ExecStart 在 Golang webapp 的 systemd 服务中失败
ExecStart fails in systemd service for Golang webapp
我是 golang 的新手,正在尝试在我的服务器上托管一个简单的网站。
我在 Ubuntu 18.04
我的域名根目录在/var/www/vhosts/mydomain.com/mydomain.com
我有一个 main.go
文件,它在浏览器中呈现一个简单的 Hello World。
当我从这个目录 go run main.go
时,网页工作正常。
现在我正在尝试创建一项服务,以便在我关闭 shell
时保持网页可用。
为此,我在 /etc/systemd/system
创建了一个名为 golangweb.service
的新 service
。
该文件的内容是:
[Unit]
Description = Go Server
[Service]
ExecStart=/var/www/vhosts/mydomain.com/mydomain.com
Type=simple
Restart=always
RestartSec=5
[Install]
WantedBy=multi-user.target
保存文件后,我按顺序插入以下命令:
sudo systemctl daemon-reload
sudo systemctl enable golangweb.service
sudo systemctl start golangweb.service
sudo systemctl status golangweb.service
当我尝试获取状态时出现以下错误(我修正了那里的一些数据):
golangweb.service - Go Server

Active: activating (auto-restart) (Result: exit-code) since Fri xx-xx-xx 23:43:52

有人知道为什么会这样吗?
ExecStart
的第一个参数需要是一个可执行文件。看起来你已经将它设置为一个目录。如果您尝试在 shell 提示符下键入 /var/www/vhosts/mydomain.com/mydomain.com
,您会看到类似的行为:您不能 运行 目录。
您可以设置:
WorkingDirectory=/var/www/vhosts/mydomain.com/mydomain.com
ExecStart=/usr/bin/go run main.go
或者,您可以编译代码 (go build
),然后将 ExecStart
设置为已编译二进制文件的完整路径:
ExecStart=/var/www/vhosts/mydomain.com/mydomain.com/compiledprogramname
