由于tomcat开始集群，部署较为不变，于是写了个python自动化更新备份脚本

            #
            !/usr/local/bin/python3
            
#
            coding:utf-8
            import
             os, sys, subprocess, time, shutil

site_file = ‘xxxxxi‘
update_file = ‘/home/sourcedir/‘ + site_file + ‘.war‘
webapps_file = ‘/var/tomcat2/webapps/‘ + site_file + ‘.war‘
webapps_dir = ‘/var/tomcat2/webapps/‘ + site_file
bakwebapps_file = ‘/var/tomcat2/bakwebapps/‘ + site_file + ‘.war‘
bakwebapps_dir = ‘/var/tomcat2/bakwebapps/‘ + site_file

tomcat_pid =  ((subprocess.Popen("lsof -i :8081 |grep root |awk ‘{print $2}‘", shell=True, stdout=subprocess.PIPE)).stdout.read()).decode()

print("Tomcat will shutdown after 6s, u can enter Ctrl + c interrupt it ! ")
for i in range(3):
    print("." ,end = "")
    sys.stdout.flush()
    time.sleep(1)

print()
if len(tomcat_pid) == 0:
    print("> tomcat already shutdown!")
else:
    subprocess.Popen("/usr/local/tomcat/bin/shutdown.sh > /dev/null 2>&1", shell=True, stdout=subprocess.PIPE)

for i in range(3):
    print("." ,end = "")
    sys.stdout.flush()
    time.sleep(1)
    
if len(tomcat_pid) == 0: 
    passelse :
   subprocess.Popen("kill -9 " + tomcat_pid, shell=True, stdout=subprocess.PIPE)
   print("\n> Tomcat close the failure, kill the pid %s" % tomcat_pid) 
   
#备份旧站点print("\n--------Begin to backup webapps---------\n")
 
if os.path.exists(bakwebapps_file):
    shutil.rmtree(bakwebapps_dir)
    print("> Old bak webapps has been deleted!")
    os.remove(bakwebapps_file)
else:
    pass


shutil.copyfile(webapps_file, bakwebapps_file)    
shutil.copytree(webapps_dir, bakwebapps_dir)
for i in range(3):
    print("." ,end = "")
    sys.stdout.flush()
    time.sleep(1)
print("\n> Backup completed，Start to update the program...")
shutil.copyfile(update_file, webapps_file)

print("\n> Update completed,start tomcat")
subprocess.Popen("/usr/local/tomcat/bin/startup.sh", shell=True, stdout=subprocess.PIPE)

for i in range(3):
    print("." ,end = "")
    sys.stdout.flush()
    time.sleep(1)
tomcat_pid2 =  ((subprocess.Popen("lsof -i :8081 |grep root |awk ‘{print $2}‘", shell=True, stdout=subprocess.PIPE)).stdout.read()).decode()

if len(tomcat_pid2) == 0:
    print("\n> Tomcat has not start, Please check u program!")
else:
    print("\n> Tomcat have already started !")

 

END!
