Mongo基本操作

#创建超级管理员 super
db.createUser(
{ user: "super",
    pwd: "super",
    roles: [ { role: "dbAdminAnyDatabase", db: "wb" } ]
}
);

#创建读写管理员 super_write
db.createUser(
{ user: "super",
    pwd: "super",
    roles: [ { role: "dbAdminAnyDatabase", db: "admin" } ]
}
);

#创建用户管理员 userAdmin
db.createUser(
{ user: "userAdmin",
    pwd: "userAdmin",
    roles: [ { role: "readWriteAnyDatabase", db: "admin" } ]
}
);


#创建普通用户 readWrite
db.createUser(
{ user: "readWrite",
    pwd: "readWrite",
    roles: [ { role: "readWrite", db: "gxpt" } ]
}
);

---------------------------------------------------------------------

---------------------------------------------------------------------
生成key file ok

openssl rand -base64 100 > /opt/var/data/mongodb/mongodb.key

---------------------------------------------------------------------
创建用户 ok
db.createUser(
{
user:"gxpt",
pwd:"gxpt",
roles:[{role:"readWrite",db:"gxpt"}]
}
)

db.createUser(
{
    user: "super1",
    pwd: "super1",
    roles: [ { role: "dbAdminAnyDatabase", db: "admin" }, "readWriteAnyDatabase" ]
}
)

db.createUser(
{
    user: "super123",
    pwd: "super123",
    roles: [ { role: "root", db: "admin" }, "root" ]
}
)

#创建超级管理员 super
db.createUser(
{ user: "root",
    pwd: "root",
    roles: [ { role: "root", db: "admin" } ]
}
);

#创建超级管理员 super
db.createUser(
{ user: "super",
    pwd: "super",
    roles: [ { role: "dbAdminAnyDatabase", db: "admin" } ]
}
);

#创建应用管理员 gxpt
db.createUser(
{ user: "gxpt",
    pwd: "gxpt",
    roles: [ { role: "readWrite", db: "gxpt" } ]
}
);

#创建用户管理员 userAdmin
db.createUser(
{ user: "userAdmin",
    pwd: "userAdmin",
    roles: [ { role: "readWriteAnyDatabase", db: "admin" } ]
}
);


#创建普通用户 readWrite
db.createUser(
{ user: "readWrite123",
    pwd: "readWrite123",
    roles: [ { role: "readWrite", db: "gxpt" } ]
}
);

认证用户
RS1:PRIMARY> db.auth("root","root");
1

RS1:PRIMARY> db.auth("gxpt","gxpt");
1

删除用户（必须到用户所属的db中执行删除操作）
RS1:PRIMARY> db.system.users.remove({user:"gxpt"})db.system.users.remove({user:"userAdmin"})
WriteResult({ "nRemoved" : 1 })
RS1:PRIMARY> db.system.users.remove({user:"read_write"})db.system.users.remove({user:"read_write"})
WriteResult({ "nRemoved" : 1 })
RS1:PRIMARY> db.system.users.remove({user:"gxpt"})db.system.users.remove({user:"super1"})
WriteResult({ "nRemoved" : 1 })

切换到gxpt数据库删除用户gxpt
use gxpt
RS1:PRIMARY> db.dropUser("gxpt", {w: "majority", wtimeout: 5000})db.dropUser("gxpt", {w: "majority", wtimeout: 5000})
true
---------------------------------------------------------------
认证用户 ok
db.auth("root", "root");
db.auth("test", "123456");
---------------------------------------------------------------

db.grantRolesToUser("super", [ { role: "read", db: "admin" } ]);

db.grantRolesToUser( "test" , [ { role: "dbOwner", db: "wb" } ])

---------------------------------------------------------------
远程登录示例 ok

mongo -usuper -psuper 192.168.8.236/admin
mongo -ugxpt -pgxpt 192.168.8.236/gxpt

mongo -usuper -psuper 192.168.8.237/admin
mongo -ugxpt -pgxpt 192.168.8.237/gxpt
---------------------------------------------------------------
在SECONDARY查询出发现如下错误：

SECONDARY> show collections;
    Sat Aug 4 15:29:00 uncaught exception: error: { "$err" : "not master and slaveok=false", "code" : 13435 }

这是正常的，因为SECONDARY是不允许读写的，如果非要解决，方法如下：

SECONDARY> rs.slaveOk();

---------------------------------------------------------------
-安全关闭数据库 ok

> use admin;                     -
RS1:PRIMARY> use admin;
switched to db admin
RS1:PRIMARY> db.auth("root", "root");
1
RS1:PRIMARY> db.shutdownServer();
