I've been trying to install percona server on a fresh Google compute engine instance.

I haven't installed mysql server previously. I followed the instructions from here.

I get this when I use:

apt-get install percona-server-server-5.6 percona-server-client-5.6

Setting up percona-server-common-5.6 (5.6.15-rel63.0-519.wheezy) ...

 * 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'"
    mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"

 * See http://www.percona.com/doc/percona-server/5.5/management/udf_percona_toolkit.html for more details

[FAIL] Starting MySQL (Percona Server) database server: mysqld . . . . . . . . . . . . . . failed!

What am I doing wrong?

When I type /etc/init.d/mysql start I get

[....] Starting MySQL (Percona Server) database server: mysqld/etc/init.d/mysql: fork: Cannot allocate memory

I was having the exact same problem on an AWS t1.micro that has about .6GB of memory. It would go through the entire setup process then fail on initializing mysqld. As it turns out, that instance did not have enough memory to get percona server 5.6 going. I brought up a faster instance running 3.75GB of memory and it started without issue.

If I were to speculate, I would guess you are on the f1-micro instance which is why you are getting the "Cannot allocate memory" errors. Try the g1-small instance and see if that is enough to get mysql running.

I was/am using Percona's default configuration and I was able to successfully install on a Digital Ocean droplet with 1GB of memory. So, it seems as though the magic number of needed memory is between .6GB and 1GB.

  • Agree with your diagnosis. Only comment I have is that it is possible to change defaults to use less memory: tocker.ca/2014/03/10/… - but upgrading the instance is a better solution. May 14, 2014 at 20:08
  • Thanks. Yes i got a similar answer on StackOverflow. I got a bigger instance and it worked. Percona server seems to hog atleast 400mb+ memory and that could be the reason it did not work on the smaller instance. stackoverflow.com/questions/21274573/… May 15, 2014 at 2:18
