本文给大家分享的是查看MySQL连接的root密码的方法,下面话不多说来来看正文:
1.首先我们进到MySQL的bin目录下
➜ cd /usr/local/mysql/bin2.切换成root身份
➜ bin sudo su3.跨过权限的验证
sh-3.2# ./mysqld_safe --skip-grant-tables &[1] 9451sh-3.2# 2017-01-03T15:40:10.6NZ mysqld_safe Logging to '/usr/local/mysql/data/yzydeMacBook-Pro.local.err'.2017-01-03T15:40:10.6NZ mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data4.以root身份登录MySQL
./mysql -urootWelcome to the MySQL monitor.

Type '\c' to clear the current input statement.5.选择mysql数据库

mysql> show tables;+---------------------------+| Tables_in_mysql |+---------------------------+| columns_priv || db || engine_cost || event || func || general_log || gtid_executed || help_category || help_keyword || help_relation || help_topic || innodb_index_stats || innodb_table_stats || ndb_binlog_index || plugin || proc || procs_priv || proxies_priv || server_cost || servers || slave_master_info || slave_relay_log_info || slave_worker_info || slow_log || tables_priv || time_zone || time_zone_leap_second || time_zone_name || time_zone_transition || time_zone_transition_type || user |+---------------------------+31 rows in set (0.00 sec)7.很明显我们需要的密码是存在user这个表下的,所以我们直接看user的表结构是怎么样的
mysql> show columns from user;+------------------------+-----------------------------------+------+-----+-----------------------+-------+| Field | Type | Null | Key | Default | Extra |+------------------------+-----------------------------------+------+-----+-----------------------+-------+| Host | char(60) | NO | PRI | | || User | char(32) | NO | PRI | | || Select_priv | enum('N','Y') | NO | | N | || Insert_priv | enum('N','Y') | NO | | N | || Update_priv | enum('N','Y') | NO | | N | || Delete_priv | enum('N','Y') | NO | | N | || Create_priv | enum('N','Y') | NO | | N | || Drop_priv | enum('N','Y') | NO | | N | || Reload_priv | enum('N','Y') | NO | | N | || Shutdown_priv | enum('N','Y') | NO | | N | || Process_priv | enum('N','Y') | NO | | N | || File_priv | enum('N','Y') | NO | | N | || Grant_priv | enum('N','Y') | NO | | N | || References_priv | enum('N','Y') | NO | | N | || Index_priv | enum('N','Y') | NO | | N | || Alter_priv | enum('N','Y') | NO | | N | || Show_db_priv | enum('N','Y') | NO | | N | || Super_priv | enum('N','Y') | NO | | N | || Create_tmp_table_priv | enum('N','Y') | NO | | N | || Lock_tables_priv | enum('N','Y') | NO | | N | || Execute_priv | enum('N','Y') | NO | | N | || Repl_slave_priv | enum('N','Y') | NO | | N | || Repl_client_priv | enum('N','Y') | NO | | N | || Create_view_priv | enum('N','Y') | NO | | N | || Show_view_priv | enum('N','Y') | NO | | N | || Create_routine_priv | enum('N','Y') | NO | | N | || Alter_routine_priv | enum('N','Y') | NO | | N | || Create_user_priv | enum('N','Y') | NO | | N | || Event_priv | enum('N','Y') | NO | | N | || Trigger_priv | enum('N','Y') | NO | | N | || Create_tablespace_priv | enum('N','Y') | NO | | N | || ssl_type | enum('','ANY','X509','SPECIFIED') | NO | | | || ssl_cipher | blob | NO | | NULL | || x509_issuer | blob | NO | | NULL | || x509_subject | blob | NO | | NULL | || max_questions | int(11) unsigned | NO | | 0 | || max_updates | int(11) unsigned | NO | | 0 | || max_connections | int(11) unsigned | NO | | 0 | || max_user_connections | int(11) unsigned | NO | | 0 | || plugin | char(64) | NO | | mysql_native_password | || authentication_string | text | YES | | NULL | || password_expired | enum('N','Y') | NO | | N | || password_last_changed | timestamp | YES | | NULL | || password_lifetime | smallint(5) unsigned | YES | | NULL | || account_locked | enum('N','Y') | NO | | N | |+------------------------+-----------------------------------+------+-----+-----------------------+-------+45 rows in set (0.02 sec)8.表的内容比较多,但是我们很容易就发现,密码其实是存在authentication_string字段下的,那我们就可以直接读User内容为root的密码了
mysql> select authentication_string from user where User='root';+-------------------------------------------+| authentication_string |+-------------------------------------------+| *781D25322166DB7FF99BA4A1FA5ED30439A60DDE |+-------------------------------------------+1 row in set (0.01 sec)OK,那我们拿着这个密码到Navicat试试看
