Try this for login problem its working for me
sudo update-rc.d redis-server disable
sudo service redis-server stop
sudo supervisorctl start all
Thanks. It’s working. [login issue]
Brother, the server I’ve installed is super slow for some unknown reason. I’m gonna try to install again on a fresh server and then try all this. I will get back to you if I face this problem.
Thanks
Finally i finished the installation successfully 
hello guys @Alaa_Badri @Mohamed_khalifa @anebi @benjamin i just solved the problem right now 
but i will apply a pull request to the main bench repo to apply the solution 
i wish if they accept my pull request to solve this serious problem, its under pull request " fix-mysql-error " by elba7r.
Best Regards

i am facing this error in production version
Hello
This fixed this:
Specifically step #4 and #5 if needed!
I am getting below error.
and here is the screenshots of different .cnf files
/etc/mysql/conf.d/mysql.cnf 
/etc/mysql/mariadb.conf.d/50-server.cnf
/etc/mysql/my.cnf
/etc/mysql/mysql.conf.d/mysql.cnf
/etc/mysql/mysql.conf.d/mysqld.cnf
I have read many articles and very confused what to change in which file.
