SSDB簡介

SSDB 是一個 C/C++ 語言開發的高性能 NoSQL 數據庫, 支持 KV, list, map(hash), zset(sorted set) 等數據結構, 用來替代或者與 Redis 配合存儲十億級別列表的數據.

SSDB 是穩定的, 生產環境使用的, 已經在許多互聯網公司得到廣泛使用, 如奇虎 360, TOPGAME.

下載和安裝

wget --no-check-certificate https://github.com/ideawu/ssdb/archive/master.zip
unzip master
cd ssdb-master
make
# 將安裝在 /usr/local/ssdb 目錄下
sudo make install

啟動和停止

# 啟動主庫, 此命令會阻塞住命令行
./ssdb-server ssdb.conf

# 或者啟動為後臺進程(不阻塞命令行)
./ssdb-server -d ssdb.conf

# 停止 ssdb-server
./ssdb-server ssdb.conf -s stop
# 對於舊版本
kill `cat ./var/ssdb.pid`

# 重啟
./ssdb-server ssdb.conf -s restart

重啟SSDB

安裝配置haproxy

yum  -y install  haproxy
vim /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/stats
defaults
    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                 3000
listen test
bind 0.0.0.0:8899
mode tcp
balance roundrobin
server s1 10.105.10.128:8888 weight 1 maxconn 10000 check inter 10s
server s2 10.105.10.77:8888 weight 1 maxconn 10000 check inter 10s

重新啟動haproxy,以後可以利用keepalive 將haproxy設計成雙主或準備都可以

/etc/init.d/haproxy restart

測試（客戶端連接haproxy地址）
