Etherpad won’t start and errors with output
Etherpad Startup execution failed with non-200 response: 500
Cause:
Etherpad can’t talk to MySql
Things to check:
1. Your /etc/hosts
2. Your MySQL conf under networking – /etc/mysql/my.cnf
3. Your MySQL conf bind-address – /etc/mysql/my.cnf
4. The etherpad.SQL_JDBC_URL value in /usr/share/etherpad/etherpad/etc/etherpad.local.properties
Make sure these are correct then restart mysql. Don’t assume that connecting with mysql -uroot -ppassword etherpad is a good test.
