mongodb安裝最新版本并恢複成相同的舊環境

需求方說有一個mongo節點挂掉了，現在需要按照原來的配置重新搭建mongodb，并換成mongodb最新版本： 

目前的環境： 

[root@mongodb1 ~]# ps -ef|grep mongo 

avahi     2502     1  0 sep24 ?        00:24:33 avahi-daemon: running [mongodb1.local]

root     24368 24349  0 14:20 pts/1    00:00:00 grep mongo 

同時可以看到資料的存放目錄 

/home/mongodb/data/shard1t   ---29017 

/home/mongodb/data1/shard2t  ---29018

根據要求，我們可以這樣建立： 

/home/mongodb/data1/shard2n  ---29019   ---這個目錄是之前那個挂掉的分片使用的，我們可以繼續沿用

下面可以開始删除原始資料了 

删除資料： 

cd /home/mongodb/data/shard1t    rm -fr * 

cd /home/mongodb/data1/shard2t   rm -fr * 

cd /home/mongodb/data1/shard2n   rm -fr * 

删除日志： 

cd /home/mongodb/data/  rm -f *log* 

删除配置目錄下内容： 

cd /home/mongodb/data/configt/ 

可以重新搭建新環境了： 

啟動configs： 

/home/mongodb/mongodb-linux-x86_64-3.2.0/bin/mongod --configsvr --dbpath /home/mongodb/data/configt/ --port 27000 -logpath /home/mongodb/data/configt.log --fork 

啟動mongos： 

/home/mongodb/mongodb-linux-x86_64-3.2.0/bin/mongos --configdb 192.168.12.220:27000 -port 45000 -chunksize 1024 --logpath /home/mongodb/data/mongost.log -fork   

啟動三個mongod分片： 

/home/mongodb/mongodb-linux-x86_64-3.2.0/bin/mongod -shardsvr -port 29017 -dbpath /home/mongodb/data/shard1t -oplogsize 10000 -logpath /home/mongodb/data/shard1t.log -fork --rest 

/home/mongodb/mongodb-linux-x86_64-3.2.0/bin/mongod -shardsvr -port 29018 -dbpath /home/mongodb/data1/shard2t -oplogsize 10000 -logpath /home/mongodb/data/shard2t.log -fork --rest 

/home/mongodb/mongodb-linux-x86_64-3.2.0/bin/mongod -shardsvr -port 29019 -dbpath /home/mongodb/data1/shard2n -oplogsize 10000 -logpath /home/mongodb/data/shard2n.log -fork --rest 

連接配接到mongos添加三個分片： 

[root@mongodb1 data]# /home/mongodb/mongodb-linux-x86_64-3.2.0/bin/mongo 192.168.12.220:45000/admin

  balancer: 

currently enabled:  yes 

currently running:  no 

failed balancer rounds in last 5 attempts:  0 

migration results for the last 24 hours: 

no recent migrations 

建立庫: 

mongos>use vds     ---直接use dbname就可以建立庫，但必須保證庫裡有表，不然空庫就被自動删除了。 

建立表： 

mongos> db.t_url_count.insert(  

}) 

mongos> db.t_url_event.insert({"_id" : objectid("53c88772ffee1a1f14072e41"), 

"utime" : "2014-07-09 14:31:10"}) 

writeresult({ "ninserted" : 1 }) 

檢視表： 

mongos> show collections; 

建立索引： 

mongos> use vds; 

mongos> db.t_url_event.ensureindex({"source":1, "add_date":1}) 

"raw" : { 

"192.168.12.220:29017" : { 

"createdcollectionautomatically" : false, 

"numindexesbefore" : 1, 

"numindexesafter" : 2, 

"ok" : 1 

}, 

mongos> db.t_url_count.ensureindex({"add_date":1, "sub_url_hash":1}) 

設定允許庫分片： 

mongos> db.runcommand({"enablesharding":"vds"}); 

{ "ok" : 1 } 

添加表到分片: 

mongos> db.runcommand({"shardcollection":"vds.t_url_count","key":{"add_date":1, "sub_url_hash":1}}) 

{ "collectionsharded" : "vds.t_url_count", "ok" : 1 } 

mongos> db.runcommand({"shardcollection":"vds.t_url_event","key":{"source":1, "add_date":1}}) 

{ "collectionsharded" : "vds.t_url_event", "ok" : 1 } 

檢視最後結果： 

mongos> db.printshardingstatus()
