重点，复制之前的my.cnf 要能用，touch一个是不行的；
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
docker run -p 3306:3306 --name mysql -v /docker/mysql/conf/:/etc/mysql/conf.d -v /docker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=admin123 --privileged=true --restart=always -d mysql:5.7 --lower_case_table_names=1
4、直接连客户端
加一个时区的启动语句：
docker run -p 3306:3306 --name mysql -v /docker/mysql/conf/:/etc/mysql/conf.d -v /docker/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=admin123 --privileged=true --restart=always -d mysql:5.7 --lower_case_table_names=1 --default-time_zone='+8:00'
遇到这种问题，重启：
/usr/bin/docker-current: Error response from daemon: driver failed programming external connectivity on endpoint mysql (3230526a5128e57ec56cc4d1a48ade80c175bc5d9c8e9cc1456ebce50012f4ab): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 3306 -j DNAT --to-destination 172.17.0.2:3306 ! -i docker0: iptables: No chain/target/match by that name.
解决方法
docker服务启动时定义的自定义链DOCKER被清除
重启即可 systemctl restart docker
======================================
加一个严格要求大小写的，也就是大小写敏感的my.conf：
[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 # !includedir /etc/mysql/conf.d/ !includedir /etc/mysql/mysql.conf.d/
这个my.cnf 不一定管用；
