MySQL 5.1.54 Ubuntu 11.04

我尝试将my.conf中的bin日志目录更改为:

[mysqld]
log_bin=/home/developer/logs/mysql/mysql-bin.log

在此更改后MySQL服务器无法启动错误:

/usr/sbin/mysqld: File '/home/developer/logs/mysql/mysql-bin.index' 
not found (Errcode: 13)
111005 12:47:58 [ERROR] Aborting

目录/ home/developer/logs/mysql /的权限是0777

这是怎么回事？

我想在几个线程中使用进程消息但是在执行此代码时我遇到错误:

from __future__ import with_statement
import pika
import sys
from pika.adapters.blocking_connection import BlockingConnection
from pika import connection, credentials
import time
import threading
import random
from pika.adapters.select_connection import SelectConnection
from pika.connection import Connection
import traceback


def doWork(body, args, channel):


    r = random.random()
    time.sleep(r * 10)
    try:        
        channel.basic_ack(delivery_tag=args.delivery_tag)

    except :
        traceback.print_exc()


auth = credentials.PlainCredentials(username="guest", password="guest")
params = connection.ConnectionParameters(host="localhost", credentials=auth)
conn = BlockingConnection(params)
channel = conn.channel()


while True:

    time.sleep(0.03)    
    try:

        method_frame, header_frame, body = channel.basic_get(queue="test_queue")
        if method_frame.NAME == 'Basic.GetEmpty':
            continue        

        t = threading.Thread(target=doWork, …

有没有办法将选项定义为包含空格的字符串,如下所示

$myscript.php test --comment="some string"

它输出:

[RuntimeException]   
Too many arguments.

test [-c|--comment="..."]

但是,如果--comment不包含空格(例如:"some_string"),则它可以工作.
