SSDB高可用方案

SSDB簡(jiǎn)介

SSDB 是一個(gè) C/C++ 語(yǔ)言開發(fā)的高性能 NoSQL 數(shù)據(jù)庫(kù), 支持 KV, list, map(hash), zset(sorted set) 等數(shù)據(jù)結(jié)構(gòu), 用來(lái)替代或者與 Redis 配合存儲(chǔ)十億級(jí)別列表的數(shù)據(jù).

SSDB 是穩(wěn)定的, 生產(chǎn)環(huán)境使用的, 已經(jīng)在許多互聯(lián)網(wǎng)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(dòng)和停止

# 啟動(dòng)主庫(kù), 此命令會(huì)阻塞住命令行
./ssdb-server ssdb.conf

# 或者啟動(dòng)為后臺(tái)進(jìn)程(不阻塞命令行)
./ssdb-server -d ssdb.conf

# 停止 ssdb-server
./ssdb-server ssdb.conf -s stop
# 對(duì)于舊版本
kill `cat ./var/ssdb.pid`

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

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(dòng)haproxy,以后可以利用keepalive 將haproxy設(shè)計(jì)成雙主或準(zhǔn)備都可以

/etc/init.d/haproxy restart

測(cè)試（客戶端連接haproxy地址）
