我正在尝试在 rkt 中设置 LEMP 堆栈（使用 Docker 文件），因此我使用 Supervisord 让所有内容在同一个容器中运行。当我单独构建并启动 Mariadb 容器时，它运行良好。当我尝试通过 Supervisord 运行它时，MariaDB 会立即退出。我做错了什么？
我也想将 Supervisord 用于其他用途，因此每次运行时我都会发送此信息：
RUN printf "\n[program:mysqld]\ncommand=sleep 5; mysqld_safe --skip-syslog\nstartretries=10\n" >> /etc/supervisor/conf.d/supervisord.conf
我为了测试目的添加了 Sleep 5 和 startretries。
错误日志如下：

没有任何错误，它只是开始关闭。
有想法吗？

好的，最终我让它运行了。我添加了在这里找到的两件事：https://github.com/Kloadut/dokku-md-dockerfiles/tree/469a32ed0696803808cd07413f13ee22c7b0e6e2
# prevent apt from starting mariadb right after the installation RUN printf '#!/bin/sh\nexit 101' > /usr/sbin/policy-rc.d; chmod +x /usr/sbin/policy-rc.d
搭配：
# allow autostart again RUN rm /usr/sbin/policy-rc.d
然后另一件事是我正在运行一个脚本文件，执行一些安全安装数据库的操作，它以以下内容结束：
tail -f /var/log/mysql.log /var/log/mysql.err /var/log/mysql/mariadb-slow.log
就是这样。真的不知道为什么没有这些会导致 MariaDB 停止，因为我没见过它们在其他地方使用。tail -f 的事情特别奇怪，因为我认为 Supervisord 会处理它。
无论如何，如果其他人也遇到这种情况，请查看上面链接中的 Dockerfile 和脚本文件。对我来说这就是全部了。
