Centos升級到7之后，發(fā)現(xiàn)無法使用iptables控制Linuxs的端口，google之后發(fā)現(xiàn)Centos
7使用firewalld代替了原來的iptables。下面記錄如何使用firewalld開放Linux端口：
firewall-cmd --zone=public --add-port=27017/tcp --permanent firewall-cmd
--zone=public --add-port=27018/tcp --permanent firewall-cmd --zone=public
--add-port=20000/tcp --permanent firewall-cmd --zone=public
--add-port=30000/tcp --permanent
重啟防火墻
firewall-cmd --reload
復(fù)制集加分片(192.168.1.222、192.168.1.223、192.168.1.224)
mkdir /usr/local/mongodb/data/log1 mkdir /usr/local/mongodb/data/log2 mkdir
/usr/local/mongodb/data/shard1 mkdir /usr/local/mongodb/data/shard2 mkdir
/usr/local/mongodb/data/config
1、配置shard1復(fù)制集(3臺都運行)
/usr/nacp/mongodb-linux-x86_64-rhel70-3.4.0/bin/mongod --shardsvr --dbpath
/usr/local/mongodb/data/shard1
--logpath=/usr/local/mongodb/data/log1/shard1.log --logappend --port 27017
--replSet shard1 -fork /usr/nacp/mongodb-linux-x86_64-rhel70-3.4.0/bin/mongo
192.168.1.222:27017 use admin #定義副本集配置
db.runCommand({"replSetInitiate":{"_id":"shard1","members":[{"_id":1,"host":"192.168.1.222:27017"},{"_id":2,"host":"192.168.1.223:27017"},{"_id":3,"host":"192.168.1.224:27017"}]}});
rs.status();
2、配置shard2復(fù)制集(3臺都運行)

{_id:2,host:"192.168.1.224:27018"} ] } rs.initiate(config);
3、配置config(3臺都運行)
/usr/nacp/mongodb-linux-x86_64-rhel70-3.4.0/bin/mongod --port 20000
--configsvr --dbpath=/usr/local/mongodb/data/config

4、配置mongodb路由(3臺都運行)
/usr/nacp/mongodb-linux-x86_64-rhel70-3.4.0/bin/mongos --port 30000 --configdb
config/192.168.1.222:20000,192.168.1.223:20000,192.168.1.224:20000
--logpath=/usr/local/mongodb/data/mongos.log --logappend --fork
配置shard
/usr/nacp/mongodb-linux-x86_64-rhel70-3.4.0/bin/mongo 192.168.1.222:30000 use
admin db.runCommand({
addshard:"shard1/192.168.1.222:27017,192.168.1.223:27017,192.168.1.224:27017"
}) db.runCommand({
addshard:"shard2/192.168.1.222:27018,192.168.1.223:27018,192.168.1.224:27018" })
設(shè)置分片數(shù)據(jù)庫：
db.runCommand({"enablesharding": "test"})
設(shè)置表分片基于字段hash設(shè)置表分片基于字段
db.runCommand({"shardcollection": "test.t1", key: { id:1}})
打印數(shù)據(jù)庫分片信息：
db.printShardingStatus()
打印服務(wù)器信息：
db.serverStatus()
測試
use test for (var i = 1; i <= 10000; i++)
db.t1.save({id:i,"test1":"testval1"});
