docker容器不会以Mysql docker镜像开始

我使用带有mysql官方图像的docker容器来创建超过11个数据库容器(container1到container11).设置完成后,所有容器都运行正常,直到container9.在container10,它只启动约1分钟并再次停止.使用docker日志来检查容器,但我没有看到任何东西.停止container9,并重启container10.它再次运行良好.这种情况似乎只发生在我有9个mysql容器并试图提高第10个时.如果我停止其中一个,然后重新抬起它.那就没问题了.它是错误的吗?或者我想念码头桥的一些设置?

最佳答案
我想我在一周之后就遇到了解决方案,尽管我不太明白会发生什么.以下是我尝试过的,到目前为止,我可以调出最多20个mysql容器,没有任何问题.

1:尝试创建一个dummpy mysql容器进行测试

$docker run -e MYSQL_ROOT_PASSWORD=password mysql
Unable to find image 'mysql:latest' locally

并使用EAGAIN命中io_setup()的错误代码失败

2:检查aio-max-nr的当前值

$sysctl fs.aio-max-nr
fs.aio-max-nr = 65536

3:将aio-max-nr的值增加到2097152

$sudo sysctl -w fs.aio-max-nr=2097152

3:启动mysql服务

4:尝试创建更多的mysql容器,并在没有问题的情况下调出原始容器
