Proxy Configuration

To ensure that your HAP system is not directly exposing service ports to the internet, we strongly recommend further configuring Nginx proxy after deploying the system. This can greatly enhance the security of the system and meet the needs of users requiring certificates, who can refer to relevant documentation for configuration. Additionally, Nginx proxy can also provide load balancing and reverse proxy, improving the system's availability and stability.

Download the Nginx installation package.

Internet Access Available

wget https://pdpublic.mingdao.com/private-deployment/offline/common/Nginx1.22.0-glibc2.17.tar.gz

# Download link for the Nginx installation package. Upload it to the deployment server after downloading.
https://pdpublic.mingdao.com/private-deployment/offline/common/Nginx1.22.0-glibc2.17.tar.gz

Unpack the Nginx installation package to the installation directory.
```
tar -zxvf Nginx1.22.0-glibc2.17.tar.gz -C /usr/local/
```

Create storage directories for configuration and logs.

mkdir -p /usr/local/Nginx/conf/conf.d /data/logs/weblogs/

Write the main Nginx configuration file.

Configure the host proxy file.(Put the following configuration files in the directory /usr/local/Nginx/conf/conf.d/)

HTTP Configuration File

HTTPS Configuration File
Start Nginx.

Check the format of the Nginx configuration file.
```
/usr/local/Nginx/sbin/Nginx -t
```
Start Nginx.
```
/usr/local/Nginx/sbin/Nginx
```

Set up auto-start on boot.

echo "/usr/local/Nginx/sbin/Nginx" >> /etc/rc.local
chmod +x /etc/rc.d/rc.local

Scheduled rotation of Nginx logs

Create directories for configuration files and old logs.

mkdir -p /usr/local/logrotate-config
mkdir -p /data/logs/weblogs/oldlogs

Create a configuration file.

cat > /usr/local/logrotate-config/Nginx <<EOF
/data/logs/weblogs/*.log {
create 0664 nobody root
daily
dateext
dateformat -%Y-%m-%d

postrotate
    /bin/kill -USR1 \`cat /usr/local/Nginx/Nginx.pid 2>/dev/null\` 2>/dev/null || true
endscript
}
EOF

Check the configuration file.
```
logrotate -d -f /usr/local/logrotate-config/Nginx
```
- Pay attention to debug outputs; further action is needed if errors are encountered.

Execute crontab -e and add the following scheduled tasks to the configuration.

# Use Logrotate Cut Nginx Logs
