1、编辑一个脚本
vi /usr/local/watchicomet.sh
#!/bin/bash
sn=`ps -ef | grep ./icomet-server | grep -v grep |awk '{print $2}'`
echo $sn
if [ "${sn}" = "" ] #如果为空,表示进程未启动
then
nohup service icomet start > icomet.log 2>&1 & #后台启动进程
echo start icomet success!
else
echo icomet is running!
fi
2、给上执行权限
chmod +x watchicomet.sh
3、设置每1分钟检查一次
echo "*/1 * * * * root /usr/local/watchicomet.sh > /dev/null 2>&1">>/etc/crontab
