MongoDB默认是不认证的，默认没有账号，只要能连接上服务就可以对数据库进行各种操作，MongoDB认为安全最好的方法就是在一个可信的环境中运行它，保证之后可信的机器才能访问它，可能这些对一些要求高的环境，安全还不够。MongoDB提供用户认证，需要在启动时加上--auth开启认证。

一、MongoDB安装

代码语言：javascript
复制
Mongodb下载地址：https://pan.baidu.com/s/194ef261BpcypxzAl9aRaQg
提取密码：tv8m
下载放到服务器的/usr/local/src目录下

1.1）安装MongoDB
[root@MongoDB-server ~]# cd /usr/local/src/
[root@MongoDB-server src]# ll mongodb-linux-x86_64-rhel62-v3.2-latest.tgz 
-rw-r--r-- 1 root root 86699142 Nov 22  2017 mongodb-linux-x86_64-rhel62-v3.2-latest.tgz
[root@MongoDB-server src]# tar -zvxf mongodb-linux-x86_64-rhel62-v3.2-latest.tgz 
[root@MongoDB-server src]# mv mongodb-linux-x86_64-rhel62-3.2.17-34-g4c1bae566c /usr/local/mongodb

[root@MongoDB-server src]# ll /usr/local/mongodb              //Mongodb主目录
total 100
drwxr-xr-x 2 root root  4096 Sep 20 22:33 bin
-rw-r--r-- 1 root root 34520 Nov 21  2017 GNU-AGPL-3.0
-rw-r--r-- 1 root root 16726 Nov 21  2017 MPL-2
-rw-r--r-- 1 root root  2262 Nov 21  2017 README
-rw-r--r-- 1 root root 35910 Nov 21  2017 THIRD-PARTY-NOTICES

[root@MongoDB-server src]# mkdir /usr/local/mongodb/data     //Mongodb数据目录，可以存放在一个独立的大分区上
[root@MongoDB-server src]# mkdir /usr/local/mongodb/log      //Mongodb日志目录

1.2）启动MongoDB
使用mongod命令建立一个mongodb数据库链接，数据库的路径为/usr/local/mongodb/data，日志路径为/usr/local/mongodb/log/mogodb.log
mongodb的启动程序放在后台执行，下面命令执行后，按ctrl＋c。
[root@MongoDB-server src]# nohup /usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data/ --logpath=/usr/local/mongodb/log/mongo.log &

==========================================
mongodb的参数说明：
--dbpath 数据库路径(数据文件)
--logpath 日志文件路径
--master 指定为主机器
--slave 指定为从机器
--source 指定主机器的IP地址
--pologSize 指定日志文件大小不超过64M.因为resync是非常操作量大且耗时，最好通过设置一个足够大的oplogSize来避免resync(默认的 oplog大小是空闲磁盘大小的5%)。
--logappend 日志文件末尾添加
--port 启用端口号
--fork 在后台运行
--only 指定只复制哪一个数据库
--slavedelay 指从复制检测的时间间隔
--auth 是否需要验证权限登录(用户名和密码)
==========================================

[root@MongoDB-server src]# ps -ef|grep mongodb
root     13216 10204  0 22:38 pts/1    00:00:00 /usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data/ --logpath=/usr/local/mongodb/log/mongo.log
root     14185 10204  0 22:42 pts/1    00:00:00 grep mongodb

MongoDB默认端口是27017，启动后，等一会儿端口就会起来。如果启动后，发现端口没有起来，可以查看日志/usr/local/mongodb/log/mongo.log
[root@MongoDB-server src]# lsof -i:27017
COMMAND   PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
mongod  13216 root    6u  IPv4 4260453      0t0  TCP *:27017 (LISTEN)

1.3）设置mongodb的环境变量
[root@MongoDB-server src]# vim /etc/profile
......
export PATH=$PATH:/usr/local/mongodb/bin/
[root@MongoDB-server src]# source /etc/profile
[root@MongoDB-server src]# mongod --version
db version v3.2.17-34-g4c1bae566c
git version: 4c1bae566c0c00f996a2feb16febf84936ecaf6f
OpenSSL version: OpenSSL 1.0.1e-fips 11 Feb 2013
allocator: tcmalloc
modules: none
build environment:
    distmod: rhel62
    distarch: x86_64
    target_arch: x86_64

