【问题描述】：

我在通过 mysql 工作台连接到我的 mysql 时遇到问题。当我创建连接并单击测试连接时，1-2分钟后它说： failed to connect to MySQL at xxx:3306 with user root. Lost connection to MySql server at 'waiting for initial communcation packet', system error: 10060 当我在几分钟后单击连接时，它会崩溃。

我在 ubuntu 18 服务器上运行 mysql 数据库。我没有其他防火墙，并且我已经使用“ufw disable”命令禁用了 ufw。 我还注释掉了配置文件中的绑定地址行。 整个配置文件如下：

# The MySQL database server configuration file.

# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
# One can use all long options that the program supports.
# Run 

program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
# Remember to edit /etc/mysql/debian.cnf when changing the socket location.

# Here is entries for some specific programs
# The following values assume you have at least 32M ram

[mysqld_safe]
socket      = /var/run/mysqld/mysqld.sock
nice        = 0

[mysqld]
#
# * Basic Settings

datadir     = /var/lib/mysql
tmpdir      = /tmp

skip-external-locking
#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.

#
key_buffer_size     = 16M
max_allowed_packet  = 16M
thread_stack        = 192K

#
# * Logging and Replication
#
# Both location gets rotated by the cronjob.
# Be aware that this log type is a performance killer.
# As of 5.1 you can enable the log at runtime!
#general_log_file        = /var/log/mysql/mysql.log
#general_log             = 1
#
# Error log - should be very few entries.

#slow_query_log_file    = /var/log/mysql/mysql-slow.log
#long_query_time = 2
#log-queries-not-using-indexes
#
# The following can be used as easy to replay backup logs or for replication.
# note: if you are setting up a replication slave, see README.Debian about
#       other settings you may need to change.
#server-id      = 1
#log_bin            = /var/log/mysql/mysql-bin.log
expire_logs_days    = 10
max_binlog_size   = 100M
#binlog_do_db       = include_database_name
#binlog_ignore_db   = include_database_name
#
# * InnoDB
#
# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more InnoDB related options. There are many!
#
# * Security Features
#
# Read the manual, too, if you want chroot!
# chroot = /var/lib/mysql/
#
# For generating SSL certificates I recommend the OpenSSL GUI "tinyca".
#
# ssl-ca=/etc/mysql/cacert.pem
# ssl-cert=/etc/mysql/server-cert.pem
# ssl-key=/etc/mysql/server-key.pem

我还授予了 root 上的所有权限，如下所示：

grant all privileges on *.* to 'root'@'%' identified by 'xxx';

当我运行 netstat -plan| 时grep 3306 。我明白了：

tcp6   0    0  :::3306         :::*        LISTEN 27233 /mysqld

这意味着服务器已准备好从远程 ip 监听。

【参考方案1】：

向所有用户授予权限，但这不是好的做法。

GRANT ALL ON .* TO ''@'%' IDENTIFIED BY 'yourdbpassword'; 刷新特权；
