Linux Service Management: Starting, Stopping, and Checking Status
Linux services are background-running programs with specific functionalities. Managing services is fundamental to system operations and requires administrative privileges (e.g., `$ sudo`). Core operations are implemented via the `systemctl` command: `systemctl status [service_name]` checks the status (e.g., `active (running)`); `start/stop/restart` are used to start, stop, and restart services respectively; `list-units --type=service` lists all services, and `is-active [service_name]` quickly determines the running status. For enabling/disabling services at boot, use `enable/disable`, and verify with `is-enabled`. When services fail, `journalctl -u [service_name]` checks logs (e.g., port conflicts, configuration errors). Mastering these commands fulfills most service management requirements.

This article introduces the basics of Linux service management, where mainstream distributions use the `systemctl` (systemd) tool to manage services. Key commands and their functions include: `start`/`stop` (start/stop), `restart` (restart), `reload` (reload configuration), `status` (check status), and `enable`/`disable` (enable/disable on boot), all requiring `root` or `sudo` privileges. Service names vary across distributions: for example, Apache is `httpd` in CentOS and `apache2` in Ubuntu; MariaDB (CentOS) or MySQL (Ubuntu) are the service names for database services. Common issues include: adding `sudo` for permission errors, using `status` or `journalctl` to troubleshoot startup failures, and searching for service names with `systemctl list-unit-files` if forgotten. Mastering core commands, service name differences, and troubleshooting methods enables proficient server service management.
Read MoreA Comprehensive Guide to Starting and Stopping Linux Services
This article introduces the core methods for managing Linux services. Services are background - running programs, and management is fundamental to system maintenance. Modern Linux uses the systemctl tool of systemd for management. The core operations include: starting a service with `sudo systemctl start <service name>`, stopping it with `stop`, restarting with `restart`, and checking the status with `status`; setting it to start automatically at boot with `enable` and disabling it with `disable`. The self - starting status can be viewed through `list - unit - files`. Practical operations include: reloading the configuration (without restarting) with `reload` and viewing logs with `journalctl -u <service name>`. Precautions: `sudo` privilege elevation is required, the service name must be accurate (e.g., Nginx is `nginx`), and ensure the service is installed before operation. `stop` will forcefully terminate the service and may lose data; `restart` or `reload` (safer) is preferred. Mastering these can meet basic operation and maintenance needs.
