Centos7部署mongodb三节点复制集

一、安装mongodb

#使用yum安装mongodb

1、自定义yum源文件
vim /etc/yum.repos.d/mongodb.repo
[mongodb-org]
name=MongoDB Repository
baseurl=https://mirrors.aliyun.com/mongodb/yum/redhat/7/mongodb-org/4.2/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.2.asc

2、安装mongodb
yum install -y mongodb-org

二、复制集部署

2.1、修改配置文件

vim /etc/mongod.conf
# mongod.conf
# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/
# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log
# Where and how to store data.
storage:
  dbPath: /var/lib/mongo
  journal:
    enabled: true
#  engine:
#  wiredTiger:
# how the process runs
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo
# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.
#security:
#operationProfiling:
#replication:
replication:
  oplogSizeMB: 10240
  replSetName: 1data
#sharding:
## Enterprise-Only Options
#auditLog:
#snmp:

2.2、编写集群配置文件

vim /var/lib/mongo/rs.initiate.js
config ={
           "_id": "1data",
           "members": [
             {
                "_id": 0,
                "host": "10.10.101.22:27017"
             },
             {
                "_id": 1,
                "host": "10.10.101.23:27017"
             },
             {
                "_id": 2,
                "host": "10.10.101.24:27017"
             }
           ]
        }
rs.initiate(config)

2.3、使用配置文件，配置集群

mongo --port 27017 < /var/lib/mongo/rs.initiate.js

2.4、进入mongo，查看集群状态

[root@mongodb-0 ~]# mongo
1data:PRIMARY> rs.status()
