1.配置阿里云yum仓库

#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.安装

yum clean all
yum make cache
yum -y install mongodb-org

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

# Where and how to store data.
storage: # 数据存放路径
  dbPath: /var/lib/mongo # 修改为/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 # # 修改为/server/mongo/pid/mongod.pid
  timeZoneInfo: /usr/share/zoneinfo

# network interfaces
net: # 监控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.

若是需要存储数据，日志等到其他地方，比如统一使用/server/mongo路径，除了修改配置文件外，还需要修改mongod.service文件内容

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

[Install]
WantedBy=multi-user.target

systemctl daemon-reload

4.启动，停止等操作

启动mongodb ：systemctl start mongod.service
停止mongodb ：systemctl stop mongod.service
开机启动mongodb ：systemctl stop mongod.service

5.设置超级管理员账号信息等

mongo # 开启客户端登陆
use admin # 切换admin数据库
db.createUser(
  {
    user: "adminUser",
    pwd: "adminPass",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)

操作完毕后退出

6.修改配置文件，设置访问ip和开启账号验证

vim /etc/mongod.conf
net:
  port: 27017
  bindIp: 0.0.0.0
security:
  authorization: enabled

systemctl restart mongod.service

7.创建普通用户账号密码等

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

use osr_web # 切换数据库，有则切换，没有则创建
# 创建数据库关联的用户名和密码，以及读写权限等
db.createUser({
  user: 'root',
  pwd: 'root',
  roles:[{
    role: 'readWrite',
    db: 'osr_web'
  }]
})

8.可以使用软件Navicat Premium 12连接查看
