mysql 5.7.17 绿色版安装配置

新下载了个MySql。启动报错“mysql 服务无法启动 服务没报告任何错误”

最新版本的安装方式

1.下载解压到C:\mysql目录

2.修改default.ini为my.ini，并配置以下内容

[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=C:\mysql
datadir = C:\mysql\data
# 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

3.将C:\mysql\bin 加入到环境变量

4.mysqld --initialize-insecure 初始化一个空密码的root用户（创建了data文件夹）

5.mysqld --install MySQL --defaults-file="C:\MySql\my.ini"   安装mysql服务到系统

6.net start mysql
