集群三种角色：

"hosts" : [
                
                    "4:27018"
            ],
            "passives" : [
                    "8:27018"
            ],
            "arbiters" : [
                    "6:27018"
            ],

state状态含义：

*  0 = Starting up (phase 1)
 *  1 = Primary
 *  2 = Secondary
 *  3 = Recovering
 *  4 = Fatal error
 *  5 = Starting up (phase 2)
 *  6 = Unknown state
 *  7 = Arbiter
 *  8 = Down
