关于mongodb:Linux-Centos-7安装MongoDB

配置 yum 源

创立并编辑文件 /etc/yum.repos.d/mongodb-org-4.2.repo，填入以下内容：

[mongodb-org-4.2]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.2/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.2.asc

字段阐明:

name         # 名称
baseurl      # 取得下载的门路
gpkcheck=1   # 示意对从这个源下载的 rpm 包进行校验；enable=1     # 示意启用这个源。gpgkey       # gpg 验证 

应用 yum 装置 MongoDB

yum install -y mongodb-org

验证装置后果

rpm -qa |grep mongodb
rpm -ql mongodb-org-server

启动 MongoDB

service mongod start   或者  systemctl start mongod.service   // 启动
service mongod restart   // 重启
service mongod stop    // 敞开

sudo yum erase $(rpm -qa | grep mongodb-org)    # 卸载 MongoDB
sudo rm -r /var/log/mongodb  # 删除日志文件
sudo rm -r /var/lib/mongo    # 删除数据文件

批改配置文件 mongodb.conf

vi /etc/mongod.conf

# 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.

重启

service mongod restart 

近程连贯

mongo ip:27017

连贯到自定义的用户

创立用户，设置账号，明码，权限

// admin 数据库
> use admin
switched to db admin
> db.createUser({user:"root", pwd:"123456", roles:["root"] })
Successfully added user: {"user" : "root", "roles" : [ "root"] }

// 其余数据库
> use test
switched to db test
> db.createUser({user:"admin", pwd:"123456", roles:["readWrite", "dbAdmin"] })
Successfully added user: {"user" : "root", "roles" : [ "root"] }

批改 mongodb.conf 文件，启用身份验证

vi /etc/mongod.conf

security:
  authorization: "enabled"   # disable or enabled

重启 MongoDB

service mongod restart 

用户认证

> use admin
switched to db admin
> db.auth("root", "123456")
1 // 受权胜利 

近程连贯

// 终端连贯
mongo ip:27017/database -u username -p password

// mongoose 形式连贯
mongoose.connect('mongodb://username:password@host:port/database?options...', {useNewUrlParser: true});
