部署集群

部署 Config Server 集群

分别在三台上启动 Config Server 容器

# mongodb1
docker run -d --name configsvr1 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v configsvr1_data:/data/configdb \-p 27019:27019 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --configsvr --replSet configReplSet --bind_ip_all

# mongodb2
docker run -d --name configsvr2 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v configsvr2_data:/data/configdb \-p 27019:27019 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --configsvr --replSet configReplSet --bind_ip_all

# mongodb3
docker run -d --name configsvr3 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v configsvr3_data:/data/configdb \-p 27019:27019 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --configsvr --replSet configReplSet --bind_ip_all

初始化 Config Server 复制集

1. 登录 configsvr1 容器

docker exec -it configsvr1 mongo --port 27019

2. 执行初始化脚本

rs.initiate({_id: "configReplSet",configsvr: true,members: [{ _id: 0, host: "192.168.31.135:27019" },{ _id: 1, host: "192.168.31.109:27019" },{ _id: 2, host: "192.168.31.165:27019" }]
})

3. 验证状态

rs.status()

部署 Shard Server 集群

在 mongo1 上部署容器

docker run -d --name shard1_node1 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard1_node1_data:/data/db \-p 27018:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard1ReplSet --bind_ip_alldocker run -d --name shard2_node1 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard2_node1_data:/data/db \-p 27017:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard2ReplSet --bind_ip_alldocker run -d --name shard3_node1 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard3_node1_data:/data/db \-p 27016:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard3ReplSet --bind_ip_all

在 mongo2 上部署容器

docker run -d --name shard1_node2 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard1_node2_data:/data/db \-p 27018:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard1ReplSet --bind_ip_alldocker run -d --name shard2_node2 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard2_node2_data:/data/db \-p 27017:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard2ReplSet --bind_ip_alldocker run -d --name shard3_node2 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard3_node2_data:/data/db \-p 27016:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard3ReplSet --bind_ip_all

在 mongo3 上部署容器

docker run -d --name shard1_node3 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard1_node3_data:/data/db \-p 27018:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard1ReplSet --bind_ip_alldocker run -d --name shard2_node3 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard2_node3_data:/data/db \-p 27017:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard2ReplSet --bind_ip_alldocker run -d --name shard3_node3 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \-v shard3_node3_data:/data/db \-p 27016:27018 \mongodb/mongodb-community-server:5.0.27-ubuntu2004 \mongod --shardsvr --replSet shard3ReplSet --bind_ip_all

将 shard1 shard2 shard3 容器初始化并验证

docker exec -it shard1_node1 mongo --port 27018

rs.initiate({_id: "shard1ReplSet",members: [{ _id: 0, host: "192.168.31.135:27018" },{ _id: 1, host: "192.168.31.109:27018" },{ _id: 2, host: "192.168.31.165:27018" }]
})rs.status()

docker exec -it shard2_node1 mongo --port 27018

rs.initiate({_id: "shard2ReplSet",members: [{ _id: 0, host: "192.168.31.135:27017" },{ _id: 1, host: "192.168.31.109:27017" },{ _id: 2, host: "192.168.31.165:27017" }]
})rs.status()

docker exec -it shard3_node1 mongo --port 27018

rs.initiate({_id: "shard3ReplSet",members: [{ _id: 0, host: "192.168.31.135:27016" },{ _id: 1, host: "192.168.31.109:27016" },{ _id: 2, host: "192.168.31.165:27016" }]
})rs.status()

部署 Mongos 路由器

docker run -d --name mongos -p 27015:27017 \--log-opt max-size=100m --log-opt max-file=3 --restart=unless-stopped \mongodb/mongodb-community-server:5.0.27-ubuntu2004 mongos --bind_ip_all --configdb configReplSet/192.168.31.135:27019,192.168.31.109:27019,192.168.31.165:27019

关联 Shard 集群至 Config 集群

docker exec -it mongos mongo

sh.addShard("shard1ReplSet/192.168.31.135:27018,192.168.31.109:27018,192.168.31.165:27018")
sh.addShard("shard2ReplSet/192.168.31.135:27017,192.168.31.109:27017,192.168.31.165:27017")
sh.addShard("shard3ReplSet/192.168.31.135:27016,192.168.31.109:27016,192.168.31.165:27016")

数据库手动指定分片

使能分片数据库

sh.enableSharding("metadata")

指定分片集合

# sh.shardCollection("mydatabase.mycollection", { myfield: 1 })
sh.shardCollection("metadata.file-10-million", { key: 1 })

查看分片分布

# db.collection.getShardDistribution()
db['file-10-million'].getShardDistribution()
