py脚本 获取当前运行服务的相关信息

一.简介

最近在统计系统中都部署了什么服务，但服务器太多，在没有标准化之前进行整理，还是写脚本收集方便一些。

当然还是需要人工去判断整理表格，为后面标准化做准备。脚本是python2.7的，默认的centos系列都可以使用。

二.代码

1. #!/usr/bin/python2.7
2. #coding=utf-8
3. #通过netstat -unltp命令收集监听端口，需要客户端安装net-tools
4. #获取当前运行的服务相关信息、PID号、端口号、服务名称、目录位置
5. import json, commands, string
6. import socket, sys
7. deny_port = ["123", "22"]
8. def get_port():
9. prostr = commands.getstatusoutput('netstat -unltp')
10. prostr = str(prostr)
11. prolist = prostr.split('\\n') #用两个\才行
12. del prolist[0]
13. del prolist[0]
14. prolist = prolist[::-1]
15. info_dict = {}
16. for info in prolist:
17. port_info = info.split()
18. if len(port_info) >= 7:
19. tmp_port = port_info[3].split(':')
20. tmp_port = tmp_port.pop()
21. tmp_info = port_info[6].split('/')
22. tmp_pid = tmp_info[0]
23. if tmp_port in deny_port:
24. continue
25. if tmp_pid in info_dict.keys():
26. port_list = info_dict[tmp_pid]
27. port_list.append(tmp_port)
28. else:
29. info_dict[tmp_pid] = [tmp_port]
30. return info_dict
31. #根据字典循环去查询名称
32. def tmp_name(info_dict):
33. inq_bin = "ps -aux"
34. prostr = commands.getstatusoutput(inq_bin)
35. prostr = str(prostr)
36. prolist = prostr.split('\\n')
37. del prolist[0]
38. for i in prolist:
39. ps_info = i.split()
40. ps_pid = ps_info[2]
41. ps_name = ps_info[11:]
42. print("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
43. def get_name(info_dict):
44. #获取ps
45. inq_bin = "ps -aux"
46. prostr = commands.getstatusoutput(inq_bin)
47. prostr = str(prostr)
48. prolist = prostr.split('\\n')
49. del prolist[0]
50. for k, v in info_dict.items():
51. print("PID号: " + k)
52. print("监听的端口: " + v)
53. for i in prolist:
54. ps_info = i.split()
55. ps_pid = ps_info[1]
56. if k == ps_pid:
57. ps_name = ""
58. for n in ps_info[10:]:
59. ps_name = ps_name + " " + n
60. print("运行用户: " + ps_info[0])
61. print("服务名称: " + ps_name)
62. exe_dir = "ls -l /proc/" + k + "/exe"
63. exes = commands.getstatusoutput(exe_dir)
64. exes = str(exes)
65. exes_list = exes.split()
66. cwd_dir = "ls -l /proc/" + k + "/cwd"
67. cwds = commands.getstatusoutput(cwd_dir)
68. cwds = str(cwds)
69. cwds_list = cwds.split()
70. print("目录位置: " + exes_list[11] + " 或者 " + cwds_list[11])
71. print("+++++++++++++++++++++++++++++++++")
72. info_dict = get_port()
73. get_name(info_dict)
