[opencms-dev] MariaDB optimization error RHEL

[Yamit David Moreno Socha]

Hello

I am running mysqltunner on my DB server and show memory error

Variables to adjust:
  *** MySQL's maximum memory usage is dangerously high ***
  *** Add RAM before increasing MySQL buffer variables ***
    SET innodb_stats_on_metadata = OFF
    query_cache_size (=0)
    query_cache_type (=0)
    innodb_log_file_size should be (=16M) if possible, so InnoDB total log
files size equals to 25% of buffer pool size.

*The DB is on RHEL 7, memory 64G and 16 cores*

my.cnf:

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

#skip-locking

max_connections         = 100
innodb_file_per_table   = ON
key_buffeir_size        = 1024M
max_allowed_packet      = 2024M
table_cache             = 512
sort_buffer_size        = 32M
read_buffer_size        = 32M
read_rnd_buffer_size    = 32M
myisam_sort_buffer_size = 2048M
thread_cache_size       = 64
query_cache_type        = 1
query_cache_size        = 2048M
expire_logs_days        = 1

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

Can anybody help me please


Thanks
