在网上找了一个定时重启tomcat的脚本,自己自动执行是可以的,但就是加入crontab后不执行。
重启脚本如下
restart_tomcat.sh
#!/bin/bash tomcat_home=/usr/local/tomcat8 SHUTDOWN=$tomcat_home/bin/shutdown.sh STARTTOMCAT=$tomcat_home/bin/startup.sh $SHUTDOWN $STARTTOMCAT
定时任务
0 2 * * * cd /opt && ./restart_tomcat.sh
定时任务执行后提示信息在/var/spool/mail/root中
cat /var/spool/mail/root
还可以在crontab的执行日志中看都执行了什么命令
tail -n 100 /var/log/cron
从提示信息中我们看见是在执行脚本的时侯没有找到JAVA_HOME
在网上也找到了一篇文章中介绍的
有时我们创建了一个crontab,然而这个任务却难以手动执行,而自动执行这个任务却没有问题,这些情况通常是因为在crontab文件中没有配置环境变量导致的。
所以就改了一下重启脚本linux定时任务不执行,加入source/etc/profile
最终的重启脚本如下
#!/bin/sh source /etc/profile tomcat_home=/usr/local/tomcat8 # 找到tomcat进程并kill掉 ps -ef |grep tomcat |awk {'print $2'} |sed -e "s/^/kill -9 /g" |sh - # 删除日志目录 # rm $tomcat_home/logs/* -rf # 删除临时目录 # rm $tomcat_home/work/* -rf # 启动tomcat start_tomcat=$tomcat_home/bin/startup.sh $start_tomcat
此次才能重启了,还是linux知识把握的太少linux定时任务不执行linux启动盘制作工具linux操作系统教程,没有系统地了解。
注意事项:crontab中要写全路径

Linux is suitable for servers, development environments, and embedded systems. 1. As a server operating system, Linux is stable and efficient, and is often used to deploy high-concurrency applications. 2. As a development environment, Linux provides efficient command line tools and package management systems to improve development efficiency. 3. In embedded systems, Linux is lightweight and customizable, suitable for environments with limited resources.

Introduction: Securing the Digital Frontier with Linux-Based Ethical Hacking In our increasingly interconnected world, cybersecurity is paramount. Ethical hacking and penetration testing are vital for proactively identifying and mitigating vulnerabi

The methods for basic Linux learning from scratch include: 1. Understand the file system and command line interface, 2. Master basic commands such as ls, cd, mkdir, 3. Learn file operations, such as creating and editing files, 4. Explore advanced usage such as pipelines and grep commands, 5. Master debugging skills and performance optimization, 6. Continuously improve skills through practice and exploration.

Linux is widely used in servers, embedded systems and desktop environments. 1) In the server field, Linux has become an ideal choice for hosting websites, databases and applications due to its stability and security. 2) In embedded systems, Linux is popular for its high customization and efficiency. 3) In the desktop environment, Linux provides a variety of desktop environments to meet the needs of different users.

The disadvantages of Linux include user experience, software compatibility, hardware support, and learning curve. 1. The user experience is not as friendly as Windows or macOS, and it relies on the command line interface. 2. The software compatibility is not as good as other systems and lacks native versions of many commercial software. 3. Hardware support is not as comprehensive as Windows, and drivers may be compiled manually. 4. The learning curve is steep, and mastering command line operations requires time and patience.
