mysql安装

在官网下载的mysql-5.6.24-win32.zip，解压到d盘

配置环境变量path D:Program Filesmysql

创建配置文件my.ini

[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

# Set MySQL base (installed) directory  
# @@ Change to your MySQL installed directory @@  
basedir=D:Program Filesmysql 
  
# Set MySQL data directory  
# @@ Change to sub-directory "data" of your MySQL installed directory  @@  
datadir=D:Program Filesmysqldata 
  
# Run the server on this TCP port number  
port=3306
 
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
explicit_defaults_for_timestamp=true
[client]  
# MySQL client connects to the server running on this TCP port number  
port=3306

　　打开cmd，进入到安装目录的bin目录下，运行 D:Program Filesmysqlin>mysqld

出现警告[Warning] TIMESTAMP with implicit DEFAULT value is deprecated.
Please use --explicit_defaults_for_timestamp server option (see
documentation for more details).

查了下，是默认配置没开查询缓存，在配置文件加上了

explicit_defaults_for_timestamp=true

然后安装mysql

D:Program Filesmysqlin>mysqld install
Service successfully installed.

启动服务D:Program Filesmysqlin>net start mysql

出现系统错误1067，试了好多方法都没用，最后先把安装目录下耳朵data文件夹备份，删掉重新安装后，再拷回来就好使了，不知道什么鬼。。

成功进入MySQL

D:Program Filesmysqlin>mysql -u root -p
