我想创建一个运行python脚本的服务。到目前为止,我的情况是:
[Unit]
Description=A test unit
[Service]
ExecStart=/usr/bin/python3 /home/telnet/projects/test.py
Restart=on-abort
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=test
.py
文件import os
import time
i = 0
log = str(os.path.dirname(os.path.abspath(__file__))) + \
'/logs/test_service_log.txt'
f = open(log, 'w')
def write():
global i, log
named_tuple = time.localtime()
string_time = time.strftime('%d/%m/%Y, %H:%M:%S', named_tuple)
f.write(str(i) + '\t' + string_time + '\thello' + '\tbye' + '\n')
i = i+1
while True:
write()
time.sleep(1)
执行py test.py
工作,并且f
文件会被字符串填充
但是,当从服务运行脚本时,我得到以下结果:
test.service - A test unit
Loaded: loaded (/etc/systemd/system/test.service; static; vendor preset: enab
Active: active (running) since Wed 2017-04-12 02:33:57 CEST; 4s ago
Main PID: 1546 (python3)
Tasks: 1 (limit: 512)
Memory: 3.1M
CPU: 113ms
CGroup: /system.slice/test.service
└─1546 /usr/bin/python3 /home/telnet/projects/test.py
但是f
文件是空的。上面什么也没写
你需要关闭文件 试试这个:
