  • Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.

  • Run the following commands to create these functions:

     mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
     mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"

OS: Ubuntu 14.10 64-bit I do not have MySQL installed.

Percona is installed but does not start. Both /var/log/mysql.err and /var/log/mysql.log are blank.

root@technich:~# /etc/init.d/mysql stop

  • Stopping MySQL (Percona Server) mysqld [ OK ] root@technich:~# /etc/init.d/mysql start
  • Starting MySQL (Percona Server) database server mysqld [fail]

User mysql exists and has the correct entry in /etc/passwd

root@technich:~# ps -ef |grep mysql root 40369 26832 0 07:14 pts/0 00:00:00 grep --color=auto mysql

How do we solve this?

New EC2 EE install fails with Unable to install nginx-custom, exit status = 100


EasyEngine is not yet suppport for Ubuntu 14.10 yet. The main reason behind this is Percona package is broken in Ubuntu 14.10,

Ref: https://bugs.launchpad.net/percona-server/+bug/1391103

Percona yet not fixed this issue. As soon as they fix this issue, we will release EasyEngine for Ubuntu 14.10
