MongoDB4.0.2集群搭建
根据对象存储平台Django+MongoDB+Ceph的需求,现搭建部署一个十节点的MongoDB集群,主要以下关键点:
根据最新版本MongoDB推荐,配置文件采用yaml方式来配置
一共10台服务器,即10个节点。对数据集进行分片,共分10个shard
每一个shard都进行副本集配置,由于硬件磁盘已进行raid多副本备份,考虑到存储效率,本集群在副本集只需要一个备服务器,故采用1主+1备
+1仲裁(必须有仲裁节点,不然被服务器无法通过心跳机制升级为主服务器)的副本及配置方式
环境准备
系统:CentOS7.0 64bit
十台服务器:mongo00-mongo09
服务器规划:
mongo00 | mongo01 | mongo02 | mongo03 | mongo04 | mongo05 | mongo06 | mongo07 | mongo08 | mongo09 |
---|---|---|---|---|---|---|---|---|---|
mongos | mongos | mongos | mongos | mongos | mongos | mongos | config | config | config |
shard0主 | shard1主 | shard2主 | shard3主 | shard4主 | shard5主 | shard6主 | shard7主 | shard8主 | shard9主 |
shard9副 | shard0副 | shard1副 | shard2副 | shard3副 | shard4副 | shard5副 | shard6副 | shard7副 | shard8副 |
shard8仲 | shard9仲 | shard0仲 | shard1仲 | shard2仲 | shard3仲 | shard4仲 | shard5仲 | shard6仲 | shard7仲 |
端口分配:
