安装mysql库
adson@adson-ThinkPad-T450:/var/mysql$ sudo mkdir data_3306
adson@adson-ThinkPad-T450:/var/mysql$ sudo vi my.cnf
[mysqld]
port=3306
datadir=/var/mysql/data_3306
log_error=/var/mysql/data_3306/error.log
basedir=/var/mysql/
innodb_status_file=1 ##启用InnoDB的status file，便于管理员查看以及监控等

adson@adson-ThinkPad-T450:/var/mysql$ sudo groupadd mysql
adson@adson-ThinkPad-T450:/var/mysql$ sudo useradd -g mysql mysql

adson@adson-ThinkPad-T450:/var/mysql$ sudo chown -R mysql /var/mysql/data_3306/
adson@adson-ThinkPad-T450:/var/mysql/data_3306$ sudo /var/mysql/bin/mysqld --defaults-file=/var/mysql/my.cnf --initialize --user=mysql

密码安全：
5.7提供了一种兼容模式，在初始化数据库时可使用参数–initialize-insecure,这样一来，其行为就与5.6版本之前的一样了。
这种方法给自动化运维带来了方便，但是背离了5.7这种处理方式的初衷，所以需要想清楚这个可能造成的不安全因素。
