二，apt方式安装redis6:

1,安装

root@lhdpc:~# apt-get install redis

2，检查安装完的效果：

root@lhdpc:~# whereis redis-server
redis-server: /usr/bin/redis-server /usr/share/man/man1/redis-server.1.gz

3，查看redis版本:

root@lhdpc:~# redis-server -v
Redis server v=6.0.15 sha=00000000:0 malloc=jemalloc-5.2.1 bits=64 build=4610f4c3acf7fb25

4,查看redis服务的状态:

root@lhdpc:~# systemctl status redis.service
● redis-server.service - Advanced key-value store
     Loaded: loaded (/lib/systemd/system/redis-server.service; enabled; vendor preset: enabled)
     Active: active (running) since Mon 2021-12-27 10:09:00 CST; 3min 45s ago
       Docs: http://redis.io/documentation,

可见已处于启动状态

 

5,查看redis绑定的端口:

root@lhdpc:~# ss -lntp | grep redis
LISTEN 0      511        127.0.0.1:6379       0.0.0.0:*    users:(("redis-server",pid=1790,fd=6))                                            
LISTEN 0      511            [::1]:6379          [::]:*    users:(("redis-server",pid=1790,fd=7)) 

三，测试安装效果

root@lhdpc:~# redis-cli
127.0.0.1:6379> get a
(nil)
127.0.0.1:6379> set a "this is a"
OK
127.0.0.1:6379> get a
"this is a"
127.0.0.1:6379>

四，查看linux的版本:
