I am not very familiar with Linux I might stumble at basics.
Very interested in OpenSource ERP system; I decided to give it a shot and I am determined to make this work.
I downloaded the production image from erpnext.org fwdslash download and booted it on VirtualBox.
Everything looked great and I liked ERPNext. I had to shutdown and restart my system “Internal Server Error” shows up.
After searching around a bit, following running commands:
sudo mysqld --tc-heuristic-recover=ROLLBACK
sudo service mysql start
…everything was good again. A sudden power failure few hours later pushed me back to “Internal Server Error”. Trying the above rollback statements did not work.
Here’s what I did to resolve my situation. I am still not sure how and what impact the following did on ERPNext server. Someone explaining me what happened will help in better understanding what happened:
Start the VBox server
In terminal run command: sudo vi /etc/mysql/my.cnf <<opens my.cnf a mariadb config file in vi editor
scrolled to the section where statement starts with “innodb_…”
Pressed “i” to enter insert mode
Added new line: innodb_log_checksums = ON
Press “Esc” key
Type “:wq” <<this saves and quits the vi editor
In terminal run command: rm /var/lib/mysql/ib_logfile*
In terminal run command: sudo reboot
Voila!
localhost:8080 is accessible again!
Today I learned:
linux is cool
vi is text editor
command line is not that scary
DO NOT PANIC if something goes wrong. Make a copy of disk and be brave
I am sorry if this is too basic to be here on ERPNext forum. But I figured someone else might stumble upon same issue some day.
