不多说,直接上干货!

说在前面的话

   首先,查看下你的操作系统的版本。

root@zhouls-virtual-machine:~# cat /etc/issue
Ubuntu 14.04. LTS \n \l root@zhouls-virtual-machine:~#

  我的是Ubuntu 14.04.4

  我的环境在Ubuntu14.04下搭建,注意:不同版本之间可能存在兼容性(其他的如16.04,我也暂时测试过)

Ubuntu16.04下Mongodb安装部署步骤(图文详解)

root@zhouls-virtual-machine:~# mongo
The program 'mongo' is currently not installed. You can install it by typing:
apt-get install mongodb-clients
root@zhouls-virtual-machine:~#

  这里,建议大家不要直接就输入apt-get install mongodb-clients来安装。

这样有两点问题:

  1.安装的是客户端

  2.版本问题,这个很重要,项目中mongo数据库用的是2.6,而apt-get自动安装的根本不知道是什么版本,而mongodb不同版本之间是不能兼容的。所以如果根据需要是迁移数据库之类的,这样到后面会有超级一大堆的错误。

Mongodb安装包的下载

 mongo官网下载地址 (进入)

根据自己的需要选择版本下载,需要注意亮点:

  1.大版本保持一致,因为大版本之间不兼容

  2.mongodb亦按照基数版本不稳定的规则,一般用于生产环境的都是偶数版本,如果安装的是基数(例如2.7),进入时会出现一下提示。

  我这里,就选择最简单的和免费的,社区服务版本。

   我一般喜欢用tar.gz来下载安装,当然大家也可以选择用rpm方式来安装。

  我这里,先暂时是,放在/home/zhouls/Downloads/下

  mongodb不需要像别的数据库那样配置解压后放到/usr/local

  但是为了方便管理,最好还是放到usr/local下面。

  命令如下:

root@zhouls-virtual-machine:~/Downloads# ls
mongodb-linux-x86_64-ubuntu1604-3.4.4 vmware-tools-distrib
mongodb-linux-x86_64-ubuntu1604-3.4.4.tgz
root@zhouls-virtual-machine:~/Downloads# mv mongodb-linux-x86_64-ubuntu1604-3.4.4 /usr/local/mongodb
root@zhouls-virtual-machine:~/Downloads# cd /usr/local
root@zhouls-virtual-machine:/usr/local# pwd
/usr/local
root@zhouls-virtual-machine:/usr/local# ls
bin etc games include lib man mongodb sbin share src
root@zhouls-virtual-machine:/usr/local#

  初步认识下,mongdb的目录结构

root@zhouls-virtual-machine:/usr/local/mongodb# pwd
/usr/local/mongodb
root@zhouls-virtual-machine:/usr/local/mongodb# ls
bin GNU-AGPL-3.0 MPL-2 README THIRD-PARTY-NOTICES
root@zhouls-virtual-machine:/usr/local/mongodb#

  然后为了mongodb创建存储数据的文件目录和日志文件目录

root@zhouls-virtual-machine:/usr/local/mongodb# pwd
/usr/local/mongodb
root@zhouls-virtual-machine:/usr/local/mongodb# ls
bin GNU-AGPL-3.0 MPL-2 README THIRD-PARTY-NOTICES
root@zhouls-virtual-machine:/usr/local/mongodb# mkdir data
root@zhouls-virtual-machine:/usr/local/mongodb# mkdir log
root@zhouls-virtual-machine:/usr/local/mongodb# ls
bin data GNU-AGPL-3.0 log MPL-2 README THIRD-PARTY-NOTICES
root@zhouls-virtual-machine:/usr/local/mongodb#

  进入到mongodb下面的bin里面查看mongodb帮助文档

root@zhouls-virtual-machine:/usr/local/mongodb# pwd
/usr/local/mongodb
root@zhouls-virtual-machine:/usr/local/mongodb# ls
bin data GNU-AGPL-3.0 log MPL-2 README THIRD-PARTY-NOTICES

找到参数

启动 MongoDB数据库

  使用下列命令启动 mongod 进程。

sudo service mongod start

或者

  启动数据库(推荐)

./mongod --dbpath=/usr/local/mongodb/data/ --fork --logpath=/usr/local/mongodb/log

  --dbpath=/usr/local/mongodb/data/ 用于指定存放的mongodb数据库

  --fork 是后台执行,不然一直在前台

  --logpath=/usr/local/mongodb/log用于指定mongodb的日志记录文件

mongodb启动时报错ERROR: child process failed, exited with error number 1

检查 MongoDB 是否成功启动

  通过检查 /var/log/mongodb/mongod.log 文件来确定 mongod 进程是否已经成功启动。 
或者查看进程

ps -ef | grep mongod

 

root@zhouls-virtual-machine:~# ps -ef | grep mongod
root 6072 4783 1 11:09 ? 00:00:01 ./mongod --dbpath=/usr/local/mongodb/data/ --fork --logpath=/usr/local/mongodb/log
root 6138 6126 0 11:12 pts/11 00:00:00 grep --color=auto mongod
root@zhouls-virtual-machine:~#

启动后即可通过mongo命令进入数据库

  如果大家按照上面的步骤来,安装之后,还是出现这样的情况的话,则那么直接,用apt install mongodb-clients吧。

  

停止 MongoDB

sudo service mongod stop

重新启动 MongoDB

sudo service mongod restart
