简介

MongoDB stores data in flexible, JSON-like documents, meaning fields can vary from document to document and data structure can be changed over time

The document model maps to the objects in your application code, making data easy to work with
Ad hoc queries, indexing, and real time aggregation provide powerful ways to access and analyze your data
MongoDB is a distributed database at its core, so high availability, horizontal scaling, and geographic distribution are built in and easy to use
MongoDB is free and open-source, published under the GNU Affero General Public License

安装配置

1.环境

Linux(CentOS release 6.9 )系统服务器3台:

ip:192.168.1.200

ip:192.168.1.202

ip:192.168.1.203

2.Mongodb cluster角色

Shard Server:

(复制集名称rs[\d+])/(主节点master)+(从节点slaver+仲裁节点arbiterOnly)

rs1/192.168.1.200:27017,192.168.1.202:27017,192.168.1.203:27017

rs2/192.168.1.200:27018,192.168.1.202:27018,192.168.1.203:27018

rs3/192.168.1.200:27019,192.168.1.202:27019,192.168.1.203:27019

Config Server:

mongodb3.x config-server require cluster model

{ _id:"crs1", members:[ {_id:0,host:'192.168.1.200:20000',priority:2}, {_id:1,host:'192.168.1.202:20000',priority:1}, {_id:2,host:'192.168.1.203:20000',arbiterOnly:true}] };

RouteServer:

192.168.1.200:30000

192.168.1.202:30000

192.168.1.203:30000

3.安装：

a.解压：tar xvf mongodb-linux-x86_64-3.6.3.tgz

b.配置/etc/profile

export MONGO_HOME=/home/mongodb/mongodb-linux-x86_64-3.6.3

export PATH=$MONGO_HOME/bin:$mysql_HOME/bin:$JAVA_HOME/bin:$PATH

c.生效配置

source /etc/profile

d.创建目录：

mkdir -p home/mongodb/cluster

cd home/mongodb/cluster

mkdir config data logs

创建分片 shared1 shared2 shared3 数据目录

cd data

mkdir config shared1 shared2 shared3

4.配置config文件：

cd home/mongodb/cluster

配置shared1.conf shared2.conf shared3.conf

5.设置复制集

启动mongo服务

192.168.1.[200|202|203]服务器均启动此脚本：

mongod -f /home/mongodb/cluster/shared1.conf

mongod -f /home/mongodb/cluster/shared2.conf

mongod -f /home/mongodb/cluster/shared3.conf

配置replicaset(rs1)

[root@base_ci ~]# mongo 192.168.1.200:27017

> use admin

switched to db admin

> cfg={ _id:"rs1", members:[ {_id:0,host:'192.168.1.200:27017',priority:2}, {_id:1,host:'192.168.1.202:27017',priority:1}, {_id:2,host:'192.168.1.203:27017',arbiterOnly:true}] };

> rs.initiate(cfg)

{ "ok" : 1 }

配置replicaset(rs2)

[root@base_ci ~]# mongo 192.168.1.200:27018

> use admin

switched to db admin

> cfg={ _id:"rs2", members:[ {_id:0,host:'192.168.1.200:27018',priority:2}, {_id:1,host:'192.168.1.202:27018',priority:1}, {_id:2,host:'192.168.1.203:27018',arbiterOnly:true}] };

> rs.initiate(cfg)

{ "ok" : 1 }

配置replicaset(rs3)

[root@base_ci ~]# mongo 192.168.1.200:27019

> use admin

switched to db admin

> cfg={ _id:"rs3", members:[ {_id:0,host:'192.168.1.200:27019',priority:2}, {_id:1,host:'192.168.1.202:27019',priority:1}, {_id:2,host:'192.168.1.203:27019',arbiterOnly:true}] };

> rs.initiate(cfg)

{ "ok" : 1 }

6.设置配置服务config server：

启动config server 服务(192.168.1.[200|202|203]服务器均启动此脚本)

mongod -f /home/mongodb/cluster/config.conf

连接：

mongo 192.168.1.200:20000/admin

配置

configsvr>cfg={ _id:"crs1", members:[ {_id:0,host:'192.168.1.200:20000',priority:1}, {_id:1,host:'192.168.1.202:20000',priority:1}, {_id:2,host:'192.168.1.203:20000',priority:1}] };

configsvr> rs.initiate(cfg);

7.设置路由服务router server：
