最近公司使用到了 mongodb ，很久没有使用过了，记录一下安装步骤吧，方便以后安装使用。

安装包说明：

mongodb-org

完整包，包含下面4个安装包

mongodb-org-server

包含mongod的进程，启动配置和初始化脚本

mongodb-org-mongos

包含mongod的进程.

mongodb-org-shell

Mongo shell

mongodb-org-tools

MongoDB tools: mongoimport bsondump, mongodump,mongoexport, mongofiles, mongooplog, mongoperf, mongorestore, mongostat, and mongotop.

Mongodb 安装使用说明：

1、创建一个yum 源

vi /etc/yum.repos.d/mongodb-org-3.2.repo

在repo 文件中添加

[mongodb-org-3.2]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc

2、安装yum

sudo yum install -y mongodb-org

如果需要指定版本，也可以这么安装

sudo yum install -y mongodb-org-3.2.6 mongodb-org-server-3.2.6 mongodb-org-shell-3.2.6 mongodb-org-mongos-3.2.6 mongodb-org-tools-3.2.6

由于公司的网络一直有问题，最后选择了 rpm 包安装。

[root@new-cdh1 mongodbsoft]# rpm -ivh mongodb-org-*
warning: mongodb-org-3.2.6-1.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID ea312927: NOKEY

3:mongodb-org-server ########################################### [ 60%]
4:mongodb-org-mongos ########################################### [ 80%]
5:mongodb-org ########################################### [100%]

3、启动 mongodb

sudo service mongod start
[root@new-cdh1 mongo]# service mongod start
Starting mongod: [ OK ]
[root@new-cdh1 mongo]#

4、添加开机启动

[root@new-cdh1 mongo]# chkconfig mongod on

完全卸载mongod

1、停止mongod

[root@new-cdh1 ~]# service mongod stop
Stopping mongod: [ OK ]
[root@new-cdh1 ~]# chkconfig mongod off

2、卸载安装包

[root@new-cdh1 ~]# yum erase $(rpm -qa | grep mongodb-org)
