Node.js 使用systemd在ubuntu 16.04启动时启动脚本
我有一个简单的脚本“start.sh”,我想让它在每次ubuntu 16.04重新启动时自动启动 我跟随这篇文章: 制作一个简单的脚本: 我把它放在这里了Node.js 使用systemd在ubuntu 16.04启动时启动脚本,node.js,ubuntu,systemd,forever,ubuntu-16.04,Node.js,Ubuntu,Systemd,Forever,Ubuntu 16.04,我有一个简单的脚本“start.sh”,我想让它在每次ubuntu 16.04重新启动时自动启动 我跟随这篇文章: 制作一个简单的脚本: 我把它放在这里了 /lib/systemd/system/test_run_at_boot.service 我把它链接起来了 /etc/systemd/system/multi-user.target.wants/test_run_at_boot.service -> /lib/systemd/system/test_run_at_boot.servi

我把它链接起来了
/etc/systemd/system/multi-user.target.wants/test_run_at_boot.service -> /lib/systemd/system/test_run_at_boot.service
每次我重新启动我的机器,它都不会启动
我还尝试附加实际的命令来测试\u boot.service上的\u run\u,但仍然不起作用

在syslog中,我得到了这个<代码>/usr/bin/env:'node':没有这样的文件或目录,这会导致脚本在启动时失败

我关注这个帖子
我做了一些改变
它可以在重新启动后启动服务,但在1-2分钟后,服务就会消失。见下文

在systemd下使用forever有点像使用forever来永远运行 如果没有“永远”,systemd配置将变得更简单
[Unit]
Description=test_run_at_boot
[Service]
ExecStart=/usr/bin/nodejs /home/ubuntu/misc/service/test_run_at_boot/test_run_at_boot.js
Type=oneshot
#Restart=on-failure
[Install]
WantedBy=multi-user.target
您正在使用的测试脚本是a,因为该脚本将退出,否则systemd将报告服务失败。一旦要管理长期运行的服务,您可以删除Type=oneshot
,并使用Restart=on failure
保持服务正常运行,就像永远一样
来自流程的stderr
和stdout
被发送到systemd日志。在Ubuntu上,这将转到syslog
如果您真的需要forever的功能,那么systemd需要更多的设置。这个您将需要设置一个
--pidFile
并具有一个匹配的系统D。您是否已使用systemctl enable
启用该服务?通常情况下,ubuntua上的nodejs
,当您拥有系统时,您不需要永远使用它,这更是一个问题
