以前写过一篇ruby on rails的文章，请参考：centos ruby on rails apache mysql 安装配置详解
喜欢手动编译的人，可以参考这篇文章，安装ruby.

# wget http://download.redis.io/releases/redis-3.0.7.tar.gz 
# tar -xvzf redis-3.0.7.tar.gz 
# cd redis-3.0.7 
# make && make install 
redis.conf （shirt g）
末尾加：路径/redis/local.conf
local.conf:
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

# sed -i "s/6379/6380/g"  redis.conf 将redis.conf文件中的6379替换为6380
如：
sed -i "s/redis6379/redis6379/g"  ./redis6379/redis.conf
sed -i "s/redis6379/redis6380/g"  ./redis6380/redis.conf
sed -i "s/redis6379/redis6381/g"  ./redis6381/redis.conf.

启动：./redis/src/redis-server ./redis/redis.conf > ./redis/redis.log 2>&1 &
如：
./redis6379/src/redis-server ./redis6379/redis.conf > ./redis6379/redis.log 2>&1 &
./redis6380/src/redis-server ./redis6380/redis.conf > ./redis6380/redis.log 2>&1 &
./redis6381/src/redis-server ./redis6381/redis.conf > ./redis6381/redis.log 2>&1 &

查看启动状态：netstat -tpnl |grep redis
