我一直在按照手册在Ubuntu上安装软件套件。我完全不了解MySQL。我已经在我的Ubuntu上完成了以下安装。
sudo apt-get update
sudo apt-get install mysql-server-5.5
sudo apt-get install mysql-client-5.5
sudo apt-get install mysql-common
sudo apt-get install glade
sudo apt-get install ntp
然后我做了
cd ~/Desktop/iPDC-v1.3.1/DBServer-1.1
mysql -uroot -proot <"Db.sql"
我最终得到以下错误消息。
错误1045(28000):拒绝访问用户'root'@'localhost'(使用密码:YES)
我该如何修复它并继续?
如果其他答案都不适合您,并且您收到了以下错误:
mysqld_safe Logging to '/var/log/mysql/error.log'.
mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.
[1]+ Exit 1 sudo mysqld_safe --skip-grant-tables
按照以下命令依次执行,直到重置密码:
# Stop your server first
sudo service mysql stop
# Make the MySQL service directory.
sudo mkdir /var/run/mysqld
# Give MySQL permission to work with the created directory
sudo chown mysql: /var/run/mysqld
# Start MySQL, without permission and network checking
sudo mysqld_safe --skip-grant-tables --skip-networking &
# Log in to your server without any password.
mysql -u root mysql
# Update the password for the root user:
UPDATE mysql.user SET authentication_string=PASSWORD('YourNewPasswordBuddy'), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';
# If you omit (AND Host='localhost') section, it updates
# the root password regardless of its host
FLUSH PRIVILEGES;
EXIT;
# Kill the mysqld_safe process
sudo service mysql restart
# Now you can use your new password to log in to your server
mysql -u root -p
# Take note for remote access. You should create a remote
# user and then grant all privileges to that remote user
在服务器初始启动时,假设服务器的数据目录为空,会发生以下情况:
完成服务器的初始化。
在data目录下生成SSL证书和密钥文件。
安装并启用validate_password插件。
创建超级用户帐户“root”@“localhost”。超级用户的密码被设置并存储在错误日志文件中。
要显示它,使用以下命令:
Shell > sudo grep '临时密码' /var/log/mysqld.log
请使用临时密码登录,并自定义超级用户密码,尽快修改root用户密码:
Shell > mysql的root -p
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass5!
