CentOS Linux release 7.8.2003 (Core)
# 禁用防火墙
[root@wan ~]# systemctl stop firewalld
[root@wan ~]# systemctl disable firewalld
# 禁用selinux
[root@wan ~]# vim /etc/selinux/config
SELINUX=disable

[root@wan ~]# yum install wget bash-completion lrzsz tree zip unzip psmisc net-tools vim -y
# 配置扩展源
[root@wan ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

二、yum 安装

配置mingdb yum安装源

[root@node01 ~]# vim /etc/yum.repos.d/mongodb-enterprise-4.2.repo
[mongodb-enterprise-4.2]
name=mongodb-enterprise-4.2
baseurl=https://repo.mongodb.com/yum/redhat/7Server/mongodb-enterprise/4.2/x86_64
gpgcheck=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.2.asc

[root@node01 ~]# yum list | grep -i mongodb

安装mongodb

[root@node01 ~]# yum install mongodb-enterprise-4.2.8 -y

启动mongodb服务

[root@node01 ~]# systemctl enable --now mongod
[root@node01 ~]# netstat -lnutp | grep mongod
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      12083/mongod

登录数据库

[root@node01 ~]# mongo
MongoDB shell version v4.2.8
MongoDB Enterprise > 
MongoDB Enterprise > db
test
MongoDB Enterprise > show dbs
admin   0.000GB
config  0.000GB
local   0.000GB
MongoDB Enterprise > exit
bye
[root@node01 ~]# 

二、源码安装

# 上传源码包
[root@node02 ~]# ll mongodb-linux-x86_64-rhel70-4.2.8.tgz 
-rw-r--r--. 1 root root 132768194 Feb 14 19:07 mongodb-linux-x86_64-rhel70-4.2.8.tgz

# 解压到指定目录
[root@node02 ~]# tar xf mongodb-linux-x86_64-rhel70-4.2.8.tgz -C /usr/local/
[root@node02 ~]# cd /usr/local/
[root@node02 local]# ln -sv mongodb-linux-x86_64-rhel70-4.2.8/ mongodb
‘mongodb’ -> ‘mongodb-linux-x86_64-rhel70-4.2.8/’

# 创建存放数据、日志、pid文件的目录
[root@node02 ~]# mkdir -p /var/log/mongodb /var/run/mongodb /var/lib/mongo

# 提供配置文件
[root@node02 local]# vim /etc/mongod.conf 
# where to write logging data.
