WEB架构之存储-SSDB（03）

1.1 SSDB介绍

SSDB一个高性能的支持丰富数据结构的 NoSQL 数据库, 用于替代 Redis。

1.1.1 SSDB特性

• 替代 Redis 数据库, Redis 的 100 倍容量
• LevelDB 网络支持, 使用 C/C++ 开发
• Redis API 兼容, 支持 Redis 客户端
• 适合存储集合数据, 如 list, hash, zset…
• 客户端 API 支持的语言包括: C++, PHP, Python, Java, Go
• 持久化的队列服务
• 主从复制, 负载均衡

1.1.2 SSDB与Redis性能对比

1.2 部署SSDB主-主同步

1.2.1 编译安装SSDB

[root@ssdb-node ~]# wget --no-check-certificate https://github.com/ideawu/ssdb/archive/master.zip
[root@ssdb-node ~]# unzip master.zip
[root@ssdb-node ~]# cd ssdb-master
[root@ssdb-node ssdb-master]# make && make install

1.2.2 编辑双主配置文件

[root@ssdb-node01 ~]# vim /usr/local/ssdb/ssdb.conf
server:
        # specify an ipv6 address to enable ipv6 support
        # ip: ::1
        ip: 0.0.0.0
        port: 8888
replication:
        binlog: yes
        # Limit sync speed to *MB/s, -1: no limit
        sync_speed: -1
        slaveof:
                # to identify a master even if it moved(ip, port changed)
                # if set to empty or not defined, ip:port will be used.
                id: svc_1
                # sync|mirror, default is sync
                type: mirror
                host: 10.10.10.104  # 对端主服务器IP
                port: 8888          # 对端主服务器端口

[root@ssdb-node02 ~]# vim /usr/local/ssdb/ssdb.conf
server:
        # specify an ipv6 address to enable ipv6 support
        # ip: ::1
        ip: 0.0.0.0
        port: 8888
replication:
        binlog: yes
        # Limit sync speed to *MB/s, -1: no limit
        sync_speed: -1
        slaveof:
                # to identify a master even if it moved(ip, port changed)
                # if set to empty or not defined, ip:port will be used.
                id: svc_2
                # sync|mirror, default is sync
                type: mirror
                host: 10.10.10.103  # 对端主服务器IP
                port: 8888          # 对端主服务器端口

1.2.3 启动服务

[root@ssdb-node ~]# echo 'export PATH=$PATH:/usr/local/ssdb' >> /etc/profile
[root@ssdb-node ~]# source /etc/profile
[root@ssdb-node ~]# ssdb-server -d /usr/local/ssdb/ssdb.conf

1.2.4 验证运行结果

[root@ssdb-node01 ~]# ssdb-cli 10.10.10.103
