mongo复制集同步验证的实例详解
第一步：在主节点上插入一条数据
Sql代码
rs0:PRIMARY> use imooc switched to db imooc rs0:PRIMARY> db.imooc.insert({
"name":"imooc"}
) WriteResult({
"nInserted" : 1 }
)
第二步：在从节点查看数据，看是否同步
Sql代码
rs0:SECONDARY> use imooc switched to db imooc rs0:SECONDARY> show tables 2017-06-14T19:33:06.118+0800 E QUERY [thread1] Error: listCollections failed: {
