在重启服务前先检查服务是否在运行，通过grep命令（-v排除带有grep字符串的行）过滤出服务进程的pid，如果有就先杀掉进程，清除日志，最后启动服务并指定日志输出位置
#!/bin/sh
d=`ps -ef|grep match-0.4.41.jar | grep -v grep | awk '{print $2}'`
if [ "$d" = "" ]
then
echo "撮合进程未启动"
else
kill -9 $d
echo "${d}进程终止成功"
fi
d1=`ps -ef|grep liquidation-0.4.44.jar | grep -v grep | awk '{print $2}'`
if [ "$d1" = "" ]
then
echo "爆仓进程未启动"
else
kill -9 $d1
echo "${d1}进程终止成功"
fi
rm -f *.log
echo "日志已清除："
nohup java -jar liquidation-0.4.44.jar >>./liq.log 2>&1 &
echo "爆仓服务已重启"
nohup java -jar match-0.4.41.jar >>./mat.log 2>&1 &
echo "撮合服务已重启"
