Create a remote log source (Apache HTTP Server For CentOS 6)
To obtain Log Relay and to configure your account for remote log collection, you must have the following AMP permissions added to your account:
- Write Virtual Machine
- Delete Log Management
- Read Log Endpoints
- Read Log Relays
- Write Log Relays
- Delete Log Relays
You can use this document to add a remote log collector to an Apache HTTP Server remote device (log source).
For remote log collection, you must have Log Relay added to your account.
- To learn how to add Log Relay to your account, see Obtain Log Relay for Remote Log Collection.
Create a remote log source
- In the Armor Management Portal (AMP), in the left-side navigation, click Security.
- Click Log & Data Management.
- Click External Sources.
- Click the plus ( + ) sign.
- If you do not have any log sources already created, then click Add a New Log Source.
- Complete the missing fields:
- In Endpoint, select the available Armor Endpoint.
- In Log Source Type, select Apache HTTP Server.
In Hostname, enter the system hostname that matches the system for syslog collection. For example, in Mar 10 08:52:55 node-77 systemd: < redacted >, the hostname would be node-77.
- The hostname is case-sensitive and must match the same letter casing as the logs that are sent into this log source.
- In Protocol, select TLS Syslog.
- Click Save Log Source.
Before you begin, ensure that the following pages are installed:
- yum install -y rsyslog-gnutls
- Create a directory to hold Armor pem file:
- mkdir -pv /etc/rsyslog.d/keys/ca.d
- Change to the newly created directory:
- cd /etc/rsyslog.d/keys/ca.d
- Download Armor PEM files:
- Place the following two lines in main http.conf or vhost config (will be needed for each vhost):
- LogFormat "%h %A %l %u %t \"%r\" %>s %p %b" ArmorCustom
- CustomLog "|/usr/bin/logger -t httpd -p local6.info" ArmorCustom
- Create a file called /etc/rsyslog.d/55-armor.conf with the following template:
Replace target-name:port with the name of the configured endpoint and port.
Ensure that rsyslog configuration has no syntax errors:
Ensure that httpd configuration has no syntax errors:
service httpd reload
service rsyslog restart
If enforced, RHEL/CentOS - SELinux will block rsyslog from using a remote port. To troubleshoot:
Install SELinux troubleshooting tool:
yum install -y setroubleshoot-server
Check to see if rsyslog is being blocked from using remote port
sealert -a /var/log/audit/audit.log
Follow recommendations to allow: Example:
grep 72733A6D61696E20513A526567 /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.pp
