初始化
/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql(如果这里报错，就指定为--datadir=/usr/local/mysql/data)
--initialize为随机生成mysql密码，注意初始化最后一行是root用户密码(例如root@localhost: ,5j1Qj_LLAek)
/etc/init.d/mysqld start
mysql5.7以上密码重置方法
vim /etc/my.cnf 加入一行mysqld--skip-grant-tables
mysql 登录 use mysql;
update user set authentication_string=password("new_pass") where user="root";
flush privileges;
如果报错ERROR 1820 (HY000): You must reset your password using ALTER USER statement；
SET PASSWORD = PASSWORD('123456');
如果出现ERROR 1819 (HY000): Your password does not satisfy the current policy requirements；
set global validate_password_policy=0; set global validate_password_mixed_case_count=2;（取消密码强度）
SET PASSWORD = PASSWORD('123456');
Mysql5.7.17开启远程连接：
mysql -uroot –p
use mysql;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
flush privileges;
select host,user from user;(查看所有用户)
