redis安装及性能测试

Redis是一个开源的使用ANSI C语言编写、遵守BSD协议、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库。通常被称为数据结构服务器,因为值(value)可以是 字符串(String), 哈希(Hash), 列表(list), 集合(sets) 和 有序集合(sorted sets)等类型。

Linux安装

1、选择下载资源的文件目录(如:/opt),获取redis资源

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

 2、解压

tar xzvf redis-4.0.8.tar.gz

3、安装

cd redis-2.8.17

make

cd src

make install PREFIX=/usr/local/redis (该处遇到失败时,查询了You need tcl 8.5 or newer in order to run the Redis test)

 解决方案:

安装tcl-8.5.13-8.el7.x86_64.rpm

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

2>rpm -ivh tcl-8.5.13-8.el7.x86_64.rpm

4.移动配置文件到安装目录下

  cd ../

  mkdir /usr/local/redis/etc

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

 5.配置redis为后台启动

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

6.将redis加入到开机启动

  vi /etc/rc.local //在里面添加内容:/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf (意思就是开机调用这段开启redis的命令)

7.开启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 //启动redis

  pkill redis  //停止redis

  卸载redis:

    rm -rf /usr/local/redis //删除安装目录

    rm -rf /usr/bin/redis-* //删除所有redis相关命令脚本

    rm -rf /root/download/redis-4.0.4 //删除redis解压文件夹

redis性能测试

 Redis 自带了一个叫 redis-benchmark 的工具来模拟 N 个客户端同时发出 M 个请求。 (类似于 Apache ab 程序)。你可以使用 redis-benchmark -h 来查看基准参数

以下参数被支持:

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.
