1,查看基准测试工具的用法
[root@langfang src]# pwd
/redis_dir/redis-4.0.9/src
[root@langfang src]# ./redis-benchmark  -help
Invalid option "-help" or option argument missing


Usage: redis-benchmark [-h ] [-p ] [-c ] [-n ] [-k ]


 -h      Server hostname (default 127.0.0.1) -h 连接REDIS服务器IP，默认为127.0.0.1
 -p          Server port (default 6379)    -P REDIS服务器端口 ，默认为6379
 -s        Server socket (overrides host and port)  -S 服务器套接字（覆盖主机和端口）
 -a      Password for Redis Auth --A REDIS AUTH的认证密码
 -c       Number of parallel connections (default 50)  --c 表示并发连接数量，默认50个
 -n      Total number of requests (default 100000)  ---n 请求的总数量，默认为100000，即10万
 -d          Data size of SET/GET value in bytes (default 3) --D 表示SET GET的大小，默认大小为3
 --dbnum       SELECT the specified db number (default 0)  --dbnum 指定连接哪个数据库，默认为0号数据库
 -k       1=keep alive 0=reconnect (default 1)  -k 布尔类型，1为保持连接，默认值；0为重连
 -r   Use random keys for SET/GET/INCR, random values for SADD --r 为SET GET INCR操作使用随机的键，为SADD使用随机值
  Using this option the benchmark will expand the string __rand_int__
  inside an argument with a 12 digits number in the specified range
  from 0 to keyspacelen-1. The substitution changes every time a command
  is executed. Default tests use this to hit random keys in the
  specified range.
 -P        Pipeline requests. Default 1 (no pipeline).  --P 与管道技术有关，请求的次数，默认为1，即禁用管道技术，假如服务器报错，显示报错信息
 -e                 If server replies with errors, show them on stdout.  
                    (no more than 1 error per second is displayed) --仅仅每秒显示1个报错
 -q                 Quiet. Just show query/sec values  -Q 安静，仅仅显示 每秒 查询值
 --csv              Output in CSV format --CSV 以CSV格式输出
 -l                 Loop. Run the tests forever -L 一直压测，不停止
 -t         Only run the comma separated list of tests. The test -T   -L 运行以 逗 号分隔的测试列表，指定具体的压力测试场景，比如是set or mget or get and so on
                    names are the same as the ones produced as output.
 -I                 Idle mode. Just open N idle connections and wait. --L 空闲模式，只是打开N个空闲连接然后等待


Examples: ---示例


 Run the benchmark with the default configuration against 127.0.0.1:6379:
   $ redis-benchmark


 Use 20 parallel clients, for a total of 100k requests, against 192.168.1.1:
   $ redis-benchmark -h 192.168.1.1 -p 6379 -n 100000 -c 20


 Fill 127.0.0.1:6379 with about 1 million keys only using the SET test:
   $ redis-benchmark -t set -n 1000000 -r 100000000


 Benchmark 127.0.0.1:6379 for a few commands producing CSV output:
   $ redis-benchmark -t ping,set,get -n 100000 --csv


 Benchmark a specific command line:
   $ redis-benchmark -r 10000 -n 10000 eval 'return redis.call("ping")' 0


 Fill a list with 10000 random elements:
   $ redis-benchmark -r 10000 -n 10000 lpush mylist __rand_int__


 On user specified command lines __rand_int__ is replaced with a random integer
 with a range of values selected by the -r option.

[root@langfang src]# 




3，还是各种压测场景，不过是20个并发，10万次请求，连接指定REDIS服务器
[root@langfang src]# ./redis-benchmark -h 127.0.0.1 -p 6379 -n 100000 -c 20
====== PING_INLINE ======

4，指定测试场景比如 GET AND SET 以及随机键的数量以及请求个数
[root@langfang src]# ./redis-benchmark  -t set,get -n 100000 -r 1000
====== SET ======
  100000 requests completed in 1.60 seconds
  50 parallel clients

  keep alive: 1


93.91% <= 1 milliseconds
99.93% <= 2 milliseconds
100.00% <= 2 milliseconds
59488.40 requests per second




5，csv格式输出
[root@langfang src]# ./redis-benchmark -t ping,get,set -n 1000 --csv
"PING_INLINE","52631.58"
"PING_BULK","55555.56"
"SET","52631.58"
"GET","52631.58"


6，运行特定的命令行
[root@langfang src]# ./redis-benchmark  -r 1000 -n 100000 eval 'return redis.call("ping")'
====== eval return redis.call("ping") ======
  100000 requests completed in 1.56 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1


95.66% <= 1 milliseconds
99.93% <= 2 milliseconds
100.00% <= 2 milliseconds
63979.53 requests per second




7， Fill a list with 10000 random elements  以随机指定的范围元素填充list
[root@langfang src]# ./redis-benchmark  -r 10000 -n 1000 lpush mylist _rand_init__
====== lpush mylist _rand_init__ ======
  1000 requests completed in 0.02 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1


87.20% <= 1 milliseconds
99.50% <= 2 milliseconds
100.00% <= 2 milliseconds
47619.05 requests per second




[root@langfang src]# ./redis-benchmark  -r 10000 -n 1000 set mylist _rand_init__
====== set mylist _rand_init__ ======
  1000 requests completed in 0.02 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1


86.40% <= 1 milliseconds
100.00% <= 1 milliseconds
47619.05 requests per second




8,静默方式压力测试
[root@langfang src]# ./redis-benchmark  -t set,get -n 100000 -r 1000
====== SET ======
  100000 requests completed in 1.58 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1


94.99% <= 1 milliseconds
99.96% <= 2 milliseconds
100.00% <= 2 milliseconds
63211.12 requests per second


====== GET ======
  100000 requests completed in 1.60 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1


95.21% <= 1 milliseconds
99.99% <= 2 milliseconds
100.00% <= 2 milliseconds
62617.41 requests per second


--可见静默方式只显示每次处理的请求数以及压力测试场景
[root@langfang src]# ./redis-benchmark  -t set,get -n 100000 -r 1000 -q
SET: 63091.48 requests per second
GET: 64724.92 requests per second




9，redis-cli可以直接附上操作命令
[root@langfang src]# ./redis-cli flushall
OK
[root@langfang src]# ./redis-cli dbsize
(integer) 0
[root@langfang src]# 




10，--r表示产生的随机键的数量，数量大可以模拟 键不命中情况
[root@langfang src]# ./redis-cli dbsize
(integer) 0
[root@langfang src]# ./redis-benchmark  -t set -r 8888 -n 100000
====== SET ======
  100000 requests completed in 1.61 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1


94.16% <= 1 milliseconds
99.93% <= 2 milliseconds
99.95% <= 3 milliseconds
100.00% <= 3 milliseconds
62305.30 requests per second




[root@langfang src]# ./redis-cli dbsize
(integer) 8888
[root@langfang src]# 




11，默认情况是处理1个请求然后顺序接着处理下1个请求，但可以通过-P 管道技术，并发处理多个请求，下述效果非常明显，成9倍左右的差异
（同时处理多条命令需要PIPELINE管道技术）


[root@langfang src]# ./redis-benchmark -t get,set -n 100000 -q
SET: 64516.13 requests per second
GET: 64516.13 requests per second






[root@langfang src]# ./redis-benchmark -t get,set -n 100000 -P 16 -q
SET: 452488.69 requests per second
GET: 529100.56 requests per second
