Mysql ErrorNo 22 on Site installation


#1

Hello,

I’m getting the below error when trying to install a new site using command “bench --site site1.local install-app erpnext”. This is a new installation on Windows Linux SubSustem running Ubuntu.

I’m able to login into mysql through command line using user root and the password which I had set during installation.

Kindly help me with this error.

pymysql.err.OperationalError: (2003, “Can’t connect to MySQL server on u’localhost’ ([Errno 22] Invalid argument)”)

Hi, seems like there is some issue with mysql or mariaDB. Is mariaDB properly installed?
Try typing bench mariadb in terminal inside frappe-bench and check if mariaDB connects.
if not then restart your mariadb service and try

normally u is the prefix to the username, not the DB host machine as you have it here

I tried to delete frappe-bench directory and re-install frappe-bench using below command.

bench init frappe-bench && cd frappe-bench

I get the below error, but the process gets completed successfully.

ERROR: requests 2.21.0 has requirement urllib3<1.25,>=1.21.1, but you'll have urllib3 1.25.1 which is incompatible.
ERROR: botocore 1.12.137 has requirement urllib3<1.25,>=1.20; python_version == "2.7", but you'll have urllib3 1.25.1 which is incompatible.

Below warning is displayed on all bench commands.

  RequestsDependencyWarning)

And on " bench get-app erpnext https://github.com/frappe/erpnext" I get error as below.

  ERROR: Could not find a version that satisfies the requirement unidecode (from erpnext==11.1.20) (from versions: none)
ERROR: No matching distribution found for unidecode (from erpnext==11.1.20)

I think I have some version mismatch error. Should I downgrade version of “urllib3” ?

@trentmu Update urllib3 to urllib3==1.25 in ~/frappe-bench/apps/frappe/requirements.txt

get error as “ERROR: requests 2.21.0 has requirement urllib3<1.25,>=1.21.1, but you'll have urllib3 1.25.2 which is incompatible.

Also get below on all bench commands.

In your case, you probably need to …
Modify the requirements.txt from
urllib3<1.25,>=1.21.1 (1st case) and urllib3<1.25,>=1.20
to
urllib3==1.25.2


#8

I tried using 1.25.2 and got the same error.

To satisfy conditions of requests and botocore, update to 1.24.2. Had to execute “sudo pip install -q -e ./apps/frappe”.

Once that was done, “get-app erpnext” was also completed successfully.

I again get mysql error when trying to install erpnext app to site1.local.

I’m running out of options.

bench mariadb works fine.


#9

This part is still wrong - I’m afraid I don’t know why, or how to fix that particular problem - in particular, if you’re using WLS. There are a couple of people that have gotten it to work (I think), but I don’t know WLS or ubuntu (I prefer manual debian installs).
Hopefully one of those guys who succeeded will see and respond to this post


#10

I faced this issue. When you see this error, just restart Windows and do again, it will work.

@trentmu Thanks for your help!

@lapphan Once I restarted my pc the error magically went away :open_mouth:

#12

Missing tables implies an out of sync system vs. DB schema. A bench migrate should fix it, followed by a bench update. In all it seems that the DB error prevented the install from completing properly


#13

@trentmu It looks like the bench manager was pointing to an older DB which did not have tables. Fixed it to point to the latest DB and it started working.

I’m now able to setup and run the system :slight_smile:

All it took was to restart windows to fix the "Can't connect to MySQL server on u'localhost' ([Errno 22] Invalid argument)") issue.

Thanks for your help.
