ftp那边

redis-cli -h 10.1.10.133 -p 6379
redis 10.1.10.133:6379>bgsave
Background saving started
在后台异步(Asynchronously)保存当前数据库的数据到磁盘。
BGSAVE 命令执行之后立即返回 OK ，然后 Redis fork 出一个新子进程，
原来的 Redis 进程(父进程)继续处理客户端请求，而子进程则负责将数据保存到磁盘，然后退出。
http://redisdoc.com/   #redis命令参考

因为需要测试脚本是否能正常备份 需要安装redis-server和ftp
redis-server(centos6.6)epel源上就有
redis.x86_64 2.4.10-1.el6 @epel
redis-server(debian5.0.1)
wget mirror.wh-stuttgart.net/apt-mirror/packages.dotdeb.org/dists/wheezy/redis/binary-amd64/redis-server_2.6.14-1~dotdeb.1_amd64.deb
proftpd（debian5.0.1）
安装apt-get -y install proftpd

cat /etc/redis/redis.conf|egrep -v "^#|^$" |egrep "port|dbfilename|dir"
port 6379
dbfilename dump.rdb
dir /var/lib/redis

shell的内置命令命令exec
exec > ${logfile} 2>&1

cat /etc/debian_version
5.0.1
