我就廢話不多說了，還是直接看代碼吧！

# -*- coding: utf-8 -*-# @author flynetcnimport sys, os, pwd, stat, datetime; LOG_FILE = ’/var/log/checkDirPermission.log’; nginxWritableDirs = [’/var/log/nginx’,’/usr/local/www/var’,]; 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 %sn' % (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) failedn' % (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) failedn' % (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);

補充知識：Python中獲取某個用戶對某個文件或目錄的訪問權限

在Python中我們通常可以使用os.access()函數來獲取當前用戶對某個文件或目錄是否有某種權限，但是要獲取某個用戶對某個文件或目錄是否有某種權限python中沒有很好的方法直接獲取，因此我寫了個函數使用stat和pwd模塊來實現這一功能。

#!/usr/bin/env python# -*- coding: utf-8 -*-import osimport pwdimport statdef 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)

以上這篇python檢查目錄文件權限并修改目錄文件權限的操作就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持好吧啦網。
