docker 安装mysql5.7 加my.cnf

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；

mysql -u root -p

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'admin123'; 

show variables like '%lower_case_table_names%';

　　试了N久：
