Redis 5.0.5 Install manual

Redis 5.0.5 安裝文檔(Install manual)

1、單實例安裝git

標題 內容
測試環境 Centos 7
虛擬機 vbox
redis版本 redis 5.0.5

1.編譯安裝redisredis

#使用wget從官網如今redis數據庫tar壓縮包
$ wget http://download.redis.io/releases/redis-5.0.5.tar.gz
#使用tar解壓tar壓縮包
$ tar xzf redis-5.0.5.tar.gz
#進入redis解壓後的目錄
$ cd redis-5.0.5
#使用make編譯安裝redis數據庫,直接make會報錯,詳細錯誤信息查看第5節錯誤分析內容
$ make MALLOC=libc

2.redis編譯測試shell

#直接make test報錯,須要安裝相關依賴包,運行測試時候須要tcl-Tool Command Language 包
$ yum install tcl
#執行make test 測試
$ make test

測試結果以下:
測試結果數據庫

3.運行redis數據庫服務器

運行完成編譯後,在源碼文件夾中的src文件夾中會生成redis相關的二進制文件。運行編譯好的二進制文件啓動redis數據庫:
The binaries that are now compiled are available in the src directory. Run Redis with:併發

#運行redis-server 二進制執行文件,啓動redis服務端程序。
$ src/redis-server

redis server啓動以下圖:
啓動dom

可使用redis-cli命令鏈接數據庫與數據庫服務端進行交互。
You can interact with Redis using the built-in client:socket

#運行redis-cli啓動數據庫客戶端,鏈接默認redis數據庫
$ src/redis-cli
#測試redis數據庫,插入一個foo bar 鍵值對
redis> set foo bar
#插入成功
OK
#獲取foo key的值
redis> get foo
"bar"

4.redis性能測試ide

redis 數據庫自帶性能測試工具,工具名稱:redis-benchmark,使用此工具對數據庫進行性能測試。函數

redis-benchmark具體使用參數
Invalid option "-help" or option argument missing

Usage: redis-benchmark [-h <host>] [-p <port>] [-c <clients>] [-n <requests>] [-k <boolean>]

 -h <hostname>      Server hostname (default 127.0.0.1)
 -p <port>          Server port (default 6379)
 -s <socket>        Server socket (overrides host and port)
 -a <password>      Password for Redis Auth
 -c <clients>       Number of parallel connections (default 50)
 -n <requests>      Total number of requests (default 100000)
 -d <size>          Data size of SET/GET value in bytes (default 3)
 --dbnum <db>       SELECT the specified db number (default 0)
 -k <boolean>       1=keep alive 0=reconnect (default 1)
 -r <keyspacelen>   Use random keys for SET/GET/INCR, random values for SADD
  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 <numreq>        Pipeline <numreq> requests. Default 1 (no pipeline).
 -e                 If server replies with errors, show them on stdout.
                    (no more than 1 error per second is displayed)
 -q                 Quiet. Just show query/sec values
 --csv              Output in CSV format
 -l                 Loop. Run the tests forever
 -t <tests>         Only run the comma separated list of tests. The test
                    names are the same as the ones produced as output.
 -I                 Idle mode. Just open N idle connections and wait.

Examples:

 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.

use redis-benchmark tools test redis performance .

使用redis-benchmark 測試redis性能
#實例同時執行 1000 個請求來檢測性能
./redis-benchmark -n 1000 -q

#測試存取大小爲100字節的數據包的性能
redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100

#100個併發鏈接,100000個請求,檢測host爲localhost 端口爲6379的redis服務器性能 
redis-benchmark -h 127.0.0.1 -p 6379 -c 100 -n 100000

5.錯誤記錄與分析

直接make報以下錯誤:
錯誤

緣由是jemalloc重載了Linux下的ANSI C的malloc和free函數。解決辦法:make時添加參數。

make MALLOC=libc

運行後編譯成功。以下圖:
編譯成功
