1 部署方案图
端口的规划:
mongos为 20000
config server 为 21000
shard1为 22001 , shard2为22002, shard3为22003.
2 前期准备
2.1 服务器的准备
三台服务器f1: 12.112.1.236、f2: 12.112.1.237、f3: 12.112.1.238
(注:此ip为博主随意填写若有巧合请联系修改)
2.2 mogodb文件
使用版本:3.4.4
下载链接:https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.4.4.tgz
将下载的文件拷贝到f1、f2、f3三台服务器的/temp目录下
2.3 相应文件夹的创建
a) 将mongodb-linux-x86_64-rhel62-3.4.4.tgz解压到/app/data/server/mongodb-3.4.4
b) f1、f2、f3建立data 、conf、 config、logs、pid等文件夹
公共文件夹:
mkdir -p /app/data/server/mongodb-3.4.4/conf
mkdir -p /app/data/server/mongodb-3.4.4/data
mkdir -p /app/data/server/mongodb-3.4.4/logs
mkdir -p /app/data/server/mongodb-3.4.4/pid
mkdir -p /app/data/server/mongodb-3.4.4/config
f1创建文件夹:
mkdir -p /app/data/server/mongodb-3.4.4/shard11
mkdir -p /app/data/server/mongodb-3.4.4/shard21
mkdir -p /app/data/server/mongodb-3.4.4/shard31
mkdir -p /app/data/server/mongodb-3.4.4/data/shard11
mkdir -p /app/data/server/mongodb-3.4.4/data/shard21
mkdir -p /app/data/server/mongodb-3.4.4/data/shard31
f2创建文件夹:
mkdir -p /app/data/server/mongodb-3.4.4/shard12
mkdir -p /app/data/server/mongodb-3.4.4/shard22
mkdir -p /app/data/server/mongodb-3.4.4/shard32
mkdir -p /app/data/server/mongodb-3.4.4/data/shard12
mkdir -p /app/data/server/mongodb-3.4.4/data/shard22
mkdir -p /app/data/server/mongodb-3.4.4/data/shard32
f3创建文件夹:
mkdir -p /app/data/server/mongodb-3.4.4/shard13
mkdir -p /app/data/server/mongodb-3.4.4/shard23
mkdir -p /app/data/server/mongodb-3.4.4/shard33
mkdir -p /app/data/server/mongodb-3.4.4/data/shard13

3 启动程序
启动顺序为 mogodb(shard) -> config - > mongos
3.1 shard分片启动
3.1.1.1 创建脚本文件
在f1,f2,f3的目录 /app/data/server/mongodb-3.4.4/bin 下建立 shard-start.sh 执行文件
f1脚本内容如下:
#!/bin/bash
>../logs/shard11.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard11.conf
>../logs/shard21.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard21.conf
>../logs/shard31.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard31.conf
f2脚本内容如下:
#!/bin/bash
>../logs/shard12.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard12.conf
>../logs/shard22.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard22.conf
>../logs/shard32.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard32.conf
f3脚本内容如下:
#!/bin/bash
>../logs/shard13.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard13.conf
>../logs/shard23.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard23.conf
>../logs/shard33.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard33.conf
3.1.1.2 授权
chmod 777 shard-start.sh
3.1.1.3 执行脚本,启动
./shard-start.sh
3.1.1.4 分片初始化
只需在机器f1执行:
分片1初始化:
cd /app/data/server/mongodb-3.4.4/bin
./mongo 12.112.1.236:22001/admin
db.runCommand(
{
"replSetInitiate":
{
"_id":"shard1",
"members":
[
{
"_id":1,
"host":"12.112.1.236:22001",priority:10
},
{
"_id":2,
"host":"12.112.1.237:22001",priority:8
},
{
"_id":3,
"host":"12.112.1.238:22001",arbiterOnly:true
}
]
}
});
分片2初始化:
cd /app/data/server/mongodb-3.4.4/bin
./mongo 12.112.1.236:22002/admin
db.runCommand(
{
"replSetInitiate":
{
"_id":"shard2",
"members":
[
{
"_id":1,
"host":"12.112.1.236:22002",priority:8
},
{
"_id":2,
"host":"12.112.1.237:22002",priority:10
},
{
"_id":3,
"host":"12.112.1.238:22002",arbiterOnly:true
}
]
}
});
分片3初始化:
cd /app/data/server/mongodb-3.4.4/bin
./mongo 12.112.1.236:22003/admin
db.runCommand(
{
"replSetInitiate":
{
"_id":"shard3",
"members":
[
{
"_id":1,
"host":"12.112.1.236:22003"
},
{
"_id":2,
"host":"12.112.1.237:22003"
},
{
"_id":3,
"host":"12.112.1.238:22003",arbiterOnly:true
}
]
}
});
3.1.1.5 移除分片(例如移除分片2)
db.runCommand(
{"removeshard" : "shard2/ 12.112.1.236:22002, 12.112.1.237:22002, 12.112.1.238:22002"}
);
3.2 config启动
3.2.1 创建脚本、授权、启动
在f1,f2,f3目录 /app/data/server/mongodb-3.4.4/bin 建 config-start.sh 执行文件
脚本文件内容如下:
#!/bin/bash
>../logs/config01.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/config.conf && tailf ../logs/config01.log
授权:chmod 777 ./config-start.sh
启动:./config-start.sh
3.2.2 config初始化
./mongo 12.112.1.236:21000/admin
仅需要12.112.1.236这一台执行
db.runCommand(
{
"replSetInitiate":
{
"_id":"cfgReplSet",
"members":
[
{
"_id":1,
"host":"12.112.1.236:21000"
},
{
"_id":2,
"host":"12.112.1.237:21000"
},
{
"_id":3,
"host":"12.112.1.238:21000"
}
]
}
});

}
3.3 mongos启动
3.3.1 创建脚本、授权、启动
在f1,f2,f3目录 /app/data/server/mongodb-3.4.4/bin 建 route-start.sh 执行文件

5.3 程序的启动
服务器f1:
>../logs/shard41.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard41.conf
服务器f2:
>../logs/shard42.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard42.conf
服务器f3:
>../logs/shard43.log && ./mongod -f /app/data/server/mongodb-3.4.4/conf/shard43.conf
shard4初始化
./mongo 127.0.0.1:22004/admin
db.runCommand(
{
"replSetInitiate":
{
"_id":"shard4",
"members":
[
{
"_id":1,
"host":"12.112.1.236:22004",priority:1
},
{
"_id":2,
"host":"12.112.1.237:22004",arbiterOnly:true
},
{
"_id":3,
"host":"12.112.1.238:22004",priority:8
}
]
}
});
5.4 查看分片状态
db.runCommand(
{ addshard : "shard4/12.112.1.236:22004, 12.112.1.237:22004, 12.112.1.238:22004"}
);
db.runCommand( { listshards : 1 } );
5.5 shard4生效
目前搭建了mongodb配置服务器、路由服务器,各个分片服务器,不过应用程序连接到 mongos 路由服务器并不能使用分片机制,还需要在程序里设置分片配置,让分片生效。
./mongo 127.0.0.1:20000/admin
串联路由服务器与分配副本集4
db.runCommand(
{ addshard : "shard4/12.112.1.236:22004, 12.112.1.237:22004, 12.112.1.238:22004"}
);
#查看分片服务器的配置
db.runCommand( { listshards : 1 } );
5.6 移除shard4
移除分片shard4 : db.runCommand( { removeShard: "shard4" } )
