1，php操作redis
function updateRedisCount($key, $count) {
$redis = new Redis();
$rcon = $redis->pconnect(REDIS_HOST, REDIS_PORT_3);
if ($rcon) {
if (!$redis->exists($key)) {
$redis->set($key, $count);
} else {
$redis->incrby($key, $count);
}
}
}
2，redis安全

3，redis 删除命令
redis-cli keys "*" | xargs redis-cli del
4，*windows redis添加服务
redis-server --service-install redis.windows-service.conf --loglevel verbose
5，redis启动方式

6，redis连接
redis-cli -h 127.0.0.1 -p 6379
6,redis每次读取10000条数据
$match = $day.':usertab:*';
while ($arr = $redis->scan($it, $match, 10000)){
foreach($arr as $k=>$v){
//
}
}
