[mysqld]
#不区分大小写lower_case_table_names=1
lower_case_table_names=1
pid-file    = /var/run/mysqld/mysqld.pid
socket        = /var/run/mysqld/mysqld.sock
datadir        = /var/lib/mysql
#log-error    = /var/log/mysql/error.log
# By default we only accept connections from localhost
#bind-address    = 127.0.0.1
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

docker cp  mysqld.cnf mysql:/etc/mysql/mysql.conf.d/mysqld.cnf
