Docker安装mysql,并配置忽略大小写

docker run --name mysql8 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -d --network my-net -v /c/Users/WilsonCai/WilsonPrivate/docker-mysql/:/var/lib/mysql mysql --lower_case_table_names=1

• -e MYSQL_ROOT_PASSWORD :设置mysql密码
• -v /c/Users/WilsonCai/WilsonPrivate/docker-mysql/:/var/lib/mysql:挂载磁盘实现数据持久化,docker-mysql文件夹如果已有文件需要被清空,Linux系统使用/home/mysql
• --lower_case_table_names=1 :忽略大小写，docker mysql默认区分大小写的
• --network 设置mysql在Docker中的网络设置

注:参数顺序一定要对，--lower_case_table_names=1要加在镜像名后面，镜像名前面是参数，后面是mysql配置，不然会报错,而且只能初始化时配置

注:docker内其他容器或者本机可以通过host.docker.internal:3306访问docker中的mysql

mysql修改权限密码方式

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

flush privileges;

Docker 安装kafka

kafka是docker-compose的组合并需要持久化

version: "3"

docker-compose up -d 此命令可以将上述组合上线

Docker 安装redis

docker run -v /c/Users/WilsonCai/WilsonPrivate/docker-redis:/usr/local/etc/redis --name myredis -p 6379:6379 -d --network my-net redis

Docker 安装kowl

docker run --name mykowl -p 8888:8080 -e KAFKA_BROKERS=host.docker.internal:9092 -d quay.io/cloudhut/kowl:master

注:前提是本机安装了kafka,可以通过host.docker.internal进行访问

Docker常用命令

1. build时可以直接tag到远程目录省去tag这一步

   docker build -t my-app:1.0 .

2. 打tag到指定目录,wilsoncai666是dockerhub中的一个repository,其余地址私人仓库按实际情况填写

   docker tag my-app:1.0 wilsoncai666/my-app:1.0

3. push到dockerhub中的个人仓库中,push刚刚tag之后的名称,同理可以推送到任意指定repository,其余非官方仓库需要进行登录才可以进行pull

   docker push wilsoncai666/my-app:1.0

4. 删除容器,如果容器正在运行,删除之前记得进行stop

   docker rm <container-name/id>

5. 删除镜像文件

   docker rmi <image-name/id>

6. 查看日志

   docker logs <container-id>

7. 进入容器内部,就可以看到我们构建的的镜像是不是按照Dockerfile规定把文件复制到相应的目录

   docker exec -it <container-id> /bin/sh(或者是bash)

8. 组合上线或下线

   docker-compose -f xxx.yaml up

   docker-compose -f xxx.yaml down
