参见：[https://docs.mongodb.com/v3.2/tutorial/manage-users-and-roles/][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

# [第一步下载    ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles] #

[MongoDB 提供了 linux 各发行版本 64 位的安装包，你可以在官网下载安装包。][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[下载地址：https://www.mongodb.com/download-center\#community][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[下载完安装包，并解压 tgz（以下演示的是 64 位 Linux上的安装） 。][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86\_64-3.0.6.tgz    \# 下载  
tar -zxvf mongodb-linux-x86\_64-3.0.6.tgz                                   \# 解压  
 ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

#    [第二步    ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles] #

[执行命令  export PATH=<mongodb-install-directory>/bin:$PATH][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[<mongodb-install-directory> 这个替换成你MongoDB的安装目录][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

# [第三步 创建数据目录    ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles] #

[ /data/mongodb  /data/mongodb/log  /data/mongodb/log/mongodb.log][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[db 和log 可以用 mkdir 命令 mkdir db   mongodb.log 用vi  mongodb.log 来创建  ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

# [第四步 创建mongodb.conf     ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles] #

[命令  vi /etc/mongodb.conf    ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[mongodb.conf内容][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[ ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

dbpath=/data/mongodb
    
    logpath=/data/mongodb/log/mongodb.log
    
    logappend=true
    
    port=27017
    
    fork=true
    
    dapath 是数据库路径  用上面建立的数据目录
    
    logpath 是日志目录
    
    logappend 采用日志追加的方式
    
    port  端口号
    
    fork  后台运行

# [第五步启动mongodb服务端    ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles] #

[./mongod -f /etc/mongodb.conf][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[如果系统提示找不到mongod 的话 cd到 mongodb 的bin目录下][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

# [第六步 启动mongodb客户端（不成功看下面）][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]     #

[新开一个命令窗口  执行下面的命令][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[ ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[<mongodb-install-directory>/bin/mongo][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

# [第七步 创建用户][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]     #

[ ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]use admin     (少了这一步，导致建的用户不是在这个数据库的下边）

[db.createUser(\{user:"root",pwd:"mima",roles:\[\{role:"readWriteAnyDatabase",db:"admin"\}\]\}) ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[可以看一下成功没][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[db.auth("用户名","密码")][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[返回  1成功0失败][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

# [第九步 停服务][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]     #

[1-8 都是无密码登录的  就是说连你的库不需要用户名密码 。可以脑补一下后果][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[在你连接客户端那个窗口 ctrl+c 就停了 ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[在执行一个 命令确保它停下来 ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[ mongod  --shutdown  --dbpath /usr/mongodb/data/db/][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[dbpath 后面那个换成你自己的 如果mongod 找不到 可以cd到<mongodb-install-directory>/bin这个目录][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[然后再搞执行一下 如果还是找不mongod 那就这个命令  ./mongod  --shutdown  --dbpath /usr/mongodb/data/db/][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[友情提示 停完之后 去dbpath 找到mongod.lock  删掉他][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

# [第十步修改mongodb.conf][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]     #

[ vi /etc/mongodb.conf    
然后新启一行加个 auth=true   
退出保存  ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[auth 是校验用户名密码 ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

# [第十一步 启动mongodb服务端（和第五步一样）][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]     #

方法一：

[搞完了 起一下 客户端 然后连一下数据库 看下就ok][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[use xxx    ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[xxx 是数据库名][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[ ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[db.xxx.insert(\{"name":"菜鸟教程"\})  
.xxx.insert(\{"name":"菜鸟教程"\})  
插的数据要不不显示 不让插 的话 就下面那句  ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[db.auth("用户名"，"密码")][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[然后  show dbs 查看你所有的数据库][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

方法二：

./mongo  --port 27017 -u "ttmongoadmin" -p "TyIiODS23YS3ru9p" --authenticationDatabase "admin"

[备注  
第五步和第六步不成功  
这么搞 ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[ ][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[1、删除mongo.lock文件][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[2、 ./mongod --repair  （修复连接）][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[3.   ./mongod -f /etc/mongodb.conf][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[第五步错（记得看一下你mongodb.conf里面的路径和你本地的是不是能对上）][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]

[第六步错][https_docs.mongodb.com_v3.2_tutorial_manage-users-and-roles]
