SSDB是一个高性能的支持丰富数据结构的 NoSQL 数据库, 用于替代 Redis或者与 Redis 配合存储十亿级别列表的数据，现在已被许多知名企业所应用。我们使用SSDB是想将现有的redis中的key迁移到SSDB以破除现有的redis 120G存储极限（当然可以扩展，但是计算了下成本就打算放弃了）。

Twemproxy是twtter开源的一个redis和memcache代理服务器，这里我们使用Twemproxy代理来代理SSDB集群来实现数据的分布式存储，即shared。

1、节点规划：

Twemproxy 192.168.0.100

ssdb1 master 192.168.0.101

ssdb1 slave 192.168.0.102

ssdb2 master 192.168.0.103

ssdb2 slave 192.168.0.104

2、安装SSDB

## 解压下载好的ssdb软件包 $ unzip ssdb-master.zip ## 安装gcc、gcc-c++ 、make等工具 ##编译、安装ssdb，会安装在/usr/local/ssdb/下面 $ cd ssdb-master $ make &&make install ## 进入安装目录 $ cd/usr/local/ssdb/ ## 启动ssdb-server $ ./ssdb-server -dssdb.conf ssdb 1.8.2 Copyright (c)2012-2014 ssdb.io ## 验证是否启动成功,若8888端口被监听，则表示成功 $ netstat-alnut|grep 8888 tcp 0 0 127.0.0.1:8888 0.0.0.0:* LISTEN ## 客户端连接 $ ./ssdb-cli -p8888 ssdb (cli) - ssdb command line tool. Copyright (c)2012-2014 ssdb.io 'h' or 'help' forhelp, 'q' to quit. server version:1.8.2 ssdb 127.0.0.1:8888>

3、主从配置，以ssdb1为例

## 修改ssdb1 master的配置文件，如下 # ssdb-server config # MUST indent by TAB! # relative to path of this file, directorymust exists work_dir = ./var pidfile = ./var/ssdb.pid server: ip:192.168.0.101 port:8888 # bind to public ip #ip: 0.0.0.0 # format: allow|deny: all|ip_prefix # multiple allows or denys is supported #deny: all #allow: 127.0.0.1 #allow: 192.168 # auth password must be at least 32 characters #auth: very-strong-password replication: binlog: yes # Limit sync speed to *MB/s, -1: no limit sync_speed: -1 slaveof: # to identify a master even ifit moved(ip, port changed) # if set to empty or notdefined, ip:port will be used. #id: svc_2 # sync|mirror, default is sync #type: sync #ip: 127.0.0.1 #port: 8889 logger: level: debug output: log.txt rotate: size: 1000000000 leveldb: # in MB cache_size: 500 # in KB block_size: 32 # in MB write_buffer_size: 64 # in MB compaction_speed: 1000 # yes|no compression: yes ## 修改ssdb1 slave的配置文件，如下 # ssdb-server config # MUST indent by TAB! # relative to path of this file, directorymust exists work_dir = ./var pidfile = ./var/ssdb.pid server: ip: 192.168.0.102 port: 8888 # bind to public ip #ip: 0.0.0.0 # format: allow|deny: all|ip_prefix # multiple allows or denys is supported #deny: all #allow: 127.0.0.1 #allow: 192.168 # auth password must be at least 32 characters #auth: very-strong-password replication: binlog:yes # Limit sync speed to *MB/s, -1: no limit sync_speed: -1 slaveof: # to identify a master even if itmoved(ip, port changed) # if set to empty or notdefined, ip:port will be used. id: svc_1 # sync|mirror, default is sync type:sync ip: 192.168.0.101 port:8888 logger: level: debug output: log.txt rotate: size: 1000000000 leveldb: # in MB cache_size: 500 # in KB block_size: 32 # in MB write_buffer_size: 64 # in MB compaction_speed: 1000 # yes|no compression: yes
