篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Mongodb4.4.1分片集群搭建相关的知识,希望对你有一定的参考价值。
1、环境规划
3台机,每台机5个实例,分别mongos 1 个,config server 1 个,shard server 3 个
IP:192.168.56.107(mongodb01) 实例:mongos:30000 shard1:40001(主节点) shard2:40002(仲裁节点) shard3:40003(副节点) config:27027
IP:192.168.56.105(mongodb02) 实例:mongos:30000 shard1:40001(副节点) shard2:40002(主节点) shard3:40003(仲裁节点) config:27028
IP:192.168.56.106(mongodb03) 实例:mongos:30000 shard1:40001(仲裁节点) shard2:40002(副节点) shard3:40003(主节点) config:27029
2、创建相应目录
在192.168.56.107(mongodb01)上新建:
mkdir -p /mongodb01/{data,logs,apps,run}
mkdir -p /mongodb01/data/shard{1,2,3}
mkdir -p /mongodb01/data/config
在192.168.56.105(mongodb02)上新建:
mkdir -p /mongodb02/{data,logs,apps,run}
mkdir -p /mongodb02/data/shard{1,2,3}
mkdir -p /mongodb02/data/config
在192.168.56.106(mongodb03)上新建:
mkdir -p /mongodb03/{data,logs,apps,run}
mkdir -p /mongodb03/data/shard{1,2,3}
mkdir -p /mongodb03/data/config
3、配置环境变量
使用root账号修改配置,/mongodb01/apps/bin 用于存放mongodb的执行程序
echo ‘export PATH=$PATH:/mongodb01/apps/bin‘ >> /etc/profile
source /etc/profile
使用root账号修改配置,/mongodb01/apps/bin 用于存放mongodb的执行程序
echo ‘export PATH=$PATH:/mongodb02/apps/bin‘ >> /etc/profile
source /etc/profile
使用root账号修改配置,/mongodb01/apps/bin 用于存放mongodb的执行程序
echo ‘export PATH=$PATH:/mongodb03/apps/bin‘ >> /etc/profile
source /etc/profile
4、创建用户及修改权限
Mongodb01下:
groupadd -g 10001 mongodb
useradd -u 10001 -g mongodb mongodb
id mongodb
passwd mongodb
输入新的密码:123
chown -R mongodb:mongodb /mongodb01
chmod -R 775 /mongodb01
Mongodb02下:
groupadd -g 10001 mongodb
useradd -u 10001 -g mongodb mongodb
id mongodb
passwd mongodb
输入新的密码:123
chown -R mongodb:mongodb /mongodb02
chmod -R 775 /mongodb02
Mongodb03下:
groupadd -g 10001 mongodb
useradd -u 10001 -g mongodb mongodb
id mongodb
passwd mongodb
输入新的密码:123
chown -R mongodb:mongodb /mongodb03
chmod -R 775 /mongodb03
5、下载安装文件
切换用户:
su mongodb
Mongodb01下:切换目录:
cd /mongodb01/apps
下载文件
wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.4.1.tgz
解压文件
tar -xf mongodb-linux-x86_64-rhel70-4.4.1.tgz
mv mongodb-linux-x86_64-rhel70-4.4.1/bin ./
rm -rf mongodb-linux-x86_64-rhel70-4.4.1
Mongodb02下:切换目录:
cd /mongodb02/apps
下载文件
wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.4.1.tgz
解压文件
tar -xf mongodb-linux-x86_64-rhel70-4.4.1.tgz
mv mongodb-linux-x86_64-rhel70-4.4.1/bin ./
rm -rf mongodb-linux-x86_64-rhel70-4.4.1
Mongodb03下:切换目录:
cd /mongodb03/apps
下载文件
wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.4.1.tgz
解压文件
tar -xf mongodb-linux-x86_64-rhel70-4.4.1.tgz
mv mongodb-linux-x86_64-rhel70-4.4.1/bin ./
rm -rf mongodb-linux-x86_64-rhel70-4.4.1
6、创建配置文件
Mongodb01下新建文件目录:
mkdir -p /mongodb01/apps/conf/
vi /mongodb01/apps/conf/mongodb01-config.yml
echo "systemLog:
destination: file
# 注意修改路径
path: "/mongodb01/logs/mongodb01-config.log"

7、部署配置服务器集群(三台机器都要操作)
启动config服务(3台机器执行相同操作,只是在不同的mongodb上启动时需要修改mongodb0,此处只演示mongodb01上的配置部署)
在mongodb01下
cd /mongodb01/apps/conf/
mongod --config /mongodb01/apps/conf/mongodb01-config.yml
