MongoDB 4.0 开发环境搭建集群
本文内容纲要:
-环境准备
-MongoDB安装
-集群搭建
环境准备
Liunx服务器一台
以下示例为单机版安装集群,没有分片
MongoDB安装
1.下载MongoDBtgz安装包:
可以从下载中心下载:
https://www.mongodb.com/download-center#production
Shell:
wgethttps://fastdl.mongodb.org/linux/mongodb-linux-x86_64-amazon2-4.0.1.tgz
2.解压缩下载的压缩文件
使用下面的命令解压缩刚才下载的文件
tar-zxvfmongodb-linux-*-4.0.1.tgz
3.添加路径到环境变量
打开/etc/profile
,然后添加下面的脚本进去:
exportPATH=<mongodb-install-directory>/bin:$PATH
为你的程序安装目录,然后刷新环境变量:
source/etc/profile
集群搭建
1.为每个实例创建目录
创建文件夹:
mkdir-p/opt/mongodb/rs0-0/opt/mongodb/rs0-1/opt/mongodb/rs0-2
2.创建配置文件
切换到rs0-0目录中,创建配置文件touchmongod.conf
,内容为:
#mongod.conf
systemLog:
destination:file
logAppend:true
path:/opt/mongodb/rs0-0/logs/mongodb.log
storage:
dbPath:/opt/mongodb/rs0-0/data
journal:
enabled:true
processManagement:
fork:true#forkandruninbackground
pidFilePath:/opt/mongodb/rs0-0/mongod.pid#locationofpidfile
timeZoneInfo:/usr/share/zoneinfo
net:
port:27017
bindIp:0.0.0.0#Listentolocalinterfaceonly,commenttolistenonallinterfaces.
replication:
replSetName:rs0
切换到rs0-1目录中,创建配置文件touchmongod.conf
,内容为:
#mongod.conf
systemLog:
destination:file
logAppend:true
path:/opt/mongodb/rs0-1/logs/mongodb.log
storage:
dbPath:/opt/mongodb/rs0-1/data
journal:
enabled:true
processManagement:
fork:true#forkandruninbackground
pidFilePath:/opt/mongodb/rs0-1/mongod.pid#locationofpidfile
timeZoneInfo:/usr/share/zoneinfo
net:
port:27018
bindIp:0.0.0.0#Listentolocalinterfaceonly,commenttolistenonallinterfaces.
replication:
replSetName:rs0
切换到rs0-2目录中,创建配置文件touchmongod.conf
,内容为:
#mongod.conf
systemLog:
destination:file
logAppend:true
path:/opt/mongodb/rs0-2/logs/mongodb.log
storage:
dbPath:/opt/mongodb/rs0-2/data
journal:
enabled:true
processManagement:
fork:true#forkandruninbackground
pidFilePath:/opt/mongodb/rs0-2/mongod.pid#locationofpidfile
timeZoneInfo:/usr/share/zoneinfo
net:
port:27019
bindIp:0.0.0.0#Listentolocalinterfaceonly,commenttolistenonallinterfaces.
replication:
replSetName:rs0
3.启动实例
实例0:
mongod--replSetrs0--port27017--smallfiles--oplogSize128
实例1:
mongod--replSetrs0--port27018--smallfiles--oplogSize128
实例2:
mongod--replSetrs0--port27019--smallfiles--oplogSize128
4.配置集群
启动起来之后,使用mongo客户端命令切换到其中一个实例上
mongo--port27017
然后在Mongoshell中输入:
rsconf={
_id:"rs0",
members:[
{
_id:0,
host:"<hostname>:27017"
},
{
_id:1,
host:"<hostname>:27018"
},
{
_id:2,
host:"<hostname>:27019"
}
]
}
替换为你的主机名或者ip地址,然后执行:
rs.initiate(rsconf)
输入rs.conf()
来查看你的集群信息:
{
"_id":"rs0",
"version":1,
"protocolVersion":NumberLong(1),
"writeConcernMajorityJournalDefault":true,
"members":[
{
"_id":0,
"host":"<hostname>:27017",
"arbiterOnly":false,
"buildIndexes":true,
"hidden":false,
"priority":1,
"tags":{},
"slaveDelay":NumberLong(0),
"votes":1
},
{
"_id":1,
"host":"<hostname>:27018",
"arbiterOnly":false,
"buildIndexes":true,
"hidden":false,
"priority":1,
"tags":{},
"slaveDelay":NumberLong(0),
"votes":1
},
{
"_id":2,
"host":"<hostname>:27019",
"arbiterOnly":false,
"buildIndexes":true,
"hidden":false,
"priority":1,
"tags":{},
"slaveDelay":NumberLong(0),
"votes":1
}
],
"settings":{
"chainingAllowed":true,
"heartbeatIntervalMillis":2000,
"heartbeatTimeoutSecs":10,
"electionTimeoutMillis":10000,
"catchUpTimeoutMillis":-1,
"catchUpTakeoverDelayMillis":30000,
"getLastErrorModes":{},
"getLastErrorDefaults":{
"w":1,
"wtimeout":0
},
"replicaSetId":ObjectId("5b7412b72362045708008077")
}
}
