mongodb安装最新版本并恢复成相同的旧环境

需求方说有一个mongo节点挂掉了，现在需要按照原来的配置重新搭建mongodb，并换成mongodb最新版本：

当前的环境：
[root@mongodb1 ~]# ps -ef|grep mongo
avahi     2502     1  0 Sep24 ?        00:24:33 avahi-daemon: running [mongodb1.local]

root      2912     1  3 Sep24 ?        2-13:06:11 /home/mongodb/mongodb-linux-x86_64-2.4.9/bin/mongos --configdb 192.168.12.220:27000 -port 45000 -chunkSize 1024 --logpath /home/mongodb/data/mongost.log -fork   ---这个肯定是mongos了
root     23851  1890  0 14:13 pts/0    00:00:00 ./mongo 127.0.0.1:45000
root     24368 24349  0 14:20 pts/1    00:00:00 grep mongo

同时可以看到数据的存放目录
/home/mongodb/data/shard1t   ---29017
/home/mongodb/data1/shard2t  ---29018

[root@mongodb1 ~]# df -ah

none                     0     0     0   -  /proc/sys/fs/binfmt_misc
sunrpc                   0     0     0   -  /var/lib/nfs/rpc_pipefs

根据要求，我们可以这样建立：
/home/mongodb/data/shard1t   ---29017
/home/mongodb/data1/shard2t  ---29018
/home/mongodb/data1/shard2n  ---29019   ---这个目录是之前那个挂掉的分片使用的，我们可以继续沿用

下面可以开始删除原始数据了

删除数据：
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*

删除配置目录下内容：
cd /home/mongodb/data/configt/



可以重新搭建新环境了：

启动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

启动mongos：

启动三个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
