[英]Fedora 20 how to run script at the end of startup
I am using Fedora 20 . 我正在使用Fedora 20 。 I have a two lines bash script needs to be run at the end of the startup.
我需要在启动结束时运行两行bash脚本。 I want it to be run automatically each time when machine is startup.
我想让它在每次机器启动时自动运行 。 How can I do this?
我怎样才能做到这一点?
I tried "sudo crontab -e" to insert my executable script but it always gave me error teling me the the time is not right and cannot modify the file. 我试过“sudo crontab -e”来插入我的可执行脚本,但它总是给我错误,告诉我时间不对,无法修改文件。
You can create a Systemd unit file in /usr/lib/systemd/system/<service_name>.service . 您可以在/usr/lib/systemd/system/<service_name>.service中创建Systemd单元文件。 Here is a template:
这是一个模板:
[Unit]
Description=<description_string>
[Service]
WorkingDirectory=<working_directory>
Type=forking
ExecStart=/bin/bash <absolute_path_to_script>
KillMode=process
[Install]
WantedBy=multi-user.target
Replace anything in the angle brackets with your specific information. 用您的特定信息替换尖括号中的任何内容。 The 'WantedBy=multi-user.target' is the magic that tells Systemd to run your script on each start.
'WantedBy = multi-user.target'是告诉Systemd在每次启动时运行脚本的神奇之处。
On the command line, tell Systemd to enable your service: 在命令行上,告诉Systemd启用您的服务:
systemctl enable <service_name>.service
The next time you reboot your script should be run. 下次重新启动脚本时应该运行。 Logs will be written to /var/log/messages.
日志将写入/ var / log / messages。
Fedora has some basic documentation on unit files: Systemd unit files Fedora有一些关于单元文件的基本文档: Systemd单元文件
You can append /etc/rc.local
it runs just after the system starts up. 您可以在系统启动后附加
/etc/rc.local
附加它。
You may have to create it if doesn't exist: 如果不存在,您可能必须创建它:
Charlie's answer is better but you can still use Tiago's answer. 查理的答案更好,但你仍然可以使用蒂亚戈的答案。
Just don't forget if you want to use /etc/rc.local
way, grant execution permission to this file after editing: 如果您想使用
/etc/rc.local
方式,请不要忘记,在编辑后授予此文件的执行权限:
chmod +x /etc/rc.local
