redis 3.0.2 集羣搭建

1、環境

　　ubuntu 14.04 LTS、 redis 3.0.2

2、redis cluster 搭建 （單機測試）

　　一、redis的安裝

wget http://download.redis.io/releases/redis-3.0.2.tar.gz
tar zxvf redis-3.0.2.tar.gz cd redis-3.0.2/
make
make install

　　二、安裝ruby

sudo apt-get install ruby sudo gem install redis  #ruby的redis驅動

　  三、在單機測試的話，咱們用redis-server分別啓動多個文件就能夠了，我這裏採用的是6個端口，在redis cluster 裏是三主、三從…. 當時也能夠按照本身的狀況設立主從….  須要注意的是redis.conf要開發cluster的選項。  我簡單寫了一個批量修改redis.conf的腳本.

for i in `seq -w 0 5`;do
    cp redis.conf 700$i.conf sed -i "s/6379/700$i/g" 700$i.conf sed -i 's/daemonize no/daemonize yes/g' 700$i.conf sed -i 's/# cluster-enabled yes/cluster-enabled yes/g' 700$i.conf sed -i 's/# cluster-node-timeout 15000/cluster-node-timeout 15000/g' 700$i.conf sed -i "s/# cluster-config-file nodes-700*/cluster-config-file nodes-700$i.conf/g" 700$i.conf redis-server 700$i.conf done

　　四、檢測進程

root@Gangli:/etc/redis$ ps aux | grep redis root 8913  0.1  1.0  38508 10948 ?        Ssl  10:27   0:02 redis-server *:7000 [cluster] root 8923  0.1  1.0  38508 10972 ?        Ssl  10:27   0:02 redis-server *:7001 [cluster] root 8933  0.1  1.0  38508 11016 ?        Ssl  10:27   0:02 redis-server *:7002 [cluster] root 8943  0.1  0.8  38508  8868 ?        Ssl  10:27   0:02 redis-server *:7003 [cluster] root 8953  0.1  0.9  38508  9196 ?        Ssl  10:27   0:02 redis-server *:7004 [cluster] root 8963  0.1  0.8  38508  8972 ?        Ssl  10:27   0:02 redis-server *:7005 [cluster]

　　五、用redis-trib.rb來建立redis cluster集羣，下面是成功的提示。

root@Gangli:/tmp/soft/redis-3.0.2/src# ./redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005

 　　六、開啓集羣模式

root@Gangli:/tmp/soft/redis-3.0.2/src# redis-cli -c -p 7001 -h 127.0.0.1
