        # bind to public ip
        #ip: 0.0.0.0

        slaveof:
            # to identify a master even if it moved(ip, port changed)
            # if set to empty or not defined, ip:port will be used.

            # sync|mirror, default is sync
            #type: sync
            #host: localhost

        output: log.txt
        rotate:
            size: 100000000
    
    leveldb:

        max_open_files: 1020000

load average 在15 - 18 之间  
连接数稳定在260 - 310之间
