時(shí)間：2025-07-04 06:33:59 來(lái)源：y 點(diǎn)擊：697 次

這篇文章主要給大家介紹了關(guān)于mongodb 4.0副本集搭建的本集全過(guò)程，文中通過(guò)示例代碼介紹的搭建的全非常詳細(xì)，對(duì)大家學(xué)習(xí)或者使用mongodb 4.0具有一定的過(guò)程參考學(xué)習(xí)價(jià)值，需要的本集朋友們下面來(lái)一起學(xué)習(xí)學(xué)習(xí)吧

前言

近期有同學(xué)問(wèn)mongodb副本集難不難部署，我的搭建的全回答是不難，很快，過(guò)程幾分鐘搞定，本集比mysql MHA簡(jiǎn)單的搭建的全不止一點(diǎn)半點(diǎn)。那么到底如何部署呢？過(guò)程請(qǐng)看下文。

mongodb 4.0副本集搭建的全過(guò)程

1. 準(zhǔn)備工作

mongodb 4.0副本集搭建的全過(guò)程

1.1 下載軟件

選擇版本并下載mongodb的本集軟件，注意操作系統(tǒng)版本等。搭建的全本次我選用的過(guò)程是percona分支的mongodb 4.2.8版本搭建，操作系統(tǒng)為centos6

cd /usr/local/
wget https://www.percona.com/downloads/percona-server-mongodb-LATEST/percona-server-mongodb-4.2.8-8/binary/tarball/percona-server-mongodb-4.2.8-8-centos6-x86_64.tar.gz
tar -zxvf percona-server-mongodb-4.2.8-8-centos6-x86_64.tar.gz
ln -s percona-server-mongodb-4.2.8-8 mongodb

1.2 規(guī)劃各節(jié)點(diǎn)角色

各節(jié)點(diǎn)角色如下

IP　port　role

192.168.128.20827017PRIMARY

192.168.128.20927017SECONDARY

192.168.128.20928017ARBITER

2 部署

2.1 創(chuàng)建各節(jié)點(diǎn)相關(guān)目錄

創(chuàng)建數(shù)據(jù)目錄、本集日志目錄等相關(guān)目錄

[root@m1 ~]# mkdir -p /data/mongodb/27017/{ data,搭建的全logs,tmp,etc,keyfile}
[root@m1 ~]# cd /data/mongodb/27017/
[root@m1 27017]# ll
總用量 20
drwxr-xr-x 2 root root 4096 8月 7 16:59 data
drwxr-xr-x 2 root root 4096 8月 7 16:59 etc
drwxr-xr-x 2 root root 4096 8月 7 16:59 keyfile
drwxr-xr-x 2 root root 4096 8月 7 16:59 logs
drwxr-xr-x 2 root root 4096 8月 7 16:59 tmp

2.2 配置文件

創(chuàng)建配置文件，并添加對(duì)應(yīng)的過(guò)程配置信息，注意仲裁節(jié)點(diǎn)的端口

[root@m1 27017]# cd /data/mongodb/27017/etc/
[root@m1 etc]# vim mongod.conf
添加如下內(nèi)容

storage:
dbPath: /data/mongodb/27017/data
journal:
enabled: true
systemLog:
destination: file
logAppend: true
path: /data/mongodb/27017/logs/mongod.log
processManagement:
fork: true
pidFilePath: /data/mongodb/27017/tmp/mongod.pid
net:
port: 27017
bindIp: 0.0.0.0replication: replSetName: "test1" # 副本集名稱

2.3 啟動(dòng)各節(jié)點(diǎn)

以其中一個(gè)節(jié)點(diǎn)為例，其他節(jié)點(diǎn)修改對(duì)應(yīng)配置文件即可

[root@m1 local]# /usr/local/mongodb/bin/mongod -f /data/mongodb/27017/etc/mongod.conf
about to fork child process, waiting until server is ready for connections.
forked process: 30019
child process started successfully, parent exiting

2.4 初始化副本集

初始化副本集，指定各節(jié)點(diǎn)id及角色，注意副本集的名稱和配置文件里一致。

在任意節(jié)點(diǎn)執(zhí)行如下語(yǔ)句

> use admin
switched to db admin
> rs.initiate( {
... _id: "test1",
... members: [
... { _id: 0, host: "192.168.128.208:27017" },
... { _id: 1, host: "192.168.128.209:27017" },
... { _id: 2, host: "192.168.128.209:28017",arbiterOnly:true }
... ] })
{
"ok" : 1,
"$clusterTime" : {
"clusterTime" : Timestamp(1596792682, 1),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
},
"operationTime" : Timestamp(1596792682, 1)
}

完成后可以查看各集群狀態(tài),如下，可見(jiàn)當(dāng)前192.168.128.208:27017 為PRIMARY節(jié)點(diǎn)

test1:PRIMARY>

3 修改為認(rèn)證模式

為考慮安全性等，需要開啟認(rèn)證模式（需要通過(guò)用戶名/密碼方式登錄）

3.1 創(chuàng)建用戶

創(chuàng)建超級(jí)管理員賬號(hào)

test1:PRIMARY> db.createUser({ user: "root", pwd: "Root#123", roles: [{ role: "root", db: "admin"}]})
Successfully added user: {
"user" : "root",
"roles" : [
{
"role" : "root",
"db" : "admin"
}
]
}

3.2 創(chuàng)建key文件

在主庫(kù)上執(zhí)行腳本生成key文件，然后將結(jié)拷貝到另外2個(gè)節(jié)點(diǎn)

[root@m1 mongodb]# cd /data/mongodb/27017/keyfile/

[root@m1 keyfile]# openssl rand -base64 756 > mongo.key

[root@m1 keyfile]# chmod 600 mongo.key # 必須修改為600權(quán)限，否則無(wú)法啟動(dòng)

以上完成后，將文件復(fù)制到另外2個(gè)節(jié)點(diǎn)

3.3 修改配置文件

配置文件中添加如下內(nèi)容，注意不同節(jié)點(diǎn)的文件路徑

security:

authorization: enabled

clusterAuthMode: keyFile

keyFile: /data/mongodb/27017/keyfile/mongo.key

3.4 重啟后并用認(rèn)證模式登陸

# 關(guān)閉mongodb
[root@m1 keyfile]# /usr/local/mongodb/bin/mongod -f /data/mongodb/27017/etc/mongod.conf -shutdown
killing process with pid: 30675
# 啟動(dòng)mongodb
[root@m1 keyfile]# /usr/local/mongodb/bin/mongod -f /data/mongodb/27017/etc/mongod.conf about to fork child process, waiting until server is ready for connections.
forked process: 2430

child process started successfully, parent exiting

# 認(rèn)證模式登陸
[root@m1 keyfile]#
[root@m1 keyfile]# /usr/local/mongodb/bin/mongo -u root -p 'Root#123' --authenticationDatabase admin

至此，mongodb 副本集搭建完畢，你會(huì)了嗎？
