在一个Amazon S3 Linux实例中,我有两个名为start_my_app和stop_my_app的脚本,它们永远地启动和停止(反过来运行我的Node.js应用程序)。我使用这些脚本手动启动和停止我的Node.js应用程序。到目前为止一切顺利。

我的问题是:我还想设置它,以便在系统启动时运行start_my_app。我知道我需要在init中添加一个文件。d和我知道如何符号链接到rc内的适当目录。d,但是我不知道我放在init。d中的文件里到底需要什么。我认为它应该只有一行,比如start_my_app,但这对我来说并不管用。

使用Python 3微服务或shell;使用Ubuntu Server 18.04 (Bionic Beaver)或Ubuntu 19.10 (Eoan Ermine)或Ubuntu 18.10 (Cosmic Cuttlefish)我总是喜欢这些步骤,而且它也总是有效:

Creating a microservice called p example "brain_microservice1.service" in my case: $ nano /lib/systemd/system/brain_microservice1.service Inside this new service that you are in: [Unit] Description=brain_microservice_1 After=multi-user.target [Service] Type=simple ExecStart=/usr/bin/python3.7 /root/scriptsPython/RUN_SERVICES/microservices /microservice_1.py -k start -DFOREGROUND ExecStop=/usr/bin/python3.7 /root/scriptsPython/RUN_SERVICES/microservices/microservice_1.py -k graceful-stop ExecReload=/usr/bin/python3.7 /root/scriptsPython/RUN_SERVICES/microservices/microservice_1.py -k graceful PrivateTmp=true LimitNOFILE=infinity KillMode=mixed Restart=on-failure RestartSec=5s [Install] WantedBy=multi-user.target Give the permissions: $ chmod -X /lib/systemd/system/brain_microservice* $ chmod -R 775 /lib/systemd/system/brain_microservice* Give the execution permission then: $ systemctl daemon-reload Enable then, this will make then always start on startup $ systemctl enable brain_microservice1.service Then you can test it; $ sudo reboot now Finish = SUCCESS!!

这可以用相同的主体脚本来运行shell, react…数据库启动脚本…任何类型的OS代码…希望这能帮助你…

对某些人来说,这是可行的:

您可以简单地添加以下命令到系统→首选项→启动应用程序:

bash /full/path/to/your/script.sh

你可以这样做:

chmod +x PATH_TO_YOUR_SCRIPT/start_my_app 

然后使用下面的命令

update-rc.d start_my_app defaults 100

请参阅有关Cyberciti的本页。

使用sudo输入cron:

Sudo crontab -e

添加一个在启动时运行的命令,在这种情况下是一个脚本:

@reboot sh /home/user/test.sh

拯救策略:

按ESC然后:x保存并退出,或者按ESC然后ZZ(也就是shift+ ZZ)

测试测试:

运行不带cron的测试脚本,以确保它实际工作。 确保您将命令保存在cron中,使用sudo crontab -e 重启服务器以确认一切正常sudo @reboot

在卢本图,我不得不处理相反的情况。Skype启动后开始运行,我发现在~/。配置/自动启动/ skypeforlinux.desktop文件文件内容如下:

[Desktop Entry]
Name=Skype for Linux
Comment=Skype Internet Telephony
Exec=/usr/bin/skypeforlinux
Icon=skypeforlinux
Terminal=false
Type=Application
StartupNotify=false
X-GNOME-Autostart-enabled=true

删除这个文件对我有帮助。
