搜了一下，好多人遇到此问题，大致是mysql版本不通造成的，以下是解决办法：
mysql>UPDATE mysql.user SET Password = OLD_PASSWORD('yourpass') WHERE Host = 'localhost' AND User = 'username';
mysql>FLUSH PRIVILEGES;

这里是mysql官方的解释！

试过了安全模式居然也无法进入。。。
无语了

去其他电脑google了一番，发现怎么解释的都有，不过都不靠谱、再说不靠谱的事也并不适合我，
回想起来最近的操作，最令我感到怀疑的就是昨晚勤劳勇敢的卡巴曾经提示有个dll文件是木马，问我是否删除，哎！想都没想就点击了删除。工作到深夜，合上本就睡了。

早上，忙，很多事情堆到了一起，没有电脑，工作真是没法进行啊！
赶紧把破本还给了IT去检查，先借了一个更破的本本用先，可惜是个裸奔，嘛软件也木有，麻烦死了，我的n多环境的安装啊，不过也没有办法，凑合先用着吧。。

中午过后，IT大哥下山，结果出炉，本本重装，C盘格掉，其他保留！

不错的结果，我很满意！想想如果是硬盘挂掉，等着哭吧就。

送各位一句金玉良言：卡巴虽好，也不尽可信，备份麻烦，真的重要啊！

我吃了一惊，心里暗暗赞许，这才是真爷们，有胆量、敢表白，众目睽睽之下居然如此这般、这般如此！

那手机也真是油品味，衰呆了、呕像！

手机闪着七彩的光芒，还伴随着美妙的音乐 --- 亲爱的，你慢慢飞，小心前面带刺的玫瑰！（让我想起了小品里说的，瞎啊！往刺上撞？）

那音响效果超赞，绝对立体声，如果再接个功放，那是相当有感觉，绝对可以达到院线效果。

我们一路走，丫的一路放，我的这个心啊，都碎了！

我无语，我崩溃，那些歌曲真的让我听的好累！

丫丫个呸的，这就是所谓的MTK！

这一路翻来覆去的《无所谓》整我直反胃！

终于到站，俺要下车了，机会终于来了，

憋了50分钟的我终于有了表达自己心意的机会了，

俺深情地望了一下这对神仙般摇头晃脑的鸳鸯，

还有那部超牛B的泛着神的光芒的山寨机，

我咬了咬嘴唇，浑身战栗着，

思绪万千，化作无言的泪水，

最后终于在汽车将近关门的一刹那，俺直挺挺、恶狠狠的抛出一句话：

大哥，你的山寨机很好，很弓虽大，哪儿买地？

nagios的check_ping命令：
源码可见 nagios插件： nagios-plugins-1.4.12/plugins/check_ping.c
 
用法：
./check_ping 
Usage: check_ping -H <host_address> -w <wrta>,<wpl>% -c <crta>,<cpl>%
                     [-p packets] [-t timeout] [-L] [-4|-6]
具体如下：
-H    主机地址
-w    WARNING 状态：  响应时间(毫秒)，丢包率 (%)   阀值
-c    CRITICAL状态：    响应时间(毫秒)，丢包率 (%)   阀值
-p    发送的包数           默认5个包
-t     超时时间             默认10秒
-4|-6                        使用ipv4|ipv6 地址      默认ipv4
 
如：
1、正常：
./check_ping -H www.google.com -w 100.0,20% -c 200.0,50% -p 3 -t 2
PING OK - Packet loss = 0%, RTA = 1.49 ms
命令执行结果返回： echo $?   为 0
2、WARNING ：
./check_ping -H www.google.com -w 0.1,20% -c 200.0,50% -p 3 -t 2
PING WARNING - Packet loss = 0%, RTA = 1.71 ms
命令执行结果返回： echo $?   为 1
3、CRITICAL
./check_ping -H www.google.com -w 0.1,20% -c 0.9,50% -p 3 -t 2
PING CRITICAL - Packet loss = 0%, RTA = 1.60 ms
命令执行结果返回： echo $?   为 2
 
返回结果为：状态  丢包率 ping响应时间
因为check_ping的返回值非常清晰，
可以在其他程序中调用check_ping命令，作为辅助的网络检测工具。
