1.安装MongoDB
mongoDB的tar包下载地址：https://www.mongodb.com/download-center#atlas
解压安装包 tar -zxvf xxxxxxxxxx.tar
移动到安装目录 mv mongodb-linux-x86_64-xxx /usr/local/mongodb
添加环境变量 echo "export PATH=\$PATH:/usr/local/mongodb/bin【解压后移动过去会存在一个目录，所以需要配置】" > /etc/profile.d/mongodb.sh （这个里面要小心了！）
使环境变量生效 source /etc/profile.d/mongodb.sh
创建Mongodb用户和组 useradd -r -M -s /sbin/nologin mongod
***创建启动数据库和启动日志 mkdir -p /data/mongodb/{db,log}/
修改权限 chown -R mongod:mongod/data/mongodb/
配置mongoDB配置文件： vi /etc/mongod.conf
#mongod.conf
#for documentation of all options, see:
# http://docs.mongodb.org/manual/reference/configuration-options/
#where to write logging data.
systemLog:
destination: file
logAppend: true
path: /data/mongodb/log/mongod.log
#Where and how to store data.
storage:
dbPath: /data/mongodb/db
journal:
enabled: true
# engine:
# mmapv1:
# wiredTiger:
#how the process runs
processManagement:
fork: true # fork and run inbackground
pidFilePath: /var/run/mongodb/mongod.pid # location of pidfile
#network interfaces
net:
port: 27017
bindIp: 127.0.0.1 # Listen tolocal interface only, comment to listen on all interfaces.
#security:

备注：
如果MongoDB端口不在27017-27019,28017-28019之间，需要执行以下步骤：
# yum -y install policycoreutils-python
# semanage port -a -t mongod_port_t -p tcp
创建MongoDB自启动脚本 vi /etc/init.d/mongod
#!/bin/bash
#mongod - Startup script for mongod
#chkconfig: 35 85 15
#description: Mongo is a scalable, document-oriented database.
#processname: mongod
#config: /etc/mongod.conf
#pidfile: /var/run/mongodb/mongod.pid
./etc/rc.d/init.d/functions
#things from mongod.conf get there by mongod reading it
#NOTE: if you change any OPTIONS here, you get what you pay for:
#this script assumes all options are in the config file.

设置MongoDB服务开机自启动
chmod +x /etc/init.d/mongod
chkconfig mongod on
启动MongoDB服务
service mongod start
如果启动不成功：
主要查看 启动脚本 .sh 文件中的配置的环境变量是否正确， 同时查看db log的权限是否是脚本中配置的用户和组，同时可执行，我给的777
验证启动成功：
service mongod status
