docker mysql Could not write uni

昨天在用docker部署mysql的时候一直报错

2020-06-23T09:59:47.339758Z 0 [Note] Skipping generation of SSL certificates as certificate files are present in data directory.
2020-06-23T09:59:47.340593Z 0 [Warning] CA certificate ca.pem is self signed.

解决方法：
这里可以看到mysqld.sock的目录是在/var/run/mysqld目录下，但是这个目录，我们并没有挂载主机目录，下面我们重新运行mysql容器，挂载相应的容器

 volumes:
      - /data/mysql-data:/var/lib/mysql
      - ./init:/docker-entrypoint-initdb.d/
      - /data/mysql-data/mysqld:/var/run/mysqld
