= Modifying existing Systemd services
|
||
|
|
|
||
|
|
This example shows how to modify an existing service. The files for service modification are stored in a directory within `/etc/systemd/system`. This directory is named after the service. For example, this procedure modifies the `httpd` service.
|
||
|
|
|
||
|
|
.Prerequisites
|
||
|
|
|
||
|
|
* You are logged in as a user with administrator-level permissions.
|
||
|
|
|
||
|
|
* You have a configured `httpd` server running through Systemd.
|
||
|
|
|
||
|
|
.Procedure
|
||
|
|
|
||
|
|
. Create a directory for the service modification in the following format: `[SERVICE NAME].service.d`. For example, the directory for the `httpd.service` modification is `httpd.service.d`:
|
||
|
|
+
|
||
|
|
----
|
||
|
|
$ sudo mkdir /etc/systemd/system/httpd.service.d/
|
||
|
|
----
|
||
|
|
|
||
|
|
. Create a configuration file within this directory:
|
||
|
|
+
|
||
|
|
----
|
||
|
|
$ sudo vi /etc/systemd/system/httpd.service.d/custom.conf
|
||
|
|
----
|
||
|
|
|
||
|
|
. Add your custom configuration. For example:
|
||
|
|
+
|
||
|
|
----
|
||
|
|
[Service]
|
||
|
|
Restart=always
|
||
|
|
RestartSec=30
|
||
|
|
----
|
||
|
|
|
||
|
|
. Save the file.
|
||
|
|
|
||
|
|
. Restart the `httpd` service:
|
||
|
|
+
|
||
|
|
----
|
||
|
|
$ sudo systemctl restart httpd
|
||
|
|
----
|
||
|
|
|
||
|
