这篇文章主要介绍了python检查目录文件权限并修改目录文件权限的操作，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧
我就废话不多说了，还是直接看代码吧！
# -*- coding: utf-8 -*- # @author flynetcn import sys, os, pwd, stat, datetime; LOG_FILE = '/var/log/checkDirPermission.log'; nginxWritableDirs = [ '/var/log/nginx', '/usr/local/www/var'<div style="color:transparent">来源gaodai^.ma#com搞#代!码网</div>, ]; otherReadableDirs = [ '/var/log/nginx', '/usr/local/www/var/log', ]; dirs = []; files = []; def logger(level, str): logFd = open(LOG_FILE, 'a'); logFd.write(datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S.%f')+": "+("WARNING " if level else "NOTICE ")+str); logFd.close(); def walktree(top, callback): for f in os.listdir(top): pathname = os.path.join(top, f); mode = os.stat(pathname).st_mode; if stat.S_ISDIR(mode): callback(pathname, True); walktree(pathname, callback); elif stat.S_ISREG(mode): callback(pathname, False); else: logger(1, "walktree skipping %s\n" % (pathname)); def collectPath(path, isDir=False): if isDir: dirs.append(path); else: files.append(path); def checkNginxWritableDirs(paths): uid = pwd.getpwnam('nginx').pw_uid; gid = pwd.getpwnam('nginx').pw_gid; for d in paths: dstat = os.stat(d); if dstat.st_uid != uid: try: os.chown(d, uid, gid); except: logger(1, "chown(%s, nginx, nginx) failed\n" % (d)); def checkOtherReadableDirs(paths, isDir=False): for d in paths: dstat = os.stat(d); if isDir: checkMode = 5; willBeMode = dstat.st_mode | stat.S_IROTH | stat.S_IXOTH; else: checkMode = 4; willBeMode = dstat.st_mode | stat.S_IROTH; if int(oct(dstat.st_mode)[-1:]) & checkMode != checkMode: try: os.chmod(d, willBeMode); except: logger(1, "chmod(%s, %d) failed\n" % (d, oct(willBeMode))); if __name__ == "__main__": for d in nginxWritableDirs: walktree(d, collectPath) dirs = dirs + files; checkNginxWritableDirs(dirs); dirs = []; files = []; for d in otherReadableDirs: walktree(d, collectPath) checkOtherReadableDirs(dirs, True); checkOtherReadableDirs(files, False);
补充知识：Python中获取某个用户对某个文件或目录的访问权限
在Python中我们通常可以使用os.access()函数来获取当前用户对某个文件或目录是否有某种权限，但是要获取某个用户对某个文件或目录是否有某种权限python中没有很好的方法直接获取，因此我写了个函数使用stat和pwd模块来实现这一功能。
#!/usr/bin/env python # -*- coding: utf-8 -*- import os import pwd import stat def is_readable(path, user): user_info = pwd.getpwnam(user) uid = user_info.pw_uid gid = user_info.pw_gid s = os.stat(path) mode = s[stat.ST_MODE] return ( ((s[stat.ST_UID] == uid) and (mode & stat.S_IRUSR > 0)) or ((s[stat.ST_GID] == gid) and (mode & stat.S_IRGRP > 0)) or (mode & stat.S_IROTH > 0) ) def is_writable(path, user): user_info = pwd.getpwnam(user) uid = user_info.pw_uid gid = user_info.pw_gid s = os.stat(path) mode = s[stat.ST_MODE] return ( ((s[stat.ST_UID] == uid) and (mode & stat.S_IWUSR > 0)) or ((s[stat.ST_GID] == gid) and (mode & stat.S_IWGRP > 0)) or (mode & stat.S_IWOTH > 0) ) def is_executable(path, user): user_info = pwd.getpwnam(user) uid = user_info.pw_uid gid = user_info.pw_gid s = os.stat(path) mode = s[stat.ST_MODE] return ( ((s[stat.ST_UID] == uid) and (mode & stat.S_IXUSR > 0)) or ((s[stat.ST_GID] == gid) and (mode & stat.S_IXGRP > 0)) or (mode & stat.S_IXOTH > 0) )
使用方法
print is_readable('/home', root) print is_writable('/home', root) print is_executable('/home', root) print is_readable('/tmp', admin) print is_writable('/tmp', admin) print is_executable('/tmp', admin)
