Cloud probe

What is a cloud probe ？ Cloud probe , In fact, it is to use TCP, After a handshake connection to the server , Get the running status of the server .

This cloud probe , Use Nezha panel , Can realize to oneself （ More than one ） The server ：

• Support system status
• HTTP、TCP、Ping Monitoring and alarming
• Planning tasks
• Online terminals

probe

It is recommended that multi server users build , To improve security , Better prepare

• domain name ： Used to resolve domain name to Nezha panel （ Probe panel ）API Interface , At the same time, you can compile panel migration .
• CDN： The user resolves to the panel monitoring address , Opposite panel IP Protection , It is also convenient for migration .

This tutorial , The scheme used ： domain name +CDN+ The server .

Double 11 bought so many servers , Finally, it can be monitored in batches ～

You can monitor your servers in batches

Effect demonstration

In fact, Tencent cloud's console , The information is complete , You can also see the current... On the console CPU And bandwidth , Watch one at a time ：

Console

But it is always not intuitive , such as , An individual developer like me , There are several servers , You need to click one by one to view ：

When there are many servers

Probe function

This is the time , Our probe is set up , You can visually view ：

probe

Did you see my two servers at this time CPU It's full ？

Mainly , I'm compiling Android Source code , therefore CPU Run slowly , So the probe , It is also convenient for me to check whether the compilation is completed .

Log in online

Online login function , In fact, it is remote SSH. I know there are a lot of SSH Software for , such as ： Tencent cloud's online one click login 、Windows Of Powershell and Linux/macOS Of Terminal wait .

But the Nezha panel also provides one button SSH Sign in , The effect is similar to the online one click login of Tencent cloud ：

One click login

Login effect ：

Login successful

Of course , Such login , It's Secret free , Use the premise ：

• User login Nezha panel
• Yes Nginx Anti generation environment support

Don't talk much , Let's start the tutorial .

precondition

The first is the precondition , The basic requirements are simple ：

• At least one server
• Github or Gitee account number

Enhance the experience ：

• Two domain names （ No top-level domain name , Two secondary or tertiary domain names are sufficient ）
• CDN（ Tencent cloud is recommended CDN content distribution ）

Recently, double 11 , It is highly recommended that new users purchase servers ：https://curl.mintimate.cn/1jccDM8rK1S

Double eleven servers are recommended

here hypothesis I have prepared the domain name ：

• ops.mintimate.cn： Panel external domain name （ You can use CDN）
• nezha.mintimate.cn： Probe connection domain name （ Not to be used CDN）

Why do you do this ？ Draw a simple diagram ：

Why do I need two domain names

That is to say ：

• Panel external domain name （CDN） It is used for public network access ;
• Probe connection domain name （ Not to be used CDN）, It is used to receive probe data , It is convenient to migrate the panel in the future .

CDN analysis

Considering the use of CDN Little buddy , Not as many people as the server , Here is how to use Tencent cloud CDN analysis . First, log in to Tencent cloud CDN backstage ：https://console.cloud.tencent.com/cdn

after , Add a domain name here ：

Add domain name

Remember to configure Https, Increase security ：

To configure Https

Build panels

First we need to apply for a Oauth, Then the panel can be formally built , This server serves as the server where the panel is located and provides probes .

apply Oauth

apply Oauth, You can use GitHub, You can also use Gitee Of , Take one of the two ：

• GitHub：https://github.com/settings/developers
• Gitee： https://gitee.com/oauth/applications

In this paper, Gitee Method ,GitHub In fact, it's almost .

The permission can be set by default ：

Default permissions

among ：

• apply name ： at will , Just a code name. .
• Application description ： Ditto panel external domain name , It can be for IP, But it's not safe .
• App home ： As above, add the callback address to the external domain name in the panel , Nezha panel callback address is ：/oauth2/callback

After creating the app , obtain ：

• Client ID： client ID, The following text requires .
• Client Secret： Client key , The following text requires .
  The creation is complete

Remote connection

Here we use SSH Connect to our server remotely ：

Remote connection successful

Here I use the server oh-my-zsh, If you want to use , article ：Linux/Mac How to configure ZSH And use Oh-my-zsh？ Make your terminal more practical 、 beautiful

Run script

According to official website Project tips , We can use the one click installation script to install ：

curl -L https://cdn.jsdelivr.net/gh/naiba/[email protected]/script/install.sh -o nezha.sh && chmod +x nezha.sh
CN=true sudo ./nezha.sh

Note here , We'd better run the script in an empty folder , It is convenient to call up the script control interface later , such as ：

Run the installation script

after , Will ask if , We choose 1：

choice 1： Install the panel

After selection , Input Gitee（ If you use GitHub, Just hit enter ）：

choice Gitee

Last , Enter the client generated above ID And key ：

installation is complete

Here we are , The panel is installed . Actually , You can release 8008 After the port , The browser visited . But for the convenience of access 、 Security , Use Nginx Reverse proxy .

