running as following, if not then you need to install/reinstall it first (sudo apt-get install --reinstall redis-server)

service redis-server start
service redis-server status

do remove following file then do as above, then check if bench starts

cp /var/lib/redis/redis.rdb /var/lib/redis/redis.rdb.backup
rm /var/lib/redis/redis.rdb

it may be due to malformed my.cnf
Recreating all parameters a fresh, might help to fix this issue.

@clarkej recommendsā€¦

These may offer clues too?

sudo service mysql status
sudo less /var/lib/mysql/mysql-error.log

I made all the required changes to see off all the warning messages but couldnā€™t start the bench.

-rw-r--r-- 1 redis redis 18 Jul 30 16:27 dump.rdb
-rwxr-xr-x 1 root  root  18 Jul 30 16:00 dump.rdb.backup

Redis server is running fine on the system and i ensured to delete the older dump.rdb in the redis folder. After all these changes, i restarted the system and started the bench but it failedā€¦

Best way out, is take backup of MySQL DB and sites directory.
Format the server and reinstall bench from scratch but, This time use auto installer with flag to provision developer environment.

Example:

python install.py --develop --user frappe

On the very first time, was that my.cnf empty or having some text ?
