创建资源和连接云服务器
之前写过，这次不写。
安装MongoDB
1.安装MongoDB。yum -y install mongodb mongodb-server.x86_64 mariadb-devel.i686
代码解释：yum -y依然是在线下载，后面接的是包名
之后代码显示如下：
Dependency Updated:

Complete!2.启动MongoDB服务。systemctl start mongod
代码解释：systemctl start作用是启动xx服务，这里接的是mongod，在之前的学习里有docker。
3.查看MongoDB运行状态。systemctl status mongod
代码解释：systemctl status用来查询服务运行状态
之后代码显示如下：

1.下载Leanote二进制安装包。wget https://nchc.dl.sourceforge.net/project/leanote-bin/2.6.1/leanote-linux-amd64-v2.6.1.bin.tar.gz
之后代码显示如下：

代码解释：
tar是Unix和类Unix系统上的压缩打包工具，可以将多个文件合并为一个文件，打包后的文件后缀亦为“tar”。tar -zxvf file.tar.gz 用来解压 tar.gz
3.编辑文件leanote/conf/app.conf。
- 使用vim编辑器打开文件leanote/conf/app.conf。
vim leanote/conf/app.conf - 输入
:/app.secret=并按下回车查找app.secret位置。 - 按下
i键进入编辑模式，修改该项的值为任意字符串。 - 修改完成后，按下esc键退出编辑模式，输入
:wq保存并退出。
4.初始化数据库。
mongorestore -h localhost -d leanote --dir /root/leanote/mongodb_backup/leanote_install_data/
代码解释：
--dir 后面为解压后的leanote中的路径，可将其改为自己对应的路径
之后代码显示如下：
2020-09-24T20:36:34.736+0800 /root/leanote/mongodb_backup/leanote_install_data/group_users.bson
