1、创建mongodb的管理用户
注意：有必要强调的是，LINUX版本最好是6.4以上，在REDHAT5.5上，我尝试安装，最后要求GLIBC版本最低是2.10，要升级GLIBC，风险很大。
[root@mongo ~]# uname -a
Linux mongo 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@mongo ~]#
[root@mongo ~]#useradd -u 500 mongo
[root@mongo ~]#passwd mongo2、创建mongodb的安装目录
[root@mongo ~]# cd /opt/mongo/
[root@mongo ~]#chown -R mongo:mongo /opt/mongo
[root@mongo ~]#chmod -R 775 /opt/mongo
[mongo@mongo mongo]$ ls
soft
[mongo@mongo mongo]$ mkdir data
[mongo@mongo mongo]$ ls
data soft
[mongo@mongo mongo]$ mkdir logs
[mongo@mongo mongo]$ ls
data logs soft
[mongo@mongo mongo]$ ls -l
total 12
drwxrwxr-x. 2 mongo mongo 4096 Jun 11 01:08 data #MongoDB的数据文件存放目录
drwxrwxr-x. 2 mongo mongo 4096 Jun 11 01:08 logs #MongoDB的日志文件存放目录，类似ORACLE的ALERT日志文件
drwxrwxr-x. 2 mongo mongo 4096 Jun 11 01:08 soft #MongoDB的软件安装目录3、mongodb管理用户登录服务器，上传安装介质并解压
注意：这里需要强调，MongoDB的安装版本必须对应特定的操作系统平台及版本，这里我用 mongodb-linux-x86_64-rhel62-3.2.7.tgz
[mongo@mongo ~]$ cd /opt/mongo/
[mongo@mongo mongo]$ ls
mongodb-linux-x86_64-rhel62-3.2.7.tgz

[mongo@mongo ~]$mv mongodb-linux-x86_64-rhel62-3.2.7 soft4、修改管理用户下的环境变量
[mongo@mongo ~]$ cat .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
export PATH=$PATH:/opt/mongo/soft/bin
export MONGO_BASE=/opt/mongo
export MONGO_DATA=/opt/mongo/data
export MONGO_LOGS=/opt/mongo/logs5、检查mongo对glibc的要求
注意：这里要求GLIBC版本号必须大于等于2.10
[root@mongo ~]# rpm -qi glibc

Summary : The GNU libc libraries
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.6、解决libssl.so.10问题
通过mongod的可用性发现 libssl.so.10问题，此问题不解决，MongoDB无法启动
[mongo@mongo ~]$ mongod --help
mongod: error while loading shared libraries: libssl.so.10: cannot open shared object file: No such file or director
