1、安装redis
首页地址：http://redis.io/
下载地址：http://download.redis.io/ 下载最新的源码包
wget http://download.redis.io/releases/redis-2.6.16.tar.gz tar -zxvf redis-stable.tar.gz -C /usr/local/ cd /usr/local/redis-stable/ make MALLOC=libc make install
2、运行
加载配置文件并后台运行
redis-server /usr/local/redis-stable/redis.conf &
#redis-cli （命令行工具）
3、测试
# redis-benchmark --help 获取帮助信息，其中包含压力测试命令样例
实际测试举例
[root@localhost~]# redis-benchmark -t set -c 20 -n 1000000 -r 100000000 ====== SET ====== 1000000 requests completed in 8.92 seconds 20 parallel clients 3 bytes payload keep alive: 1 100.00% <= 0 milliseconds 112095.06 requests per second
4、主从配置及测试:
| 主 | 10.10.10.34 | gc-redis1 | 6379 |
| 从 | 10.10.10.35 | gc-redis2 | 6379 |
| 从 | 10.10.10.36 | gc-redis3 | 6379 |
#主服务器(10.34)上做如下配置，其他默认即可：
[root@gc-redis1 redis-stable]# vim /usr/local/redis-stable/redis.conf masterauth "redispass" requirepass "redispass"
#从服务器上(10.35,10.36)做如下配置，其他默认即可：
[root@gc-redis2 redis-stable]# vim /usr/local/redis-stable/redis.conf slaveof 10.10.10.34 6379 masterauth "redispass" requirepass "redispass"
#启动主、从redis服务：
redis-server /usr/local/redis-stable/redis.conf &
