SSDB高可用方案

SSDB简介

SSDB 是一个 C/C++ 语言开发的高性能 NoSQL 数据库, 支持 KV, list, map(hash), zset(sorted set) 等数据结构, 用来替代或者与 Redis 配合存储十亿级别列表的数据.

SSDB 是稳定的, 生产环境使用的, 已经在许多互联网公司得到广泛使用, 如奇虎 360, TOPGAME.

下载和安装

wget --no-check-certificate https://github.com/ideawu/ssdb/archive/master.zipunzip mastercd ssdb-mastermake# 将安装在 /usr/local/ssdb 目录下sudo make install

启动和停止

# 启动主库, 此命令会阻塞住命令行./ssdb-server ssdb.conf# 或者启动为后台进程(不阻塞命令行)./ssdb-server -d ssdb.conf# 停止 ssdb-server./ssdb-server ssdb.conf -s stop# 对于旧版本kill `cat ./var/ssdb.pid`# 重启./ssdb-server ssdb.conf -s restart

双主方案

重启ssdb

master-2:10.105.10.128

work_dir = ./varpidfile = ./var/ssdb.pidserver:        ip: 0.0.0.0        port: 8888replication:        binlog: yes        sync_speed: -1        slaveof:                id: svc_2                type: sync                host: 10.105.10.77                port: 8888logger:        level: info        output: log.txt        rotate:                size: 1000000000leveldb:        cache_size: 500        block_size: 32        write_buffer_size: 64        compaction_speed: 1000        compression: yes

重启SSDB

安装配置haproxy

yum  -y install  haproxyvim /etc/haproxy/haproxy.cfg

global    log         127.0.0.1 local2    chroot      /var/lib/haproxy    pidfile     /var/run/haproxy.pid    maxconn     4000    user        haproxy    group       haproxy    daemon    stats socket /var/lib/haproxy/statsdefaults    mode                    http    log                     global    option                  dontlognull    option                  redispatch    retries                 3    timeout http-request    10s    timeout queue           1m    timeout connect         10s    timeout client          1m    timeout server          1m    timeout http-keep-alive 10s    timeout check           10s    maxconn                 3000listen testbind 0.0.0.0:8899mode tcpbalance roundrobinserver s1 10.105.10.128:8888 weight 1 maxconn 10000 check inter 10sserver s2 10.105.10.77:8888 weight 1 maxconn 10000 check inter 10s

重新启动haproxy,以后可以利用keepalive 将haproxy设计成双主或准备都可以

/etc/init.d/haproxy restart

测试（客户端连接haproxy地址）
