我有这个SystemD服务的问题：
[单位]说明= RTC客户端服务后= rds.service需要= rds.service
[Service] User=USER Group=GROUP PermissionsStartOnly=true RuntimeDirectory=rtc_client RuntimeDirectoryMode=0770 WorkingDirectory=/usr/lib/systemd/scripts/ Type=forking ExecStartPre=/bin/mkdir -p /var/run/rtc_client ExecStartPre=/bin/chown -R USER:GROUP /var/run/rtc_client ExecStart=/bin/bash rtc_client.sh start ExecStop=/bin/bash rtc_client.sh stop Restart=no PIDFile=/var/run/rtc_client/rtc_client.pid TimeoutStartSec=0 TimeoutStopSec=30 [Install] WantedBy=multi-user.target 机器每天早上启动。 该服务执行ExecStart，但突然停止，因为它试图杀死进程PID：
rtc_client.service - RTC Client Services Loaded: loaded (/usr/lib/systemd/system/rtc_client.service; enabled) Active: failed (Result: exit-code) since Thu 2016-06-23 06:25:46 CEST; 3h 33min ago Process: 2754 **ExecStop**=/bin/bash rtc_client.sh stop (code=exited, status=0/SUCCESS) Process: 1819 **ExecStart**=/bin/bash rtc_client.sh start (code=exited, status=0/SUCCESS) Process: 1815 ExecStartPre=/bin/chown -R USER:USER /var/run/rtc_client (code=exited, status=0/SUCCESS) Process: 1813 ExecStartPre=/bin/mkdir -p /var/run/rtc_client (code=exited, status=0/SUCCESS) Main PID: 1949 (code=exited, status=1/FAILURE) CGroup: /system.slice/rtc_client.service Jun 23 06:25:46 zprds60 bash[2754]: Database Connection Information Jun 23 06:25:46 zprds60 bash[2754]: Database server = DB2/LINUXZ64 10.5.5 Jun 23 06:25:46 zprds60 bash[2754]: SQL authorization ID = USER Jun 23 06:25:46 zprds60 bash[2754]: Local database alias = DBALIAS Jun 23 06:25:46 zprds60 bash[2754]: /home/pers5i/.bash_profile: line 97: unalias: vi: not found Jun 23 06:25:46 zprds60 bash[2754]: USER IS: root Jun 23 06:25:46 zprds60 bash[2754]: PID IS: 1949 **Jun 23 06:25:46 zprds60 bash[2754]: rtc_client.sh: line 34: kill: (1949) - No such process** Jun 23 06:25:46 zprds60 bash[2754]: logout Jun 23 06:25:46 zprds60 systemd[1]: Unit rtc_client.service entered failed state.
以下是rtc_client.service启动的脚本：
#!/bin/bash RTCENGINEID=$HOSTNAME'_engine' RTCUSER='RTCUSER' RTCPW='RTCPWD' RTCSERVER='server.example.com' RTCSERVERPORT='????' RTCREPOSITORY=https://$RTCSERVER:$RTCSERVERPORT/ccm WORKDIR='/opt/ibm/buildsystemtoolkit/buildsystem/buildengine/eclipse' JAVACMD=/opt/ibm/java-s390x-71/jre/bin/java ARGS="-cp ./plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar org.eclipse.equinox.launcher.Main -application com.ibm.team.build.engine.jazzBuildEngine -repository $RTCREPOSITORY -engineId $RTCENGINEID -userId $RTCUSER -pass $RTCPW" RTCJAR=org.eclipse.equinox.launcher PIDFILE='/var/run/rtc_client/rtc_client.pid' DEBUGLOG='/tmp/rtc_debug.log' . /home/USER/.bash_profile start() { cd $WORKDIR nohup $JAVACMD $ARGS > $DEBUGLOG & sleep 5 pgrep -f $RTCJAR > $PIDFILE echo "USER IS: " $(whoami) | tee -a $DEBUGLOG echo "PID IS: " $(cat $PIDFILE) | tee -a $DEBUGLOG } stop() { echo "USER IS: " $(whoami) | tee -a $DEBUGLOG echo "PID IS: " $(cat $PIDFILE) | tee -a $DEBUGLOG kill $(cat $PIDFILE) rm -f $PIDFILE } restart() { stop start } reload() { restart } case "$1" in start) start ;; stop) stop ;; restart) restart ;; reload) reload ;; *) echo "Usage: $0 {start|stop|restart}" exit 1 esac exit $?
奇怪的是，如果我在白天启动服务或重启机器，服务就会启动并保持活着状态。

任何帮助深表感谢！
您的服务停止的原因在于您提供的日志logging：
/bin/bash rtc_client.sh start (code=exited, status=0/SUCCESS)
您的rtc_client.sh脚本正在以SUCCESS状态退出。 你应该调查你的脚本，看看为什么它不会继续运行。
