python systemd_通过systemd运行Python脚本

我对编写systemd服务脚本还是个新手。我是按照这个useful page写我自己的。它的失败如下。在

在Centos 7机器中prodKPI.service中的/etc/systemd/system/内容如下[Unit]

Description=prodKPI: Aggregation logic to compute device availability

[Service]

Type=simple

PermissionsStartOnly=true

User=deployuser

ExecStart = /usr/bin/python /tmp/app1/folder1/file1.py; /usr/bin/python /tmp/folder2/file2.py

Restart=always

[Install]

WantedBy=default.target

创建文件后我遵循的步骤是

^{pr2}$

做了reboot和# systemctl status prodKPI.service

● prodKPI.service - prodKPI: Aggregation logic to compute device availability

Loaded: loaded (/etc/systemd/system/prodKPI.service; enabled; vendor preset: disabled)

这帮不了什么忙journalctl -xe

下面的错误行表示某种权限问题？服务单元是否应该以不同的用户(或)访问级别运行？我将这两个python文件都改为可执行文件Jul 21 19:20:41 device-1 python[1190]: /usr/bin/python: can't open file '/tmp/app1/folder1/file1.py;': [Errno 2] No such file or directory
