many new usages can be created. Of course, hopefully this feature will not have an impact on the memory storage performance of Redis's original very cow B.9. Redis modifies persistent paths and log pathsThe code is as follows:Vim redis.confLogfile/data/redis_cache/logs/redis.log #日志路径 #p# page title #e#Dir/data/redis_cache #持久化路径, make sure to copy the Dump.rdb persistent file to/data/redis_cache after modification.Kill

. TYPE Key O (1) Gets the type of the value associated with the key specified in the parameter, which is returned in the form of a string. The strings returned are string, list, set, hash, and zset, if key does not exist return none SORT key [by pattern] [LIMIT offset count] [get pattern [get pattern ...]] [asc| DESC] [ALPHA] [STORE destination] O (N+m*log (M)) This command is relatively complex, so we just give the most basic usage here, and interested

; Rpop Key Here is a good understanding, respectively, from the left pop-up, from the right pop-up, the return value is a pop-up value. (pop-up means to remove the value and return the value) Combined with the above four commands, you can implement stacks and queues. Stacks: Lpush and Lpop or using Rpush and Rpop. Queues: Lpush and Rpop or using Rpush and Lpop. 3, get the number of elements in the list Shell Redisgt;llen Key 1

The following are some of the most commonly used basic commands under the Redis command line, which you can refer to for your study: 1. "Set key value" is stored in a key and value. such as: Set MyName reson2. "Get Key" reads the value of a key.3. "Del key" deletes a key.4. "Del key1 key2 ... keyn" deletes more than one key. such as: Del myname1 myname25. "Exists key" to determine whether a key exists.6. "

In the previous article, we tested and tested the existing redis data structure (see ). We will test some common redis commands today: You need to check the data volume of the current database. There are three methods: keys *, dbsize, and info (there are many data parameters, which are also frequently used recently) [Root @ fsailing1 bin] #./

7. Basic Redis commands-task queue and redis queue1. Advantages: loose coupling is easy to expand, and consumers can expand multiple servers.2. LPUSH RPOP3. The BRPOP command is similar to RPOP. The only difference is that when there are no elements in the list, the BRPOP command will always block the link and know that new elements are added.4. If the value of B

introduction of common data types: There are five data types used by Redis: String,hash,list,set,zset (sorted set). 1. String Type String is the simplest type, and a key corresponds to a value of type string with a maximum of 1G. A string type can be treated as an integer, allowing the "INCR" command family to operate (Incrby, DECR, Decrby), in which case the value of the integer is limited to 64-bit signed numbers. The separate element types contai
