在linux系統中安裝mysql伺服器詳細步驟並解決ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using passw


1. 提示 /tmp/mysql.sock 丟失


service mysql start


提示 /tmp/mysql.sock 丟失，則重啟伺服器，會自動建立 /tmp/mysql.sock 檔案




2. 提示 ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)


# mysql -uroot -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)






使用網上介紹的方法修改root使用者的密碼：
# mysqladmin -uroot -p password 'newpassword'
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: YES)'


現在終於被我找到了解決方法，如下（請先測試方法三，謝謝！）：
方法一：
# /etc/init.d/mysql stop
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;
mysql> quit


# /etc/init.d/mysql restart
# mysql -uroot -p
Enter password: <輸入新設的密碼newpassword>

mysql>
