编辑server id

vim /data/bigdata/zookeeper/myid

按服务器编号依次输入1，2，3
（The myid file consists of a single line containing only the text of that machine's id. So myid of server 1 would contain the text "1" and nothing else. The id must be unique within the ensemble and should have a value between 1 and 255）
