节点的动态增删
增加节点
rs.add("192.168.181.135:37019")
删除slave 节点
rs.remove("192.168.181.135:37019")
调整复制集配置
var conf = rs.conf()
// 将0号节点的优先级调整为10
conf.members[0].priority = 10;
// 将1号节点调整为hidden节点
conf.members[1].hidden = true;
// hidden节点必须配置{priority: 0}
conf.members[1].priority = 0;
// 应用以上调整
rs.reconfig(conf);
其它配置
# /usr/local/mongodb/mongodb.conf

有仲裁节点复制集搭建
_id 整数 _id:0 复制集中的标示
host 字符串 host:“主机:端口” 节点主机名
arbiterOnly 布尔值 arbiterOnly:true 是否为仲裁(裁判)节点
priority（权重）
整数 priority=0|1 默认1，是否有资格变成主节点，取值范围0-1000，0永远不
会变成主节点
hidden 布尔值 hidden=true|false，0|1 隐藏，权重必须为0，才可以设置
votes 整数 votes= 0|1 投票，是否为投票节点,0 不投票，1投票
slaveDelay 整数 slaveDelay=3600 从库的延迟多少秒
buildIndexes 布尔值 buildIndexes=true|false,0|1 主库的索引，从库也创建，_id索引无效
和上面的配置步骤相同 只是增加了 一个特殊的仲裁节点
注入节点 执行 rs.addArb(“IP:端口”);
rs.addArb(“192.168.181.135:27020”)
或者重新配置
只能在主节点下进行
