mongodb 安装

作为一个前端开发,操作数据库太过困难了,而 mongo 的操作语法就是 json,对前端非常友好,对于我这种技术水平,肯定是非常合适的。

至于 mongo 是 NoSQL(not only sql)等优点就不多做介绍了,可以今天记录一下安装 mongo 的过程和遇到的一些问题。

先去官网下载:https://www.mongodb.com/

选择社区版,具体哪个版本是最稳定,用的最多的,还真是不清楚,稳一点就选择 4.x,因为公司就在用这个版本,我直接选择最新的:

安装的时候就只需要注意几点,一个是 custom,自定义安装路径,另一个是 data directory 和 log directory,这两个是数据库的存放路径和 log 路径:

安装成功之后,浏览器访问http://localhost:27017

如果有输出:
It looks like you are trying to access MongoDB over HTTP on the native driver port.

那就是安装成功了,我选的是 7.0,默认安装了 mongodb compass,其它版本好像是可以选择是否安装,不勾选就不会(不知道是不是我没注意),mongodb compass 是一个可视化工具,也可以下载 mongo 那边的 tools 单独下载。

当我安装成功之后,命令行运行 mongo 会报错命令不存在,运行 mongod 会有一堆报错:

然后就说是 dbpath 没配置对:

{"error":"NonExistentPath: Data directory C:\\data\\db\\ not found. Create the missing directory or specify another path using (1) the --dbpath command line option, or (2) by adding the 'storage.dbPath' option in the configuration file."}}

但是 mongod.cfg 里面配置的是有的,就一顿折腾,各种指定 dbpath 和新建 data/db,和配置 mongod 系统路径,但是用浏览器看是启动了,可视化工具也能连接:

最后发现 MongoDB 是从 MongoDB 5.0 版本开始在命令行环境使用 mongosh 命令来控制和操作 MongoDB 的。是在这个地址找到的,提到了这一点,且,没有专门配置环境变量:

在早期的 MongoDB 版本中,通常使用 mongo 或者 mongod 命令,所以在下载 mongo 的地方选择 tools,下载安装 mongosh:

admin/config/local 是默认就有的,每一个相当于 MySQL 的数据库,里面新建 Collection 相当于 MySQL 的表。

至此,mongodb 安装完成,就可以开始自己本地开始随便学习了。
