在Linux中,可以使用Ruby腳本來管理系統服務
首先,確保已經安裝了Ruby和相關的gem包。在大多數Linux發行版中,Ruby已經預裝。你可以通過運行ruby -v
來檢查Ruby是否已經安裝。
安裝sys-proctable
gem包,它提供了與系統進程表交互的功能。在終端中運行以下命令:
sudo gem install sys-proctable
manage_service.rb
的Ruby腳本,并添加以下內容:require 'sys/proctable'
def service_running?(service_name)
Sys::ProcTable.ps.any? { |process| process.comm == service_name }
end
def start_service(service_name)
system("systemctl start #{service_name}")
end
def stop_service(service_name)
system("systemctl stop #{service_name}")
end
def restart_service(service_name)
system("systemctl restart #{service_name}")
end
def manage_service(service_name, action)
case action
when 'start'
if service_running?(service_name)
puts "#{service_name} is already running."
else
start_service(service_name)
puts "#{service_name} has been started."
end
when 'stop'
if service_running?(service_name)
stop_service(service_name)
puts "#{service_name} has been stopped."
else
puts "#{service_name} is not running."
end
when 'restart'
restart_service(service_name)
puts "#{service_name} has been restarted."
else
puts "Invalid action. Please use 'start', 'stop', or 'restart'."
end
end
if ARGV.length != 2
puts "Usage: ruby manage_service.rb<service_name><action>"
else
service_name = ARGV[0]
action = ARGV[1]
manage_service(service_name, action)
end
<service_name>
替換為要管理的服務名稱,將<action>
替換為要執行的操作(start、stop或restart):ruby manage_service.rb<service_name><action>
這個腳本會根據提供的參數來啟動、停止或重啟指定的系統服務。請注意,你可能需要使用sudo
來運行此腳本,以便具有足夠的權限來管理系統服務。
