才裝完的mysql,轉(zhuǎn)眼密碼就忘記了，找了一圈的修改密碼方法窗声，做下記錄相恃！
- 編輯mysql配置文件。
[root@localhost ~]# vi /etc/my.cnf
- 在
[mysqld]配置節(jié)下新增skip-grant-tables笨觅。
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-grant-tables
# Disabling symbolic-links is recommended to prevent assorted security risks
