Redis集群安装

检查环境：

Ruby

[hadoop@hadoop01 ~]$ ruby -v

ruby 1.8.7 (2013-06-27 patchlevel 374) [x86_64-linux]

zlib

[hadoop@hadoop01 ~]$ rpm -qa |grep zlib

zlib-1.2.3-29.el6.x86_64

rubygems

[hadoop@hadoop01 ~]$ rpm -qa |grep rubygems

rubygems-1.3.7-5.el6.noarch

gcc

[hadoop@hadoop01 ~]$ rpm -qa |grep gcc

libgcc-4.4.7-11.el6.x86_64

gcc-4.4.7-11.el6.x86_64

[hadoop@hadoop01 ~]$ sudo gem install redis --version 3.0.0
Successfully installed redis-3.0.0
1 gem installed

解压编译Redis

解压：

[root@hadoop01 redis]# tar zxvf redis-3.0.1.tar.gz

make install

[root@hadoop01 redis]# cd redis-3.0.1

[root@hadoop01 redis-3.0.1]#  make install

运行、测试

[hadoop@hadoop01 bin]$ redis-server /usr/lib/redis/redis-3.0.1/redis.conf

[hadoop@hadoop01 ~]$ redis-cli

127.0.0.1:6379> set name gsw

OK

127.0.0.1:6379> get name

"gsw"

127.0.0.1:6379> set age 16

OK

127.0.0.1:6379> get age

"16"

127.0.0.1:6379> set age 17

OK

127.0.0.1:6379> get age

"17"

分布式集群安装

$ mkdir -p /home/hadoop/redis

$ cd /root/test/redis-cluster

$ mkdir 7001 7002 7003 8001 8002 8003 bin conf log rdb
