**The service in the monitored server is called Agent. This document will describe how to install the Agent on the monitored server and connect it with Dashboard**
|
||
<br/>
|
||
## Install Agent using one-click script
|
||
Nezha Monitoring now supports one-click installation of the Agent on Windows and Linux. Follow the steps in this document and you can easily deploy it on your server
|
||
<br/>
|
||
### Preparation
|
||
First of all, you need to set up the communication domain name in the settings page of the admin panel, this domain name can not connect to the CDN, here is the sample communication domain name "data.example.com" mentioned earlier for demonstration
|
||
Enter the administration panel, go to the "Settings" page, in the item "CDN Bypassed Domain/IP
|
||
", fill in the communication domain name, and then click "Save"
|
||
<br/>
|
||
### One-click installation on Linux (Ubuntu, Debian, CentOS)
|
||
* First add a server in the admin panel
|
||
* Click on the green Linux icon button next to the newly added server and copy the one-click installation command
|
||
* Run the copied one-click installation command on the monitored server, wait for the installation to complete, and then return to the Dashboard home page to see if the server is online.
|
||
<br/>
|
||
### One-click installation on Windows
|
||
* First add a server in the admin panel
|
||
* Click on the green Linux icon button next to the newly added server and copy the one-click installation command
|
||
* Login to Windows Server, open PowerShell, and run the copied installation command in PowerShell
|
||
* If you encounter the prompt "Implement Policy Change" please select Y
|
||
* Wait for the installation to complete and return to the Dashboard home page to see if the server is online
|
||
<br/>
|
||
<br/>
|
||
## Other ways to install Agent
|
||
<br/>
|
||
|
||
### Installing Agent on Linux (Ubuntu, Debian, CentOS)
|
||
* First add a server in the admin panel
|
||
* In the monitored server, run the script:
|
||
```bash
|
||
curl -L https://raw.githubusercontent.com/naiba/nezha/master/script/install_en.sh -o nezha.sh && chmod +x nezha.sh && sudo ./nezha.sh
|
||
```
|
||
* Select “Install_agent”
|
||
|
||
* Input the communication domain name, e.g. "data.example.com"
|
||
|
||
* Input RPC port, default is 5555
|
||
|
||
* Input the Agent Secret, which is generated when adding a server in the administration panel and can be found in the " Servers " page of the administration panel
|
||
|
||
* Wait for the installation to complete and return to the Dashboard home page to see if the server is online
|
||

### Installing Agent on Windows
|
||
- Please refer to the community article:

|
||
::: warning
|
||
If you are prompted with "macOS cannot verify this app" during installation, please go to system settings to allow the app to run.
|
||
:::
|
||
|
||
+ First add a server in the admin panel
|
||
+ Go to the [Release](https://github.com/naiba/nezha/releases) page to download the Agent binary and choose whether to download the darwin amd64 or arm64 Agent depending on the CPU architecture
|
||
For example, download the amd64 version for Intel CPU and the arm64 version for Apple Silicon. After downloading, extract the Agent binary file, e.g. to the Download folder
|
||
+ Create a new file named `nezha_agent.plist` and save it, edit the contents of the file:
|
||
```xml
|
||
<?xml version="1.0" encoding="UTF-8"?>
|
||
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
|
||
<plist version="1.0">
|
||
<dict>
|
||
<key>KeepAlive</key>
|
||
<true/>
|
||
<key>Label</key>
|
||
<string>nezha_agent</string>
|
||
<key>Program</key>
|
||
<string>Change the path of the Agent binary here, e.g. /Users/123/Downloads/nezha-agent</string>
|
||
<key>ProgramArguments</key>
|
||
<array>
|
||
<string>Change the path of the Agent binary here, e.g. /Users/123/Downloads/nezha-agent</string>
|
||
<string>--password</string>
|
||
<string>Communication Secret, eg: 529664783eeb23cc25</string>
|
||
<string>--server</string>
|
||
<string>Communication URL and RPC port, eg:data.example.com:5555</string>
|
||
</array>
|
||
<key>RunAtLoad</key>
|
||
<true/>
|
||
</dict>
|
||
</plist>
|
||
```
|
||
+ Use the following command in Terminal to load the plist file into launchd
|
||
**Be sure to change the file path**
|
||
```shell
|
||
launchctl load /Users/123/Desktop/nezha_agent.plist
|
||
```
|
||
+ Start Service
|
||
```shell
|
||
launchctl start nezha_agent
|
||
```
|
||
+ Check if the service is running
|
||
```shell
|
||
launchctl list | grep nezha_agent
|
||
```
|
||
+ Stop service and remove
|
||
```shell
|
||
launchctl stop nezha_agent
|
||
```
|
||
```shell
|
||
launchctl remove nezha_agent
|
||
```

|

|
||
**How to make the new version of OpenWRT self-boot? By @艾斯德斯**
|
||
* First download the corresponding binary from the release, unzip the zip package and place it in `/root`
|
||
* Then run `chmod +x /root/nezha-agent` to give it execute access, create file `/etc/init.d/nezha-service`：
|
||
|
||
```shell
|
||
#!/bin/sh /etc/rc.common
|
||
|
||
START=99
|
||
USE_PROCD=1
|
||
|
||
start_service() {
|
||
procd_open_instance
|
||
procd_set_param command /root/nezha-agent -s data.example.com:5555 -p secreat -d
|
||
procd_set_param respawn
|
||
procd_close_instance
|
||
}
|
||
|
||
stop_service() {
|
||
killall nezha-agent
|
||
}
|
||
|
||
restart() {
|
||
stop
|
||
sleep 2
|
||
start
|
||
}
|
||
```
|
||
|
||
* Give it permission to execute: `chmod +x /etc/init.d/nezha-service`
|
||
* Start the service `/etc/init.d/nezha-service enable && /etc/init.d/nezha-service start`

## FAQ
|
||
### Is there a Docker image for Agent?
|
||
**There is currently no Docker image for Agent.**
|
||
The Agent is designed to be the opposite of the Dashboard, in that the Dashboard is designed to work without affecting the server as much as possible, while the Agent needs to execute monitoring services and run commands in the server.
|
||
Putting the Agent in a container does continue to execute monitoring services, but features such as WebShell do not work, so we do not provide Docker image of the Agent. |
