mysql-secure-installation错误-套接字

如何解决mysql-secure-installation错误-套接字

我在尝试进行MysqL-secure-installation时遇到错误： 错误：无法通过套接字“ /var/run/MysqLd/MysqLd.sock”连接到本地MysqL服务器（2） 命令'/ bin / sh -c DEBIAN_FRONTEND = noninteractive && MysqL_secure_installation --user root --host localhost'返回非零代码：1

我使用以下dockerfile并以这种方式构建映像：sudo docker build -t hello。

我的docker-entrypoint.sh：

任何人都可以帮忙吗？

解决方法

我对dockerfile和入口点脚本进行了一些修改，因此它现在可以工作了。为了以root用户身份运行mysqld，我使用了该命令：

`mysqld --pid-file=/var/run/mysqld/mysqld.pid --user=root -D` 

所以我的pid文件不再位于可访问的/ tmp /文件夹中，而是其他位置。然后，要连接数据库，我修改了php.ini文件，添加了以下几行：

mysqli.default_socket =/run/mysqld/mysqld.sock
mysqli.default_host = localhost
mysqli.default_user = root

我必须将其添加到wp-config.php文件中：

`define('WP_ALLOW_REPAIR',true);

这是已知的dockerfile：
