I have a 2gb ram memory, and somehow mysqld.bin is utilizing 20%+ memory when nobody is accessing the server. I just installed everything fresh. not sure why it is taking so much memory. I am utilizing InnoDb MySQL 5.6.23.
When the database grows, does the mysqld.bin memory usage grow?

I tried tuning-primer.sh (./tuning-primer.sh > result.txt) , but i have a couple of errors:
Code:
tput: Unknown terminal "linux"
tput: Unknown terminal "linux"
tput: Unknown terminal "linux"
tput: Unknown terminal "linux"
tput: Unknown terminal "linux"
tput: Unknown terminal "linux"
would you like to provide a diff. socket? : n
do you have your login handy? y
user: xxxx
password: xxxxxxxx
tput: Unknown terminal "linux"
woudl you like me to crate a ~/.mycnf file for you? n
tput: Unknown terminal "linux"
tput: Unknown terminal "linux"

I downloaded sqltuner, and ran it by: sudo perl mysqltuner.pl > result.txt.
How does the recommendation below helps me to lower the memory usage?

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Remove Anonymous User account - there is 2 Anonymous account.
    Set up a Password for user with the following SQL statement ( SET PASSWORD FOR 'user'@'SpecificDNSorIp' = PASSWORD('secure_password'); )
    Set up a Secure Password for [email protected] ( SET PASSWORD FOR 'user'@'SpecificDNSorIp' = PASSWORD('secure_password'); )
    MySQL started within last 24 hours - recommendations may be inaccurate
Variables to adjust:
    query_cache_type (=1)
    innodb_buffer_pool_instances (=1)
