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/bin
2.切换成root身份
➜ bin sudo su
3.跨过权限的验证
sh-3.2# ./mysqld_safe --skip-grant-tables & [1] 9451 sh-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/data
4.以root身份登录mysql
./mysql -uroot welcome to the mysql monitor. commands end with ; or \g. your mysql connection id is 2 server version: 5.7.12 mysql community server (gpl) copyright (c) 2000, 2016, oracle and/or its affiliates. all rights reserved. oracle is a registered trademark of oracle corporation and/or its affiliates. other names may be trademarks of their respective owners. type 'help;' or '\h' for help. type '\c' to clear the current input statement.
5.选择mysql数据库
mysql> use mysql reading table information for completion of table and column names you can turn off this feature to get a quicker startup with -a database changed
6.显示mysql数据库下的表
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
