如何将Systemd服务的输出重定向到文件 [英] How to redirect output of systemd service to a file
问题描述
我正在尝试将systemd
服务的输出重定向到文件,但是它似乎不起作用:
I am trying to redirect output of a systemd
service to a file but it doesn't seem to work:
[Unit]
Description=customprocess
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/bin/binary1 agent -config-dir /etc/sample.d/server
StandardOutput=/var/log1.log
StandardError=/var/log2.log
Restart=always
[Install]
WantedBy=multi-user.target
请更正我的方法.
推荐答案
我认为还有一种更优雅的解决方法:将stdout/stderr发送给具有标识符的syslog,并指示syslog管理器按程序拆分其输出名称.
I think there's a more elegant way to solve the problem: send the stdout/stderr to syslog with an identifier and instruct your syslog manager to split its output by program name.
在systemd服务单元文件中使用以下属性:
Use the following properties in your systemd service unit file:
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=<your program identifier> # without any quote
然后,假设您的发行版正在使用rsyslog管理syslog,请在/etc/rsyslog.d/<new_file>.conf
中创建一个文件,其内容如下:
Then, assuming your distribution is using rsyslog to manage syslogs, create a file in /etc/rsyslog.d/<new_file>.conf
with the following content:
if $programname == '<your program identifier>' then /path/to/log/file.log
& stop
现在使日志文件可通过syslog写入:
Now make the log file writable by syslog:
# ls -alth /var/log/syslog
-rw-r----- 1 syslog adm 439K Mar 5 19:35 /var/log/syslog
# chown syslog:adm /path/to/log/file.log
重新启动rsyslog(sudo systemctl restart rsyslog
)并享受!您的程序stdout/stderr仍可通过journalctl(sudo journalctl -u <your program identifier>
)获得,但它们也将在您选择的文件中提供.
Restart rsyslog (sudo systemctl restart rsyslog
) and enjoy! Your program stdout/stderr will still be available through journalctl (sudo journalctl -u <your program identifier>
) but they will also be available in your file of choice.
