# Nginx File Upload Size Limit Exceeded Incident
---

This incident type occurs when the Nginx server encounters a file upload request that exceeds the size limit configured for the server. As a result, the server may fail to upload the file, return an error message to the user, or in some cases, crash. This type of incident can impact file sharing and other operations that depend on file uploads to the server.

### Parameters
```shell
export FILE_PATH="PLACEHOLDER"

export NEW_MAX_SIZE="PLACEHOLDER"

export NGINX_CONF_PATH="PLACEHOLDER"
```

## Debug

### Check the Nginx version
```shell
nginx -v
```

### Check the Nginx configuration file for the upload size limit
```shell
cat /etc/nginx/nginx.conf | grep client_max_body_size
```

### Check the Nginx error logs for any relevant error messages
```shell
tail -f /var/log/nginx/error.log
```

### Check the size of file to be uploaded
```shell
ls -lh ${FILE_PATH}
```

### Check the server's disk usage and available space
```shell
df -h
```

### Check the server's memory usage
```shell
free -m
```

### Check the server's CPU usage
```shell
top
```

## Repair

### Increase the maximum file upload size limit of Nginx server to accommodate larger files.
```shell
bash

#!/bin/bash



# Define the new maximum file upload size limit

NEW_MAX_SIZE=${NEW_MAX_SIZE}



# Define the path to the Nginx configuration file

NGINX_CONF=${NGINX_CONF_PATH}



# Update the Nginx configuration file to set the new maximum file size limit

sed -i 's/client_max_body_size [0-9]*m;/client_max_body_size ${NEW_MAX_SIZE}m;/g' $NGINX_CONF



# Restart the Nginx server to apply the changes

sudo systemctl restart nginx
