docker中的crontab，重启之后没了怎么办

Posted 2023-05-12

参考技术A docker启动mysql(转）
cs202@cs202-devbox:~$ sudo docker run -d mysql
7698fdd7a2d05d38cf19c60cc9e35c1117fc551ae5e319144947154f4f353d23
cs202@cs202-devbox:~$ sudo docker ps

cs202@cs202-devbox:~$ sudo docker ps -a

257646e19a08 ubuntu "/bin/bash" 27 minutes ago Up 13 minutes desperate_ardinghelli
发现并没有成功启动，查看日志：
cs202@cs202-devbox:~$ sudo docker logs desperate_swanson
error: database is uninitialized and password option is not specified
You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD

于是设置MYSQL_ROOT_PASSWORD：
sudo docker run -e MYSQL_ROOT_PASSWORD=wwwwww --name mysql -d mysql
总算启动成功了：
^Ccs202@cs202-devbox:~sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b50461bd8135 mysql "/entrypoint.sh mysql" 4 minutes ago Up 4 minutes 3306/tcp mysql
257646e19a08 ubuntu "/bin/bash" 37 minutes ago Up 23 minutes desperate_ardinghelli
cs202@cs202-devbox:~$
后台打印出大片日志：
cs202@cs202-devbox:~$ sudo docker logs -f mysql

win10的电脑重启更新，然后usb接口没有反映了，蓝牙也没了，怎么办？

建议安装百度卫士，检测系统是否有病毒侵入，导致无法识别USB。不是的话，可以从新安装USB驱动。
1、逐步的点击并打开击“控制面板”、“管理工具”和“服务”等选项卡;
2、将Plug
and
Play服务开启使用;
3、如果Plug
and
Play服务是默认开启的，那么首先要禁止，接着再次重新开启;
4、接着将设备管理器打开，将Unknown
Device设备卸载了，然后将无线设备拔出去。等到电脑重启之后再插到电脑上，重新安装一下驱动就可以解决了。 参考技术A 可以从新安装usb驱动。
