MongoDB 设置账号和密码
<p>https://www.cnblogs.com/mengyu/p/9071371.html</p><p> </p>
<p>一、安装MongoDB</p>
<p> 1.环境配置：</p>
<p> i.操作系统：CentOS release 6.8 (Final) </p>
<div class="cnblogs_code">
<pre># cat /etc/redhat-release</pre>
</div>
<p> ii.计算机类型：x86_64</p>
<div class="cnblogs_code">
<pre># uname -m</pre>
</div>
<p> 2.下载对应的MongoDB 版本</p>
<div class="cnblogs_code">
<pre># wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.6.4.tgz</pre>
</div>
<p> 3.解压MongoDB 数据库</p>
<div class="cnblogs_code">
<pre># tar -zxvf mongodb-linux-x86_64-rhel62-3.6.4.tgz</pre>
</div>
<p> 4. 启动MongoDB</p>
<div class="cnblogs_code">
<pre># mkdir -p /data/db # 创建数据库数据存放目录</pre>
<pre># cd /opt/mongodb/bin<br data-filtered="filtered"><br data-filtered="filtered"># ./mongod# 启动Mongo Server服务，默认端口:27017，默认允许本地连接</pre>
</div>
<p>二、配置账号和密码</p>
<p> 1.开启认证</p>
<p> 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</p>
<p>必要的麻烦，所以我们需要给Mongo设置一个账号密码；</p>
<div class="cnblogs_code">
<pre># ./mongod --auth# 启用认证</pre>
</div>
<p> 2.创建管理员用户</p>
<div class="cnblogs_code">
<pre>> use admin
switched to db admin
> db.createUser({user:"admin",pwd:"password",roles:["root"]})
Successfully added user: { "user" : "admin", "roles" : [ "root" ] }</pre>
</div>
<p> 3.认证登录</p>
<div class="cnblogs_code">
<pre>> db.auth("admin", "password")</pre>
</div>
<p> 4.MongoDB role 类型</p>
<ul>
<li>数据库用户角色（Database User Roles）</li>
</ul>
<p> read：授予User只读数据的权限<br data-filtered="filtered"> readWrite：授予User读写数据的权限</p>
<ul>
<li>数据库管理角色（Database Administration Roles）：</li>
</ul>
<p> dbAdmin：在当前dB中执行管理操作<br data-filtered="filtered"> dbOwner：在当前DB中执行任意操作<br data-filtered="filtered"> userAdmin：在当前DB中管理User</p>
<ul>
<li>备份和还原角色（Backup and Restoration Roles）：</li>
</ul>
<p> backup<br data-filtered="filtered"> restore</p>
<ul>
<li>跨库角色（All-Database Roles）：</li>
</ul>
<p> readAnyDatabase：授予在所有数据库上读取数据的权限<br data-filtered="filtered"> readWriteAnyDatabase：授予在所有数据库上读写数据的权限<br data-filtered="filtered"> userAdminAnyDatabase：授予在所有数据库上管理User的权限<br data-filtered="filtered"> dbAdminAnyDatabase：授予管理所有数据库的权限</p>
<ul>
<li>集群管理角色（Cluster Administration Roles）：</li>
</ul>
<p> clusterAdmin：授予管理集群的最高权限<br data-filtered="filtered"> 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.<br data-filtered="filtered"> clusterMonitor：授予监控集群的权限，对监控工具具有readonly的权限<br data-filtered="filtered"> hostManager：管理Server</p>
<p> 5.添加数据库用户</p>
<div class="cnblogs_code">
<pre>> 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</pre>
</div>
<p> 6.查看系统用户</p>
<div class="cnblogs_code">
<div class="cnblogs_code_toolbar"><span class="cnblogs_code_copy"><img src="https://common.cnblogs.com/images/copycode.gif"></span></div>
<pre>> 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" } ] }</pre>
<div class="cnblogs_code_toolbar"><span class="cnblogs_code_copy"><img src="https://common.cnblogs.com/images/copycode.gif"></span></div>
</div>
<p> 7.删除用户</p>
<div class="cnblogs_code">
<div class="cnblogs_code_toolbar"><span class="cnblogs_code_copy"><img src="https://common.cnblogs.com/images/copycode.gif"></span></div>
<pre>1.切换admin ，删除用户flowpp ，删除失败<br data-filtered="filtered">> use admin
switched to db admin
> db.dropUser("flowpp")
false<br data-filtered="filtered">2.切换flowpp ，删除用户flowpp，删除成功
> use flowpp
