MongoDB是由C++编写，是一个开源的，基于分布式的，面向文档存储的非关系型数据库。是非关系型数据库当中功能最丰富、最像关系数据库的。

这里说得是yum安装，操作系统Centos7.1

1、配置MongoDByum源



vim /etc/yum.repos.d/mongodb-org-3.0.repo
-------------------------------------------------------------------------------
[mongodb-org-3.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.0/x86_64/
gpgcheck=0
enabled=1
------------------------------------------------------------------------------

yum clean all

yun makecache #清除yum缓存、建立数据缓存

2、安装



yum install -y mongodb-org

3、一些配置

MongoDB默认端口为：27017



添加防火墙规则：firewall-cmd --zone=public --add-port=27017/tcp --permanen
                firewall-cmd --reload
                firewall-cmd --list-all



调整selinux模式：Disabled
获取selinux模式：getenforce

vim /etc/selinux/config
SELINUX=disabled          #调整完需要重启设备

或者setenforce 0          #不需要重启设备

4、启动MongoDB



systemctl start mongod.service

进入mongo数据库

进入mongo会有如上报错信息，根据提示修改对应的配置文件


echo "mongod     soft    nofiles   64000" >> /etc/security/limits.conf
echo "mongod     soft    nproc     64000" >> /etc/security/limits.conf

echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo never > /sys/kernel/mm/transparent_hugepage/defrag

echo 0 > /proc/sys/vm/zone_reclaim_mode



重启数据库：systemctl restart mongod.service

至此：数据库搭建完成！！！
