开始部署Redis+Cluster
# yum groupinstall "开发工具" -y
# chkconfig iptables off
# chkconfig --list iptables
iptables 0:关闭 1:关闭 2:关闭 3:关闭 4:关闭 5:关闭 6:关闭
# yum install wget vim -y
# cat /etc/selinux/config | head -7 | tail -1 | sed -i s@enforcing@disabled@g /etc/selinux/config
# hostname Redis
# cat /etc/sysconfig/network | sed -i s@localhost.localdomain@Redis@g /etc/sysconfig/network
# reboot
# wget http://download.redis.io/releases/redis-3.0.6.tar.gz
# tar xvzf redis-3.0.6.tar.gz
# mv redis-3.0.6 /usr/local/redis
# cd /usr/local/redis/
# make
# make install
# mkdir /usr/local/cluster
# cd /usr/local/cluster/
# mkdir 7000 7001 7002 7003 7004 7005
# cp /usr/local/redis/redis.conf /usr/local/cluster
# cd /usr/local/cluster/
# touch /usr/local/cluster/redis.conf
重点说明：下面这个第一行“port 7000”？因为创建了7000 7001 7002 7003 7004 7005 这6个，所以“port 7000”要根据不同的数字更改端口号！
# cat >/usr/local/cluster/redis.conf<<EOF
> port 7000
> daemonize yes
> cluster-enabled yes
> cluster-config-file nodes-6379.conf
> cluster-node-timeout 5000
> appendonly yes
> EOF
重点说明：cp复制完毕后，一定要更改各自的端口号呀！
# cp /usr/local/cluster/redis.conf /usr/local/cluster/7000/
# cp /usr/local/cluster/redis.conf /usr/local/cluster/7001/
# cp /usr/local/cluster/redis.conf /usr/local/cluster/7002/
# cp /usr/local/cluster/redis.conf /usr/local/cluster/7003/
# cp /usr/local/cluster/redis.conf /usr/local/cluster/7004/
# cp /usr/local/cluster/redis.conf /usr/local/cluster/7005/
# pwd
/usr/local/cluster/7000
# redis-server redis.conf
# redis-server redis.conf
# pwd
/usr/local/cluster/7001
# cd 7002/
# pwd
/usr/local/cluster/7002
# redis-server redis.conf
# cd 7003/
# pwd
/usr/local/cluster/7003
# redis-server redis.conf
# cd 7004/
# pwd
/usr/local/cluster/7004
# redis-server redis.conf
# cd 7005/
# pwd
/usr/local/cluster/7005
# redis-server redis.conf
重要说明：如果出现下面这些端口号进程？说明上面所有的配置成功！

"v001" 大神，有没有cluster迁移的操作啊？
