分片搭建参照上篇文档:mongo Shard部署
configserver:
配置
vi ~/configserver/conf/configserver.conf
#log logpath = ./log/configserver.log logappend = true #listen port port = 8222 #db path dbpath = ./data/configserver/ #independent dir per db directoryperdb = true #namespace disk size nssize = 500 #max connection numbers maxConns = 2048 #relication log size oplogSize = 10240 #monitor rest = true
启动
nohup numactl --interleave=all ./bin/mongod -f ./conf/configserver.conf --configsvr --keyFile=./conf/secretKey >/dev/null 2>&1 &
--configsvr //启动mongod作为config server
mongos:
配置
vi ~/mongos/conf/mongos.conf
#log logpath = ./log/mongos.log logappend = true #listen port = 8333 port = 8333 #config server ip:port configdb = host1:8222,host2:8222,host36:8222 #max connection numbers maxConns = 2048 noAutoSplit = true
启动
nohup ./bin/mongos -f ./conf/mongos.conf --keyFile=./conf/secretKey >/dev/null 2>&1 &
加分片
./bin/mongo --host 127.0.0.1 --port 8333
>sh.addShard("shardName/ip:port")
shardName/ip:port //shardName为具体分片名,ip:port为分片中的任意一个ip:port即可
本例中执行
>sh.addShard("shard00/host1:8111")
>sh.addShard("shard01/host1:8112")
查询状态
>sh.status()
添加用户
./bin/mongo --host 127.0.0.1 --port 8333
>use admin
>db.addUser("username","password")
登录
./bin/mongo 127.0.0.1:8333/admin -u username -p password
