简介:
简单来说，twemproxy是twitter开发的一个redis代理proxy。
通过Twemproxy可以使用多台服务器来水平扩张redis服务，可以有效的避免单点故障问题。
虽然使用Twemproxy需要更多的硬件资源和在redis性能有一定的损失（twitter测试约20%），
但是能够提高整个系统的HA也是相当划算的。
Twemproxy可以把数据sharding到多台服务器的上，每台服务器存储着整个数据集的一部分。
因而，当某一台redis服务器宕机了，那么也就失去了一部分数据。如果借助于redis的master-slave replication，
能保证在任何一台redis不能工作情况下，仍然能够保证能够存在一个整个数据集的完全覆盖，
那么整个redis group（或者称作cluster）仍然能够正常工作。
安装配置：
autoconf下载地址：http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz
twemproxy的安装要求autoconf的版本在2.64以上，否则提示”error: Autoconf version 2.64 or higher is required“。autoconf直接make和make install即可。
twemproxy下载地址：https://codeload.github.com/twitter/twemproxy/zip/master
下载完成后进入twemproxy-master目录

编译安装twemproxy
./configure --prefix=/export/Server/twemproxy
报错
configure: error: cannot find install-sh, install.sh, or shtool in config "."/config
方法：
automake --add-missing
再来：
./configure --prefix=/export/Server/twemproxy
报错
config.status: error: cannot find input file: `Makefile.in'
方法：
automake --add-missing
automake
再来：
./configure --prefix=/export/Server/twemproxy
成功
最后
make -j 8
make install
添加环境变量
echo "PATH=$PATH:/export/Server/twemproxy/sbin/" >> /etc/profile
source /etc/profile
新建配置文件
创建pid文件目录
cd /usr/local/twemproxy
mkdir run
创建proxy配置文件
mkdir sbin/conf
cd /sbin/conf
拷贝配置文件
cp /data/packages/twemproxy-master/conf/nutcracker.yml /usr/local/twemproxy/sbin/conf
然后根据需求修改配置文件
测试配置文件语法正确性
[root@redis-server sbin]# ./nutcracker -t
测试配置文件的时候报错
nutcracker: configuration file 'conf/nutcracker.yml' syntax is invalid
conf下面的nutcracker.yml文件必须放在twemproxy/sbin/目录下，否则报上面错误
再次测试
[root@redis-server sbin]# ./nutcracker -t
nutcracker: configuration file 'conf/nutcracker.yml' syntax is ok
启动
./nutcracker -d -c /export/Server/twemproxy/sbin/conf/nutcracker.yml -p /export/Server/twemproxy/run/redisproxy.pid -o /export/Server/twemproxy/run/redisproxy.log
查看日志
/export/Server/twemproxy/run/redisproxy.log
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:
Set测试：
通过twemproxy测试：
[root@redis-server src]#redis-benchmark -h 10.23.22.240 -p 22121 -c 100 -t set -d 100 -l –q
SET: 38167.94 requests per second
直接对后端redis测试：
[root@redis-server ~]#redis-benchmark -h 10.23.22.241 -p 6379 -c 100 -t set -d 100 -l –q
SET: 53191.49 requests per second
Get测试：
通过twemproxy测试：
[root@redis-server src]#redis-benchmark -h 10.23.22.240 -p 22121 -c 100 -t get -d 100 -l -q
GET: 37453.18 requests per second
直接对后端redis测试：
[root@redis-server ~]#redis-benchmark -h 10.23.22.241 -p 6379 -c 100 -t get -d 100 -l -q
GET: 62111.80 requests per second
查看键值分布：
[root@redis-server ~]#redis-cli info|grep db0
db0:keys=51483,expires=0,avg_ttl=0
[root@redis-server ~]#redis-cli info|grep db0
db0:keys=48525,expires=0,avg_ttl=0
测试结果:以基本的set get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。
