2. Install the package
Current servers:
server1(192.168.1.67):
shard1: /home/mongo/data/shard11
shard2: /home/mongo/data/shard21
config1: /home/mongo/data/config
mongos
server2(192.168.1.68):
shard1: /home/mongo/data/shard12
shard2: /home/mongo/data/shard22
config2: /home/mongo/data/config
mongos
Note: server1 & server2 set up to Replica Sets.
1) server1 tree:

3. Configuring the Replica Sets
1) Start shard1 replica set
# /home/mongo/bin/mongo -port 10000 -host 192.168.1.67
> config = {_id:'shard1',members:[{_id: 0, host: '192.168.1.67:10000'},{_id: 1, host: '192.168.1.68:10000'}]}
> rs.initiate(config);
2) Start shard2 replica set
# /home/mongo/bin/mongo -port 10000 -host 192.168.1.67
> config = {_id:'shard2',members:[{_id: 0, host: '192.168.1.67:10001'},{_id: 1, host: '192.168.1.68:10001'}]}
> rs.initiate(config);
4. Mongo start scripts
1) server1
# cat /home/mongo/bin/mongo.start.sh
/home/mongo/bin/mongod -shardsvr -replSet shard1 -port 10000 -dbpath /home/mongo/data/shard11 -oplogSize 100 -logpath /home/mongo/data/shard11/shard11.log -fork
/home/mongo/bin/mongod -shardsvr -replSet shard2 -port 10001 -dbpath /home/mongo/data/shard21 -oplogSize 100 -logpath /home/mongo/data/shard21/shard21.log -fork
/home/mongo/bin/mongod -configsvr -dbpath /home/mongo/data/config -port 20000 -logpath /home/mongo/data/config/config.log -logappend -fork
/home/mongo/bin/mongos -configdb 192.168.1.67:20000 -port 30000 -chunkSize 5 -logpath /home/mongo/data/mongos.log -logappend -fork
2) server2
# cat /home/mongo/bin/mongo.start.sh
/home/mongo/bin/mongod -shardsvr -replSet shard1 -port 10000 -dbpath /home/mongo/data/shard12 -oplogSize 100 -logpath /home/mongo/data/shard12/shard12.log -fork
/home/mongo/bin/mongod -shardsvr -replSet shard2 -port 10001 -dbpath /home/mongo/data/shard22 -oplogSize 100 -logpath /home/mongo/data/shard22/shard22.log -fork
/home/mongo/bin/mongod -configsvr -dbpath /home/mongo/data/config -port 20000 -logpath /home/mongo/data/config/config.log -logappend -fork
/home/mongo/bin/mongos -configdb 192.168.1.67:20000 -port 30000 -chunkSize 5 -logpath /home/mongo/data/mongos.log -logappend -fork
Note: mongos only use 1 or 3 configdb.
5. Configuring the Shard Cluster
# /home/mongo/bin/mongo 192.168.1.67:30000/admin
> db
admin
> db.runCommand({addshard:"shard1/192.168.1.67:10000,192.168.1.68:10000", name:"s1", maxsize:20480});
{ "shardAdded" : "s1", "ok" : 1 }
> db.runCommand({addshard:"shard2/192.168.1.67:10001,192.168.1.68:10001", name:"s2", maxsize:20480});
{ "shardAdded" : "s2", "ok" : 1 }
> db.runCommand({listshards:1})
{
"shards" : [
{
"_id" : "s1",
"host" : "shard1/192.168.1.67:10000,192.168.1.68:10000"
},
{
"_id" : "s2",
"host" : "shard2/192.168.1.67:10001,192.168.1.68:10001"
}
],
"ok" : 1
}
> db.runCommand({enablesharding:"test_database"})
{ "ok" : 1 }
