centos7.9使用yum方式安裝MongoDB 5.x

1.配置阿里雲yum倉庫

#vim /etc/yum.repos.d/mongodb-org-5.0.repo 

[mngodb-org]
name=MongoDB Repository
baseurl=http://mirrors.aliyun.com/mongodb/yum/redhat/7Server/mongodb-org/5.0/x86_64/
gpgcheck=0
enabled=1

2.安裝

yum clean all
yum makecache
yum -y install mongodb-org-server
yum -y install mongodb-org-shell

3.修改配置文件
配置文件路徑：/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: # 日志存放路徑
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log  # 修改為/server/mongo/log/mongod.log

# Where and how to store data.
storage: # 數據存放路徑
  dbPath: /var/lib/mongo # 修改為/server/mongo/data
  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 # # 修改為/server/mongo/pid/mongod.pid
  timeZoneInfo: /usr/share/zoneinfo

# network interfaces
net: # 監控ip和端口
  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.

若是需要存儲數據，日志等到其他地方，比如統一使用/server/mongo路徑，除了修改配置文件外，還需要修改mongod.service文件內容

mkdir -p /server/mongo/{data,log,pid}

[Install]
WantedBy=multi-user.target

systemctl daemon-reload

4.啟動，停止等操作

啟動mongodb ：systemctl start mongod.service
停止mongodb ：systemctl stop mongod.service
開機啟動mongodb ：systemctl enable mongod.service

5.設置超級管理員賬號信息等

mongo # 開啟客戶端登陸,需要確保配置文件中監聽的地址是127.0.0.1，其他監聽地址會報錯
use admin # 切換admin數據庫
db.createUser(
  {
    user: "adminUser",
    pwd: "adminPass",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)

操作完畢后退出

6.修改配置文件，設置訪問ip和開啟賬號驗證

vim /etc/mongod.conf
net:
  port: 27017
  bindIp: 0.0.0.0 # 等創建好管理員后再修改監聽地址
security:
  authorization: enabled

systemctl restart mongod.service

7.創建普通用戶賬號密碼等

mongo
use admin
db.auth("adminUser","adminPass") # 老版本的是user.auth("adminUser","adminPass")

use osr_web # 切換數據庫，有則切換，沒有則創建
# 創建數據庫關聯的用戶名和密碼，以及讀寫權限等
db.createUser({
  user: 'root',
  pwd: 'root',
  roles:[{
    role: 'readWrite',
    db: 'osr_web'
  }]
})

8.可以使用軟件Navicat Premium 12連接查看
