Dockerfile构建mysql镜像

mkdir mysqld
2,构建my.cnf文件

cd mysqld
vim my.cnf
[client]
port = 3306
socket=/usr/local/mysql/mysql.sock
[mysqld]
user = mysql
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port = 3306
character-set-server=utf8
pid-file = /usr/local/mysql/mysqld.pid
socket=/usr/local/mysql/mysql.sock
bind-address = 0.0.0.0
skip-name-resolve
max_cOnnections=2048
default-storage-engine=INNODB
max_allowed_packet=16M

3，构建Dockerfile文件

vi Dockerfile

EXPOSE 3306
RUN echo -e "#!/bin/sh \nsystemctl enbale mysqld" > /run.sh
RUN chmod 755 /run.sh
RUN sh /run.sh
CMD ["init"]
4,构建镜像

docker build -t mysql:centos .
5,构建容器

docker run -d --name=mysql--server -P --privileged msyql:centos
6,进入容器给权限

docker exec -it 容器id /bin/bash
7,登录mysql

mysql -u root -p #登录MySQL //如果无法无密码登录，可以回宿主机查看/etc/my.cnf 文件，将其清空
​
grant all privileges on *.* to 'root'@'%' identified by '123456';
grant all privileges on *.* to 'root'@'localhost' identified by '123456';
​
flush privileges;
exit
8,在宿主机yum安装msyql

yum -y install mysql
9,客户端连接MySQL容器

• 这时候进入宿主机通过ip地址是可以共享mysql的
