下载
选择适合自己系统版本的安装包，本文安装环境CentOS 7.

MongoDB的官方网站是https://www.mongodb.com/，可以到官网上下载MongoDB的程序。之所以说是程序，是因为下载的安装包中MongoDB的相关程序已经编译好了，我使用的是mongodb-linux-x86_64-3.6.4.tgz ，可以在这个页面选择下载https://www.mongodb.com/download-center?jmp=nav#community。
```
[root@bigdata1 software]# cd /data/software/
[root@bigdata1 software]# wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.4.tgz
```

安装和配置

等待下载完成后解压，并更改文件夹名称为mongodb（可选）

[root@bigdata1 software]# tar -zxf mongodb-linux-x86_64-3.6.4.tgz
[root@bigdata1 software]# mv mongodb-linux-x86_64-3.6.4.tgz mongodb

在mongodb目录下创建数据库目录db、创建日志目录logs、创建配置文件目录conf

[root@bigdata1 software]# cd mongodb
[root@bigdata1 mongodb]# mkdir db
[root@bigdata1 mongodb]# mkdir logs
[root@bigdata1 mongodb]# mkdir conf
[root@bigdata1 mongodb]# ll
total 120
drwxr-xr-x. 2 root root   248 May  5 10:25 bin
drwxr-xr-x. 2 root root    26 May  5 10:48 conf
drwxr-xr-x. 4 root root  4096 May  5 10:55 db
-rw-r--r--. 1 root root 34520 Apr 13 23:37 GNU-AGPL-3.0
drwsr-xr-x. 2 root root    25 May  5 10:40 logs
-rw-r--r--. 1 root root 16726 Apr 13 23:37 MPL-2
-rw-r--r--. 1 root root  2195 Apr 13 23:37 README
-rw-r--r--. 1 root root 57190 Apr 13 23:37 THIRD-PARTY-NOTICES

在conf下新建配置文件mogodb.conf，并配置以下内容

[root@bigdata1 mongodb]# cd conf/
[root@bigdata1 conf]# touch mongodb.conf
[root@bigdata1 conf]# vi mongodb.conf

配置内容，如果提示nohttpinterface不存在，注释了就好了


#端口号，使用默认端口

port = 27017

#数据库目录

dbpath = /data/software/mongodb/db

#日志目录

logpath = /data/software/mongodb/logs/mongodb.log
logappend = true

#是否以守护进程的方式运行

fork = true

#是否关闭http管理接口


#nohttpinterface=true

直接的配置

#端口号，使用默认端口
port = 27017
#帮定ip
bind_ip = 10.153.4.555
#数据库目录
dbpath = /home/mongodb/mongodb-linux-x86_64-3.6.4/db
#日志目录
logpath = /home/mongodb/mongodb-linux-x86_64-3.6.4/logs/mongodb.log
#日志文件自动累加，而不是覆盖
logappend = true
#是否以守护进程的方式运行
fork = true
#是否关闭http管理接口,开启http后台管理页面
#nohttpinterface=true
~

也可这样启动

[root@slave08 mongodb-linux-x86_64-3.6.4]# cat startmongodbServer.sh
#!/bin/bash
./bin/mongod --dbpath /home/mongodb/mongodb-linux-x86_64-3.6.4/db --logpath /home/mongodb/mongodb-linux-x86_64-3.6.4/logs/mongodb.log --fork --port 27017 --bind_ip 10.153.4.230
[root@slave08 mongodb-linux-x86_64-3.6.4]# cat connectmongodbServershell.sh
#!/bin/bash
./bin/mongo 10.153.4.230:27017
[root@slave08 mongodb-linux-x86_64-3.6.4]#
也可以这样启动
[root@slave08 mongodb-linux-x86_64-3.6.4]# ./bin/mongod -f conf/mongodb.conf --repair

启动验证

启动

启动mongodb需要使用bin目录下的mongod，如果通过-f 或–config= 来指定配置文件

[root@bigdata1 conf]# cd /data/software/mongodb
[root@bigdata1 mongodb]# ./bin/mongod -f conf/mongodb.conf 
about to fork child process, waiting until server is ready for connections.
forked process: 6770
child process started successfully, parent exiting
[root@bigdata1 mongodb]# ps -ef | grep mongodb
root       6770      1 50 11:24 ?        00:00:51 ./bin/mongod -f conf/mongodb.conf
root       6800   1124  3 11:26 pts/0    00:00:00 grep --color=auto mongodb

连接mongodb需要使用bin目录下的mongo

[root@bigdata1 mongodb]# ./bin/mongo

正常关闭先通过shell连上服务器：
mongo
use admin
db.shutdownServer()

少用kill -9 或者15 pid 造成数据丢失。
