编写shell脚本实现tomcat定时重启的方法_linux shell_

 vim tomcatStart.sh 

 #!/bin/bash /etc/profile tomcatPath="/usr/local/tomcat9" binPath="$tomcatPath/bin" echo "[info][$(date)]正在监控tomcat，路径：$tomcatPath" pid=`ps -ef | grep tomcat | grep -w $tomcatPath | grep -v 'grep' | awk '{print $2}'` if [-n "pid"]; then echo "[info][$(date)]tomcat进程为：$pid" echo "[info][$(date)]tomcat已经启动，准备使用shutdown命令关闭" $binPath"/shutdown.sh" sleep 2 pid=`ps -ef | grep tomcat | grep -w $tomcatPath | grep -v 'grep' | awk '{print $2}'` if [-n "$pid"]; then echo "[info][$(date)]使用shutdown关闭失败，准备kill进程" kill -9 $pid echo "[info][$(date)]kill进程完毕" sleep 1 else echo "[info][$(date)]使用shutdown关闭成功" fi else echo "[info][$(date)]tomcat未启动" fi echo "[info][$(date)]准备启动tomcat" $binPath"/startup.sh" 

 sudo chmod 777 tomcatStart.sh

 crontab -e // 第一个是 tomcatStart.sh 的路径， 第二个是将日志输出到某个文件中 00 03 * * * /usr/local/tomcat9/bin/tomcatStart.sh >> /home/zhang/tomcatLog.txt

 systemctl restart crond
