我试图制作如下的系统服务:
[Unit]
Description=Syslog
[Service]
Type=simple
Environment="TESTEXTSERVICESFILES=/opt/test/extservices"
Environment="TESTCONFDATA=/storage/test/conf"
ExecStartPre=/bin/echo ${TESTEXTSERVICESFILES}/syslog/bin/nxlog $TESTCONFDATA
ExecStart=/opt/test/extservices/syslog/bin/nxlog -c ${TESTCONFDATA}/syslog/nxlog.conf
#ExecStart=/${TESTEXTSERVICESFILES}/syslog/bin/nxlog -c ${TESTCONFDATA}/syslog/nxlog.conf
[Install]
WantedBy=multi-user.target
运行' sudo systemctl daemon-reload; sudo systemctl start test-syslog; sudo systemctl status test-syslog ',我得到以下成功输出:
? test-syslog.service - TestSyslog
Loaded: loaded (/usr/lib/systemd/system/test-syslog.service; enabled; vendor preset: disabled)
