31.5. SQL Error (1038): Out of sort memory, consider increasing server sort buffer size

解决方法,在 my.cnf 中增加 sort_buffer_size=512k 配置项

		
[root@gitlab ~]# cat /etc/my.cnf.d/mysql-server.cnf

# 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 mysqld according to the
# instructions in http://fedoraproject.org/wiki/Systemd
