环境说明:
twemproxy | 192.168.0.112:22122 | centos6.5 |
redis | 192.168.0.113:6379 | centos6.5 |
redis | 192.168.0.113:6380 | centos6.5 |
twemproxy安装:
[[email protected] src]# tar -zxf nutcracker-0.4.0.tar.gz [[email protected] src]# cd nutcracker-0.4.0 [[email protected] nutcracker-0.4.0]# ./configure --prefix=/usr/local/nutcracker/ [[email protected] nutcracker-0.4.0]# make && make install [[email protected] nutcracker-0.4.0]# cp -r conf scripts /usr/local/nutcracker/
配置环境变量:
[[email protected] nutcracker-0.4.0]# cd /etc/profile.d/ [[email protected] profile.d]# vim twemproxy.sh #!/bin/sh #set Rutcracker environment export RUTCRACKER_HOME=/opt/phpdba/nutcracker-0.2.4 export PATH=$RUTCRACKER_HOME/bin:$PATH source twemporxy.sh
修改nutcracker配置文件:
[[email protected] nutcracker-0.4.0]# cd /usr/local/nutcracker/ [[email protected] nutcracker]# vim conf/nutcracker.yml alpha: listen: 0.0.0.0:22121 hash: fnv1a_64 distribution: ketama auto_eject_hosts: true #将出现故障的redis从集群中移除 redis: true server_retry_timeout: 2000 server_failure_limit: 1 servers: - 192.168.0.112:6379:1 server1 - 192.168.0.113:6379:1 server2 - 192.168.0.113:6380:1 server3
检查配置文件语法
[[email protected] nutcracker]# nutcracker -c conf/nutcracker.yml -t nutcracker: configuration file ‘/opt/phpdba/nutcracker-0.2.4/conf/nutcracker.yml‘ syntax is ok
启动:
[[email protected] nutcracker]# nutcracker -d -c /opt/phpdba/nutcracker-0.2.4/conf/nutcracker.yml
性能测试
这里使用redis自带的redis-benchmark进行简单的性能测试,测试结果如下:
1.测试:
a.通过twemproxy测试:
[[email protected] nutcracker]# redis-benchmark -h 127.0.0.1 -q -t set,get,incr,lpush,lpop,sadd,spop,lpush,lrange -c 100 -p 22121 SET: 62972.29 requests per second GET: 87336.24 requests per second INCR: 85034.02 requests per second LPUSH: 81699.35 requests per second LPOP: 82987.55 requests per second SADD: 85034.02 requests per second SPOP: 87412.59 requests per second LPUSH (needed to benchmark LRANGE): 80840.74 requests per second LRANGE_100 (first 100 elements): 28384.90 requests per second LRANGE_300 (first 300 elements): 9022.01 requests per second LRANGE_500 (first 450 elements): 4810.00 requests per second LRANGE_600 (first 600 elements): 3363.04 requests per second
b.通过对后端redis查看:
[[email protected] nutcracker]# redis-cli 127.0.0.1:6379> KEYS * 1) "counter:__rand_int__" 127.0.0.1:6379> [[email protected] nutcracker]# redis-cli 127.0.0.1:6379> KEYS * 1) "mylist" 2) "key:__rand_int__"
发现我们的测试数据分片到了两个redis实例中。
2.查看键值分布(分别在集群后端的redis实例查看)
[[email protected] nutcracker]# redis-cli info|grep db0 db0:keys=1,expires=0,avg_ttl=0 [[email protected] nutcracker]# redis-cli info|grep db0 db0:keys=1,expires=0,avg_ttl=0 [[email protected] nutcracker]# redis-cli info|grep db0 db0:keys=2,expires=0,avg_ttl=0
测试结果:以基本的命令通过twemproxy性能有所下降;通过twemproxy分布基本平均。测试数据以业务测试为准。
