CentOS 下 MySQL root 密碼重設
CentOS 下 重設MySQL密碼的方法有很多,官網也提供了很方便的快捷操作辦法,可參考資料 resetting permissions 。本文重設密碼的具體步驟如下:
一、停止MySQL(如果處於運行狀態)
#service mysqld stop
輸出
Shutting down MySQL. [ OK ]
關於 #service mysqld stop 命令,可參考 CentOS 6.5 平台離線編譯安裝 MySQL 5.6.22。
二、啟動MySQL_safe,如此以來便可不用密碼登入MySQL
# mysqld_safe --skip-grant-tables &
輸出類似
Starting mysqld daemon with databases from /var/lib/mysql
mysqld_safe[6025]: started
三、登入MYSQL
# mysql -u root
輸出
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 4.1.15-Debian_1-log
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
四、設定新密碼
mysql> use mysql;
mysql> update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
mysql> flush privileges;
mysql> quit
五、停止MySQL
# /etc/init.d/mysql stop
輸出
Stopping MySQL database server: mysqld
STOPPING server from pid file /var/run/mysqld/mysqld.pid
mysqld_safe[6186]: ended
[1]+ Done mysqld_safe --skip-grant-tables
六、啟動MySQL並測試新密碼是否正確
# /etc/init.d/mysql start
# mysql -u root -p
CentOS 6.4下安裝MySQL後重設root密碼方法
