MongoDB 3.2 for RHEL6.4 installation

简介:   从来不认为任何一门技术简单,尤其对于初次接触者;也许是因为开源,MongoDB不像Oracle数据库那么规范化,都有对应的详细的操作文档,按照文档来,就能达到目的,我觉得MongoDB在这方面差很多。

  从来不认为任何一门技术简单,尤其对于初次接触者;也许是因为开源,MongoDB不像Oracle数据库那么规范化,都有对应的详细的操作文档,按照文档来,就能达到目的,我觉得MongoDB在这方面差很多。下面,我以Oracle的安装思路总结下MongoDB的安装过程。
  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 mongo
 2、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 mongo]$ tar -xvf mongodb-linux-x86_64-rhel62-3.2.7.tgz

mongodb-linux-x86_64-rhel62-3.2.7/bin/mongo

[mongo@mongo ~]$mv mongodb-linux-x86_64-rhel62-3.2.7 soft
 4、修改管理用户下的环境变量
[mongo@mongo ~]$ 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/logs
  5、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

Name        : glibc                        Relocations: (not relocatable)

Version     : 2.12                              Vendor: Red Hat, Inc.

Release     : 1.107.el6                     Build Date: Tue 20 Nov 2012 08:22:45 PM PST

Install Date: Sat 11 Jun 2016 08:41:30 AM PDT      Build Host: x86-023.build.eng.bos.redhat.com

Group       : System Environment/Libraries   Source RPM: glibc-2.12-1.107.el6.src.rpm

Size        : 12947270                         License: LGPLv2+ and LGPLv2+ with exceptions and GPLv2+

Signature   : RSA/8, Tue 29 Jan 2013 07:00:11 AM PST, Key ID 199e2f91fd431d51

Packager    : Red Hat, Inc.

URL         : http://sources.redhat.com/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
 解决libssl.so.10问题,使用root建立软链接即可

[root@mongo lib]# pwd

/usr/lib

[root@mongo lib]# ls -l libss*

-rwxr-xr-x 1 root root 205052 Jul 20  2009 libssl3.so

lrwxrwxrwx 1 root root     23 Jun 11 11:36 libssl.so.10 -> /lib64/libssl.so.0.9.8e
 7、解决libcrypto.so.10问题
 通过mongod的可用性发现libcrypto.so.10问题,此问题不解决,MongoDB无法启动
 
解决libcrypto.so.10问题,使用root建立软链接即可

[root@mongo lib]# pwd

/usr/lib

[root@mongo lib]# ls -l libcryp*

-rw-r--r-- 1 root root   47750 Sep  4  2009 libcrypt.a

 9、启动mongodb数据库
[mongo@mongo ~]$ mongod --dbpath=$MONGO_DATA --logpath=$MONGO_LOGS/mongodb.log --logappend&

[1] 3028

[mongo@mongo ~]$
 10、检查mongodb的运行状态
[root@mongo mongo]# ps -ef|grep mongo

Welcome to the MongoDB shell.

 登录后,MongoDB要求关闭操作系统的transparent_hugepage特性(这里可以放在MongoDB安装前,系统调整时执行),需要以root身份执行以下命令:
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag
[root@mongo transparent_hugepage]# echo never > /sys/kernel/mm/transparent_hugepage/enabled
[root@mongo transparent_hugepage]# echo never > /sys/kernel/mm/transparent_hugepage/defrag
 12、重启MongoDB数据库并测试数据库可用性
[mongo@mongo ~]$ mongo
