数据库相关说明 / 使用ubuntu 20 apt安装 MongoDB

1、安装MongoDB，打开终端，输入以下命令

root@vultr:~# sudo apt-get install mongodb Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: libboost-filesystem1.71.0 libboost-iostreams1.71.0 libboost-program-options1.71.0 libgoogle-perftools4 libpcrecpp0v5 libsnappy1v5 libtcmalloc-minimal4 libyaml-cpp0.6 mongo-tools mongodb-clients mongodb-server mongodb-server-core The following NEW packages will be installed: libboost-filesystem1.71.0 libboost-iostreams1.71.0 libboost-program-options1.71.0 libgoogle-perftools4 libpcrecpp0v5 libsnappy1v5 libtcmalloc-minimal4 libyaml-cpp0.6 mongo-tools mongodb mongodb-clients mongodb-server mongodb-server-core 0 upgraded, 13 newly installed, 0 to remove and 19 not upgraded.

2、装好以后应该会自动运行mongod程序，通过pgrep mongo -l 查看进程是否已经启动

root@vultr:/# pgrep mongo -l 68355 mongo 68944 mongod root@vultr:/#

3、在终端输入mongo，然后回车进入数据库，如果修改了默认端口，那么后面还要加上端口号，比如mongo --port 端口号

root@vultr:~# mongo MongoDB shell version v3.6.8 connecting to: mongodb://127.0.0.1:27017 Implicit session: session { "id" : UUID("472690cf-1b8d-4f71-aef5-b42ee91a030e") } MongoDB server version: 3.6.8 Welcome to the MongoDB shell. For interactive help, type "help". ......

创建一个超级管理员wgcloud

> db.createUser({user: "wgcloud",pwd: "wgcloud709!", roles: [ { role: "root", db: "admin" } ]}) Successfully added user: { "user" : "wgcloud", "roles" : [ { "role" : "root", "db" : "admin" } ] }

验证用户是否添加成功，如果返回1，则表示成功

> db.auth("wgcloud", "wgcloud709!") 1 >

4、修改默认端口和希望外网访问，vim /etc/mongodb.conf，或者vim /etc/mongod.conf

找到以下配置项，vim下按字母 i 输入进行文件修改

修改端口，修改port：27017，如修改成port: 37017

外网访问，修改为bind_ip：0.0.0.0

修改完成按Esc，再按Shift+:,然后输入“wq”,保存文件并退出，然后重启mongodb服务

bind_ip = 0.0.0.0 port = 27017

开启mongodb服务 sudo service mongodb start 停止mongodb服务 sudo service mongodb stop 重启mongodb服务 sudo service mongodb restart 使用“mongo --port 28017”进入mongo shell

好了，至此MongoDB就安装好了，默认端口是27017

MongoDB客户端工具使用
