MongoDB 3.0于2015年3月3日正式发布。可以毫不夸张的说，该版本的新增特性标志着MongoDB这款典型的NoSQL数据库已经进入了一个全新的发展阶段。
由于使用到3.0新增的功能，我们决定升级mongodb-3.0.3
本地测试
IP：192.168.5.66
系统版本:Centos6.5_64-2.6.32
Mongodb版本：
mongodb-linux-x86_64-2.6.7.tgz
mongodb-linux-x86_64-3.0.3.gz

分片配置：
分片1：/usr/local/mongodb-2.6.7/bin/mongo 192.168.5.66:27011
config = {_id:"replset1", members:[
{_id:0,host:"192.168.5.66:27001",priority:4},
{_id:1,host:"192.168.5.66:27011",priority:5},
{_id:2,host:"192.168.5.66:27000",arbiterOnly:true},
]
}
rs.initiate(config); //更新配置
rs.status() //查看配置信息
分片2：/usr/local/mongodb-2.6.7/bin/mongo 192.168.5.66:27022
config = {_id:"replset2", members:[
{_id:0,host:"192.168.5.66:27002",priority:4},
{_id:1,host:"192.168.5.66:27022",priority:5},
{_id:2,host:"192.168.5.66:27222",arbiterOnly:true},
]
}
rs.initiate(config); //更新配置
rs.status() //查看配置信息
mongos添加路由信息：/usr/local/mongodb-2.6.7/bin/mongo 192.168.5.66:27111/admin
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。
#串联路由服务器与分配副本集1
db.runCommand({addshard :"replset1/192.168.5.66:27001,192.168.5.66:27011"});
#串联路由服务器与分配副本集1
db.runCommand({addshard :"replset2/192.168.5.66:27002,192.168.5.66:27022"});
use admin
printShardingStatus() //查看分片信息
use testapm
for (var i= 1; i <= 20; i++)db.haha.save({tid:i,name:"username"+i,age:i});
for (var i= 1; i <= 10; i++)db.table1.save({tid:i,name:"username"+i,age:i});
for (var i= 1; i <= 15; i++)db.table2.save({tid:i,name:"username"+i,age:i});
use crash
for (var i= 1; i <= 15; i++)db.tab1.save({tid:i,name:"username"+i,age:i});
for (var i= 1; i <= 15; i++)db.tab2.save({tid:i,name:"username"+i,age:i});
for (var i= 1; i <= 15; i++)db.table3.save({tid:i,name:"username"+i,age:i});
拷贝配置文件：
cp /usr/local/mongodb-2.6.7/conf/* /usr/local/mongodb-3.0.3/conf/
mongodb3.0.3的数据目录和2.6.7数据目录分开
创建新的数据目录：
mkdir /data/mdb2/{shard1,configdb,shard11,shard2,shard22,arbiter1,arbiter2}/data -p
需要修改3.0.3版本配置文件，修改数据存储路径：
configdb.conf ==》 dbpath = /data/mdb2/configdb/data
shard1.conf ==》 dbpath = /data/mdb2/shard1/data storageEngine=wiredTiger //添加新的数据引擎
shard11.conf ==》 dbpath = /data/mdb2/shard11/data storageEngine=wiredTiger //添加新的数据引擎
shard2.conf ==》 dbpath = /data/mdb2/shard2/data storageEngine=wiredTiger //添加新的数据引擎
shard22.conf ==》 dbpath = /data/mdb2/shard22/data storageEngine=wiredTiger //添加新的数据引擎
arbiter1.conf ==》 dbpath = /data/mdb2/arbiter1/data storageEngine=wiredTiger //添加新的数据引擎
arbiter2.conf ==》 dbpath = /data/mdb2/arbiter2/data storageEngine=wiredTiger //添加新的数据引擎
首先备份configdb数据库：
/usr/local/mongodb-2.6.7/bin/mongodump -h192.168.5.66:27100 -o 2.6.7conf
然后停掉configdb
启动3.0.3 configdb：
/usr/local/mongodb-3.0.3/bin/mongod -f /usr/local/mongodb-3.0.3/conf/configdb.conf
mongos停掉然后执行
/usr/local/mongodb-3.0.3/bin/mongos -f/usr/local/mongodb-3.0.3/conf/mongos.conf --upgrade
启动mongos3.0.3：
/usr/local/mongodb-3.0.3/bin/mongos -f/usr/local/mongodb-3.0.3/conf/mongos.conf
configdb导入数据：/usr/local/mongodb-3.0.3/bin/mongorestore -h192.168.5.66:27100 --dir /root/2.6.7conf/
Configdb和mongos3.0.3升级完成
5.数据库升级3.0.3
a.将2.6.7版的分片1主库停掉，2.6.7版本从库自动升级为主库，启动配置为3.0.3版本新的数据引擎, 启动以后开始复制数据数据复制完以后接管主库。
连接3.0.3版本分片1主库查看：

c.升级2.6.7仲裁节点arbiter1和2.6.7分片2步骤和上边一样不在描述
6.不同版本数据size变化
mongo-2.6.7版本数据：
mongo-3.0.3版本数据：
总结：**注意最终还是需要停mongos和configdb（mongos和configdb也需要升级，停止几分钟即可）**
Mongo-2.6.7数据升级（导入）为Mongo-3.0.3。数据显示要比老版本少，不确定是不是新的引擎数据有压缩。
注意：该环境为测试环境测试，仅供参考。
线上环境升级请在测试环境模拟线上测试，在确认没有问题，再在线上实施。
