unzip master
cd ssdb-master
make
# 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
