Linux下MySQL 5.7.23无法远程连接解决方案(一)

Tags:Linux MySQL 5.7.23 无法 远程 连接 解决方案

MySQL 版本:5.7.23
操作系统:Linux
问题描述:
只能通过Linux系统账号Root命令行进入数据库,无法使用JDBC,远程连接工具进入数据库
报错:ERROR 1698 (28000): Access denied for user 'root'@'localhost'
这个问题明显就是没有开放远程连接授权,所以导致只能使用Linux的Root账号登录。


解决流程


1.找到/etc/mysql/mysql.conf.d/mysqld.cnf文件,在[mysqld]最后面加skip-grant-tables


#
# 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
#
user        = mysql

tmpdir      = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
# 加入的内容,开启跳过权限校验
skip-grant-tables
#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.

# * Fine Tuning

thread_cache_size      = 8
# This replaces the startup script and checks MyISAM tables if needed

#max_connections        = 100
#table_open_cache      = 64
#thread_concurrency    = 10
#
# * Query Cache Configuration
#
query_cache_limit  = 1M
query_cache_size        = 16M
#
# * 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.
#
log_error = /var/log/mysql/error.log
#
# Here you can see queries with especially long duration
#slow_query_log    = 1
#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
