How to Set up a Syslog Server in CentOS 8
- Syslog is useful for tracking information in network equipment, such as servers, firewalls, and routers.
- In Syslog, in the event of a crash in the remote server, people do not have to worry about losing data because they are available on Syslog.
- In the new server, Syslog has to be managed by Rsyslog, and this aspect makes it easy to work.
- Syslog is a major server sd, and all the servers are internally controlled and used by Rsyslog even after being remote in Syslog.
- Windows-based servers do not support Syslog directly but are supported by third parties.
To install Rsyslog, use the following command:
If the service is not running correctly or if Rsyslog is not, use the following command:
After this, we will start the service by giving the command:
Now, to make Rsyslog a centralized service, use the command:
In this step, “module(load=”imudp”) # requires setting up Rsyslog server in UDP by port 514, so use this command:
In “module(load=”imtcp”) # use the following command for accessing TCP Rsyslog:
After this, to restart the service, use the command provided:
The next form is the log server to act as a centralized log server and record in Syslog as soon as it starts. To confirm this, use the command:
Also, if it doesn’t have NetStart installed, then install it through this command:
Now, if the SEmanage command is not activated, you have to provide this command:
dnf install policycoreutils-python-utils
This will activate SELinux. To allow Rsyslog traffic when SELinux is enabled, use the following command:
semanage port -a -t syslogd_port_t -p tcp 514 (in TCP)
If the server has a firewall enabled, then use these commands for the firewall port permission:
"firewall-cmd --permanent --add-port=514/tcp (in TCP)
Also, you can use this command:
