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
gem-redis
[hadoop@hadoop01 ~]$ sudo gem install redis --version 3.0.0 Successfully installed redis-3.0.0 1 gem installed Installing ri documentation for redis-3.0.0... Installing RDoc documentation for redis-3.0.0...
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"
数据测试：
redis-benchmark -l
分布式集群安装
创建本地测试目录
$ mkdir -p /home/hadoop/redis $ cd /root/test/redis-cluster $ mkdir 7001 7002 7003 8001 8002 8003 bin conf log rdb
结构如下：
