2. docke run

>> docker run -d  --name nginx -p 8080:80 nginx:1.17.9  
//nginx:1.17.9  （同上面pull的Status: Downloaded newer image for nginx:1.17.9
docker.io/library/nginx:1.17.9）-d 后天運(yùn)行哦
bd002733203d169f691eacfcd183af7e4132efafb2c9d52d560ff4a844f25bb3

http://localhost:8080/

3. docker ps 看進(jìn)程

>> docker ps
CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS                  NAMES
bd002733203d   nginx:1.17.9   "nginx -g 'daemon of…"   7 minutes ago   Up 7 minutes   0.0.0.0:8080->80/tcp   nginx

4. docker rm 刪除容器

>>> docker rm nginx
Error response from daemon: You cannot remove a running container bd002733203d169f691eacfcd183af7e4132efafb2c9d52d560ff4a844f25bb3. Stop the container before attempting removal or force remove

docker rm -f 容器 強(qiáng)制刪除

5. docker stop 停止容器
   docker stop nginx
6. docker run 設(shè)置掛載目錄 防止誤操作影響了服務(wù)

docker run -d  --name nginx -p 8080:80 -v ./nginx/html:/usr/share/nginx/html nginx:1.17.9  

docker pull mysql：8.0.26

docker run -d --name mysql -p 3307:3307 --privileged=true -e MYSQL_ROOT_PASSWORD=123456 mysql:8.0.26

端口3306被占用

sudo lsof -i:3306
看是不是本地裝了一個(gè)mysql 并配置了開機(jī)啟動(dòng)項(xiàng)

docker  exec -it mysql bash //進(jìn)入mysql
mysql -u root -p 
password：123456
alter user 'admin'@'localhost' identified by '123456'. //增加 用戶
create database my_data
show databases
drop databases mydata
use mydata  
select version()
select now()

ahahh
