创建mysql用户、用户组及目录
groupadd -r mysql && useradd -r -g mysql -s /bin/false -M mysql

设置权限并初始化 MySQL 系统授权表
chown -R mysql:mysql .

MySQL 5.7.6之前的版本执行这个脚本初始化系统数据库 
./bin/mysql_install_db --user=mysql --basedir=/root/mysql --datadir=/opt/data
5.7.6之后版本初始系统数据库脚本
mysqld --initialize-insecure --user=mysql --basedir=/root/mysql --datadir=/opt/data
注意：   
MySQL之前版本mysql_install_db是在mysql_basedir/script下，MySQL 5.7直接放在了mysql_basedir/bin目录下。    
"--initialize"已废弃,生成一个随机密码(~/.mysql_secret)    
"--initialize-insecure"不会生成密码    
"--datadir"目录下不能有数据文件

生成密钥到/opt/data
mysql_ssl_rsa_setup
