安装

curl -fsSL https://code-server.dev/install.sh | sh

编辑配置文件,放开监听端口

vi ~/.config/code-server/config.yaml
ufw allow

开机启动

sudo systemctl enable --now code-server@$USER

手工启动

code-server

1. 在控制台添加函数

   (function(console){
       console.save = function(data, filename){
           if(!data) {
               console.error('Console.save: No data')
               return;
           }
          if(!filename) filename = 'console.json'
           var blob = new Blob([data], {type: 'text/json'}),
               e    = document.createEvent('MouseEvents'),
               a    = document.createElement('a')
           a.download = filename
           a.href = window.URL.createObjectURL(blob)
           a.dataset.downloadurl =  ['text/json', a.download, a.href].join(':')
           e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
           a.dispatchEvent(e)
       }
   })(console)

2. 执行导出

   console(temp1,1.txt)

1. rclone安装

   curl https://rclone.org/install.sh | sudo bash

2. oracle cloud客户密钥申请

   • 登陆oracle cloud，右上角进入 “我的概要信息”
   • 选择客户密钥并生成，输入名称后生成secret_access_key，复制保存
   • 返回后界面获取访问密钥access_key_id

3. 获取存储桶信息及区域
   查看存储桶详细，获取“名称空间”(Namespace)
   区域即存储桶所在区域，比如韩国春川(ap-chuncheon-1)

4. rclone配置
   按照客户密钥及存储桶信息生成配置。在ubuntu环境下，rclone的配置文件位于"～/.config/rclone/rclone.conf",在一个环境配置好后，可直接复制文件到相应位置

   rclone config

   按提示依次输入信息，输入完后配置项及说明如下如下：

   #cloud为rclone config中输入到配置名称
   [cloud] 
   type = s3
   provider = Other
   access_key_id = 
   secret_access_key = 
   # 替换Namespace及ap-chuncheon-1
   endpoint = https://Namespace.compat.objectstorage.ap-chuncheon-1.oraclecloud.com
   acl = private
   region = ap-chuncheon-1
   bucket_acl = private

5. 挂载/卸载本地目录

   • 挂载(cloud为配置到名称)

     rclone mount cloud:/ 本地目录 --copy-links --allow-other --allow-non-empty --umask 000 --daemon

   • 卸载

     fusermount -qzu 本地目录

6. 其他常用操作

   • 不挂载查看文件

     rclone ls cloud:/

apt update;apt upgrade -y;
apt-get install software-properties-common -y
apt-get install git libpulse-dev autoconf m4 intltool dpkg-dev libtool libsndfile-dev libcap-dev libjson-c-dev -y
apt-get build-dep pulseaudio -y
chmod 777 pul*.dsc
apt source pulseaudio
cd pulseaudio-13.99.1
./configure
cd ../
git clone https://github.com/neutrinolabs/pulseaudio-module-xrdp.git
cd pulseaudio-module-xrdp
./bootstrap
./configure PULSE_DIR="/root/pulseaudio-13.99.1"
make
cd src/.libs
install -t "/var/lib/xrdp-pulseaudio-installer" -D -m 644 *.so
install -t "/usr/lib/pulse-13.99.1/modules" -D -m 644 *.so
reboot

cdn.bootcss.com域名已变更

可调整为如下两个源：

• cdn.bootcdn.net/ajax/libs
• cdnjs.cloudflare.com/ajax/libs

蚂蚁笔记修改如下文件

• src\github.com\leanote\leanote\app\views\note\note-dev.html
• src\github.com\leanote\leanote\app\views\note\note.html
• src\github.com\leanote\leanote\public\libs\md2html\md2html.js

• 安装MongoDB

  wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
  echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
  apt-get update
  apt-get install -y mongodb-org
  systemctl start mongod

• 备份还原数据库

  • 备份

    mongodump --port 27017 --db leanote -o /data/leanoteBackUp/      

  • 还原

    mongorestore -h 127.0.0.1:27017 -d leanote /developer/data/leanoteBackUp/leanote -u=root -p=xxxx

• 覆盖原src目录

1. rndc生成配置文件

   rndc-confgen > /etc/rndc.conf

2. 密钥覆盖到 /etc/rndc.key

3. named配置文件调整

   • 添加key包含
   • 参照/etc/rndc.conf添加权限控制

4. 刷新域名

   rndc freeze example.com
   rndc thaw example.com

#!/bin/bash
echo root:password |sudo chpasswd root
sudo sed -i 's/^#\?PermitRootLogin.*/PermitRootLogin yes/g' /etc/ssh/sshd_config;
sudo sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication yes/g' /etc/ssh/sshd_config;
sudo service sshd restart

1. 安装

   yum -y install bind bind-chroot bind-utils

2. 生成更新密钥

   //采用HMAC-MD5
   dnssec-keygen -a HMAC-MD5 -b 128 -n USER dnskey
   //采用HMAC-SHA1，go-nsupdate不支持HMAC-MD5
   dnssec-keygen -a HMAC-SHA1 -T KEY -b 128 -n USER dnskey

3. 调整监听端口及密文

   vi /etc/named.conf   
   key "dnskey" {
       algorithm hmac-md5;
       //algorithm hmac-sha1;
       secret "secret_key";
   }

4. 添加域名

   vi /etc/named.rfc1912.zones
   zone "test.cn" IN {
       type master;
       file "named.test";
       allow-update { key dnskey; };
   };

5. 添加域名配置并修改信息

   cp /var/named/named.localhost /var/named/named.test

6. 重启named

   systemctl restart named

7. 客户端更新

   nsupdate -y dnskey:secret_key
   //nsupdate默认为hmac-md5，非该类型要指定加密方式
   //nsupdate -y hmac-sha1: dnskey:secret_key
   > server x.x.x.x
   > update add test.cn 86400 A 3.3.3.3
   > send
   > quit
   //go-nsupdate 更新
   ./go-nsupdate -i enp0s3  --server=x.x.x.x  --interface-family=ipv4 --tsig-algorithm=hmac-sha1 --tsig-name=dnskey --tsig-secret=secret_key --zone=test.cn a1.test.cn -v

8. 核对记录

   dig @X.X.X.X test.cn

9. 查看日
