今天在window搭建一个环境，项目启动发现redis连接失败报错

刚开始以为是redis密码错误
但再次确定redis.windows.conf里的 requirepass 和项目配置的是一样的

最后网上寻找答案
在window双击redis-server.exe 后，在redis控制台会打印出下面信息

[23444] 21 Dec 08:45:16.032 # Warning: no config file specified, using the default config.

In order to specify a config file use D:\lsinstall\Redis-x64-3.2.100\redis-server.exe /path/to/redis.conf

在双击启动的时候默认去找了redis.conf的配置文件

知道原因就好解决了

方法1、
可以在redis目录下cmd运行命令：redis-server.exe redis.windows.conf
就是启动的时候去指定redis.windows.conf配置文件

方法2、
在redis目录下 start-redis.bat 内容 redis-server.exe redis.windows.conf
保存后，双击start-redis.bat即可
