Question

我正在按照本教程在我的Digital Ocean Droplet上设置MySQL服务器，但使用的是Ubuntu 16.04。

https://www.digitalocean.com/community/tutorials/how-to-migrate-a-mysql-database-to-a-new-server-on-ubuntu-14-04

当我设置＆＃39; bind-address＆＃39;作为localhost或公共服务器的ip我可以重新启动服务器，但是当我尝试使用私有ip时，我得到了一个错误。

$ sudo service mysql restart

抛出：

Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.

systemctl status mysql.service

问题是什么？

Answer 1

我也有这个问题。您刚刚在my.cnf文件中添加了什么内容？

安装时，我的my.cnf文件完全为空。当我只添加绑定地址行时，我得到了与你相同的错误。

然而，当我在它上面添加[mysqld]时，它可以工作......所以尝试添加这个：

[mysqld]
bind-address = 0.0.0.0

一些额外的信息：当我检查我的日志时，我可以看到这些错误日志，这似乎表明mysql正在my.conf文件中寻找额外的东西：

Aug 03 13:22:03 ubuntu mysql-systemd-start[19667]: my_print_defaults: [ERROR] Found option without preceding group in config file /etc/mysql/my.cnf at line 23!
Aug 03 13:22:03 ubuntu mysql-systemd-start[19667]: my_print_defaults: [ERROR] Fatal error in defaults handling. Program aborted!

我现在可以远程连接到我的数据库。

希望这有帮助！

sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/ sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.mysqld
