备注:测试版本 redis 4.0.9

一.redis连接数

查看redis的连接数，redis的默认连接数是1w，当然也可以通过配置文件来修改

10.31.1.124:6379> config get maxclients
1) "maxclients"
2) "10000"

二.redis连接相关命令

1.1 client list

client list 列出连接到redis服务的客户端列表

10.31.1.124:6379> client list
id=5 addr=10.31.1.123:60814 fd=7 name= age=36 idle=36 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=0 obl=0 oll=0 omem=0 events=r cmd=command
id=6 addr=10.31.1.124:37302 fd=8 name= age=30 idle=0 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=client
10.31.1.124:6379> 

1.2 client setname 和 client getname

设置和获取当前连接的名字，感觉这个用处不是很大

10.31.1.124:6379> client setname redis1
OK
10.31.1.124:6379> client getname
"redis1"

1.3 client pause

client pause 10000
挂起客户端，单位毫秒，此处是挂起10秒
当某个客户端的请求太频繁，可以挂起一段时间，降低服务器的负载

10.31.1.124:6379> client pause 10000
OK
10.31.1.124:6379> 
10.31.1.124:6379> 
10.31.1.124:6379> 
-- 等待了接近5秒才
10.31.1.124:6379> client getname
"redis1"
(4.56s)
10.31.1.124:6379> 
10.31.1.124:6379> client getname
"redis1"

1.4 client kill

关闭客户端连接

10.31.1.124:6379> client list
id=5 addr=10.31.1.123:60814 fd=7 name= age=36 idle=36 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=0 obl=0 oll=0 omem=0 events=r cmd=command
id=6 addr=10.31.1.124:37302 fd=8 name= age=30 idle=0 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=client
10.31.1.124:6379> 
10.31.1.124:6379> client kill 10.31.1.123:60814
OK
10.31.1.124:6379> client list
id=6 addr=10.31.1.124:37302 fd=8 name=redis1 age=247 idle=0 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=client
10.31.1.124:6379>
