jmeter服务脚本。重新启动不起作用

Question

我正在尝试在CentOS 6.6上为apache jmeter使用以下服务脚本。

#!/bin/sh 
### BEGIN INIT INFO 
# chkconfig:   2345 85 15 
# Provides:   jmeter-server 
# Required-Start: $syslog $local_fs 
# Required-Stop:  $syslog $local_fs

# Default-Stop:  0 1 6 
# Short-Description: Apache JMeter Remote Server 
# Description:  Apache JMeter Remote Server runs JMeter tests issued from a remote server. 
### END INIT INFO

# Change this to your IP 
export RMI_HOST_DEF="-Djava.rmi.server.hostname=10.0.2.15" 
SCRIPTNAME=/etc/init.d/$NAME 
JAVA_PID=$(pgrep -f "[A]pacheJMeter.jar $RMI_HOST_DEF -Dserver_port=1099")

     [ $RETVAL = 0 ] && touch /var/lock/subsys/$NAME 
}

} 

#

# 
do_restart() 
{ 
     do_stop 
     do_start 
} 

case "$1" in 
    start) 
     do_start 
     ;; 
    stop) 
     do_stop 
     ;; 
    status)

     [ -e /var/lock/subsys/$NAME ] && do_restart 
     ;; 
    *) 
     echo "Usage: $SCRIPTNAME {start|stop|status|restart|force-reload}" >&2 
     exit 3 
     ;; 
esac 

exit $RETVAL 

服务JMeter的启动和服务JMeter的停止工作正常，但是当我尝试做服务JMeter的重新启动，则停止Java实例，但因为它认为JMeter是已经运行它不再次启动。

任何指针，将不胜感激。

你是不是重置/停止更新之间和JAVA_PID启动命令，所以start基于以下条件将退出：

[ -n "$JAVA_PID" ] && echo "$NAME already started" && exit 0 

你需要阻止它，例如后或者复位/更新JAVA_PID

update_pid() 
{ 
    JAVA_PID=$(pgrep -f "[A]pacheJMeter.jar $RMI_HOST_DEF -Dserver_port=1099") 
} 
... 
do_restart() 
{ 
    do_stop 
    update_pid 
    do_start 
}
