This example describes the redis master-slave database status detection function implemented by PHP. We will share this with you for your reference. The details are as follows:

Instance:

<? Php/*** check whether multiple master-slave redis databases are down * create a two-dimensional array of slave database $ redis_db, the Content contains configuration data for each slave server */header ("Content-Type: text/html; charset = UTF-8"); set_time_limit (0 ); $ redis_db = array ('db1' => array ('hostname' => '2017. 0.0.1 ', 'Port' => 6379, 'Password' => '',), 'db2' => array ('hostname' => '2017. 168.2.179 ', 'Port' => 6379, 'Password' => '000000',),); $ content = ''; foreach ($ redis_db as $ db_key) {$ host = $ db_key ['hostname']; $ po Rt = $ db_key ['Port']; $ redis = new Redis (); // connect to the local Redis service $ status = $ redis-> connect ($ host, $ port); if (! $ Status) {$ content. = "redis cannot be connected from the database ($ host! <Br/> "; continue;} if (!
