PHP Redis sends read Error on connection

background

Because of the high concurrency, the project changed the connection redis from a short connection to a long connection. As a result, a Read error on connection was raised

A reason for

PHP has a configuration item default_socket_timeout that specifies the timeout period for a socket connection. The default value is 60 seconds. The underlying connection redis is the socket used by phpredis. The next time the connection throws this exception.

The solution

Option 1 Modify php.ini(not recommended)

In php.ini, set default_socket_timeout = -1 and restart php-fpm

Scheme 2 program Settings

Use the ini_set function ini_set(‘default_socket_timeout’, -1); / / no timeout

Scheme 3 uses the redis option

$this->redis->setOption(redis ::OPT_READ_TIMEOUT, -1);

Note that any timeout setting should be set to -1 instead of 0
