Mageia 6, x86_64

Having tested this before, used former tests to exercize redis before updating.
redis is an in-memory data store which supports several common data formats, which data are handled via a server attached to port 6379.

Updated from redis-4.0.10-1 to redis-4.0.12-1

See https://bugs.mageia.org/show_bug.cgi?id=19158 for earlier interactive tutorial session.

The command-line tool redis-cli can be used to run scripts.

$ su
# systemctl start redis.service
# exit
$ systemctl status redis.service
● redis.service - Redis persistent key-value database

Note that errors in sysntax are trapped at the command-line while the command is being typed.  The input text will be tagged on the same line with a greyed out "stop".  Also, cues are provided while typing certain commands but it is not always clear what is required.

This demonstrates persistence:
$ redis-cli
127.0.0.1:6379> lrange friends 1-2<stop>
(error) ERR wrong number of arguments for 'lrange' command
127.0.0.1:6379> lrange friends 1 2

2) "Suzy"
127.0.0.1:6379> GET server:name
"pluto"
127.0.0.1:6379> set resource:lock "Demo 2"
OK
127.0.0.1:6379> expire "Demo 2" 10
(integer) 0

<later>

127.0.0.1:6379> ttl resource:lock
(integer) -1
127.0.0.1:6379> ttl resource:lock
(integer) -1

Lists are stacks or LIFO buffers:

127.0.0.1:6379> lpush friends "Lucy"
(integer) 7
127.0.0.1:6379> lrange friends 7 7
(empty list or set)
127.0.0.1:6379> lrange friends 0 0
1) "Lucy"
127.0.0.1:6379> lrange friends 0 -1
1) "Lucy"
2) "David"
3) "David"
4) "Suzy"
5) "Zack"
6) "Suzy"
7) "Zack"
127.0.0.1:6379> exit

This is just tinkering with the basics but should be enough.