1.4）为了更方便的启动和关闭MongoDB，可以使用Shell写脚本，当然也可以加入到service中。更好的方式是采用配置文件，把MongoDB需要的参数写入配置文件，
然后在脚本中引用；
[root@MongoDB-server src]# vim /usr/local/mongodb/mongodb.conf
#代表端口号，如果不指定则默认为27017
port=27017
#绑定ip
bind_ip=0.0.0.0
#MongoDB数据文件目录
dbpath=/usr/local/mongodb/data
#MongoDB日志文件目录
logpath=/usr/local/mongodb/log/mongo.log
#日志文件自动累加
logappend=true

编写MongoDB启动脚本
[root@MongoDB-server src]# vim /etc/init.d/mongodb
#!/bin/bash
#
# mongod        Start up the MongoDB server daemon
#
   
# source function library
. /etc/rc.d/init.d/functions
#定义命令
CMD=/usr/local/mongodb/bin/mongod
#定义配置文件路径
INITFILE=/usr/local/mongodb/mongodb.conf
start()
{
    #&表示后台启动，也可以使用fork参数
    $CMD -f $INITFILE &
    echo "MongoDB is running background..."
}
   
stop()
{
    pkill mongod
    echo "MongoDB is stopped."
}
   
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    *)
        echo $"Usage: $0 {start|stop}"
esac

授予脚本可执行权限
[root@MongoDB-server src]# chmod 755 /etc/init.d/mongodb

[root@MongoDB-server src]# /etc/init.d/mongodb status
Usage: /etc/init.d/mongodb {start|stop}
[root@MongoDB-server src]# /etc/init.d/mongodb stop
Terminated
[root@MongoDB-server src]# lsof -i:27001
[1]+  Done                    nohup /usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data/ --logpath=/usr/local/mongodb/log/mongo.log
[root@MongoDB-server src]# lsof -i:27001
[root@MongoDB-server src]# /etc/init.d/mongodb start
MongoDB is running background...
[root@MongoDB-server src]# ps -ef|grep mongodb
root     16060     1  2 22:49 pts/1    00:00:00 /usr/local/mongodb/bin/mongod -f /usr/local/mongodb/mongodb.conf
root     16205 10204  0 22:49 pts/1    00:00:00 grep mongodb

[root@MongoDB-server ~]# lsof -i:27001
[root@MongoDB-server ~]# 

启动后发现27017端口没有起来，查看日志：
[root@MongoDB-server src]# tail -f /usr/local/mongodb/log/mongo.log
......
2018-09-20T22:55:46.236+0800 I NETWORK  [initandlisten] waiting for connections on port 27017
2018-09-20T22:55:46.290+0800 W NETWORK  [HostnameCanonicalizationWorker] Failed to obtain address information for hostname MongoDB-server: Name or service not known

原因：获取不到地址对应的主机名，这一般与HOSTS有关

解决办法：
[root@MongoDB-server ~]# ifconfig|grep "inet addr"|grep Bcast|awk -F":" '{print $2}'|awk '{print $1}'
192.168.10.205
[root@MongoDB-server ~]# hostname 
MongoDB-server
[root@MongoDB-server ~]# vim /etc/hosts
[root@MongoDB-server ~]# echo "192.168.10.205 MongoDB-server" >> /etc/hosts
[root@MongoDB-server ~]# cat /etc/hosts
......
192.168.10.205 MongoDB-server

再次启动
[root@MongoDB-server ~]# ps -ef|grep mongodb
root     17789     1  0 22:55 pts/0    00:00:01 /usr/local/mongodb/bin/mongod -f /usr/local/mongodb/mongodb.conf
root     18933 16606  0 23:00 pts/0    00:00:00 grep mongodb

[root@MongoDB-server ~]# ps -ef|grep mongodb
root     18979 16606  0 23:00 pts/0    00:00:00 grep mongodb
[root@MongoDB-server ~]# /etc/init.d/mongodb start
MongoDB is running background...

