I connected the slave redis, what a silly mistake -_-!!!
The learn is that we should always check server status before jumping into client code .
I'm trying to use redis in a php app, as google result, I choose phpredis. I established the connection, successfully got redis info by $this->_redis->info()
, but failed to set any value. here are some software info:
php : 5.5.19 x64 thread safe
framework : CodeIgniter(sorry I don't know where to get version info)
redis : 2.8.15
phpredis : php_redis-2.2.7-5.5-ts-vc11-x64
And a helper class contains connection configuration and functions
class Redis_Module{
private $_redis;
function __construct(){
$this->ci = & get_instance();
$redis_connection_array = $this->ci->config->item('redis_connection_array');
$this->_redis = new Redis();
$this->_redis->connect($redis_connection_array['host'],$redis_connection_array['port']);
$this->_redis->auth($redis_connection_array['password']);
}
function info(){
return $this->_redis->info();
}
function get($key){
return $this->_redis->get($key);
}
function set($key, $value){
return $this->_redis->set($key, $value);
}
}
When I call these 3 functions, I can successfully get redis info, but both set('foo', 'bar') and get('foo') functions return false, especially get('an_existing_key') returns correct info cached in redis.
$redis_client = new Redis_Module();
$msg1 = $redis_client->set('foo', 'bar');
$msg2 = $redis_client->get("foo");
$msg3 = $redis_client->get("an_existing_key");
$msg4 = $redis_client->info();
I'm not familiar with php so am I missing any critical config or anything else?
