List is a linked list structure, and its main functions are push, pop, getting all values in a range, and so on. The key in the operation is understood as the name of the linked list.

Lrange list1 0-1

1) "123 456"

2) "aaa"

127.0.0.1 purl 6379 > lpop list1

"123456"

127.0.0.1 purl 6379 > rpush list1 aaa

(integer) 2

127.0.0.1 lrange list1 6379 > 0-1

1) "aaa"

2) "aaa"

-set

Set is a set, which is similar to the concept of set in our mathematics. There are operations such as adding and deleting elements to the set, intersection and difference of multiple sets, and so on.

Zadd myset2 12 "abc"

(integer) 1

127.0.0.1 6379 > zadd myset2 12 "abc 123"

(integer) 1

127.0.0.1 6379 > zadd myset2 12 "123-aaa"

(integer) 1

127.0.0.1 zrange myset2 6379 > positive sequence 0-1

Reverse order of zrevrange myset2 0-1

Hset hash3 name aaa

(integer) 1

127.0.0.1 6379 > hset hash3 age 10

(integer) 1

127.0.0.1 purl 6379 > set hash3 sex nan

(error) ERR syntax error

127.0.0.1 purl 6379 > hset hash3 sex nan

(integer) 1

127.0.0.1 purl 6379 > hgettall hash3

(error) ERR unknown command 'hgettall'

127.0.0.1 purl 6379 > hgetall hash3

1) "name"

2) "aaa"

3) "age"

4) "10"

5) "sex"

6) "nan"

Hget hash3 age

2.9 php uses Redis storage

Cd / usr/local/src

Wget https://codeload.github.com/phpredis/phpredis/zip/develop

Mv develop phpredis.zip

Yum install-y unzip

Unzip phpredis.zip

Cd phpredis-develop/

/ usr/local/php/bin/phpize

. / configure-- with-php-config=/usr/local/php/bin/php-config

Make

Make install

Vi / usr/local/php/etc/php.ini

Finally, add a line

Extension = redis.so

Vi / usr/local/apache2/conf/httpd.conf

# before the removal of servername

Add to lphp.ini

Session.save_handler = "redis"

Session.save_path = "tcp://127.0.0.1:6379"

Or apache virtual host to join.

Php_valuesession.save_handler "redis"

Php_valuesession.save_path "tcp://127.0.0.1:6379"

Or add to the pool corresponding to php-fpm.conf

Php_ value [session. Save _ handler] = redis

Php_ value [session. Save _ path] = "tcp://127.0.0.1:6379
