Redis 集群是一個提供在多個Redis間節點間共享數據的程序集.redis3.0以前，只支持主從同步的，如果主的掛了，寫入就成問題了。3.0出來后就可以很好幫我們解決這個問題。

目前redis 3.0還不穩定，如果要用在生產環境中，要慎重。

?

一，redis服務器說明

192.168.10.219 6379?

192.168.10.219 6380?

192.168.10.219 6381?

?

192.168.10.220 6382?

192.168.10.220 6383?

192.168.10.220 6384?

192.168.10.219 6379 192.168.10.219 6380 192.168.10.219 6381192.168.10.220 6382 192.168.10.220 6383 192.168.10.220 6384

要讓集群正常運作至少需要三個主節點，不過在剛開始試用集群功能時， 強烈建議使用六個節點： 其中三個為主節點， 而其余三個則是各個主節點的從節點。所有用二臺機器，開6個redis進程，模擬6臺機器。

二，安裝ruby,rubygems

查看復制打印?

# yum -y install gcc openssl-devel libyaml-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel gcc-c++ automake autoconf?

?

# yum -y install ruby rubygems?? //安裝ruby rubygems?

?

//換源?

# gem source -l?

# gem source --remove http://rubygems.org/?

# gem sources -a http://ruby.taobao.org/?

# gem source -l?

?

# gem install redis --version 3.0.0? //安裝gem_redis?

以前寫過一篇ruby on rails的文章，請參考：centos ruby on rails apache mysql 安裝配置詳解

喜歡手動編譯的人，可以參考這篇文章，安裝ruby.

三，安裝redis3.0.0

?

1，安裝redis

查看復制打印?

# wget http://download.redis.io/releases/redis-3.0.0.tar.gz?

# tar -xvzf redis-3.0.0.tar.gz?

# cd redis-3.0.0?

# make && make install?

# cd src?

# cp redis-trib.rb /usr/local/bin???

?

# mkdir /etc/redis?

# mkdir /var/log/redis?

# wget http://download.redis.io/releases/redis-3.0.0.tar.gz # tar -xvzf redis-3.0.0.tar.gz # cd redis-3.0.0 # make && make install # cd src # cp redis-trib.rb /usr/local/bin # mkdir /etc/redis # mkdir /var/log/redis

上述操作要先在二臺機器上面都操作好。

2,配置redis

查看復制打印?

[root@slave2 redis-3.0.0]#? vim redis.conf?? //解壓的根目錄，有redis.conf,做以下修改?

port 6379?

pidfile /var/run/redis-6379.pid?

dbfilename dump-6379.rdb?

appendfilename "appendonly-6379.aof"?

cluster-config-file nodes-6379.conf?

cluster-enabled yes?

cluster-node-timeout 5000?

appendonly yes?

[root@slave2 redis-3.0.0]# vim redis.conf //解壓的根目錄，有redis.conf,做以下修改 port 6379 pidfile /var/run/redis-6379.pid dbfilename dump-6379.rdb appendfilename "appendonly-6379.aof" cluster-config-file nodes-6379.conf cluster-enabled yes cluster-node-timeout 5000 appendonly yes

3，copy配置文件，并修改端口

查看復制打印?

# cp redis.conf /etc/redis/redis-6379.conf?

# cp redis.conf /etc/redis/redis-6380.conf?

# cp redis.conf /etc/redis/redis-6381.conf?

?

# scp redis.conf 192.168.10.220:/etc/redis/redis-6382.conf?

# scp redis.conf 192.168.10.220:/etc/redis/redis-6383.conf?

# scp redis.conf 192.168.10.220:/etc/redis/redis-6384.conf?

?

# sed -i "s/6379/6380/g" /etc/redis/redis-6380.conf?

# sed -i "s/6379/6381/g" /etc/redis/redis-6381.conf?

?

# sed -i "s/6379/6382/g" /etc/redis/redis-6382.conf?

# sed -i "s/6379/6383/g" /etc/redis/redis-6383.conf?

# sed -i "s/6379/6384/g" /etc/redis/redis-6384.conf?

# cp redis.conf /etc/redis/redis-6379.conf # cp redis.conf /etc/redis/redis-6380.conf # cp redis.conf /etc/redis/redis-6381.conf# scp redis.conf 192.168.10.220:/etc/redis/redis-6382.conf # scp redis.conf 192.168.10.220:/etc/redis/redis-6383.conf # scp redis.conf 192.168.10.220:/etc/redis/redis-6384.conf# sed -i "s/6379/6380/g" /etc/redis/redis-6380.conf # sed -i "s/6379/6381/g" /etc/redis/redis-6381.conf# sed -i "s/6379/6382/g" /etc/redis/redis-6382.conf # sed -i "s/6379/6383/g" /etc/redis/redis-6383.conf # sed -i "s/6379/6384/g" /etc/redis/redis-6384.conf

將配置文件分別copy到二臺機器上，并替換端口：

查看復制打印?

# cat redis-6380.conf |awk '{if($0 !~ /^$/ && $0 !~ /#/) {print $0}}' |grep 6380?

pidfile /var/run/redis-6380.pid?

port 6380?

dbfilename dump-6380.rdb?

appendfilename "appendonly-6380.aof"?

cluster-config-file nodes-6380.conf?

# cat redis-6380.conf |awk '{if($0 !~ /^$/ && $0 !~ /#/) {print $0}}' |grep 6380 pidfile /var/run/redis-6380.pid port 6380 dbfilename dump-6380.rdb appendfilename "appendonly-6380.aof" cluster-config-file nodes-6380.conf

有5處修改端口的地方

4，啟動并查看redis

查看復制打印?

# redis-server /etc/redis/redis-6379.conf > /var/log/redis/redis-6379.log 2>&1 &?

# redis-server /etc/redis/redis-6380.conf > /var/log/redis/redis-6380.log 2>&1 &?

# redis-server /etc/redis/redis-6381.conf > /var/log/redis/redis-6381.log 2>&1 &?

?

# redis-server /etc/redis/redis-6382.conf > /var/log/redis/redis-6382.log 2>&1 &?

# redis-server /etc/redis/redis-6383.conf > /var/log/redis/redis-6383.log 2>&1 &?

# redis-server /etc/redis/redis-6384.conf > /var/log/redis/redis-6384.log 2>&1 &?

?

# netstat -tpnl |grep redis?

所有節點都啟動成功，并不代表，他們就是集群了。

四，創建集群，并查看

?

1，創建redis集群

# redis-trib.rb create --replicas 1 192.168.10.219:6379 192.168.10.219:6380 192.168.10.219:6381 192.168.10.220:6382 192.168.10.220:6383 192.168.10.220:6384?

# redis-trib.rb create --replicas 1 192.168.10.219:6379 192.168.10.219:6380 192.168.10.219:6381 192.168.10.220:6382 192.168.10.220:6383 192.168.10.220:6384

2，查看redis集群狀態

查看復制打印?

到這兒，redis集群就配置成功了

五，測試redis集群
