python檢查目錄文件權限并修改目錄文件權限的操作

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?？梢允褂胦s.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)
