MongoDB安装

MongoDB安装

1.上传mongodb包

[root@long ~]# ll
-rw-r--r-- 1 root root 100351280 Jul  6  2019 mongodb-linux-x86_64-3.6.13.tgz

2.文件放于/usr/local/mongodb目录下

cd /usr/local
tar xf mongodb-linux-x86_64-3.6.13.tgz   #解压文件
mv mongodb-linux-x86_64-3.6.13/ /usr/local/mongodb  #移动文件

3.配置环境变量

vi /etc/profile  

export MONGODB_HOME=/usr/local/mongodb  
export PATH=$PATH:$MONGODB_HOME/bin  

4.mongdb启动配置

#创建db和log目录
  cd /usr/local/mongodb
  mkdir data
  cd data
  mkdir db
  mkdir log

#进入mongodb的bin目录，配置文件可以自定义位置，我就把它放在了bin目录下
  cd /usr/local/mongodb/bin

[root@long bin]# vim mongodb.conf 

dbpath = /usr/local/mongodb/data/db #数据文件存放目录  
logpath = /usr/local/mongodb/logs/mongodb.log #日志文件存放目录  
port = 27017  #端口  
fork = true  #以守护程序的方式启用，即在后台运行  
#nohttpinterface = true 
#网上很多添加这句nohttpinterface=true，但是启动会报错，所以就去掉了

加上nohttpinterface = true启动报错提示如下:
[root@long bin]# ./mongod -f mongodb.conf
Error parsing INI config file: unrecognised option 'nohttpinterface'
try './mongod --help' for more information

注释掉后启动
[root@long bin]# ./mongod -f ./mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 8092
child process started successfully, parent exiting

[root@long bin]# ps aux|grep mongo

root      8173  0.0  0.0 112660   968 pts/0    R+   11:03   0:00 grep --color=auto mongo

5.进入mongo

[root@long bin]# ./mongo
