簡(jiǎn)介:

創(chuàng)新互聯(lián)專業(yè)為企業(yè)提供大箐山網(wǎng)站建設(shè)、大箐山做網(wǎng)站、大箐山網(wǎng)站設(shè)計(jì)、大箐山網(wǎng)站制作等企業(yè)網(wǎng)站建設(shè)、網(wǎng)頁(yè)設(shè)計(jì)與制作、大箐山企業(yè)網(wǎng)站模板建站服務(wù)，10余年大箐山做網(wǎng)站經(jīng)驗(yàn)，不只是建網(wǎng)站，更提供有價(jià)值的思路和整體網(wǎng)絡(luò)服務(wù)。

簡(jiǎn)單來(lái)說(shuō)，twemproxy是twitter開(kāi)發(fā)的一個(gè)redis代理proxy。

通過(guò)Twemproxy可以使用多臺(tái)服務(wù)器來(lái)水平擴(kuò)張redis服務(wù)，可以有效的避免單點(diǎn)故障問(wèn)題。

雖然使用Twemproxy需要更多的硬件資源和在redis性能有一定的損失（twitter測(cè)試約20%），

但是能夠提高整個(gè)系統(tǒng)的HA也是相當(dāng)劃算的。

Twemproxy可以把數(shù)據(jù)sharding到多臺(tái)服務(wù)器的上，每臺(tái)服務(wù)器存儲(chǔ)著整個(gè)數(shù)據(jù)集的一部分。

因而，當(dāng)某一臺(tái)redis服務(wù)器宕機(jī)了，那么也就失去了一部分?jǐn)?shù)據(jù)。如果借助于redis的master-slave replication，

能保證在任何一臺(tái)redis不能工作情況下，仍然能夠保證能夠存在一個(gè)整個(gè)數(shù)據(jù)集的完全覆蓋，

那么整個(gè)redis  group（或者稱作cluster）仍然能夠正常工作。

安裝配置：

autoconf下載地址：http://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz

twemproxy的安裝要求autoconf的版本在2.64以上，否則提示”error: Autoconf version 2.64 or higher is required“。autoconf直接make和make install即可。

編譯安裝twemproxy

./configure --prefix=/export/Server/twemproxy

報(bào)錯(cuò)

configure: error: cannot find install-sh, install.sh, or shtool in config "."/config

方法：

automake --add-missing

再來(lái)：

./configure --prefix=/export/Server/twemproxy

報(bào)錯(cuò)

config.status: error: cannot find input file: `Makefile.in'

方法：

automake --add-missing

automake

再來(lái)：

./configure --prefix=/export/Server/twemproxy

成功

最后

make -j 8

make install

添加環(huán)境變量

echo "PATH=$PATH:/export/Server/twemproxy/sbin/" >> /etc/profile

新建配置文件

創(chuàng)建pid文件目錄

cd /usr/local/twemproxy

mkdir run

創(chuàng)建proxy配置文件

mkdir sbin/conf

cd /sbin/conf

拷貝配置文件

cp /data/packages/twemproxy-master/conf/nutcracker.yml /usr/local/twemproxy/sbin/conf

然后根據(jù)需求修改配置文件

測(cè)試配置文件語(yǔ)法正確性

[root@redis-server sbin]# ./nutcracker -t

測(cè)試配置文件的時(shí)候報(bào)錯(cuò)

nutcracker: configuration file 'conf/nutcracker.yml' syntax is invalid

conf下面的nutcracker.yml文件必須放在twemproxy/sbin/目錄下，否則報(bào)上面錯(cuò)誤

再次測(cè)試

[root@redis-server sbin]# ./nutcracker -t

nutcracker: configuration file 'conf/nutcracker.yml' syntax is ok

啟動(dòng)

./nutcracker -d -c /export/Server/twemproxy/sbin/conf/nutcracker.yml -p /export/Server/twemproxy/run/redisproxy.pid -o /export/Server/twemproxy/run/redisproxy.log

性能測(cè)試

這里使用redis自帶的redis-benchmark進(jìn)行簡(jiǎn)單的性能測(cè)試，測(cè)試結(jié)果如下:

Set測(cè)試：

通過(guò)twemproxy測(cè)試：

[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

直接對(duì)后端redis測(cè)試：

[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測(cè)試：

通過(guò)twemproxy測(cè)試：

[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

直接對(duì)后端redis測(cè)試：

[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

查看鍵值分布：

[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

測(cè)試結(jié)果:以基本的set get命令通過(guò)twemproxy性能有所下降;通過(guò)twemproxy分布基本平均。測(cè)試數(shù)據(jù)以業(yè)務(wù)測(cè)試為準(zhǔn)。
