office2016及visio2016的安装

新版本office不像以前的版本可以自定义安装界面供用户选择，而是点击安装后自动在后台运行，一键安装完毕，如果需要自定义，则需要下载一个工具officedeploymenttool_7614-3602.exe（Office 2016 Deployment Tool）下载地址： https://www.microsoft.com/en-us/download/details.aspx?id=49117 下载完毕后运行会让用户选择一个目录，它自动把两个文件（setup.exe、configuration.xml）解压到指定目录，编辑 configuration.xml 这个文本文件，填好相关自定义内容，再执行 setup.exe 即可自定义安装，此外还可以同时安装office和visio。之前为了同时安装office和visio下载了 cn_office_professional_plus_2016_x86_x64_dvd_6969182.iso 和 cn_visio_professional_2016_x86_x64_dvd_6970929.iso ，只执行前者，是没有visio的，需要运行两个，但实际上两个iso大小几乎一样，里面的内容估计都已经自带。使用 officedeploymenttool_7614-3602.exe 解压出来的 setup.exe 和 configuration.xml，执行 setup.exe /configure configuration.xml ，（管理员权限命令行，或者普通权限会自动弹出是否允许），注意xml里面的路径需要可识别，开始尝试 E:\某中文名文件夹\...\cn_visio_professional_2016_x86_x64_dvd_6970929\ ，结果出现提示 error code 0-1008(0) （officedeploymenttool_7614-3602.exe解压到同一目录运行时没这个错误），于是直接放到E盘下： E:\cn_visio_professional_2016_x86_x64_dvd_6970929\ ，里面的 是注释，OfficeClientEdition选择64位版本还是32位版本。参考： http://blog.sina.com.cn/s/blog_a652eb210102wkd4.html http://blog.sina.com.cn/s/blog_489988100102w4mf.html https://answers.microsoft.com/en-us/msoffice/forum/msoffice_install-mso_win10/why-doesnt-office-2016-pro-plus-setup-give-you-the/46217e78-fc40-41f8-81a7-1eb122a1bdde https://technet.microsoft.com/en-us/library/jj219423(v=office.15)?f=255&MSPPError=-2147217396 https://technet.microsoft.com/en-us/library/jj219426 简单总结一下过程： 1.下载 cn_visio_professional_2016_x86_x64_dvd_6970929.iso 解压到可识别目录例如 E:\cn_visio_professional_2016_x86_x64_dvd_6970929\，同时下载 officedeploymenttool_7614-3602.exe 运行解压到某目录； 2.编辑 officedeploymenttool_7614-3602 的 configuration.xml ，修改相关内容，如32还是64位版本，安装源所在路径，语言，安装产品（VisioProRetail、proplusretail），安装哪些组件、排除哪些组件等； 3.运行 officedeploymenttool_7614-3602 的 setup.exe 一键安装，具体命令：setup.exe /configure configuration.xml ，最后进行破解使用。 以下是本次安装使用的 configuration.xml （仅供参考）： 最后附一个Microsoft软件下载网站： http://msdn.itellyou.cn/

putty color scheme（putty配色方案）

参考： https://darekkay.com/2015/03/21/my-putty-color-scheme/ putty自带配色不太好用，特别是紫色，时间长了闪瞎眼，手动设置可以在 window -> colours 里面调整，但是太麻烦，可以直接把相关的 **.reg 导入Windows注册表即可，于是上网搜了下网友给出的诸多 color scheme，发现如下方案比较好（https://darekkay.com/2015/03/21/my-putty-color-scheme/）： Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions\SESSION_NAME] ; Default Foreground "Colour0"="217,216,216" ; Default Bold Foreground "Colour1"="217,216,216" ; Default Background "Colour2"="28,28,28" ; Default Background "Colour3"="28,63,149" ; Cursor Text "Colour4"="28,28,28" ; Cursor Color "Colour5"="231,231,232" ; ANSI Black "Colour6"="115,113,113" ; ANSI Black Bold "Colour7"="115,113,113" ; ANSI Red "Colour8"="251,38,8" ; ANSI Red Bold "Colour9"="251,38,8" ; ANSI Green "Colour10"="167,226,46" ; ANSI Green Bold "Colour11"="167,226,46" ; ANSI Yellow "Colour12"="102,217,238" ; ANSI Yellow Bold "Colour13"="102,217,238" ; ANSI Blue "Colour14"="0,157,220" ; ANSI Blue Bold "Colour15"="0,157,220" ; ANSI Magenta "Colour16"="255,85,255" ; ANSI Magenta Bold "Colour17"="255,85,255" ; ANSI Cyan "Colour18"="255,210,4" ; ANSI Cyan Bold "Colour19"="255,210,4" ; ANSI White "Colour20"="217,216,216" ; ANSI White Bold "Colour21"="255,255,255" 其中的 SESSION_NAME 替换为session名，如果注入默认设置，可将 SESSION_NAME 替换为 Default%20Settings 以上是有注释的，去掉注释的版本为： Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions\SESSION_NAME] "Colour0"="217,216,216" "Colour1"="217,216,216" "Colour2"="28,28,28" "Colour3"="28,63,149" "Colour4"="28,28,28" "Colour5"="231,231,232" "Colour6"="115,113,113" "Colour7"="115,113,113" "Colour8"="251,38,8" "Colour9"="251,38,8" "Colour10"="167,226,46" "Colour11"="167,226,46" "Colour12"="102,217,238" "Colour13"="102,217,238" "Colour14"="0,157,220" "Colour15"="0,157,220" "Colour16"="255,85,255" "Colour17"="255,85,255" "Colour18"="255,210,4" "Colour19"="255,210,4" "Colour20"="217,216,216" "Colour21"="255,255,255"

