MongoDB (AutoSharding + Replication sets stability test)

Single Replication sets design:

, 10.9.3.228, only Mongos and config services are started.

1. Pai_^ [root @:/usr/local/mongodb/bin] # cat runServerConfig. sh
2. ./Mongod -- configsvr -- dbpath = ../data/config -- logpath = ../data/config. log -- fork
3. Pai_^ [root @:/usr/local/mongodb/bin] # cat runServerMongos. sh
4. ./Mongos -- configdb 10.7.3.228: 27019 -- logpath = ../data/mongos. log -- logappend -- fork

Note: The ip addresses and ports in Mongos are the ip addresses and ports of the config service.

Advanced Configuration AutoSharding

163 of shardv has been started, as long as the autoSharding service of the 165 server is started

1. [Root @ localhost bin] # cat runServerShard. sh
2. ./Mongod -- shardsvr-dbpath = ../data/mongodb -- logpath = ../data/shardsvr_logs.txt -- fork

Configure 163 and 164 Replication

1. [Root @ localhost bin] #./mongo 10.10.21.163: 27018
2. MongoDB shell version: 1.8.2
3. Connecting to: 10.10.21.163: 27018/test
4. > Cfg = {_ id:"Set163164", Members :[
5. ... {_ Id: 0, host:"10.10.21.163: 27018"},
6. ... {_ Id: 1, host:"10.10.21.164: 27017"}
7. ...]}
8. {

15. {

18. }
19. ]
20. }

56. },
57. {
58. "_ Id": 1,
59. "Host":"10.10.21.164: 27017"
60. }
61. ]}
62. Set163164: PRIMARY> rs. isMaster ()
63. {
64. "SetName":"Set163164",
65. "Ismaster":True,
66. "Secondary":False,
67. "Hosts":[
68. "10.10.21.163: 27018",
69. "10.10.21.164: 27017"
70. ],
71. "MaxBsonObjectSize"16777216,
72. "OK": 1
73. }

So far, Replication sets are configured successfully!

Configure the Sharding on the 228 server.

Use admin

1. > Db. runCommand ({addshard:"Set163164/10.10.21.163: 27018, 10.10.21.165: 27018"});
2. {"ShardAdded":"Set163164","OK": 1}
3. > Db. runCommand ({enableSharding:"Test"})
4. {"OK": 1}

 

1. > Db. runCommand ({shardcollection:"Test. users", Key: {_ id: 1 }})
2. {"Collectionsharded":"Test. users","OK": 1}

Then, start the rep service on the 163 and 164 servers respectively, and the 163 server should start the shard service separately.

163:

1. [Root @ localhost bin] # cat runServerShard. sh
2. ./Mongod -- shardsvr -- dbpath = ../data/mongodb -- logpath = ../data/shardsvr_logs.txt -- fork -- replSet set163164

164:

1. [Root @ localhost bin] # cat runServerShard. sh
2. ./Mongod -- dbpath = ../data -- logpath = ../data/shardsvr_logs.txt -- fork -- replSet set162134

So far, AutoSharding + Rep is successfully configured. Then perform the stability test.

First look at the result:

We can see that a total of 163 pieces of data are inserted, and 164 and 165 of the same size are part data.
