windows上安装sql最容易出现 1067错误，网上查了很多，大部分都是误导。现在将验证过的步骤总结如下：
1.下载mysql，我用的是mysql-5.6.24-win32
下载后解压，进入到bin目录，修改配置文件。修改如下：
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. innodb_buffer_pool_size = 128M # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. log_bin # These are commonly set, remove the # and set as required. basedir = D:SoftMysqlmysql-5.6.24-win32 datadir = D:SoftMysqlmysql-5.6.24-win32data # port = ..... # server_id = ..... # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. join_buffer_size = 128M sort_buffer_size = 2M read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
2.用管理员身份启动命令行工具，进入到bin目录下面
执行命令：
3.修改管理员密码
默认安装后用户root密码为空
可以用命令或者用第三方工具连接到mysql，到数据库mysql的user表中直接修改。
