redis basic operation commands (simple)

 

1, and installation of related presentations redis redis, please see [ rookie tutorial ].

2, preparation, know a few shell commands.

3, repeat官网【Redis】.

4, into the theme: redis command.

5, Description: I am here for easy to use and is installed under Windows redis learn its basics. General use, then still need to put Linux in learning.

6, the overall experience of learning redis: Simple

Redis basic data types are five categories: String type, list types, set type, zset type, hash type. Therefore, according to this exemplary command explain five categories of data types:

First, the operation command string type :

1. Insert string types of data structures 
set keyname1 keyValue - Key insertion type string Redis
2. Get string types of data structures
GET KeyName1
3. Delete Key
del KeyName1

 

Other common commands are as follows: 
1, to get the string key string value (Note: This is only the substring key interception return in the show, the real key is the same value or if you need to change the key of value, you can use the following command getset)
GetRange Key Start End

Demo:

2. The old values of existing key to re-set, and returns the key of 
getset key value

Example:

3 . Get plurality Key 
mget key1 [key2 ,,,,,,]

Example:

4 . Redis increment key 
incr key

Example: Each input the same command incr increamentKey, the value of this key is incremented by one.

Further, incr specified increment step size, incrby key increment

Specifies that increased step when execution of commands.

5 For key string already exists stitching again. 
append key value

Example:

 More commands: See [ more redis string commands ]

Second, hash HASH

1 , insert a hash field structure 
HSET Key value
 2 , to delete the one or more hash Field 
 HDEL Key Field [ Field2 ] value

Example:

3 . Gets the hash table number of fields 
hlen hset1

4 . Gets all the values given field 
hmget Key field1 [ Field2 ... ]

5 while the plurality Field. - value (Domain - value) provided to the hash table key in. 
HMSET Key field1 VALUE1 [ Field2 value2 ] 
6 . Only in the field when the field is not present, provided the hash table field values 
hsetnx Key field value

Example:

7 iterative hash table key-value pairs 
HASCAN Key  Cursor  [ the MATCH pattern ]  [ COUNTcount ]

Third, the list List

dfds
