| 导读 | mongodb 3.0 访问控制改了很多，需要你老老实实的去看文档去验证，谷歌百度出来的多半就是错误的。 还需要注意这个参数authenticationmechanisms。 |
为了兼用2.6版本，我直接指定下面的参数：
setparameter: authenticationmechanisms: mongodb-cr
下面看看如何创建访问控制权限
不使用 —auth 参数，启动 mongodb
mongodb-linux-i686-3.0.0/bin/mongod -f mongodb-linux-i686-3.0.0/mongodb.conf
此时你 show dbs 会看到只有一个local数据库，那个所谓的*****是不存在的。
mongodb 没有超级无敌用户root，只有能管理用户的用户 user*****anydatabase。
use *****
db.createuser(
{
user: "buru",
pwd: "12345678",
roles: [ { role: "user*****anydatabase", db: "*****" } ]
}
)
roles 中的 db 参数是必须的，不然会报错：error: couldn’t add user: missing expected field “db”。另外，有很多文章记录的是使用 db.adduser(…) 方法，这个方法是旧版的，3.0中已经不存在，详见：http://docs.mongodb.org/manual/reference/method/js-user-management。
切换到*****下，查看刚才创建的用户：
show users
或
db.system.users.find()
{ "_id" : "*****.buru", "user" : "buru", "db" : "*****", "credentials" : { "scram-sha-1" : { "iterationcount" : 10000, "salt" : "gwvwua/dxvxgshavenlyva==", "storedkey" : "l2qevteujpkcuqdekqfiwbsv4ms=", "serverkey" : "m1ofnkxg2sncsfrbjbx4pxbsgvg=" } }, "roles" : [ { "role" : "user*****anydatabase", "db" : "*****" } ] }
怎么关闭 mongodb？千万不要 kill -9 pid，可以 kill -2 pid 或 db.shutdownserver()
下面使用 —auth 参 数，重新启动 mongodb：
mongodb-linux-i686-3.0.0/bin/mongod --auth -f mongodb-linux-i686-3.0.0/mongodb.conf
mongodb-linux-i686-3.0.0/bin/mongo
use *****
db.auth("buru","12345678") #认证，返回1表示成功
或
mongodb-linux-i686-3.0.0/bin/mongo -u buru -p 12345678 --authenticationdatabase *****
此时?show collections 报错
2015-03-17t10:15:56.011 0800 e query error: listcollections failed: {

"errmsg" : "not authorized on ***** to execute command { listcollections: 1.0 }",

因为，用户buru只有用户管理的权限。
下面创建用户，用户都跟着库走，创建的用户都是
use tianhe
db.createuser(
{
user: "bao",
pwd: "12345678",
roles: [
{ role: "readwrite", db: "tianhe" },
{ role: "read", db: "tianhe2" }
]
}
)
查看刚刚创建的用户。
show users
{
"_id" : "tianhe.bao",
"user" : "bao",
"db" : "tianhe",
"roles" : [
{
"role" : "readwrite",
"db" : "tianhe"
},
{
"role" : "read",
"db" : "tianhe2"
}
]
}
查看整个mongodb全部的用户：
use *****
db.system.users.find()
{ "_id" : "*****.buru", "user" : "buru", "db" : "*****", "credentials" : { "scram-sha-1" : { "iterationcount" : 10000, "salt" : "gwvwua/dxvxgshavenlyva==", "storedkey" : "l2qevteujpkcuqdekqfiwbsv4ms=", "serverkey" : "m1ofnkxg2sncsfrbjbx4pxbsgvg=" } }, "roles" : [ { "role" : "user*****anydatabase", "db" : "*****" } ] }
{ "_id" : "tianhe.bao", "user" : "bao", "db" : "tianhe", "credentials" : { "scram-sha-1" : { "iterationcount" : 10000, "salt" : "//xy1v1fbqehc1gzqqzhgq==", "storedkey" : "zs/o54zzl/fdcxlqj98kdavtff0=", "serverkey" : "iipnyz2g**khyk3zgz6mubt0pi4=" } }, "roles" : [ { "role" : "readwrite", "db" : "tianhe" }, { "role" : "read", "db" : "tianhe2" } ] }
创建完毕，验证一下：
use buru
show collections
2015-03-17t10:30:06.461 0800 e query error: listcollections failed: {
"ok" : 0,
"errmsg" : "not authorized on buru to execute command { listcollections: 1.0 }",
"code" : 13
}
at error ()
at db._getcollectioninfoscommand (src/mongo/shell/db.js:643:15)
at db.getcollectioninfos (src/mongo/shell/db.js:655:20)
at db.getcollectionnames (src/mongo/shell/db.js:666:17)

显然没权限，先auth：
db.auth("bao","12345678")
show collections
