VMWARE Player 6.0.3 running on Centos 6 "Could not open /dev/vmmon: No such file or directory. Please make sure that the kernel module `vmmon' is loaded."

Before this I'm using the older version of vmplayer on Centos 6. Everything work fine. Last week I upgraded the vmware player to 6.0.3 and I got problem to load the guest OS. The VMware player complain that "Could not open /dev/vmmon: No such file or directory. Please make sure that the kernel module `vmmon' is loaded."

After a long time searching for a solution, finally I found it. Just follow the simple stpes below:

1. Open your terminal
2. Type sudo mv /usr/lib/vmware/modules/binary /usr/lib/vmware/modules/binary.old
3. Then type sudo vmware-modconfig --console --install-all --appname="VMware Player" --icon="vmware-player"

Now I can start guest OS without any problem. Hope it helps!

MySQL - Error code 1140

Error Code: 1140. In aggregated query without GROUP BY, expression #1 of SELECT list contains nonaggregated column 'dbname.a.column_name'; this is incompatible with sql_mode=only_full_group_by

In order to resolve this issue, we have to turn off ONLY_FULL_GROUP_BY sql_mode.

1. Check sql_mode by issue this command:
   SELECT @@sql_mode;
2. You'll see the output like below:
   ONLY_FULL_GROUP_BY
3. Now turn off the ONLY_FULL_GROUP_BY by issuing this command:
   SET sql_mode = '';

Done!
