mongo集群分片如何添加认证密码？
1.首先配置好集群
参考“重点实战mongodb3.0.5Relica Sets+sharding集群”
2.登录到其中一个monogs，然后添加一个用户
$ mongo 172.28.19.237:60005
use admin
db.createUser({ user: 'root', pwd:'123456', roles:['root']})
PS: 创建的用户root会同步到243和246mongos
测试
[mgousr03@mongodb-test1 ~]$ mongo -u root -p 123456 --host=172.28.19.237--port=60005 --authenticationDatabase admin mongo_test
MongoDB shell version: 3.0.5
connecting to:172.28.19.237:60005/mongo_test
3.在各个sharing分片添加用户
(1)在172.28.19.237:37017添加用户
use admin
db.createUser({ user: 'root', pwd:'123', roles:['root']})
(2)在172.28.19.237:37018添加用户
use admin
db.createUser({ user: 'root', pwd:'123', roles:['root']})
(3)在172.28.19.237:37019添加用户
use admin
db.createUser({ user: 'root', pwd:'123', roles:['root']})
4.配置参数修改
(1)在/data/users/mgousr03/mongodb/etc目录下生产一个keyFilers0.key文件
所有配置文件共有keyFilers0.key文件
生成如下key
echo"c57a012cf2f8a8e20dd4b21a7fae48b3" >/data/users/mgousr03/mongodb/etc/keyFilers0.key
然后将keyFilers0.keycopy到其他主机上即可。
600 权限
chmod 600 keyFilers0.key
(2)修改配置参数
在各个shard*.conf参数中添加如下(启用认证)
auth=true
keyFile=/data/users/mgousr03/mongodb/etc/keyFilers0.key
在各个节点config.conf参数中添加如下(启用认证)
auth=true
keyFile=/data/users/mgousr03/mongodb/etc/keyFilers0.key
在各个节点mongos.conf参数中添加如下(启用认证)
keyFile=/data/users/mgousr03/mongodb/etc/keyFilers0.key
该参数不支持auth=true参数
5.查询mongodb各个进行
[mgousr03@mongodb-test1 etc]$ ps -ef| grep mongo |grep mgousr03 | grep -v grep
mgousr03 1907 1 1 10:27 ? 00:00:40 mongod -f shard1_1.conf
mgousr03 2130 1 0 10:28 ? 00:00:10 mongod -f shard2_1.conf
mgousr03 2225 1 1 10:29 ? 00:00:33 mongod -f shard3_1.conf
mgousr03 2777 1 0 10:38 ? 00:00:08 mongod -f config.conf
mgousr03 2798 1 1 10:39 ? 00:00:23 mongos -f mongos.conf
使用kill-2 进行kill掉。
6.启动mongo进程
先启动sharing分片，然后在动config，再启动mongos进程。
*******测试********
连接到mongos
[mgousr03@mongodb-test1 ~]$ mongo172.28.19.237:60005
MongoDB shell version: 3.0.5
connecting to:172.28.19.237:60005/test

或者直接登录 mongo-u root -p 123456 --host=172.28.19.237 --port=60005 --authenticationDatabaseadmin mongo_test
创建数据库，集合并记载分片数据：
对集合进行分片(在chicago数据库中创建users集合)
mongos> use admin
switched to db admin
db.runCommand({"enablesharding":"wilson"})
mongos>db.runCommand({"shardcollection":"wilson.results","key":{user_id:"hashed"}})
use wilson
db.results.ensureIndex({user_id:"hashed"}, {background: true})
for(var i=1;i<=100000;i++)db.results.insert({"ip" : "192.168.168.254","g_roup": "kiwi","mac" :"of:fd:67:8c:2f:8f","address" :"hongmei1801num","user_id" : i,"name" :"user10000000","title" :"system","database" :"mongodb","telphone" :NumberLong("15718441234"),"mail" :"yj@chinapnr.com","os" :"win7","company" : "chinapnr"})
登录其中一个sharing：[mgousr03@mongodb-test1etc]$ mongo 172.28.19.237:37017
