使用默认值安装，我已经安装了mysql 5.7.13。从源使用从这里的指令：https://dev.mysql.com/doc/refman/5.7/en/installing-source-distribution.html
然后我按照这里的指示初始化数据目录：https://dev.mysql.com/doc/refman/5.7/en/data-directory-initialization.html
这是安装在我的Ubuntu 14.04服务器上。mySQL 5.7.13源码安装不创建mysqld.sock
开始使用此服务器：
bin/mysqld_safe --user=mysql &
告诉我检查日志文件error.log中。 error.log中说

和启动mysql_updgrade

我得到一个错误消息说：

现在，我仍然得到同样的问题。 socket文件根本就没有被创建，不管我说my.cnf在哪个文件夹以及哪个权限。我试图创建文件本身，但它产生相同的结果。
是的，我确定my.cnf是mySQL的默认文件。该端口在iptables中打开，mySQL用户拥有/配置mysql配置所指向的所有文件的所有权/访问权限。
我在安装了apache2的Ubuntu 14.04服务器上运行它。并且服务器在Virtual Box中运行。我通过Putty访问服务器。
我一直被困在这个日子里，并且在尝试所有可以在本网站和其他人的其他问题中找到的解决方案后，现在该做什么完全丧失。我可以提供任何和所有帮助回答这个问题所需的信息/日志。
我真的很感谢在这个问题上的任何和所有帮助！
