Redis (error) NOAUTH Authentication required.

首先查看redis设置密码没

127.0.0.1:6379> config get requirepass
1) "requirepass"
2) ""

　表示没有设置密码，设置redis密码

127.0.0.1:6379> config set requirepass "acy123@@"
OK

　这个时候查看密码是会报错的。

127.0.0.1:6379> config get requirepass
(error) NOAUTH Authentication required.

需要noauth身份验证。

127.0.0.1:6379> auth acy123@@
OK
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) "acy123@@"
127.0.0.1:6379>

修改密码

127.0.0.1:6379> config set requirepass "123456"
OK
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) "123456"
127.0.0.1:6379> auth acy123@@
(error) ERR invalid password
127.0.0.1:6379>
