mysql mysql自動修改密碼 mysql忘記密碼 mysql強制修改密碼 如果不記得mysql的root密碼，那麽就只能強制修改密碼了，使用shell輕松自動修改密碼:
#!/bin/bash #Author Aiker PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin export PATH read -p "Please input your new password:" c pwd=$c service mysqld stop mysqld_safe --skip-grant-tables& echo ‘正在修改密碼...‘; echo ‘The set password...‘; sleep 6 mysql -uroot -e "insert into mysql.user(Select_priv,Insert_priv,Update_priv,Delete_priv,Create_priv,Drop_priv,Reload_priv,Shutdown_priv,Process_priv,File_priv,Grant_priv,References_priv,Index_priv,Alter_priv,Show_db_priv,Super_priv,Create_tmp_table_priv,Lock_tables_priv,Execute_priv,Repl_slave_priv,Repl_client_priv,Create_view_priv,Show_view_priv,Create_routine_priv,Alter_routine_priv,Create_user_priv,Event_priv,Trigger_priv,Create_tablespace_priv,User,Password,host)values(‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘root‘,password(‘${pwd}‘),‘127.0.0.1‘)" mysql -uroot -e "insert into mysql.user(Select_priv,Insert_priv,Update_priv,Delete_priv,Create_priv,Drop_priv,Reload_priv,Shutdown_priv,Process_priv,File_priv,Grant_priv,References_priv,Index_priv,Alter_priv,Show_db_priv,Super_priv,Create_tmp_table_priv,Lock_tables_priv,Execute_priv,Repl_slave_priv,Repl_client_priv,Create_view_priv,Show_view_priv,Create_routine_priv,Alter_routine_priv,Create_user_priv,Event_priv,Trigger_priv,Create_tablespace_priv,User,Password,host)values(‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘Y‘,‘root‘,password(‘${pwd}‘),‘localhost‘)" mysql -uroot -e "UPDATE mysql.user SET password=PASSWORD(‘${pwd}‘) WHERE user=‘root‘"; mysql -uroot -e "UPDATE mysql.user SET authentication_string=PASSWORD(‘${pwd}‘) WHERE user=‘root‘"; mysql -uroot -e "FLUSH PRIVILEGES"; pkill -9 mysqld_safe pkill -9 mysqld sleep 2 service mysqld start echo ‘===========================================‘ echo "mysql root密碼成功修改為: ${pwd}" echo "The root password set ${pwd} successuful"
測試效果：
