一：使用命令行方式配置mongodb主从

1. [root@server11 ~]#  /usr/local/mongodb/bin/mongod --bind_ip 192.168.1.112 -port 3306 --dbpath /data/mongodb/db1/ --logpath /usr/local/mongodb/logs/server1.log  --rest --master &
2. [1] 14449
3. [root@server12 ~]#  /usr/local/mongodb/bin/mongod --bind_ip 192.168.1.113 --port 3306 --dbpath /data/mongodb/db2/ --logpath /usr/local/mongodb/logs/server2.log  --rest --slave --source 192.168.1.112:3306 &
4. [1] 16853

1. [root@server11 ~]# /usr/local/mongodb/bin/mongo 192.168.1.112:3306
2. MongoDB shell version: 2.2.2
3. connecting to: 192.168.1.112:3306/test
4. > use test
5. switched to db test
6. > db.test.save({b:2})
7. > db.test.find()
8. { "_id" : ObjectId("50fcb7f05712bfb21c866dc6"), "a" : 1 }
9. { "_id" : ObjectId("50fcdccf252ef3433457646f"), "b" : 2 }
10. [root@server12 ~]# /usr/local/mongodb/bin/mongo 192.168.1.113:3306
11. MongoDB shell version: 2.2.2
12. connecting to: 192.168.1.113:3306/test
13. > use test
14. switched to db test
15. > db.test.find()
16. { "_id" : ObjectId("50fcb7f05712bfb21c866dc6"), "a" : 1 }
17. { "_id" : ObjectId("50fcdccf252ef3433457646f"), "b" : 2 }

1. [root@server11 ~]#  /usr/local/mongodb/bin/mongo 192.168.1.112:3306
2. > use local
3. switched to db local
4. > db.addUser('repl','replication')
5. {
6. "user" : "repl",
7. "readOnly" : false,
8. "pwd" : "418b80a28664aeaeb1ec8bf792ea3052",
9. "_id" : ObjectId("50fce98cc4553449b56c6e9f")
10. }
11. [root@server12 ~]#  /usr/local/mongodb/bin/mongo 192.168.1.113:3306
12. > use local
13. switched to db local
14. > db.addUser('repl','replication')
15. {
16. "user" : "repl",
17. "readOnly" : false,
18. "pwd" : "418b80a28664aeaeb1ec8bf792ea3052",
19. "_id" : ObjectId("50fce98cc4553449b56c6e9f")
20. }

四：创建普通用户yang，master端创建即可

1. > use admin
2. switched to db admin
3. > db.addUser('yang','123')
4. > show users
5. {
6. "_id" : ObjectId("50fce0bd15861bedf081584a"),
7. "user" : "yang",
8. "readOnly" : false,
9. "pwd" : "c26040a2869fb7579c83e85c54faaffa"
10. }
11. > db.system.users.find()
12. { "_id" : ObjectId("50fce0bd15861bedf081584a"), "user" : "yang", "readOnly" : false, "pwd" : "c26040a2869fb7579c83e85c54faaffa" }

五：重启mongodb主从实例，以auth方式启动，用户登录测试

1. [root@server11 ~]# /usr/local/mongodb/bin/mongod --bind_ip 192.168.1.112 --auth --port 3306 --dbpath /data/mongodb/db1/ --logpath /usr/local/mongodb/logs/server1.log
2. --rest --master &
3. [root@server12 ~]# /usr/local/mongodb/bin/mongod --bind_ip 192.168.1.113 --auth --port 3306 --dbpath /data/mongodb/db2/ --logpath /usr/local/mongodb/logs/server2.log
4. --rest --slave --source 192.168.1.112:3306 &
5. [root@server11 ~]# /usr/local/mongodb/bin/mongo 192.168.1.112:3306
6. MongoDB shell version: 2.2.2
7. connecting to: 192.168.1.112:3306/test
8. > use admin
9. switched to db admin
10. > show users
11. Mon Jan 21 14:42:47 uncaught exception: error: {
12. "$err" : "unauthorized db:test ns:test.system.users lock type:1 client:192.168.1.112",
13. "code" : 10057
14. }
15. > db.auth('yang','123')
16. 1
17. > show users
18. {
19. "_id" : ObjectId("50fce0bd15861bedf081584a"),
20. "user" : "yang",
21. "readOnly" : false,
22. "pwd" : "c26040a2869fb7579c83e85c54faaffa"
23. }

再次登录web界面需要输入用户名和密码!

五：使用配置文件管理mongodb

1. [root@server11 ~]# cat /etc/mongodb.conf
2. fork = true
3. quiet = true
4. bind_ip = 192.168.1.112
5. port = 3306
6. dbpath = /data/mongodb/db1
7. logpath = /usr/local/mongodb/logs/server1.log
8. logappend = true
9. journal = true
10. rest = true
11. master= true
12. auth = true
13. [root@server11 ~]# /usr/local/mongodb/bin/mongod -f /etc/mongodb.conf
14. all output going to: /usr/local/mongodb/logs/server1.log
15. forked process: 5831
16. child process started successfully, parent exiting
17. [root@server11 ~]# netstat -ntpl |grep mongo
18. tcp        0      0 192.168.1.112:3306          0.0.0.0:*                   LISTEN      5831/mongod
19. tcp        0      0 192.168.1.112:4306          0.0.0.0:*                   LISTEN      5831/mongod
20. [root@server12 ~]# cat /etc/mongodb.conf
21. fork = true
22. quiet = true
23. bind_ip = 192.168.1.113
24. port = 3306
25. dbpath = /data/mongodb/db2
26. logpath = /usr/local/mongodb/logs/server2.log
27. logappend = true
28. journal = true
29. rest = true
30. slave = true
31. source = 192.168.1.112:3306
32. auth = true
33. [root@server12 ~]# /usr/local/mongodb/bin/mongod -f /etc/mongodb.conf
34. all output going to: /usr/local/mongodb/logs/server2.log
35. forked process: 3064
36. child process started successfully, parent exiting
37. [root@server11 ~]# /usr/local/mongodb/bin/mongod -f /etc/mongodb.conf  --shutdown
38. [root@server12 ~]# /usr/local/mongodb/bin/mongod -f /etc/mongodb.conf  --shutdown
