忘記root密碼

如果不小心忘記了root密碼，那么mysql就不能再登錄了，這時(shí)就要重置root密碼才行。通過(guò)下面的步驟，我們可以重新設(shè)置root密碼。

1 、退出mysql

[root@localhost src]#  service mysqld stop

停止 mysqld ：                                              [ 確定 ]

[root@localhost src]# 

 

2 、進(jìn)入sql安全模式，命令“ /usr/bin/mysqld_safe --skip-grant-table & ”

[root@localhost src]# /usr/bin/mysqld_safe --skip-grant-table &

[1] 6332

[root@localhost src]# 180814 10:10:00 mysqld_safe Logging to '/var/log/mysqld.log'.

180814 10:10:00 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

 

3 、無(wú)密碼方式登錄，命令“mysql –u root”

[root@localhost src]#  mysql -u root
