[root@f90140fd8427 lib]# useradd mysql
[root@f90140fd8427 lib]# su mysql
[mysql@f90140fd8427 lib]$  mysqld --initialize


二、启动mysql

[root@iZ25av9xi4hZ opt]# /etc/init.d/mysqld start
Initializing MySQL database:                               [  OK  ]
Installing validate password plugin:                       [  OK  ]
Starting mysqld:                                           [  OK  ]

查找mysql

[root@iZ25av9xi4hZ local]# find / -name mysql -print


/usr/lib64/mysql
/usr/share/mysql   mysql默认安装目录：/usr/share/mysql
/usr/bin/mysql
/etc/logrotate.d/mysql
/var/lib/mysql      data默认目录：/var/lib/mysql
/var/lib/mysql/mysql

三、修改密码

3.1修改配置文件，第一次跳过验证

3.2修改my.cnf配置文件

# sudo vi /etc/my.cnf

在[mysqld]的段中加上一句：skip-grant-tables,

如下：

[mysqld] datadir=/var/lib/mysql

socket=/var/lib/mysql/mysql.sock

skip-grant-tables

3.3启动mysql

#/etc/init.d/mysqld start

如果/etc/init.d/mysqld 则采用下面的方式
[root@f90140fd8427 mysql]# su mysql
[mysql@f90140fd8427 mysql]$ mysqld &
[1] 983
[mysql@f90140fd8427 mysql]$ exit
exit
[root@f90140fd8427 mysql]# ps -ef | grep mysql
mysql      983     1  3 06:59 ?        00:00:00 mysqld
root      1013   773  0 06:59 ?        00:00:00 grep --color=auto mysql
[root@f90140fd8427 mysql]# mysql -uroot

3.4 登录修改密码

# mysql -uroot mysql
MySQL 5.7.6 以及最新版本：

# mysql> update user set authentication_string=PASSWORD('newpass') where User='root';

MySQL 5.7.5 或更早之前的版本r:

# mysql> update user set password=PASSWORD('newpass') where User='root';

FLUSH PRIVILEGES;

3.5修改外网权限

针对所有服务器都可以访问，修改成这样

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

如果只针对能192.168.13.56服务器能够访问，修改成这样

GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.13.56' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

3.6刷新数据库

FLUSH PRIVILEGES;

3.7退出，修改/etc/my.cnf,删除原先的跳过验证，skip-grant-tables,删除

3.8 重启 数据库

#/etc/init.d/mysqld restart

3.9如果出现下面情况

You must reset your password using ALTER USER statement before executing this statement.

bogon:~ root# mysql -uroot -p
Enter password:
