1、官网下载tar包:

https://www.mongodb.com/download-center#community

2、解压

tar -xf mongodb-linux-x86_64-rhel70-3.6.5.tgz && mv mongodb-linux-x86_64-rhel70-3.6.5 /usr/local/mongodb

3、创建数据、日志、配置文件目录；创建用户、授权

mkdir -p /usr/local/mongodb/{data,log,conf}

4、编写配置文件

vim /usr/local/mongodb/conf/mongod.conf

systemLog:

  destination: file

  path: /usr/local/mongodb/log/logs

  logAppend: true

storage:

  journal:

    enabled: true

  dbPath: /usr/local/mongodb/data

  directoryPerDB: true

  engine: wiredTiger

  wiredTiger:

    engineConfig:

      cacheSizeGB: 16

      directoryForIndexes: true

    collectionConfig:

      blockCompressor: zlib

    indexConfig:

      prefixCompression: true

net:

  port: 27017

processManagement:

  fork: true

5、创建用户、授权

useradd mongod

chown -R mongod:mongod /usr/local/mongodb/

5、启动mongodb

/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongod.conf

6、编写启动脚本

vim /lib/systemd/system/mongodb.service

[Unit]

Description=mongodb

After=network.target remote-fs.target nss-lookup.target

[Service]

Type=forking

ExecStart=/usr/local/mongodb/bin/mongod --config  /usr/local/mongodb/conf/mongod.conf

ExecReload=/bin/kill -s HUP $MAINPID

ExecStop=/usr/local/mongodb/bin/mongod --shutdown --config /usr/local/mongodb/conf/mongod.conf

PrivateTmp=true

[Install]

WantedBy=multi-user.target

7、加执行权限：

chmod 754 /lib/systemd/system/mongodb.service

8、启动关闭服务，设置开机自启

systemctl start mongodb.service   

systemctl stop mongodb.service   

#开机启动   

systemctl enable mongodb.service

9、centos 6开机自启和启动脚本

vim /etc/rc.d/init.d/mongodb

#!/bin/bash

 #chkconfig: 2345 80 90

 #description: mongodb

 start() {

  /usr/local/mongodb/bin/mongod --config /usr/local/mongodb/conf/mongod.conf

 }

 stop() {

  /usr/local/mongodb/bin/mongod --config /usr/local/mongodb/conf/mongod.conf --shutdown

 }

 case "$1" in

   start)

  start

  ;;

 stop)

  stop

  ;;

 restart)

  stop

  start

  ;;

   *)

  echo 

 $"Usage: $0 {start|stop|restart}"

  exit 1

 esac

10、设置开机自启

chmod +x /etc/rc.d/init.d/mongod

chkconfig --add mongod

chkconfig --level 345 mongod on

chkconfig --list mongod

service mongodb start
