基于Alpine的mysql Docker镜像

usage
注意 直接跑docker docker run -it --name mysql 会再次生成mariadb.conf 小心
数据库文件就是当前目录的mysql
cat .env
# Environment variables for docker-compose command
ALPINE_VERSION=3.14
IMAGE_NAME=evan886/mariadb-alpine
# Running
CONTAINER_NAME=mysql
MYSQL_ROOT_PASSWORD=root2240881
MYSQL_USER=evan
MYSQL_PASSWORD=evanlai36
MYSQL_DATABASE=admin
HOST_ADDRESS=3306
cat docker-compose.yml
version: '2'
services:
mysql:
image: ${IMAGE_NAME}:${ALPINE_VERSION}
container_name: ${CONTAINER_NAME}
environment:
- MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
- MYSQL_USER=${MYSQL_USER}
- MYSQL_PASSWORD=${MYSQL_PASSWORD}
- MYSQL_DATABASE=${MYSQL_DATABASE}
volumes:
- .:/app
ports:
- "${HOST_ADDRESS}:3306"
restart: always
# restart 动作在debian11 好像不起效果
docker-compose up -d
mysql -uroot -p -h127.0.0.1
mysql_secure_installation设置初始密码无效
原因
以前的SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');已经被弃用，取而代之的是ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
user mysql;
ALTER USER 'root'@'localhost' IDENTIFIED BY '新密码';
flush privileges;
exit;
mariadb通过mysql_secure_installation设置初始密码无效

trouble shooting
我最终在Dockerfile 添加 COPY mariadb-server.cnf /etc/my.cnf.d/mariadb-server.cnf EXPOSE 3306 van@myxps:~$ mysql -uroot -p -h127.0.0.1 Enter password: ERROR 2013 (HY000): Lost connection to MySQL server at 'handshake: reading initial communication packet', system error: 11 解决办法 注释掉这行 skip-networking 跳过TCP/IP连接 cat /etc/my.cnf.d/mariadb-server.cnf [mysqld] #skip-networking 处理过程 其实一开始telent 3306不通就差不多是网络问题啦 , 因为容器里面是可用的 别人的解决办法 我也记录一下 虽然和我的不同 1、将 /etc/my.cnf 中的bind-address参数修改成0.0.0.0，表示允许任何ip主机访问此数据库 and skip-name-resolve
Lost connection to MySQL server at 'reading initial communication packet', system error: 0
