Redis cache details, redis details
Let's officially share today's article:
. Set up the Redis server and connect it with the client
. Encapsulate the cache parent class and define common methods such as Get and Set.
. Define the RedisCache
Label:In a multi-node project, it is often related to some method lock control. At this time, the easy-to-use synchronized has been unable to meet the multi-node deployment structure. Earlier in the project, more of the database's update locks were used: for udpate. But this has a disadvantage, that is, it is prone to bottlenecks in the database, resulting in greater pressure. At the same time, if the statement of the lock table, the table data volume is particularly large, the basic server dire

As mentioned above, the iis7 arr module can be used to implement nginx-like reverse proxy and provide a load balancing solution. However, to deploy it in actual applications, you must solve the session synchronization problem, session is actually a type of cache. In the previous Microsoft solution, there was no reliable distributed

After the Mysql result set is cached in the Redis string or hash structure, we are faced with a new problem, such as what these strings or hash names are, that is, how to determine their keys. Because the rows corresponding to these data

Two problems must be solved when Redis is used as the Mysql database cache. First, determine the data structure used to store data from Mysql. After determining the data structure, consider the id

Now when we access the cache, we only need to link to the cache server:
$mem = Memcache_connector ("artical20180120.html");

data items. If you are using PHP to write dynamic content:
$mem = Memcache_connect ("192.168.88.88", 11211);
$mem->add ("Item_key", "Item_value", false,30);
Set the expiration time of this data item to 30 seconds for Item_key. Network concurrency Model
