MONGO集群搭建

一、系统环境

平台：Centos6.6_x86_64

实验环境：三台主机部署副本集模式集群

主机：10.218.145.189、10.218.145.190、10.218.145.191

规划：89为master节点，90为副本节点，91为副本节点

二、软件安装

1.软件安装

软件包：mongodb-linux-x86_64-rhel62-3.0.6.tgz

下载地址：wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.0.6.tgz

2.创建配置文件

dbpath = /disk1/mongo27018/data
port = 31111
pidfilepath = /usr/local/mongo27018/run/mongod.pid
fork = true
logpath = /disk1/mongo27018/log/mongodb.log
#unixSocketPrefix = /usr/local/mongo27018/run
logappend = true
journal = true
replSet = anav_push/10.218.145.189:31111,10.218.145.190:31111,10.218.145.191:31111
#replSet = anav_push
#keyFile = /usr/local/mongo27018/conf/keyfile27018.0
#auth = true
maxConns = 2000
oplogSize = 10240
storageEngine = wiredTiger
wiredTigerCacheSizeGB = 20
wiredTigerStatisticsLogDelaySecs = 0
wiredTigerJournalCompressor = snappy
wiredTigerDirectoryForIndexes = true
wiredTigerCollectionBlockCompressor = snappy
wiredTigerIndexPrefixCompression = 1

3.启动服务

4.设置集群信息

use admin

db.runCommand({"replSetInitiate"  { "_id" : "anav_push" ,"members" :
[ {"_id" : 1, "host" : "10.218.145.189:31111"},
{"_id" : 2, "host" : "10.218.145.190:31111"},
{"_id" : 3, "host" : "10.218.145.191:31111"}]
}})

5.连接数据库，插入一条数据

6.为数据库建立用户名密码

#建立用户名密码  http://www.cnblogs.com/zhoujinyi/p/4610050.html use admin
db.createUser(
{
user: "pushmongodb",
pwd: "push",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)

use gate2
db.createUser(
{
user: "pushmongodb",
pwd: "push",
roles: [ { role: "readWrite", db: "gate2" } ]
}
)
