Specific question: When running redis in LNMP environment, the following error "PHP Fatal error: Uncaught exception 'RedisException' with message 'Connection closed' in" appears. How to solve it?

The best adopted answer:

I just encountered this problem today. The solutions found online (such as setting connection timeout, etc.) are invalid. Solve it yourself and then answer it:

Redis check---- -------------------------->

1. Check whether the redis service is started: ps -ef | grep redis

2. OK The port number that redis runs on: such as the default 6379

3, telnet 127.0.0.1 6379. If the connection fails, check the firewall settings and open port 6379

4. Redis configuration check: timeout 0 (no timeout) in redis.conf, bind 127.0.0.1 (If redis is not used locally, configure the user machine IP for ip, or set it directly to 0.0.0.0 without restrictions)

PHP setting check---------------- -------------->

1. Determine whether PHP has the redis extension installed: extension = redis.so has been configured in php.ini, and redis.so exists

2. Check the php.ini file: default_socket_timeout = 600 (unit is s, set at least 60s)

The most important thing, if you use redis to manage sessions, then check the php.ini file:

session.save_handler = redis

session .save_path = "tcp://127.0.0.1:6379" (The redis ip and port here must be set correctly!)
