1 描述

mongodb entriprise3.2手册中支持RHEL7系统，因此选择最小化安装OEL7U2 x64位操作系统，根据mongodb手册，使用yum命令安装与卸载mongodb enterprise。（本文mongodb enterprise版本为3.2.8）

利用yum安装的mongodb实际是按照redhat的管理系统的风格将mongodb的相关文件放在了操作系统的各个对应目录下。可通过rpm -qpl 命令查看软件包的安装位置。本质mongodb的命令集与tarball打包的一样。只不过将mongodb命令分组归类到几个rpm包里。

使用操作系统service管理方式启动mongodb实际是调用的mongod, 关闭mongodb是利用的kill命令。

2 过程设计

最小化安装操作系统

配置网络

禁用selinux

配置yum安装源

创建mongod用户

使用yum命令安装mongodb enterprise

使用yum命令卸载mongodb enterprise

3 详细步骤操作

3.1 最小化安装操作系统（略）

3.2 配置网络（略）

3.3 禁用selinux（略）

3.4 配置yum安装源

3.4.1 Mongodb官网文档提供的yum源

[root@localhost ~]# cat /etc/yum.repos.d/mongodb-enterprise.repo

[mongodb-enterprise]

name=MongoDB Enterprise Repository

baseurl=https://repo.mongodb.com/yum/redhat/$releasever/mongodb-enterprise/stable/$basearch/

gpgcheck=1

enabled=1

gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc

3.4.2 以本地操作系统iso作为yum源

[root@localhost ~]# cat /etc/yum.repos.d/public-yum-ol7.repo

[rhel_7_iso]

name=local iso

baseurl=file:///mnt/cdrom/

gpgcheck=1

gpgkey=file:///mnt/cdrom/RPM-GPG-KEY-oracle

3.5 创建mongod用户

[root@localhost ~]# useradd mongod

[root@localhost ~]# passwd mongod

Changing password for user mongodb.

New password:

BAD PASSWORD: The password contains the user name in some form

Retype new password:

passwd: all authentication tokens updated successfully.

[root@localhost ~]#

3.6 使用yum命令安装mongodb enterprise

[mongod@localhost ~]$ sudo yum install -y mongodb-enterprise

We trust you have received the usual lecture from the local System

Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.

#2) Think before you type.

#3) With great power comes great responsibility.

[sudo] password for mongod:

3.7 使用yum命令卸载mongodb enterprise

要完全删除mongodb ，需要删除mongodb 应用软件包，配置文件，数据文件和日志文件。如下：

3.7.1 停止数据库

[mongod@localhost ~]$ sudo service mongod stop

[sudo] password for mongod:

Stopping mongod (via systemctl): [ OK ]

[mongod@localhost ~]$

3.7.2 删除应用软件包

[mongod@localhost ~]$ sudo yum erase $(rpm -qa | grep mongodb-enterprise)

4.1.1 mongodb相关文件

默认安装情况下 mongodb instance 数据文件目录为/var/lib/mongo , 日志文件目录为/var/log/mongodb . mongodb instance 操作系统进程由mongod 用户运行。如果想改变数据文件目录和日志文件目录，可以修改/etc/mongod.conf中的 systemLog.path和storage.dbPath参数。

默认/var/lib/mongo与/var/log/mongodb目录属组为mongod,如果改变mongodb instance运行用户，记得数据文件目录与日志文件目录属组一并修改。

5.1.3 本地mongo shell连接数据库

在数据库启动后，使用mongo shell连接数据（mongo shell默认连接本地的test数据库）

[mongod@localhost ~]$ mongo

MongoDB shell version: 3.2.8

connecting to: test

Server has startup warnings:

2016-08-11T21:02:32.308-0400 I CONTROL [initandlisten]

2016-08-11T21:02:32.308-0400 I CONTROL [initandlisten] ** WARNING: soft rlimits too low. rlimits set to 4096 processes, 64000 files. Number of pr

ocesses should be at least 32000 : 0.5 times number of files.MongoDB Enterprise > show dbs

local 0.000GB

MongoDB Enterprise > exit

bye

[mongod@localhost ~]$

5.1.4 网络连接数据库

MongoDB连接远程服务器的命令格式如下:

mongo 远程主机ip或DNS:MongoDB端口号/数据库名 -u user -p password

由于本文数据库参数mongodb.conf为初始配置，初始只允许本机访问，需修改bind_id 值为0.0.0.0 , 重启mongodb , 关闭系统防火墙或添加允许访问端口。

[root@localhost ~]# systemctl disable firewalld

Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

[root@localhost ~]# systemctl stop firewalld

或开放系统27017端口

[root@localhost ~]# iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 27017 -j ACCEPT

远程连接测试

远程机器使用mongo shell连接数据库(远程机器为windows机器，使用mongo shell 访问mongodb 172.16.196.149 )

C:\Program Files\MongoDB\Server\3.2\bin>mongo.exe 172.16.196.149

2016-08-19T15:07:31.587+0800 I CONTROL [main] Hotfix KB2731284 or later update

is not installed, will zero-out data files

MongoDB shell version: 3.2.9

connecting to: 172.16.196.149/test

Server has startup warnings:

2016-08-11T21:02:32.308-0400 I CONTROL [initandlisten]

2016-08-11T21:02:32.308-0400 I CONTROL [initandlisten] ** WARNING: soft rlimits

too low. rlimits set to 4096 processes, 64000 files. Number of processes should

be at least 32000 : 0.5 times number of files.