Be careful , This is the administrator account ：

The account number is the same as this one

Nginx Reverse proxy

Nginx Reverse proxy is too simple , But consider that many users use pagoda panels , So there is a two-step demonstration ：

• Conventional methods ： Use compile 、 Package manager or Docker Installed Nginx, Set up your own Nginx.conf.
• Pagoda method ： Use the pagoda to install Nginx.

If you don't know how to install Ngixn, Reference resources ： An article 、 There are three ways Debian Easy to install on Nginx

The domain name resolved here is the external domain name of the panel mentioned above （ You can use CDN）, This is what was assumed above ops.mintimate.cn. If it's Tencent cloud CDN, You can go to CDN Console Set up .

Conventional methods

Conventional methods , Create a new one conf, stay conf Add reverse proxy in ：

location /
{
	proxy_pass http://127.0.0.1:8008;
	proxy_set_header Host $host;
}
location ~ ^/(ws|terminal/.+)$
{
	proxy_pass http://127.0.0.1:8008;
	proxy_http_version 1.1;
	proxy_set_header Upgrade $http_upgrade;
	proxy_set_header Connection "Upgrade";
	proxy_set_header Host $host;
}

Nginx Set up

among ：

location ~ ^/(ws|terminal/.+)$
{
	proxy_pass http://127.0.0.1:8008;
	proxy_http_version 1.1;
	proxy_set_header Upgrade $http_upgrade;
	proxy_set_header Connection "Upgrade";
	proxy_set_header Host $host;
}

For remote terminal function , need Nginx Install regular rules , If you do not need the remote login function , Don't write .

Last , Save overloads Nginx The configuration can be .

Pagoda method

The pagoda method is also very simple , After adding a website , Select reverse proxy ：

Reverse proxy

After adding any proxy , Editing ：

edit

Paste content ：

location /
{
	proxy_pass http://127.0.0.1:8008;
	proxy_set_header Host $host;
}
location ~ ^/(ws|terminal/.+)$
{
	proxy_pass http://127.0.0.1:8008;
	proxy_http_version 1.1;
	proxy_set_header Upgrade $http_upgrade;
	proxy_set_header Connection "Upgrade";
	proxy_set_header Host $host;
}

Modify the reverse proxy

among ：

location ~ ^/(ws|terminal/.+)$
{
	proxy_pass http://127.0.0.1:8008;
	proxy_http_version 1.1;
	proxy_set_header Upgrade $http_upgrade;
	proxy_set_header Connection "Upgrade";
	proxy_set_header Host $host;
}

For remote terminal function , need Nginx Install regular rules , If you do not need the remote login function , Don't write .

Browser access

This is the time , You can access it through the browser , If open CDN, There may be a caching mechanism , Remember to cache .

Browser access successful

Create probe

Now? , We can create the probe , The first is the initialization of the panel , Then create the probe , Finally, place the probe .

Initialization panel

Initialization panel , It's simple . After browser access panel , Click login ：

Click login

after , Will use Gitee/GitHub To verify ：

verification

After verification , Our initialization is complete .

Once the initialization is complete , Backstage

Add key

after , We add a key , Click on the Add host ：

Add servers

After adding , Get the key

This key is very important , That's what follows Agent secret key , Used to bind the server .

Insert the probe

after , We log in to the server we need to detect , Run... Above Build panels - Run script One click script in , That is to say ：

curl -L https://cdn.jsdelivr.net/gh/naiba/[email protected]/script/install.sh -o nezha.sh && chmod +x nezha.sh
CN=true sudo ./nezha.sh

Of course , If you have run this script before , You can run the script directly ：

If there is an installation script before

This is the time , We are not choosing Install the panel end 了 , But to choose 8( Installation monitoring Agent)：

Installation monitoring （ probe ）

i setup script

among ：

• Don't go ahead CDN Domain name of , That's what I mentioned above “「nezha.mintimate.cn： Probe connection domain name （ Not to be used CDN）」”

This is the time , We can go to the panel home page , See our server ：

Our servers

matters needing attention

Of course , You can also add more probes , But we need to pay attention ：

• Add host after , The key may not be displayed immediately , This is the reason for caching ; If you don't use it CDN, You can force the browser to refresh directly , If you use CDN, You can go to CDN The console is refreshed and preheated .
• The migration panel is simple , Data is stored in /opt/nezha In the folder , Package this folder when migrating data , Unzip to the new environment . Then execute the one click script installation .

END

Here we are , Our cloud probe panel has been installed . Many people are concerned about performance , In fact, whether it is a panel or a probe , The memory consumption of the server is extremely low .

among , Panel function , Can be found in 64M Running on the memory server , Probe words , Not to mention oh .

That's good