[root@MongoDB-server ~]# ps -ef|grep mongodb
root     17789     1  0 22:55 pts/0    00:00:01 /usr/local/mongodb/bin/mongod -f /usr/local/mongodb/mongodb.conf
root     19132 16606  0 23:00 pts/0    00:00:00 grep mongodb
[root@MongoDB-server ~]# lsof -i:27017
COMMAND   PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
mongod  17789 root    6u  IPv4 4289555      0t0  TCP *:27017 (LISTEN)

连接MongoDB服务
[root@MongoDB-server src]# mongo 127.0.0.1:27017    或者直接使用mongo命令进行连接，默认连接的就是127.0.0.1:27017

二、MongoDB认证

MongoDB Roles（内置角色） - 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

具体角色 - Read：允许用户读取指定数据库 - readWrite：允许用户读写指定数据库 - dbAdmin：允许用户在指定数据库中执行管理函数，如索引创建、删除，查看统计或访问system.profile - userAdmin：允许用户向system.users集合写入，可以找指定数据库里创建、删除和管理用户 - clusterAdmin：只在admin数据库中可用，赋予用户所有分片和复制集相关函数的管理权限。 - readAnyDatabase：只在admin数据库中可用，赋予用户所有数据库的读权限 - readWriteAnyDatabase：只在admin数据库中可用，赋予用户所有数据库的读写权限 - userAdminAnyDatabase：只在admin数据库中可用，赋予用户所有数据库的userAdmin权限 - dbAdminAnyDatabase：只在admin数据库中可用，赋予用户所有数据库的dbAdmin权限。 - root：只在admin数据库中可用。超级账号，超级权限

代码语言：javascript
复制
MongoDB认证前需要添加账号,添加管理员账号(默认情况下系统中没有用户)

谨记：先在不开启认证的情况下，创建用户，之后关闭服务，然后再开启认证，才生效！！！！

[root@MongoDB-server src]# mongo 127.0.0.1:27017
......

切换到admin库
> use admin                         
switched to db admin

添加超级用户
> db.system.users.find();           
> db.addUser("admin","1234!@#$qwer")    
2018-09-20T23:12:10.968+0800 E QUERY    [thread1] TypeError: db.addUser is not a function :
@(shell):1:1

如上创建用户报错：报错addUser is not a function
经过排查原因，由于MongDB3.x版本已经不再支持addUser()方法，用createUser()方法取而代之。
> db.createUser({user: "admin",pwd: "1234!@#$qwer",roles: [ "readWrite", "dbAdmin" ]})
Successfully added user: { "user" : "admin", "roles" : [ "readWrite", "dbAdmin" ] }

查询添加的用户
>  db.system.users.find();
{ "_id" : "admin.admin", "user" : "admin", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : 
"TzPswYhGHMhnb18ccP41Hw==", "storedKey" : "MFNZp6CAAzd+XYi9hv1EQm6jHdU=", "serverKey" : "s1nHp0XO19IgIsd//wXc22ukaAY=" } }, "roles" 
: [ { "role" : "readWrite", "db" : "admin" }, { "role" : "dbAdmin", "db" : "admin" } ] }

添加普通账号
切换到kevin库添加普通用户（readWrite有读写权限；read有读权限）
> use kevin;
switched to db kevin
> db.createUser({user: "bobo",pwd: "bobo@123",roles: [ "dbOwner" ]});
Successfully added user: { "user" : "bobo", "roles" : [ "dbOwner" ] }
> db.createUser({user: "shibo",pwd: "shibo@123",roles: [ "read" ]});
Successfully added user: { "user" : "shibo", "roles" : [ "read" ] }

