二、测试
1、主节点写入数据，其他节点查询
repl:PRIMARY> use mtdamai;
switched to db mtdamai
repl:PRIMARY> db.user.insert({name:"wangxiuli"});
WriteResult({ "nInserted" : 1 })
repl:PRIMARY> db.user.find();
{ "_id" : ObjectId("554c237123db30ab1a233e4b"), "name" : "wangxiuli" }
#备节点查询发现已有数据
repl:SECONDARY> use mtdamai;
switched to db mtdamai
repl:SECONDARY> db.user.find();
{ "_id" : ObjectId("554c237123db30ab1a233e4b"), "name" : "wangxiuli" }
2、停止主节点
repl:SECONDARY> rs.status();
{
"set" : "repl",
"date" : ISODate("2015-05-08T02:51:25.273Z"),

}
],

}
#发现主节点已经重新被选出
再来插入数据验证
repl:PRIMARY> db.user.insert({name:"chenglong"});
WriteResult({ "nInserted" : 1 })
repl:PRIMARY> db.user.find();
{ "_id" : ObjectId("554c237123db30ab1a233e4b"), "name" : "wangxiuli" }
{ "_id" : ObjectId("554c25202dcdffb154643e56"), "name" : "chenglong" }
#验证备节点不可写
repl:SECONDARY> db.user.insert({name:"liudehua"});
WriteResult({ "writeError" : { "code" : undefined, "errmsg" : "not master" } })
#查询数据已存在，说明数据已同步到其他节点
repl:SECONDARY> use mtdamai;
switched to db mtdamai
repl:SECONDARY> db.user.find();
Error: error: { "$err" : "not master and slaveOk=false", "code" : 13435 }
repl:SECONDARY> rs.slaveOk();
repl:SECONDARY> db.user.find();
{ "_id" : ObjectId("554c237123db30ab1a233e4b"), "name" : "wangxiuli" }
{ "_id" : ObjectId("554c25202dcdffb154643e56"), "name" : "chenglong" }
#再次启动被关闭的节点，该节点变为secondary
repl:SECONDARY> rs.status();
{
"set" : "repl",
"date" : ISODate("2015-05-08T07:54:20.607Z"),
