mongodb项目实战与高级应用（MongoDB 高可用方案-MongoDB 数据分片搭建）

和Replica Set 类似，都需要一个仲裁节点，但是Sharding 还需要配置节点和路由节点。就三种集
群搭建方式来说，这种是最复杂的。
配置数据节点

mkdir -p /opt/mongodb/shard/replset/replica1/data
mkdir -p /opt/mongodb/shard/replset/replica1/logs
mkdir -p /opt/mongodb/shard/replset/replica2/data
mkdir -p /opt/mongodb/shard/replset/replica2/logs
mkdir -p /opt/mongodb/shard/replset/replica3/data
mkdir -p /opt/mongodb/shard/replset/replica3/logs

vi /opt/mongodb/shard/replset/replica1/mongodb.cfg
 

dbpath=/opt/mongodb/shard/replset/replica1/data
