The path "" is not valid path to the gcc binary. Would you like to change it? [yes] 

when typed in "/usr/bin/gcc" manually,

The path "/usr/bin/gcc" is not valid path to the gcc binary. Would you like to change it? [yes]

I found solution:

http://superuser.com/questions/192047/gcc-path-not-valid-when-installing-vmware-tools-from-vmware-workstation-7-1-1-bu

ie: sudo apt-get install linux-source linux-headers-uname -r libglib2.0-0

// Got “If you wish to have the shared folders feature, you can install the driver by running vmware-config-tools.pl again after making sure that gcc, binutils, make and the kernel sources for your running kernel are installed” before install “linux-source”.

I HATE kdewallet (kwallet)

2012-03-31. Category & Tags: Life, Soft&Skills Life, Soft&Skills

XX的kde, 你以为你是微软啊, 乱给用户装东西!!!

卸载了半天, 一直找不到该卸载什么,最后只好这么办:

apt-get install kwalletmanager

运行 kwalletmanager, 设置里面 uncheck “enable kwallet subsys”.

 

乱码putty支持中文utf8输入和显示

2012-03-22. Category & Tags: Leading, Soft&Skills Leading, Soft&Skills

ref: networkquestions.org

Note: Putty officially recommends to use Bitvise SSH Client & Server.

终端默认是使用windows的编码方式（GBK），我们需要手动改为UTF-8

再次重启的时候就不会是乱码了：

[root@mail ~]# service httpd restart
停止 httpd：                                               [确定]
启动 httpd：                                               [确定]
[root@mail ~]#

这是终端的乱码问题，再说一下打开中文文件乱码问题。

在很多的配置文件中，含有中文，用vi打开时也是会乱码。首先我们系统中要有中文语言显示包（fonts-chinese），否则改为UTF-8也是会乱码。
[root@mail ~]# cat /etc/sysconfig/i18n
LANG=”zh_CN.UTF-8″
[root@mail ~]#
上面的设置，系统语言为中文，如果想改为英文的话，替换为：

LANG=”en_US.UTF-8″  保存即可。

临时性改变语言：export LANG=en_US.UTF-8

echo $LANG   //查看语言

另一个:

ref: ylmf.net

字符乱码:

在window-〉Appearance-〉Translation中，Received data assumed to be in which character set 中,把Use font encoding改为UTF-8.

如果经常使用,把这些设置保存在session里面.

/* 下面的有待研究 ….

登录成功后,在shell中输入:export LC_ALL=‘zh_CN.utf8’,现在已经可以完美的支持中文了.

打开putty主程序，选择window-〉Appearance-〉Font settings-〉Change…,选择Fixedsys字体,字符集选择CHINESE_GB2312。

默认情况下，putty对中文的支持却让人不敢恭维，如果远程linux的locale设置为zh_CN.*(bg2312,gbk,utf8等等)，显示就是乱码。经研究发现，其实putty的中文支持还是很好的，呵呵

最近接触了下淘宝的性能框架PAP，觉得系统中的监控真的做的很不错，但是非pap运行的程序，则无法监控，同时也查了下淘宝性能百科对监控命令Sar介绍，觉得讲的比较粗，这里把自己以前用过的Sar监控分享下；有问题，大家共勉哈！
