前言：

现时小伙伴们对“apache24配置mongodb”大约比较注意，各位老铁们都需要了解一些“apache24配置mongodb”的相关文章。那么小编在网络上汇集了一些对于“apache24配置mongodb””的相关内容，希望看官们能喜欢，我们一起来了解一下吧！

配置yum源3.2 或3.4

vi /etc/yum.repos.d/mongodb-org-3.4.repo[mongodb-org-3.4]   name=MongoDB Repository    baseurl=    gpgcheck=1    enabled=1    gpgkey=从阿里源下载vi /etc/yum.repos.d/mongodb-org-3.2.0.repo[mongodb-org]name=MongoDB Repositorybaseurl=[MongoDB]name=MongoDB Repositorybaseurl=

wget下载

wget

安装

rpm -ivh mongodb-org-3.2.20-1.el7.x86_64.rpm         mongodb-org-server-3.2.20-1.el7.x86_64.rpm  mongodb-org-tools-3.2.20-1.el7.x86_64.rpmmongodb-org-mongos-3.2.20-1.el7.x86_64.rpm  mongodb-org-shell-3.2.20-1.el7.x86_64.rpm

安装前yum update

安装mongodbyum -y install mongodb-org mongodb-org-server

创建文件夹和权限

mkdir -pv /app/mongodb/{logs,data}chown   mongod:mongod /app/mongodb/*

修改配置在vi /etc/mongod.conf

systemLog:    quiet: false    path: /app/mongodb/logs/mongod.log    #path: /var/log/mongodb/mongod.log    logAppend: false    destination: fileprocessManagement:    fork: true    #pidFilePath: /app/mongodb/logs/mongodb.pid    pidFilePath: /var/run/mongodb/mongod.pidnet:    bindIp: 127.0.0.1    port: 27099    maxIncomingConnections: 65536    wireObjectCheck: true    ipv6: false storage:    dbPath: /app/mongodb/data    indexBuildRetry: true    journal:        enabled: true    directoryPerDB: false    engine: mmapv1    syncPeriodSecs: 60     mmapv1:        quota:            enforced: false            maxFilesPerDB: 8        smallFiles: true            journal:            commitIntervalMs: 100    wiredTiger:        engineConfig:            cacheSizeGB: 8            journalCompressor: snappy            directoryForIndexes: false          collectionConfig:            blockCompressor: snappy        indexConfig:            prefixCompression: trueoperationProfiling:    slowOpThresholdMs: 100    mode: off

mongodb 3.2 用户权限管理配置

用户权限设置1、进入mongodb的shell ： mongo2、切换数据库： use admin从3.0 版本起，默认只有 local 库，没有admin 库，需要我们自己来创建。3、添加用户，指定用户的角色和数据库：

db.createUser(

{ user: "admin",

customData：{description:"superuser"},

pwd: "admin",

roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]

}

)

user字段，为新用户的名字；pwd字段，用户的密码；cusomData字段，为任意内容，例如可以为用户全名介绍；roles字段，指定用户的角色，可以用一个空数组给新用户设定空角色。在roles字段,可以指定内置角色和用户定义的角色。

4、查看创建的用户 ： show users 或 db.system.users.find()5、启用用户权限：修改配置文件，增加配置：security:  authorization: enabled重新启动mongodb

6、用户验证使用：启用用户验证后，再次登录mongo shell ，执行 show dbs 等命令会提示“没有权限”。此时，需要用户验证登录。db.auth("admin","admin")

###创建普通用户use foo;db.createUser({user: 'foo', pwd: 'bar', roles: [{role: 'readWrite', db: 'foo'}]})db.auth('foo', 'bar')

其他内建的角色数据库用户角色：read、readWrite;数据库管理角色：dbAdmin、dbOwner、userAdmin；集群管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager；备份恢复角色：backup、restore；所有数据库角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase超级用户角色：root// 这里还有几个角色间接或直接提供了系统超级用户的访问（dbOwner 、userAdmin、userAdminAnyDatabase）内部角色：__system
