三、登錄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、設置新密碼
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
