2.修改系统参数(3台)
cat >> /etc/sysctl.conf<<EOF
vm.overcommit_memory=1net.core.somaxconn=1024fs.file-max=655350
EOF
echo never >> /sys/kernel/mm/transparent_hugepage/enabled
echo never>>/sys/kernel/mm/transparent_hugepage/defrag
cat >>/etc/security/limits.conf<<EOF
* soft nproc 655350* hard nproc 655350* soft nofile 655350* hard nofile 655350
EOF
sysctl -p
cat /etc/sysctl.conf
cat /etc/security/limits.conf
3.安装安装包，创建文件夹(3台)
cd /usr/local/
tar zxvf /root/mongodb-linux-x86_64-rhel62-3.5.10.tgz.gz
ln -s mongodb-linux-x86_64-rhel62-3.5.10 mongo
vi /etc/profile
export PATH=/usr/local/mongo/bin/
source /etc/profile
mkdir -p /etc/mongodb
mkdir -p /data/mongodb/configserver/
mkdir -p /data/mongodb/mongos/
mkdir -p /data/mongodb/shard1/

mkdir -p /data/mongodb/shard3/
4.搭建config server(3台)
vi /etc/mongodb/config.conf
directoryperdb=truepidfilepath = /data/mongodb/configserver/mongod.piddbpath= /data/mongodb/configserver/logpath= /data/mongodb/configserver/mongod.loglogappend = truebind_ip= 0.0.0.0port = 28000fork = trueslowms = 500oplogSize=50quiet=trueconfigsvr = truereplSet = configsmaxConns = 20000
mongod -f /etc/mongodb/config.conf
192.168.0.1上：
mongo --port 28000

config = {_id : "configs",members : [{_id : 0, host : "192.168.0.1:28000" },{_id : 1, host : "192.168.0.2:28000" },{_id : 2, host : "192.168.0.3:28000" }]}rs.initiate(config)
5.搭建shard master(3台)
vi /etc/mongodb/shard1.conf
directoryperdb=truepidfilepath = /data/mongodb/shard1/mongod.piddbpath= /data/mongodb/shard1/logpath=/data/mongodb/shard1/mongod.loglogappend = truebind_ip= 0.0.0.0port = 27018 #第一台27018，第二台27019，第三台27020fork = trueslowms = 500oplogSize=50quiet=trueshardsvr = truereplSet = shard1maxConns = 20000
mongod -f /etc/mongodb/shard1.conf
vi /etc/mongodb/shard2.conf
directoryperdb=truepidfilepath = /data/mongodb/shard2/mongod.piddbpath= /data/mongodb/shard2/logpath=/data/mongodb/shard2/mongod.logkeyFile = /data/mongodb/shard2/mongodb.keylogappend = truebind_ip= 0.0.0.0port = 27019 #第一台27019，第二台27020，第三台27018fork = trueslowms = 500oplogSize=50quiet=trueshardsvr = truereplSet = shard2maxConns = 20000
mongod -f /etc/mongodb/shard2.conf
192.168.0.3上：
vi /etc/mongodb/shard3.conf
directoryperdb=truepidfilepath = /data/mongodb/shard3/mongod.piddbpath= /data/mongodb/shard3/logpath=/data/mongodb/shard3/mongod.logkeyFile = /data/mongodb/shard3/mongodb.keylogappend = truebind_ip= 0.0.0.0port = 27020 #第一台27020，第二台27018，第三台27019fork = trueslowms = 500oplogSize=50quiet=trueshardsvr = truereplSet = shard3maxConns = 20000
mongod -f /etc/mongodb/shard3.conf
192.168.0.1上：
mongo --port 27018
初始化副本集
config = {_id : "shard1",members : [{_id : 0, host : "192.168.0.1:27018" },{_id : 1, host : "192.168.0.2:27019" },{_id : 2, host : "192.168.0.3:27020" }]}rs.initiate(config)
192.168.0.2上：
mongo --port 27020
初始化副本集
config = {_id : "shard2",members : [{_id : 0, host : "192.168.0.2:27020" },{_id : 1, host : "192.168.0.1:27019" },{_id : 2, host : "192.168.0.3:27018" }]}rs.initiate(config)
192.168.0.3上：
mongo --port 27019
初始化副本集
config = {_id : "shard3",members : [{_id : 0, host : "192.168.0.3:27019" },{_id : 1, host : "192.168.0.2:27018" },{_id : 2, host : "192.168.0.1:27020" }]}rs.initiate(config)
5.搭建route(3台)
vi /etc/mongodb/mongos.conf
pidfilepath = /data/mongodb/mongos/mongod.pidlogpath=/data/mongodb/mongos/mongod.loglogappend = truebind_ip= 0.0.0.0port = 27017fork = truequiet=truemaxConns = 20000configdb = configs/192.168.0.1:28000,192.168.0.2:28000,192.168.0.3:28000
mongos -f /etc/mongodb/mongos.conf
在任意一台例如192.168.0.1上
mongo --port 27017
use admin
sh.addShard(“shard1/192.168.0.1:27018,192.168.0.2:27019,192.168.0.3:27020”);
sh.addShard(“shard2/192.168.0.2:27020,192.168.0.1:27019,192.168.0.3:27018”);
sh.addShard(“shard3/192.168.0.3:27019,192.168.0.1:27020,192.168.0.2:27018”);
sh.status()
6.测试
sh.enableSharding(“cctest”)
sh.shardCollection(“cctest.user”,{name:1})
use cctest
for(var i=1;i<=100000;i++){db.user.save({_id:i,name:“user-”+i,age:18})}
发现数据库分片到了不同的shard里，搭建成功
