all simple you had screwed your SQL DB.
Usually it is happening when you had powered off PC while VM ware and eve VM was running...
There is solution but please visit EVE Live chat...
http://www.eve-ng.net/live-helpdesk

Use google account or create new for join

Hi,

I have Google account/username same as the login name to this forum but I can not login to live-help desk. I can login to Google mail but not to your live-help desk. The login error says "User not found or incorrect password".

Can I please know the process to get access to live-help desk?

Mathew

Live Helpdesk is not the same account as it is here.
Use your google email logon for chatnot this account.

Or you can create new chat account..

UD

Hi UD,

I tried multiple times and multiple PCs but I can not login to helpdesk. My Google ID works if I directly login to Gmail but not through LiveHelpdesk.
This happens after I normal server shutdown - graceful shutdown and powered up gain - unable to logon to EVE.

is there way to that you can let me know the steps to recover the SQL server to login?

Please help me.

See the errors;

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.

key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 76387 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

not only google account can be used for chat.
Any other email as well.
Let me know your username in the chat I will check it, activate.
Do not mess chat with this forum logins, they are diff.
Uldis

here you are. It is dangerous commands and can end for you with EVE re install.

#######stop sql processess###########
systemctl stop mysql

#########remove lock for libs##############
rm -f /var/lib/dpkg/lock

##############hard erase of sql and related packages################
export TERM=xterm
apt-get --purge autoremove $(dpkg -l | grep 'mysql' | awk '{print $2}')

When prompted, confirm with yes

rm -rf /var/lib/mysql

rm -rf /etc/mysql


##########Install eve-ng again##############

apt-get install eve-ng

Hi UD,

Thank you for your reply and the steps.

Your steps are followed exactly and I could get it to work now. I can login and run all my LABs successfully.
I also backup up the below 3 folders, in case, it runs into a crash and to re-build the server.

/opt/unetlab/addons/
/opt/unetlab/labs/
/opt/unetlab/tmp/

Mathew
