最开始的bug：表突然不能读取

关闭mysql容器，再次重启失败

解决方案

不重建容器的几种可能措施

关键的信息：

• File ./webbuild/sys_config.frm: ‘stat’ returned OS error 122.
• Operating system error number 22 in a file operation.
• File .//ib_buffer_pool: ‘stat’ returned OS error 122.
• Cannot open '/var/lib/mysql/ib_buffer_pool.incomplete’ for writing: Invalid argument
• File ./ib_logfile0: ‘Linux aio’ returned OS error 105. Cannot continue operation
• ‘/var/lib/mysql/mysql.sock’ -> ‘/var/run/mysqld/mysqld.sock’

查了下，有以下几种可能：

• dokcer在windows上的文件系统兼容问题（‘Linux aio’），重启docker(优先建议这种方法，docker引擎在window很容易出问题)
• 我的sys_config表的stat字段有问题，移除它的表文件
• 容器内存不够，mysql的缓存页空间不足（ib_buffer_pool），docker update扩容
• logfile文件问题：备份并移除logfile文件（./ib_logfile0）

除了重启没试过，其他试了都没有，我就重建容器了（因为其他容器正常就没第一时间怀疑docker），后面还是重启docker解决

重建容器

重建

docker run  --env=MYSQL_ROOT_PASSWORD=xxxx --env=PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin --env=GOSU_VERSION=1.16 --env=MYSQL_MAJOR=5.7 --env=MYSQL_VERSION=5.7.44-1.el7 --env=MYSQL_SHELL_VERSION=8.0.35-1.el7 --volume=E:\volume\mysql\mysql5.7\conf:/etc/mysql/conf.d --volume=E:\volume\mysql\mysql5.7\data:/var/lib/mysql --volume=E:\volume\mysql\mysql5.7\log:/var/log --volume=/var/lib/mysql -p 3306:3306 --restart=no --runtime=runc --memory="1073741824" -d mysql:5.7

如果懒得打命令或者忘记命令

2种方式：

• docker desktop软件
• docker commit
  

可能的run bug：xxxx file exists.

docker: Error response from daemon: error while creating mount source path '/run/desktop/mnt/host/e/volume/mysql/mysql5.7/data': mkdir /run/desktop/mnt/host/e: file exists.

docker在windows上的兼容问题，将docker重启一下，再次run ，ok
（说明最开始的mysql bug应该就是docker的文件系统兼容问题，应该重启docker就行，不用重建）
