  • ubuntu下PAC Manager使用

    windows下面经常用Secure CRT来多标签连SSH

    linux下面用PAC Manager也是想当的顺手

    支持rsa加密的key来连接

    下载地址：http://sourceforge.net/projects/pacmanager/

    怎么生成key，看之前的ssh的key的生成

    在PAC Manager使用key的认证会提示说

    @         WARNING: UNPROTECTED PRIVATE KEY FILE!          @

Permissions 0440 for '/home/jpuyy/Dropbox/key/xxxxx' are too open.
It is recommended that your private key files are NOT accessible
by others.
This private key will be ignored.

    这样的话它是希望权限规定的越死越好，那么把文件弄成400，即只允许用户的读权限，其它一律不许

    chmod 400 xxx

    这样就可以了

  • mysql启动失败

    /usr/sbin/mysqld status

    提示

    lc-messages-dir=/usr/share/mysql

    在http://www.dotdeb.org/2011/11/01/mysql-5-5-is-finally-here/ 给出了解决方法

    在my.cnf中注释掉就可以了

    "The mysql-common package will be upgraded to version 5.5.17. It’s no
big deal, it only contains retro-compatible configuration files."
Wrong. The my.cnf delivered by mysql-common-5.5 contains the
lc-messages-dir setting, which MySQL Server 5.1 cannot understand
and will fail to start.To everyone who upgraded mysql-common to 5.5,
but left mysql-server unchanged: Comment out the lc-messages-dir
setting in my.cnf OR YOUR MYSQL SERVER WILL FAIL TO START.

  • jQuery笔记

    所有jQuery位于下面函数中，为了防止文档在完全加载（就绪）之前运行 jQuery 代码

    $(document).ready(function(){

--- jQuery functions go here ----

});

    jQuery 有元素选择器和属性选择器

    买到一包假南京烟

    十一块五浪费了

    不是觉得百来块的书贵么
