docker 安装mysql5.7 加my.cnf

1、先新建文件夹： mkdir -p /docker/mysql/{logs,conf,data}
2、获取镜像:docker pull mysql:5.7
3、启动：
docker run -p 3306:3306 --privileged=true -v /docker/mysql/logs:/logs  -v /docker/mysql/data:/var/lib/mysql  -v /docker/mysql/conf/my.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf -e MYSQL_ROOT_PASSWORD=admin123 -d mysql:5.7

4、直接连客户端

[mysql]
#设置mysql客户端默认字符集
default-character-set=utf8
socket=/var/lib/mysql/mysql.sock

[mysqld]
#修改大小写敏感
skip-grant-tables
lower_case_table_names=1
#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 
#设置时区
default-time_zone=‘+8:00‘
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
