# API Reference: Rsyslog Centralization with TLS
|
|
|
|
## Rsyslog Server Configuration Directives
|
|
|
|
### TLS Module Loading
|
|
```
|
|
module(load="imtcp"
|
|
StreamDriver.Name="gtls"
|
|
StreamDriver.Mode="1"
|
|
StreamDriver.Authmode="x509/name"
|
|
PermittedPeer=["client1.local","client2.local"])
|
|
```
|
|
|
|
### Global TLS Settings
|
|
```
|
|
global(
|
|
DefaultNetstreamDriver="gtls"
|
|
DefaultNetstreamDriverCAFile="/path/to/ca.pem"
|
|
DefaultNetstreamDriverCertFile="/path/to/cert.pem"
|
|
DefaultNetstreamDriverKeyFile="/path/to/key.pem")
|
|
```
|
|
|
|
### Template Syntax
|
|
```
|
|
template(name="PerHostDir" type="string"
|
|
string="/var/log/remote/%HOSTNAME%/%PROGRAMNAME%.log")
|
|
template(name="JSONFormat" type="string"
|
|
string='{"host":"%HOSTNAME%","msg":"%msg:::json%"}\n')
|
|
```
|
|
|
|
## Rsyslog Client Forwarding
|
|
```
|
|
action(type="omfwd" target="<server>" port="6514" protocol="tcp"
|
|
StreamDriver="gtls" StreamDriverMode="1"
|
|
StreamDriverAuthMode="x509/name"
|
|
queue.type="LinkedList" queue.filename="fwdRule1"
|
|
queue.maxdiskspace="1g" queue.saveonshutdown="on"
|
|
action.resumeRetryCount="-1")
|
|
```
|
|
|
|
## Jinja2 Template Engine
|
|
```python
|
|
from jinja2 import Template
|
|
tmpl = Template("target={{ server_ip }} port={{ port }}")
|
|
output = tmpl.render(server_ip="10.0.0.1", port=6514)
|
|
```
|
|
|
|
## Paramiko SSH Deployment
|
|
```python
|
|
import paramiko
|
|
client = paramiko.SSHClient()
|
|
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
|
|
client.connect(hostname=host, username=user, key_filename=key)
|
|
sftp = client.open_sftp()
|
|
sftp.file(remote_path, "w").write(content)
|
|
client.exec_command("systemctl restart rsyslog")
|
|
client.close()
|
|
```
|
|
|
|
## OpenSSL Certificate Generation
|
|
```bash
|
|
openssl req -x509 -newkey rsa:4096 -keyout ca-key.pem -out ca.pem -days 3650 -nodes
|
|
openssl req -newkey rsa:2048 -keyout server-key.pem -out server.csr -nodes
|
|
openssl x509 -req -in server.csr -CA ca.pem -CAkey ca-key.pem -out server-cert.pem
|
|
```
