Centos 定时重启 tomcat 服务的方法场景某一天客户突然跟我说单机服务请求失败，我一看情况，是 tomcat 挂了，但是日志却没有任何报错信息，用 top 命令查看也没发现啥问题，直接重启之后并没有啥问题，于是我就猜想会不会是运行太长时间，有一些程序内部出了异常，但是没有抛出来，短时间定位不到问题，于是我就想着，先把 tomcat 做个定时重启，确保每天服务都正常运行。正文重启tomcat的shell脚本 #!/bin/bash . /etc/profile tomcatPath="这里放tomcat的路径" binPath="$tom 阅读详情

大家好，我的一个脚本用crontab定时运行，我做了如下操作：
1. crontab -e
2. 添加内容 1 * * * * /home/my_path/getIp.sh (每小时的第一分钟执行)
3. wq 保存

头几个小时挺稳定的，后来就不执行了，我用crontab -e 看了一下，里面多了几千行很多东西，而且我添加的任务也被冲掉了，crontab -e 显示如下：
s file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
# Edit this file to introduce tasks to be run by cron.
# Edit this file to introduce tasks to be run by cron.

。。。。。。
后面还有几千行

请问这是怎么回事啊，我的操作方法不对吗，请帮忙指教一下，谢谢大家了！
