#初始化  注：初始化时，data目录必须为空
[root@db02 /usr/local]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

#参数介绍：
  --initialize-insecure  不安全初始化，即没有密码。
  --initialize           安全初始化，会自动生成临时密码。在log-error里,查询 temporary password
  --user=mysql           初始化用户
  --basedir=/service/mysql        软件安装目录
  --datadir=/service/mysql/data   数据存放位置
