mkdir /usr/local/docker/mysql/logs
mkdir /usr/local/docker/mysql/data
mkdir /usr/local/docker/mysql/conf
4.创建my.cnf文件，内容如下
[mysql]
#设置mysql客户端默认字符集
default-character-set=utf8
socket=/var/lib/mysql/mysql.sock
[mysqld]
#mysql5.7以后的不兼容问题处理
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# 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
#允许最大连接数
max_connections=200
#服务端使用的字符集默认为8比特编码的latin1字符集
character-set-server=utf8
#创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
lower_case_table_names=1
max_allowed_packet=16M

default-time_zone='+8:00'
[mysqld_safe]

pid-file=/var/run/mariadb/mariadb.pid
#

#
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
