在Linux中,可以使用Ruby脚本来管理系统服务
首先,确保已经安装了Ruby和相关的gem包。在大多数Linux发行版中,Ruby已经预装。你可以通过运行ruby -v
来检查Ruby是否已经安装。
安装sys-proctable
gem包,它提供了与系统进程表交互的功能。在终端中运行以下命令:
sudo gem install sys-proctable
manage_service.rb
的Ruby脚本,并添加以下内容: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>
替换为要管理的服务名称,将<action>
替换为要执行的操作(start、stop或restart):ruby manage_service.rb<service_name><action>
这个脚本会根据提供的参数来启动、停止或重启指定的系统服务。请注意,你可能需要使用sudo
来运行此脚本,以便具有足够的权限来管理系统服务。
