1.先停止數據庫服務器
service mysqld stop
2.vim /etc/my.cnf
3.配置文件添加skip-grant-tables
[root@VM_0_8_centos ~]# vim /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/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 此處！！！！！！
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
4.重啟數據庫
systemctl restart mysql
5.登錄數據庫
mysql -uroot -p
如果詢問密碼，直接空密碼登錄
6.set password for root@localhost = password('123456');括號里面的密碼你自己修改。
7.mysql -uroot -p123456 登錄成功
PS：下面看下Mysql初始化root密碼和允許遠程訪問
mysql默認root用戶沒有密碼，輸入mysql –u root 進入mysql
1、初始化root密碼
進入mysql數據庫
mysql>update user set password=PASSWORD(‘123456') where User='root';
2、允許mysql遠程訪問,可以使用以下三種方式:
a、改表。
mysql -u root –p
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
b、授權。
例如，你想root使用123456從任何主機連接到mysql服務器。
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
如果你想允許用戶jack從ip為10.10.50.127的主機連接到mysql服務器，并使用654321作為密碼
mysql>GRANT ALL PRIVILEGES ON *.* TO 'jack'@'10.10.50.127' IDENTIFIED BY '654321' WITH GRANT OPTION;
mysql>FLUSH RIVILEGES
c:在安裝mysql的機器上運行：
//進入MySQL服務器
d:\mysql\bin\&;mysql -h localhost -u root
//賦予任何主機訪問數據的權限
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION
//使修改生效
mysql>FLUSH PRIVILEGES
//退出MySQL服務器
mysql>EXIT
