mongoDB 分片集群搭建

1.搭建环境

OS：centos7

mem：8G

2.软件版本

mongodb-linux-x86_64-3.2.22

端口规划 

		ip	port
mongos		127.0.0.1	28017
config	镜像	127.0.0.1	28018
	镜像	127.0.0.1	28019
	镜像	127.0.0.1	28020
shard1	p	127.0.0.1	28021
	s	127.0.0.1	28022
	s	127.0.0.1	28023
shard2	p	127.0.0.1	28024
	s	127.0.0.1	28025
	s	127.0.0.1	28026

3.搭建步骤

3.1 shard1集群

[root@db-test log]# cat /data/mongodb/28021/conf/mongod.conf
dbpath= /data/mongodb/28021/data
directoryperdb = true
logpath=/data/mongodb/28021/log/mongodb.log   
logappend=true
port=28021
pidfilepath=/data/mongodb/28021/log/mongodb.pid
syncdelay = 60
cpu = true
verbose = true
httpinterface = true 
noprealloc = true
replSet = flagm01
oplogSize = 2048
fork = true
keyFile=/data/mongodb/28021/conf/keyfile
auth = true
journal = true

 其他2个节点一致

3.2 shard2集群

[root@db-test log]# cat /data/mongodb/28024/conf/mongod.conf
dbpath= /data/mongodb/28024/data
directoryperdb = true
logpath=/data/mongodb/28024/log/mongodb.log   
logappend=true
port=28024
pidfilepath=/data/mongodb/28024/log/mongodb.pid
syncdelay = 60
cpu = true
verbose = true
httpinterface = true 
noprealloc = true
replSet = flagm02
oplogSize = 2048
fork = true
keyFile=/data/mongodb/28024/conf/keyfile
auth = true
journal = true

3.3 configserver

[root@db-test log]# cat /data/mongodb/28018/conf/mongod.conf
dbpath=/data/mongodb/28018/data
directoryperdb = true
logpath=/data/mongodb/28018/log/mongodb.log
logappend=true
port=28018
pidfilepath=/data/mongodb/28018/data/mongodb.pid
syncdelay = 60
cpu = true
verbose = true
httpinterface = true
noprealloc = true
oplogSize = 2048
fork = true
keyFile=/data/mongodb/28018/conf/keyfile
auth = true
journal = true
configsvr=true

storageEngine=wiredTiger
wiredTigerCacheSizeGB=1
wiredTigerDirectoryForIndexes=true
wiredTigerCollectionBlockCompressor=snappy
wiredTigerJournalCompressor=snappy
wiredTigerIndexPrefixCompression=1

3.4 mongos

[root@db-test log]# cat /data/mongodb/28017/conf/mongos.conf
configdb=localhost:28018,localhost:28019,localhost:28020
port=28017
chunkSize=100
keyFile=/data/mongodb/28017/data/keyfile
logpath=/data/mongodb/28017/log/mongos.log
fork=true
