今天写了一个定时重启tomcat的脚本
定时任务：
30 * * * * /bin/bash /root/scripts/auto_restart_tomcat5.sh >> /root/scripts/auto_restart_tomcat5.log 2>&1 &
首先进行判断进程是否存在，存在则进行kill，不存在则启动；
如此循环；
启动后break跳出循环；
#!/bin/sh#date 2019-12-11#dan si#auto restart tomcat5
time=`date "+%Y-%m-%d %H:%M:%S"` echo -e "\n\n===============================" echo "======$time======" echo "===============================" serviceName=tomcat5/conf pid=`ps -ef | grep $serviceName | grep -v "grep" | awk '{print $2}'` #kill -9 $pid for((i=1;i<100;i++)); do if [ 0 == `ps -ef |grep $serviceName |grep -v "grep" |wc -l` ];then echo "$serviceName process is no running!" cd /usr/local/tomcat5/ ./bin/catalina.sh start echo "$serviceName process is restart!" break else kill -9 $pid echo "$serviceName process is running! It was killed again" sleep 1 fi done
