前言，以下是本人安裝mongodb4.0.5版本的操作 centos7.2系統(tǒng)
1、下載安裝包
wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/RPMS/mongodb-org-server-4.0.5-1.el7.x86_64.rpm
wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/RPMS/mongodb-org-shell-4.0.5-1.el7.x86_64.rpm
wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/RPMS/mongodb-org-tools-4.0.5-1.el7.x86_64.rpm
wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/RPMS/mongodb-org-mongos-4.0.5-1.el7.x86_64.rpm
2、安裝程序
安裝mongodb 服務(wù)端
rpm -ivh mongodb-org-server-4.0.5-1.el7.x86_64.rpm
如果還需要用命令行連接 mongoDB，則需要安裝 shell 程序包
rpm -ivh mongodb-org-shell-4.0.5-1.el7.x86_64.rpm
如果需要一些附加工具，例如數(shù)據(jù)導(dǎo)入導(dǎo)出旧蛾，則需要安裝 tool 程序包
rpm -ivh mongodb-org-tools-4.0.5-1.el7.x86_64.rpm
如果需要集群則需要安裝mongos
rpm -ivh mongodb-org-mongos-4.0.5-1.el7.x86_64.rpm
3、配置文件
安裝好了以后蠕嫁，會(huì)生成一個(gè) /etc/mongod.conf 的配置文件蚜点，配置了 mogoDB 默認(rèn)的配置。默認(rèn)的配置文件如下所示
# 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:
# mmapv1:
# 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: 127.0.0.1 # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.
#security:
#operationProfiling:
#replication:
#sharding:
## Enterprise-Only Options
#auditLog:
#snmp:
4拌阴、啟動(dòng)Mongodb
mongod -f /etc/mongod.conf
# 權(quán)限驗(yàn)證模式绍绘，只有權(quán)限驗(yàn)證通過才能訪問
mongod -f /etc/mongod.conf --auth
5、命令行使用
使用mongo命令連接顯示以下信息就連接成功了
# 連接
[root@zzapp-server-gp002 mongo]# mongo
MongoDB shell version v4.0.5
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("0301bb2a-0a7d-4a16-923d-3ec2946d08c6") }
MongoDB server version: 4.0.5

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
