biubiu使用DockerCompose启动容器
1.Docker Compose 启动 MySQL
编写docker-compose.yml
yaml
version: '3.8'
services:
mysql:
container_name: mysql
image: mysql
restart: always
ports:
- "3306:3306"
volumes:
- ./mysql/conf:/etc/mysql/conf.d
- ./mysql/logs:/logs
- ./mysql/data:/var/lib/mysql
- ./mysql/db:/docker-entrypoint-initdb.d/
environment:
- "MYSQL_ROOT_PASSWORD=root"
- "TZ=Asia/Shanghai"
command:
--default-time-zone='+8:00'
--default-authentication-plugin=mysql_native_password
--innodb-buffer-pool-size=64M
--character-set-server=utf8mb4
--collation-server=utf8mb4_general_ci
--max_connections=1000
--innodb_lock_wait_timeout=500一些初始化配置
mysql容器脚本初始化
有时候，我们在容器启动时需要初始化一下sql脚本，如下
- 有需要初始化的sql脚本，可以放到
./mysql/db下，容器启动会自动执行 - 连接MySQL:
ip(127.0.0.1):3306 root/root
