Redis集群的伪分布式搭建
Redis集群中至少应该有三个节点。要保证集群的高可用，需要每个节点有一个备份机。
1、使用ruby脚本搭建集群。需要ruby的运行环境
1 2 3 安装ruby um install ruby um install rubygems
2、安装ruby脚本运行使用的包。
1 2 3 4 5 6 7 8 9 [root@localhost ~]# gem install redis-3.0.0.gem uccessfully installed redis-3.0.0 gem installed nstalling ri documentation for redis-3.0.0... nstalling RDoc documentation for redis-3.0.0... root@localhost ~]# root@localhost ~]# cd redis-3.0.0/src root@localhost src]# ll *.rb rwxrwxr-x. 1 root root 48141 Apr 1 2015 redis-trib.rb
3、修改redis.conf配置文件。配置文件中还需要把cluster-enabled yes前的注释去掉。
4、创建集群实例文件夹
1 [root@localhost redis]# mkdir ../redis-cluster
5、拷贝redis到集群文件夹创建实例redis01
1 2 3 [root@localhost local]# cp redis/bin redis-cluster/redis01 -r cp: omitting directory `redis/bin'
6、删除appendonly.aof,dump.rdb
1 2 [root@localhost redis01]# rm -f appendonly.aof [root@localhost redis01]# rm -f dump.rdb
7、更改端口为7001和cluster-enabled yes前的注释去掉
8、复制redis01到集群文件夹创建其余实例,更改端口
1 2 3 4 5 [root@localhost redis-cluster]# cp -r redis01/ redis02 [root@localhost redis-cluster]# cp -r redis01/ redis03 [root@localhost redis-cluster]# cp -r redis01/ redis04 [root@localhost redis-cluster]# cp -r redis01/ redis05 [root@localhost redis-cluster]# cp -r redis01/ redis06
9、编写启动批处理shell文件start-all.sh
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 cd redis01 ./redis-server redis.conf cd .. cd redis02 ./redis-server redis.conf cd .. cd redis03 ./redis-server redis.conf cd .. cd redis04 ./redis-server redis.conf cd .. cd redis05 ./redis-server redis.conf cd .. cd redis06 ./redis-server redis.conf
10、赋予权限
1 [root@localhost redis-cluster]# chmod u+x start-all.sh
11、启动
1 2 3 4 5 6 7 8 9 10 11 [root@localhost redis-cluster]# ./start-all.sh [root@localhost redis-cluster]# ps aux|grep redis root 5893 0.0 0.3 33936 1696 ? Ssl 21:04 0:07 ./redis-server *:6379 root 6385 0.0 0.3 33936 1960 ? Ssl 23:36 0:00 ./redis-server *:7001 [cluster] root 6387 0.0 0.3 33936 1960 ? Ssl 23:36 0:00 ./redis-server *:7002 [cluster] root 6391 0.1 0.3 33936 1960 ? Ssl 23:36 0:00 ./redis-server *:7003 [cluster] root 6395 0.1 0.3 33936 1960 ? Ssl 23:36 0:00 ./redis-server *:7004 [cluster] root 6401 0.0 0.3 33936 1960 ? Ssl 23:36 0:00 ./redis-server *:7005 [cluster] root 6403 0.1 0.3 33936 1960 ? Ssl 23:36 0:00 ./redis-server *:7006 [cluster] root 6411 0.0 0.1 4356 732 pts/1 S+ 23:37 0:00 grep redis
12、复制redis下的src目录中的redis-trib.rb到集群
1 2 3 4 root@localhost redis-3.0.0]# cd src [root@localhost src]# ll *.rb -rwxrwxr-x. 1 root root 48141 Apr 1 2015 redis-trib.rb [root@localhost src]# cp redis-trib.rb /usr/local/redis-cluster/
13、使用ruby脚本搭建集群。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 [root@localhost redis-cluster]# ./redis-trib.rb create --replicas 1 192.168.25.153:7001 192.168.25.153:7002 192.168.25.153:7003 192.168.25.153:7004 192.168.25.153:7005 192.168.25.153:7006 >>> Creating cluster necting to node 192.168.25.153:7001: OK necting to node 192.168.25.153:7002: OK necting to node 192.168.25.153:7003: OK necting to node 192.168.25.153:7004: OK necting to node 192.168.25.153:7005: OK necting to node 192.168.25.153:7006: OK >>> Performing hash slots allocation on 6 nodes... ng 3 masters: 192.168.25.153:7001 192.168.25.153:7002 192.168.25.153:7003 ing replica 192.168.25.153:7004 to 192.168.25.153:7001 ing replica 192.168.25.153:7005 to 192.168.25.153:7002 ing replica 192.168.25.153:7006 to 192.168.25.153:7003 2e48ae301e9c32b04a7d4d92e15e98e78de8c1f3 192.168.25.153:7001 lots:0-5460 (5461 slots) master 8cd93a9a943b4ef851af6a03edd699a6061ace01 192.168.25.153:7002 lots:5461-10922 (5462 slots) master 2935007902d83f20b1253d7f43dae32aab9744e6 192.168.25.153:7003 lots:10923-16383 (5461 slots) master 74f9d9706f848471583929fc8bbde3c8e99e211b 192.168.25.153:7004 eplicates 2e48ae301e9c32b04a7d4d92e15e98e78de8c1f3 42cc9e25ebb19dda92591364c1df4b3a518b795b 192.168.25.153:7005 eplicates 8cd93a9a943b4ef851af6a03edd699a6061ace01 8b1b11d509d29659c2831e7a9f6469c060dfcd39 192.168.25.153:7006 eplicates 2935007902d83f20b1253d7f43dae32aab9744e6 I set the above configuration?

14、启动每个redis实例。
1 ./redis-trib.rb create --replicas 1 192.168.25.153:7001 192.168.25.153:7002 192.168.25.153:7003 192.168.25.153:7004 192.168.25.153:7005 192.168.25.153:7006
15、创建关闭集群的脚本。
1 2 3 4 5 6 7 8 [root@localhost redis-cluster]# vim shutdow-all.sh edis01/redis-cli -p 7001 shutdown edis01/redis-cli -p 7002 shutdown edis01/redis-cli -p 7003 shutdown edis01/redis-cli -p 7004 shutdown edis01/redis-cli -p 7005 shutdown edis01/redis-cli -p 7006 shutdown root@localhost redis-cluster]# chmod u+x shutdow-all.sh
16、 集群的使用方法,Redis-cli连接集群
1 [root@localhost redis-cluster]# redis01/redis-cli -p 7002 -c
-c：代表连接的是redis集群
