ansible-playbook 远程启动程序

远程启动程序后ansible执行成功后程序被关闭

今天写个ansible-playbook部署war，unarchive包时很正常就是在重启tomcat的脚本怎么也启动不起来，后来经过测试发现tomcat有启动，因为公司tomcat没有做成服务，所以得使用tomcat脚本去启动，例:(/home/a/app/tomcat/bin/catalina.sh start) 记得要把bin目录下面所有sh都授成可执行权限(chmod u+x *.sh)，但是当ansible正常退出时tomcat进程被关闭，怀疑是ansible fork出来子线程来运行脚本，ansible正常退出时会结束所有fork的子线程，这设计也是对的，解决方法在下面

解决方法

因为tomcat启动后被关闭，想到是不是让tomcat在后台运行就可以，后经过测试想法是正常的解决方法，代码如下:


nohup su - fuck /home/a/tomcat/bin/catalina.sh start 1>2& &


重启tomcat 脚本(python,shell)

python


import os
import sys
import time

tomcat_path = sys.argv[1]
tomcat_user = sys.argv[2]

if not os.path.exists(tomcat_path):
print(“tomcat目录不存在”)
sys.exit(0)

index = 0

def get_tomcat_pid():
return os.popen(“ps axu|grep tomcat|grep -v grep |grep \”%s\”|grep -v python|awk ‘{print $2}’” % tomcat_path).read()

def stop_tomcat(index=0):
temp_tomcat_pid = get_tomcat_pid()
print(“temp_tomcat_pid:”, temp_tomcat_pid)
if not temp_tomcat_pid:
return 0
pid = int(temp_tomcat_pid.replace(“\n”, “”).strip())

if index <= 9:
    return pid

time.sleep(1)
index += 1

if int(pid) > 0:
    os.popen("%s/%s" % (tomcat_path, "bin/catalina.sh stop"))
    stop_tomcat()

tomcat_pid = stop_tomcat()

def force_kill_tomcat():
os.popen(“kill -9 %s” % tomcat_pid)

def start_tomcat():
os.popen(“nohup su - %s %s%s 1>&2 &” % (tomcat_user, tomcat_path, “bin/catalina.sh start”))
time.sleep(5)
return os.popen(“tail -n 100 %s” % (tomcat_path + “logs/catalina.out”)).read()

if tomcat_pid > 0:
print(“强制停止tomcat”)
force_kill_tomcat()

start_tomcat()
