【问题描述】：

我正在尝试使用containerd 运行 MySQL 容器；每当我尝试运行它时，它都会引发以下错误？

错误是，套接字设置和创建锁定文件失败。我的主机没有安装 SQL 服务器。

使用来自 docker hub 的官方 MySQL 最新镜像。使用ctr 管理containerd。需要对配置进行哪些更改才能消除此错误？

ctr run  --mount type=bind,src=$PWD,dst=/context,options=rbind:ro --env MYSQL_ROOT_PASSWORD=test123 docker.io/library/mysql:latest sql1

【解决方案1】：

在/etc/mysql/my.cnf 以sql_mode = 开头的行上，尝试删除NO_AUTO_CREATE_USER，保存文件并重新启动容器。

【讨论】：

谢谢，J。我的主机是否需要运行 mysql 才能运行 SQL 容器？ MySQL 容器是否使用任何主机 MySQL 套接字/路径来启动容器？ /etc/mysql/my.conf 你指的是主机吗？请注意，我的主机没有安装任何 SQL。

【解决方案2】：

当我尝试使用 Containerd 启动 mysql 容器时，我遇到了同样的错误。我最终在主机上创建了“/var/run/mysqld/”并挂载它。

mkdir /var/run/mysqld
useradd -m mysql
chown mysql:mysql /var/run/mysqld

在权限更改为 777 之前仍有错误？

chmod 777 /var/run/mysqld


ctr --debug run --mount type=bind,src=/var/run/mysqld,dst=/var/run/mysqld,options=rbind:rw --env MYSQL_DATABASE=testdb --env MYSQL_ROOT_PASSWORD=foo --net-host docker.io/library/mysql:latest mysqldb
