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 Repositorybaseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.2/x86_64/gpgcheck=1enabled=1gpgkey=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 mongodbrpm -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MongoDBsudo 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 interfacesnet: 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 adminswitched to db admin> db.createUser({ user:"root", pwd:"123456", roles:["root"] })Successfully added user: { "user" : "root", "roles" : [ "root" ] }// 其余数据库> use testswitched 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.confsecurity: authorization: "enabled" # disable or enabled重启MongoDB
service mongod restart 用户认证
> use adminswitched 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});
