一、安装MongoDB
1.环境配置:
i.操作系统:CentOS release 6.8 (Final)
[root@iZ2ze2pbbffhmn53ao4tuaZ bin]# cat /etc/redhat-release
ii.计算机类型:x86_64
[root@iZ2ze2pbbffhmn53ao4tuaZ bin]# uname -m
2.下载对应的MongoDB 版本
[root@iZ2ze2pbbffhmn53ao4tuaZ bin]# wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.6.4.tgz
3.解压MongoDB 数据库
[root@iZ2ze2pbbffhmn53ao4tuaZ opt]# tar -zxvf mongodb-linux-x86_64-rhel62-3.6.4.tgz
4. 启动MongoDB
[root@iZ2ze2pbbffhmn53ao4tuaZ bin]# mkdir -p /data/db # 创建数据库数据存放目录
[root@iZ2ze2pbbffhmn53ao4tuaZ opt]# cd /opt/mongodb/bin
[root@iZ2ze2pbbffhmn53ao4tuaZ bin]# ./mongod # 启动Mongo Server服务,默认端口:27017,默认允许本地连接
二、配置账号和密码
1.开启认证
MongoDB 默认安装完成以后,只允许本地连接,同时不需要使用任何账号密码就可以直接连接MongoDB,这样就容易被黑,让支付一些比特币,所以为了避免这些不
必要的麻烦,所以我们需要给Mongo设置一个账号密码;
[root@iZ2ze2pbbffhmn53ao4tuaZ bin]# ./mongod --auth # 启用认证
2.创建管理员用户
> use admin switched to db admin > db.createUser({user:"admin",pwd:"password",roles:["root"]}) Successfully added user: { "user" : "admin", "roles" : [ "root" ] }
3.认证登录
> db.auth("admin", "password")
4.MongoDB role 类型
read:授予User只读数据的权限
readWrite:授予User读写数据的权限
dbAdmin:在当前dB中执行管理操作
dbOwner:在当前DB中执行任意操作
userAdmin:在当前DB中管理User
backup
restore
readAnyDatabase:授予在所有数据库上读取数据的权限
readWriteAnyDatabase:授予在所有数据库上读写数据的权限
userAdminAnyDatabase:授予在所有数据库上管理User的权限
dbAdminAnyDatabase:授予管理所有数据库的权限
clusterAdmin:授予管理集群的最高权限
clusterManager:授予管理和监控集群的权限,A user with this role can access the config and local databases, which are used in sharding and replication, respectively.
clusterMonitor:授予监控集群的权限,对监控工具具有readonly的权限
hostManager:管理Server
5.添加数据库用户
> use flowpp switched to db flowpp > db.createUser({user: "flowpp", pwd: "flopww", roles: [{ role: "dbOwner", db: "flowpp" }]}) # 创建用户flowpp,设置密码flopww,设置角色dbOwner
6.查看系统用户
> use admin switched to db admin > db.system.users.find() # 显示当前系统用户 { "_id" : "admin.admin", "user" : "admin", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "9jXmylyRAK22TZmzv1Thig==", "storedKey" : "z76cVrBjX/CTFmn5RujtU+dz7Nw=", "serverKey" : "JQGonM84iDMI1nIXW7FdyOE55ig=" } }, "roles" : [ { "role" : "root", "db" : "admin" } ] } { "_id" : "flowpp.flowpp", "user" : "flowpp", "db" : "flowpp", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "KvocqWZA9E2tXBHpKpdAeQ==", "storedKey" : "50Kxc3LEgCSVN1z16S8g4A6jVp8=", "serverKey" : "0RSnsxd/7Yzmqro/YOHf/kfbHCk=" } }, "roles" : [ { "role" : "dbOwner", "db" : "flowpp" } ] }
7.删除用户
1.切换admin ,删除用户flowpp ,删除失败
> use admin switched to db admin > db.dropUser("flowpp") false
2.切换flowpp ,删除用户flowpp,删除成功 > use flowpp switched to db flowpp > db.dropUser("flowpp") true
