redis安裝及效能測試

Redis是一個開源的使用ANSI C語言編寫、遵守BSD協議、支援網路、可基於記憶體亦可持久化的日誌型、Key-Value資料庫。通常被稱為資料結構伺服器,因為值(value)可以是 字串(String), 雜湊(Hash), 列表(list), 集合(sets) 和 有序集合(sorted sets)等型別。

Linux安裝

1、選擇下載資源的檔案目錄(如:/opt),獲取redis資源

wget http://download.redis.io/releases/redis-4.0.8.tar.gz

2、解壓

tar xzvf redis-4.0.8.tar.gz

3、安裝

cdredis-2.8.17

make

cd src

make install PREFIX=/usr/local/redis (該處遇到失敗時,查詢了You need tcl 8.5 or newer in order to run the Redis test)

解決方案:

安裝tcl-8.5.13-8.el7.x86_64.rpm

1>wgethttp://mirror.centos.org/centos/7/os/x86_64/Packages/tcl-8.5.13-8.el7.x86_64.rpm

2>rpm -ivhtcl-8.5.13-8.el7.x86_64.rpm

4.移動配置檔案到安裝目錄下

  cd ../

  mkdir /usr/local/redis/etc

  mv redis.conf /usr/local/redis/etc

5.配置redis為後臺啟動

  vi /usr/local/redis/etc/redis.conf //將daemonize no改成daemonize yes

6.將redis加入到開機啟動

  vi /etc/rc.local //在裡面新增內容:/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf (意思就是開機呼叫這段開啟redis的命令)

7.開啟redis

  /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

常用命令  

  redis-server /usr/local/redis/etc/redis.conf //啟動redis

  pkill redis //停止redis

  解除安裝redis:

    rm -rf /usr/local/redis //刪除安裝目錄

    rm -rf /usr/bin/redis-* //刪除所有redis相關命令指令碼

    rm -rf /root/download/redis-4.0.4 //刪除redis解壓資料夾

redis效能測試

Redis 自帶了一個叫redis-benchmark的工具來模擬 N 個客戶端同時發出 M 個請求。 (類似於 Apache ab 程式)。你可以使用 redis-benchmark -h 來檢視基準引數

以下引數被支援:

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 2)
 -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).
 -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.
