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
[[email protected] ~]# wget --no-check-certificate https://github.com/ideawu/ssdb/archive/master.zip [[email protected] ~]# unzip master.zip [[email protected] ~]# cd ssdb-master [[email protected] ssdb-master]# make && make install
1.2.2 编辑双主配置文件
[[email protected] ~]# 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 [[email protected] ~]# 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
[[email protected] ~]# echo 'export PATH=$PATH:/usr/local/ssdb' >> /etc/profile [[email protected] ~]# source /etc/profile [[email protected] ~]# ssdb-server -d /usr/local/ssdb/ssdb.conf
