您无权操纵用户

Question

我的xampp phpadmin 没有让我选择为mysql 添加用户。我到处检查，找不到解决方案。这是我在config.inc.php、my.ini 和wp-config 中的代码，来自

config.inc.php

<?php
/*enter code here

$cfg['blowfish_secret'] = 'xampp'; /* YOU SHOULD CHANGE THIS FOR A MORE SECURE COOKIE AUTH! */

$i++;

# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client] 
# password       = your_password 
port            = 3306

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id   = 1

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended

我添加了一个新的db，但无法创建用户，甚至当我选择 root 用户时，我在建立连接时遇到错误

我打算为wordpress 网站创建一个数据库，并为该database 创建一个用户

Answer 1

尝试在config.inc.php中设置这个选项：

$cfg['Servers'][$i]['DisableIS'] = true;

它对我有用。

Answer 2

在 Ubuntu 20.04 上升级到 MySQL 8.0 后，我遇到了类似的问题，尽管先卸载了 MySQL。问题是我没有删除存储在 /var/lib/mysql 中的 mysql 模式，并且随着升级，user 表中的列数发生了变化。似乎安装程序“作为一种安全机制”更改了此表中的权限，可以在 mysql 命令行控制台中为每个单独的权限修复如下：

UPDATE mysql.user SET Grant_priv = 'Y' WHERE user = 'phpmyadmin' AND host = '本地主机';

Answer 3

我有同样的问题，删除xampp并重新安装后，解决了这个问题。 我建议你删除并重新安装 xampp 程序。

注意。如果删除 xampp 程序，htdocs 文件夹中的所有内容 删除。
