mongodb集群
组件：
mongos：请求分发
config server 配置服务器
shard 分片数据服务器
三台机器
192.168.174.128
192.168.174.129
192.168.174.130
服务器规划
端口分配：
mongos：20000
config：21000
shard1：27001
shard2：27002
shard3：27003
服务器需要同步时间，否则测试不通过
128机器操作
1、下载官网:
2、解压
tar -xf mongodb-linux-x86_64-rhel70-3.6.5.tgz && mv mongodb-linux-x86_64-rhel70-3.6.5 /usr/local/mongodb
3、加环境变量，方便操作(3台机器)
vim /etc/profile
export PATH=$PATH:/usr/local/mongodb/bin
source /etc/profile
4、创建所需目录
mkdir -p /usr/local/mongodb/{conf,config/{data,log},shard1/{data,log},shard2/{data,log},shard3/{data,log},mongos/log}
5、编写配置文件config.conf、shard1.conf、shard2.conf、shard3.conf、mongos.conf

6、将mongodb目录scp到其两台服务器
scp -r /usr/local/mongodb 192.168.174.130:/usr/local/mongodb
scp -r /usr/local/mongodb 192.168.174.131:/usr/local/mongodb
**注意：130和131节点，配置文件中的bindIp需要修改为对应的IP
7、创建用户，授权（三台机器）
useradd mongod
chown -R mongod:mongod /usr/local/mongodb/
============================================================================
8、启动配置服务器（3台）
mongod -f /usr/local/mongodb/conf/config.conf
9、初始化副本集（登陆任意一个实例即可）
#连接
mongo 192.168.174.128:21000
#初始化副本集
rs.initiate(
{
_id: "configs",
configsvr: true,
members: [
{ _id : 0, host : "192.168.174.128:21000" },
{ _id : 1, host : "192.168.174.130:21000" },
{ _id : 2, host : "192.168.174.131:21000" }
]
}
)
#查看状态
rs.status();
==============================================================================
10、启动shard1、shard2、shard3（3台）
mongod -f /usr/local/mongodb/conf/shard1.conf
mongod -f /usr/local/mongodb/conf/shard2.conf
mongod -f /usr/local/mongodb/conf/shard3.conf
11、初始化副本集（在一台执行即可）
#连接
mongo 192.168.174.130:27001
#初始化副本集
rs.initiate(
{
_id : "shard1",
members: [
{ _id : 0, host : "192.168.174.128:27001",priority:2},
{ _id : 1, host : "192.168.174.130:27001",priority:1},
{ _id : 2, host : "192.168.174.131:27001",arbiterOnly: true}
]
}
)
#查看状态
rs.status();
#连接
mongo 192.168.174.131:27002
#初始化副本集
rs.initiate(
{
_id : "shard2",
members: [
{ _id : 0, host : "192.168.174.128:27002",arbiterOnly: true},
{ _id : 1, host : "192.168.174.130:27002",priority:2},
{ _id : 2, host : "192.168.174.131:27002",priority:1}
]
}
)
#查看状态
rs.status();
#连接
mongo 192.168.174.128:27003
#初始化副本集
rs.initiate(
{
_id : "shard3",
members: [
{ _id : 0, host : "192.168.174.128:27003",priority:1},
{ _id : 1, host : "192.168.174.130:27003",arbiterOnly: true},
{ _id : 2, host : "192.168.174.131:27003",priority:2}
]
}
)
#查看状态
rs.status();
===============================================================================
12、启动mongos（3台）
mongos -f /usr/local/mongodb/conf/mongos.conf
13、启用分片（登陆任意一个实例）
mongo 192.168.174.128:20000
use admin
sh.addShard("shard1/192.168.174.128:27001,192.168.174.130:27001,192.168.174.130:27001");
sh.addShard("shard2/192.168.174.128:27002,192.168.174.130:27002,192.168.174.130:27002");
sh.addShard("shard3/192.168.174.128:27003,192.168.174.130:27003,192.168.174.130:27003");
#查看集群状态
sh.status();
===============================================================================
14、测试
设置chunk大小
use config
db.settings.save({ "_id" : "chunksize", "value" : 1 })
#为方便测试设为1M，否则需要插入大量数据才会分片存储
登陆
mongo 192.168.127.128:20000
指定testdb分片生效
use admin;
db.runCommand({ enablesharding :"testdb"});
指定需要分片的集合和片键
db.runCommand({ shardcollection : "testdb.table1",key : {id: 1} });
use testdb;
插入数据
for (var i = 1; i <= 10000; i++) db.table1.save({id:i,"test1":"testval1"});
查看是分片情况
db.table1.stats();
可以看到数据分到3个分片，各自分片数量为： shard1 “count” : 42183，shard2 “count” : 38937，shard3 “count” : 18880。已经成功了！
启动关闭
mongodb的启动顺序是，先启动配置服务器，在启动分片，最后启动mongos.
mongod -f /usr/local/mongodb/conf/config.conf
mongod -f /usr/local/mongodb/conf/shard1.conf
mongod -f /usr/local/mongodb/conf/shard2.conf
mongod -f /usr/local/mongodb/conf/shard3.conf
mongos -f /usr/local/mongodb/conf/mongos.conf
关闭时，直接killall杀掉所有进程（测试使用）
pkill mongo
MongoDB 分片集群
