分割catalina.out 每天生成一个文件

2. vim xxx.sh
写入 -----------------------
#!/bin/sh
cd `dirname $0`
pwd
d=`date +%Y%m%d`
d7=`date -d'7 day ago' +%Y%m%d`
cd ../logs/
cp catalina.out catalina.out.${d}
cat /dev/null > catalina.out
rm -rf catalina.out.${d7}
------------------------- (这个是删除七天以前的log)
路径做对应修改
3. chmod
-R 777 xxx.sh
4. vim /etc/crontab
在文件最后 0 2 * * * root /usr/local/wfjb_web_back/xxx.sh
