Answer 1

Why does the

key have - in the middle? You should make the key simpler, such as a

Answer 2

Can you write the command directly to see if the key can be put in?

Answer 3

It seems useless. redis->select($db);Select the database.

Answer 4

I also encountered that set returned false, and there was no specific prompt information when testing in the code. Then I went to the Linux server to test whether redis was valid. The test results showed that there was indeed a problem with set, and it prompted (error) MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error. Then go to Baidu or Google and run config set stop- according to the online method writes-on-bgsave-error no or modify sysctl vm.overcommit_memory=1 (you can try both) and it will be ok

Answer 5

pong means the link is successful. If it cannot be set, please check the log

Answer 6

I also encountered this when I was learning redis. As long as I run some error statements in the front, it will not work anymore, such as $redis->set('iliked',1);$redis->decr('iliked' ,2);//After executing this sentence, refresh the page frequently, and then write $redis->delete('iliked'); or the set operation mentioned above will not work. At this time, redis needs to be restarted. That's it. Very depressing! ! !
