MySQL無法重置「root」密碼

Question

我試圖按照所有建議here但沒有爲我工作。我已經在Fedora上安裝了mysql社區服務器mysql-community-server-5.7.9-1.fc21.x86_64

我試圖使用 sudo grep 'temporary password' mysqld.log訪問臨時密碼，但它不返回任何密碼。

我不斷收到錯誤 Access denied for user 'root'@'localhost' (using password: NO)

當我執行mysqld_safe的--skip-贈款表

2016-06-14 10:46:00 3495 mysqld_safe: Logging to '/var/log/mysqld.log'. chown: invalid user: ‘@MYSQLD_USER@’ 2016-06-14 10:46:00 3495 mysqld_safe: The file @libexecdir@/mysqld does not exist or is not executable. Please cd to the mysql installation directory and restart this script from there as follows: ./bin/mysqld_safe& See http://dev.mysql.com/doc/mysql/en/mysqld-safe.html for more information

我不能重新設置root的用戶密碼我得到這個錯誤。請幫忙。

Answer 1

RESET MySQL root密碼（對於Linux用戶）

登入根用戶和運行

Step 1# /etc/init.d/mysql stop 
Step 2# mysqld_safe --skip-grant-tables & 
Output : Starting mysqld daemon with databases from /var/lib/mysql mysqld_safe[6025]: started 

Step 3 Login to new terminal (with root user) 

    [#] mysql -u root 

mysql> use mysql; 
mysql> update user set password=PASSWORD('NEW-ROOT-PASSWORD') where User='root'; 
mysql> flush privileges; 
mysql> quit 

Step 4 # Stop MySQL Server: 

/etc/init.d/mysql stop 

Step 5 # /etc/init.d/mysql start 

mysql -u root -pNEWPASSWORD
