实例如下：

# -*- 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 %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);

os.chmod(path,mode) 这个方法应该很简单，只需要2个参数，一个是路径，一个是说明路径的模式，下面列出了这个用法中可以使用的一些常用的模式：

stat.S_ISUID: Set user ID on execution. 不常用

stat.S_ISGID: Set group ID on execution. 不常用

stat.S_ENFMT: Record locking enforced. 不常用

stat.S_ISVTX: Save text image after execution. 在执行之后保存文字和图片

stat.S_IREAD: Read by owner. 对于拥有者读的权限

stat.S_IWRITE: Write by owner. 对于拥有者写的权限

stat.S_IEXEC: Execute by owner. 对于拥有者执行的权限

stat.S_IRWXU: Read, write, and execute by owner. 对于拥有者读写执行的权限

stat.S_IRUSR: Read by owner. 对于拥有者读的权限

stat.S_IWUSR: Write by owner. 对于拥有者写的权限

stat.S_IXUSR: Execute by owner. 对于拥有者执行的权限

stat.S_IRWXG: Read, write, and execute by group. 对于同组的人读写执行的权限

stat.S_IRGRP: Read by group. 对于同组读的权限

stat.S_IWGRP: Write by group. 对于同组写的权限

stat.S_IXGRP: Execute by group. 对于同组执行的权限

stat.S_IRWXO: Read, write, and execute by others. 对于其他组读写执行的权限

stat.S_IROTH: Read by others. 对于其他组读的权限

stat.S_IWOTH: Write by others. 对于其他组写的权限

stat.S_IXOTH: Execute by others. 对于其他组执行的权限

>>> os.stat('test')posix.stat_result(st_mode=33204, st_ino=93328670, st_dev=18L, st_nlink=1, st_uid=30448, st_gid=1000, st_size=0, st_atime=1445932321, st_mtime=1445932321, st_ctime=1445932321)>>> os.stat('test').st_mode33204>>> oct(os.stat('test').st_mode)'0100664'>>> oct(os.stat('test').st_mode)[-3:]'664'
