MongoDB分片实战
准备目录
/home/mongodb/shard/s0 /home/mongodb/shard/s1 /home/mongodb/config0 /home/mongodb/config1 /home/mongodb/log
启动shard
/usr/local/mongodb/bin/mongod --port 3000 --dbpath=/home/mongodb/shard/s0 --logpath=/home/mongodb/log/s0.log --logappend --fork --shardsvr /usr/local/mongodb/bin/mongod --port 3001 --dbpath=/home/mongodb/shard/s1 --logpath=/home/mongodb/log/s1.log --logappend --fork --shardsvr
启动config
/usr/local/mongodb/bin/mongod --port 3999 --dbpath=/home/mongodb/config/c0 --logpath=/home/mongodb/log/config0.log --logappend --fork --configsvr --replSet=config /usr/local/mongodb/bin/mongod --port 39990 --dbpath=/home/mongodb/config/c1 --logpath=/home/mongodb/log/config1.log --logappend --fork --configsvr --replSet=config
复制集conf配置
/usr/local/mongodb/bin/mongo localhost:3999
rs.initiate({_id: \'config\', members: [{_id: 0, host: \'localhost:3999\'}, {_id: 1, host: \'localhost:39990\'}]})
rs.isMaster() #查看主从关系
创建Route
/usr/local/mongodb/bin/mongos --port 40000 --bind_ip 0.0.0.0 --configdb config/localhost:3999,localhost:39990 --logpath=/home/mongodb/log/route.log --fork --logappend
设置分片
/usr/local/mongodb/bin/mongo admin --port 40000
use admin
db.runCommand({ addshard: \'localhost:3000\'})
db.runCommand({ addshard: \'localhost:3001\'})
db.runCommand({ enablesharding: \'ship_position\'})
db.runCommand({ shardcollection: \'ship_position.ais\', key: {receiveTimeLong: 1}})
db.runCommand({ shardcollection: \'ship_position.gps\', key: {receiveTimeLong: 1}})
db.runCommand({ shardcollection: \'ship_position.rfid\', key: {receiveTimeLong: 1}})
创建用户
use admin
db.createUser(
{
user: "root",
pwd: "QWERpoiu1234",
roles:
[
{ role: "readWrite", db: "config" },
"clusterAdmin"
]
}
)
打开端口
firewall-cmd --zone=public --add-port=40000/tcp --permanent
第二次启动服务
/usr/local/mongodb/bin/mongod --port 3000 --dbpath=/home/mongodb/shard/s0 --logpath=/home/mongodb/log/s0.log --logappend --fork --shardsvr /usr/local/mongodb/bin/mongod --port 3001 --dbpath=/home/mongodb/shard/s1 --logpath=/home/mongodb/log/s1.log --logappend --fork --shardsvr /usr/local/mongodb/bin/mongod --port 3999 --dbpath=/home/mongodb/config/c0 --logpath=/home/mongodb/log/config0.log --logappend --fork --configsvr --replSet=config /usr/local/mongodb/bin/mongod --port 39990 --dbpath=/home/mongodb/config/c1 --logpath=/home/mongodb/log/config1.log --logappend --fork --configsvr --replSet=config /usr/local/mongodb/bin/mongos --port 40000 --bind_ip 0.0.0.0 --configdb config/localhost:3999,localhost:39990 --logpath=/home/mongodb/log/route.log --fork --logappend
