import 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);

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_vnsc5858威尼斯城官网,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_mode
33204
>>> oct(os.stat('test').st_mode)
'0100664'
>>> oct(os.stat('test').st_mode)[-3:]
'664'
