python脚本自动监视重启tomcat进程

#!/usr/bin/python  
import subprocess  
import datetime  
res = subprocess.Popen(“ps -ef | grep tomcat”,stdout=subprocess.PIPE,shell=True)  
tomcats=res.stdout.readlines()  
counts=len(tomcats)  
if counts<4:  
dt=datetime.datetime.now()  
fp=open(‘/root/tomcat6.txt’,'a’)  
fp.write(‘tomcat6 stop at %s\n’ % dt.strftime(‘%Y-%m-%d %H:%M:%S’))  
fp.close()  
subprocess.Popen(“/opt/tomcat7.0/bin/startup.sh”,shell=True)  

30分钟检查一次,如果线程不再就重启

用定时运行该脚本。

/etc/crontab

crontab -e:
*/30 * * * * root python /root/autorestart-tomcat.py
