ubuntu docker mysql [ERROR] InnoDB: Unable to lock ./ibdata1 error: 11； Access denied for user 'root'@'localhost'

docker mysql  忽然自动挂掉的解决方法：

创建docker 容器步骤：

docker pull mysql:5.7.17


1 . 启动 - 自定义配置
docker run  --name mysql_01   \
-p 3306:3306  \
-v  /home/test/docker/mysql/3306/conf:/etc/mysql/mysql.conf.d \
-v /home/test/docker/mysql/3306/data:/var/lib/mysql  \
-v /home/test/docker/mysql/3306/logs:/var/log/mysql \
-e MYSQL_ROOT_PASSWORD=123456  \
 -d mysql:5.7.17

docker exec -it 7388ab22f6ca sh
mysql -uroot -p123456;
use mysql;
CREATE USER myuser@'%'  IDENTIFIED BY '123456';
grant all on *.* to myuser@'%'  with grant option; 
flush privileges;　

某一天容器忽然停掉了。

我的解决方法：

 ps -ef | grep mysqld

 kill -9 20189

docker rm mysql_01

docker run  --name mysql_01   \
-p 3306:3306  \
-v  /home/test/docker/mysql/3306/conf:/etc/mysql/mysql.conf.d \
-v /home/test/docker/mysql/3306/data:/var/lib/mysql  \
-v /home/test/docker/mysql/3306/logs:/var/log/mysql \
-e MYSQL_ROOT_PASSWORD=123456  \
-d mysql:5.7.17

----------------------------
docker logs mysql_01

执行如下操作：

 docker ps -a     如果mysql_01   Exit(1) 表示有error   

docker logs mysql_01   ./ibdata1 error: 11；

 如果报错 参考： https://severalnines.com/blog/mysql-docker-containers-understanding-basics        【non-zero value】

重新登录，报错：

docker exec -it mysql_01 sh
# mysql -uroot -p
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

# mysql -uroot -p123456 -P3306 -h 192.168.205.122
