pxc 进入容器中 对mysql进行 restart操作 整个容器直接挂掉了

Question

1. pxc 进入容器中 对mysql进行 restart操作 整个容器直接挂掉了

2. 我pull了一个 percona server 进入容器后 对其 restart操作容器也会挂掉 这是为什么呢 ？？

如果这样的话 那我想修改配置文件中的参数 岂不是没办法重启？ 或者说 只能启动容器的时候 替换配置文件。。

以下是log 给老师作为参考

进入容器打开/entrypoint.sh文件，里面最后一句话是这么写的

也就是说容器启动时候没加载配置文件，在mysqld后面加的参数信息。你想改什么东西就在配置定义一个配置文件，然后让mysqld加载配置文件即可。还有不要再容器里restart mysql，把容器停掉，然后重新启动容器。还有容器启动闪退问题，解决办法参考本课程文档部分，讲解的很清楚。
