开启授权认证之后,只有经过授权的用户才能够连接到MongoDB,才允许访问相关的资源,增加数据库的安全性与稳定性。
分片集群适合keyFile的形式开启认证,而副本集适合开启auth即可。
思路:为5个集群分片,shard1、shard2、shard3、shard4、shard5分别创建超级用户(用来分别管理Mongo集群的分片),再为集群创建一个管理用户,控制外部链接对集群进程Mongos的访问。
1、为shard1创建分片管理超级用户【shard2,shard3,shard4,shard5类似】
cd/usr/local/mongodb/bin
./mongo 127.0.0.145:22001
#查看副本集状态
shard1:PRIMARY>rs.status()
shard1:PRIMARY>use admin
#添加超级用户
shard1:PRIMARY>db.createUser(
{
user:"ybl_shard1",
pwd:"ybl_shard1",
roles:[{role:"root",db:"admin"}]
}
)
shard1:PRIMARY> db.auth("ybl_shard1","ybl_shard1")
#这一步是为了验证角色是否创建成功,1-成功,其他-失败
#查看用户
shard1:PRIMARY>show users
2、为基于副本集的分片集群创建超级管理用户
cd/usr/local/mongodb/bin
./mongo 127.0.0.143:20000
mongos> use admin
switched to db admin
mongos>db.createUser(
{
user:"yuanbl",
pwd:"yuanbl",
roles:[{role:"root",db:"admin"}]
}
);
db.auth("yuanbl","yuanbl")
mongos> db.auth("yuanbl","yuanbl")
3、关闭集群进程
可先关闭shard服务,systemctl stop mongodb
4、创建keyFile文件
1、mkdir -p /opt/mongo/keyfile/
2、cd/opt/mongo/keyfile
3、openssl rand -base64 753>mongo-keyfile
4、chmod 600 keyfile
注意点:
3步骤中的数字不宜太大,否则启动时会报错
【security
key in /opt/mongo/keyfile/keyfile has length 1368, must be between 6 and 1024
chars】
4步骤一定得执行,要不然报错
【permissions on /opt/mongo/keyfile/mongo-keyfile are too open】
5、将文件keyFile存储在在所有的节点指定位置
mkdir –p /usr/local/mongodb/key
mongo-keyfile存放在此目录下
6、使用keyFile参数指定keyfile启动分片shard1、shard2、shard3、shard4、shard5
修改所有shard启动配置文件,增加keyFile =/usr/local/mongodb/key/mongo-keyfile
然后启动Systemctl start mongodb
7、shard1、shard2、shard3、shard1、shard1、服务器端基于keyfile的用户口令认证测试
./mongo admin --port 22001 -uybl_shard1 -p ybl_shard1
或
./mongo 127.0.0.145:22001
use admin
db.auth(“ybl_shard1”,”ybl_shard1”)
其他类似
如果认证不成功就会报错

到此分片开启成功
8、config server按照如上步骤处理
1、先关闭config server:systemctl stop mongodb 或 kill -2 pid
2、将moongo-keyfile放入目录下/usr/local/mongodb/key,设置权限chmod 600 mongo-keyfile
3、修改config server启动配置文件,加入keyFile = /usr/local/mongodb/key/mongo-keyfile,保存
4、启动config server:
systemctl start mongodb
9、mongos按照如上步骤处理
1、先关闭mongos:systemctl stop mongos或kill -2 pid
2、将moongo-keyfile放入目录下/usr/local/mongodb/key/,设置权限chmod600 mongo-keyfile
3、修改mongos启动配置文件,加入keyFile =/usr/local/mongodb/key/mongo-keyfile,保存
4、启动mongos:
systemctlstart mongos
10、测试分片集群基于keyfile的用户口令认证
cd/usr/local/mongodb/bin/
./mongo127.0.0.143:20000
showdbs

1 #说明认证成功

./mongoadmin --port 20000 -u yuanbl -p yuanbl

./mongo 127.0.0.143:20000
Use admin
db.auth("yuanbl","yuanbl")