连接一个实例
mongo 192.168.56.107:27027(此处三台机器一致)
初始化复制集
(这个 mgconfig 名字一定要和config 配置文件中 replSet 的名字一致)
```config={id:"mgconfig",members:[{id:0,host:"192.168.56.107:27027"},{id:1,host:"192.168.56.105:27028"},{id:2,host:"192.168.56.106:27029"},]}
rs.initiate(config)
检查状态
rs.status()
复制集配完后,可能状态不会马上改变(可能都是secondary),过几秒就会自动更新 ![](https://s4.51cto.com/images/blog/202012/03/802a176d4595cb00dd85150780c9aa05.png?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)
8、部署shard1分片集群(3台机器都要操作,此处只操作mongodb01)
启动3台shard1实例
cd /mongodb01/apps/conf/
mongod --config /mongodb01/apps/conf/mongodb01-shard1.yml
连接一个实例
mongo 192.168.56.107:40001(3台机器一致)
创建复制集
use admin
config={_id:"shard1",members:[{_id:0,host:"192.168.56.107:40001",priority:2},{_id:1,host:"192.168.56.105:40001",priority:1},{_id:2,host:"192.168.56.106:40001",arbiterOnly:true},]}
这个 shard1名字一定要和 shard1配置文件中 replSet 的名字一致
初始化复制集
rs.initiate(config)
检查状态
rs.status()
复制集配完后,可能状态不会马上改变(可能都是secondary),过几秒就会自动更新
9、部署shard2分片集群(3台机器都要操作,此处只示范mongodb01)
启动3台shard2实例
cd /mongodb01/apps/conf/
mongod --config /mongodb01/apps/conf/mongodb01-shard2.yml
连接第二个节点创建复制集
为什么是连接第二个,因为规划的shard2 的主节点是105:40002,仲裁节点不能写数据,所以这里不能连107,要连105
mongo 192.168.56.105:40002(三台机器一致)
创建复制集
use admin
config={_id:"shard2",members:[{_id:0,host:"192.168.56.107:40002",arbiterOnly:true},{_id:1,host:"192.168.56.105:40002",priority:2}, {_id:2,host:"192.168.56.106:40002",priority:1},]}
这个 shard2名字一定要和 shard2配置文件中 replSet 的名字一致
初始化复制集
rs.initiate(config)
检查状态
rs.status()
复制集配完后,可能状态不会马上改变(可能都是secondary),过几秒就会自动更新
10、部署shard3分片集群(3台机器都要操作,这里只示范mongodb01)
启动3台shard3实例
cd /mongodb01/apps/conf/
mongod --config /mongodb01/apps/conf/mongodb01-shard3.yml
连接第三个节点创建复制集
为什么是连接第三个,因为规划的shard3 的主节点是106:40003
mongo 192.168.56.106:40003(3台机器一致)
创建复制集
use admin
config={_id:"shard3",members:[{_id:0,host:"192.168.56.107:40003",priority:1},{_id:1,host:"192.168.56.105:40003",arbiterOnly:true},
{_id:2,host:"192.168.56.106:40003",priority:2},]}
这个 shard3名字一定要和 shard3配置文件中 replSet 的名字一致
初始化复制集
rs.initiate(config)
检查状态
rs.status()
复制集配完后,可能状态不会马上改变(可能都是secondary),过几秒就会自动更新
11、启用分片功能
登陆路由节点
cd /mongodb01/apps/conf/
mongos --config /mongodb01/apps/conf/mongodb01-route.yml
mongo 192.168.56.107:30000
use admin
sh.addShard("shard1/192.168.56.107:40001,192.168.56.105:40001,192.168.56.106:40001")
sh.addShard("shard2/192.168.56.107:40002,192.168.56.105:40002,192.168.56.106:40002")
sh.addShard("shard3/192.168.56.107:40003,192.168.56.105:40003,192.168.56.106:40003")
检查状态
sh.status()
12、服务脚本
编写服务脚本,便于启动和停止集群
#!/bin/bash

13、测试服务器分片功能
模拟写入数据
在tydb库的tyuser表中循环写入6万条数据
mongo 192.168.56.107:30000
use tydb
show collections
for(i=1;i<=60000;i++){db.tyuser.insert({"id":i,"name":"ty"+i})}
启用数据库分片
sh.enableSharding("tydb")
创建的索引
db.tyuser.createIndex({"id":1})
启用表分片
sh.shardCollection(”tydb.tyuser",{"id":1})
查看分片情况
sh.status()
开启平衡器
use admin
sh.startBalance()
关闭平衡器
use admin
sh.stopBalancer()
查看是否关闭
返回flase表示平衡器已关闭,还需要查询均衡器正在运行的 情况
sh.getBalancerState()