查询刚刚添加的所有用户：
> use admin;
switched to db admin
> db.system.users.find();
{ "_id" : "admin.admin", "user" : "admin", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "TzPswYhGHMhnb18ccP41Hw==", "storedKey" : "MFNZp6CAAzd+XYi9hv1EQm6jHdU=", "serverKey" : "s1nHp0XO19IgIsd//wXc22ukaAY=" } }, "roles" : [ { "role" : "readWrite", "db" : "admin" }, { "role" : "dbAdmin", "db" : "admin" } ] }
{ "_id" : "kevin.bobo", "user" : "bobo", "db" : "kevin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "cuv5jNwgZJygGFLtjD/Mjw==", "storedKey" : "OqJ25tCFO/+VTcKiKNCIHNivLEs=", "serverKey" : "XVyASud0LDPREZ3EqM78bBtGomk=" } }, "roles" : [ { "role" : "dbOwner", "db" : "kevin" } ] }
{ "_id" : "kevin.shibo", "user" : "shibo", "db" : "kevin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "Y7HmwAIYs+OHETZO0V2yTg==", "storedKey" : "5OjRBikMkn2ns+pDCvn3FVc5RJE=", "serverKey" : "YYRypQKmZcpg07tT+4F5MBwqHJY=" } }, "roles" : [ { "role" : "read", "db" : "kevin" } ] }
> 

删除用户
> db.system.users.remove({user:"admin"})
WriteResult({ "nRemoved" : 1 })
> db.system.users.remove({user:"shibo"})
WriteResult({ "nRemoved" : 1 })
> db.system.users.remove({user:"bobo"});
WriteResult({ "nRemoved" : 1 })

再次查看
> db.system.users.find();
> 

再添加用户
> use admin
switched to db admin
> db.createUser({user: "admin",pwd: "admin2018",roles: [{role:"readWrite",db:"dbAdmin"}]})
Successfully added user: {
        "user" : "admin",
        "roles" : [
                {
                        "role" : "readWrite",
                        "db" : "dbAdmin"
                }
        ]
}

> use kevin
switched to db kevin
> db.createUser({user: "kevin",pwd: "shibo2018",roles: [{role:"readWrite",db:"kevin"}]});
Successfully added user: {
        "user" : "kevin",
        "roles" : [
                {
                        "role" : "readWrite",
                        "db" : "kevin"
                }
        ]
}

> use admin
switched to db admin
> db.system.users.find();
{ "_id" : "admin.admin", "user" : "admin", "db" : "admin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "ZT4lWai64T8GO7jSfxuWTA==", "storedKey" : "oscsyuNiSfOvjPZgzAcapyqJjdM=", "serverKey" : "HLGVVyKMXI96StrnrhngQl2jA10=" } }, "roles" : [ { "role" : "readWrite", "db" : "dbAdmin" } ] }
{ "_id" : "kevin.kevin", "user" : "kevin", "db" : "kevin", "credentials" : { "SCRAM-SHA-1" : { "iterationCount" : 10000, "salt" : "iwyUMHBs6QUc4htcjQxJag==", "storedKey" : "hWZ0CvjVEwMUSm5wKen8Sg9Ju1Q=", "serverKey" : "QRqigCFp5Ph1D+GpOJDvGiIGfj8=" } }, "roles" : [ { "role" : "readWrite", "db" : "kevin" } ] }
> 

修改用户密码，可以利用db.changeUserPassword进行密码重置！！！！！
> use shibo;
switched to db shibo
> db.changeUserPassword("shibo","bobo@19870709"); 

以--auth启动mongodb开启认证（或者在配置文件中添加"auth=true"）
[root@MongoDB-server ~]# vim /usr/local/mongodb/mongodb.conf
#代表端口号，如果不指定则默认为27017
port=27017
#绑定ip
bind_ip=0.0.0.0
#MongoDB数据文件目录
dbpath=/usr/local/mongodb/data
#MongoDB日志文件目录
logpath=/usr/local/mongodb/log/mongo.log
#日志文件自动累加
logappend=true
#开启MongoDB认证
auth=true             

[root@MongoDB-server ~]# cat /etc/init.d/mongodb 
......
    $CMD -f $INITFILE --auth &
......

重启mongodb
