获取mongodb安装包解压
[root@localhost ~]# wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-1.8.3-rc0.tgz
[monogdb@localhost ~]$ tar xzf mongodb-linux-x86_64-1.8.3-rc0.tgz
创建monogdb的数据存放位置并赋予monogdb相应的权限。
[root@localhost ~]# cd /opt
[root@localhost opt]# mkdir monogdata
[root@localhost opt]# ls
monogdata oracle software
[root@localhost opt]# chown monogdb:monogdb /opt/monogdata/
[root@localhost opt]# su - monogdb
[monogdb@localhost ~]$ mv mongodb-linux-x86_64-1.8.3-rc0 monogdb
[monogdb@localhost ~]$ cd monogdb/
[monogdb@localhost monogdb]$ cd bin/
[monogdb@localhost bin]$ ./mongod -dbpath /opt/monogdata/data/ --指定monogdb数据存放的位置。并开启monogdb的服务。