MySQL的迁移

前天从原Ubuntu把某数据库迁移到新装Ubuntu虚拟机，开始以为每个数据库是一个独立文件夹，例如自带的 /var/lib/mysql/mysql/、/var/lib/mysql/performance_schema/，自己创建的数据库**，于是只迁移了**，其余没理，后来发现原来mysql中创建的用户没了，于是新建了用户： create user 'username'@'localhost' identified by 'password'; grant all privileges on name_of_db.* to 'username'@'localhost'; 接下来发现进去数据库**后能看到表，但是列不出表的内容，查了下，原来数据库内容不在**文件夹，仔细一看，**文件夹很小，几十万条数据不可能存在里面，一查原来mysql数据库默认都是放在 ibdata1 这个文件里面的，新ibdata1大小只有18M，原有ibdata1有90M。如果需要每个数据库单独存储，则需要设置，今天重新查了下，使用 show global variables; 里面显示的选项 innodb_file_per_table 默认 OFF，开启此项后默认存放在每个数据库的文件夹里，每个表单独一个文件。 于是将原有的 ibdata1 移动到新机，终于可以看到数据了，但是发现数据不全，前天睡前想了想，要仔细看下数据，看创建时间，以及对应的ID是否和log一致，昨天早上一看是OK的，之前吓了一跳，以为几个月来爬到的东西全没了。 总结下经验，移动数据库要么导出数据导入另一机器的数据库，或者使用mysql自带数据库迁移、复制之类的功能，要么将相关文件夹和文件全部移动或复制，包括 /var/lib/mysql/mysql/、/var/lib/mysql/performance_schema/、**自己的数据库、ibdata1、ib_logfile0、ib_logfile1，这些相关的文件都需要保留。

MySQL Connector/Python 的安装

MySQL Connector/Python 是Python的mysql驱动，安装这个驱动之后才能在Python中使用 import mysql.connector 并使用数据库，具体参见 https://dev.mysql.com/doc/connector-python/en/ 安装方法可以是apt，或者下载安装包。 先说说apt。Ubuntu默认是没有mysql-connector-python这些东西的，apt-cache search mysql-connector-python是没结果的，即使 sudo apt-get update 更新后也不行，mysql相关的东西需要安装 MySQL APT Repository 让apt知道mysql相关的东西后才能用apt安装 mysql-connector-python （参考 https://dev.mysql.com/doc/mysql-apt-repo-quick-guide/en/ 、 https://dev.mysql.com/downloads/repo/apt/）。 另一种方式是下载安装包，Ubuntu是deb包（https://dev.mysql.com/downloads/connector/python/），命令 sudo dpkg -i PACKAGE.deb 安装。 以上两种是通过MySQL官网给出的安装方法，也可通过Python途径获取：使用Python安装工具pip安装。 不管是apt还是deb安装包，都有两种选择，一个是纯Python实现，另一种是C扩展实现，在操作数据量大的时候第二种效率高， import mysql.connector 默认使用第一种，连接数据库时 use_pure=False 表示使用第二种，或者直接 import _mysql_connector 使用第二种。参考（https://dev.mysql.com/doc/connector-python/en/connector-python-installation.html 、 https://dev.mysql.com/doc/connector-python/en/connector-python-example-connecting.html 、 https://dev.mysql.com/doc/connector-python/en/connector-python-cext.html）经过摸索，如果只装mysql-connector-python-cext，那么就只能使用 import _mysql_connector ，如果安装 mysql-connector-python ，则可使用 import mysql.connector ，两者都装，才可 import mysql.connector 后 设置 use_pure ，后面找了下，在这里有叙述对于Linux两个安装包是分开的，如需要则两个都要安装：https://dev.mysql.com/doc/connector-python/en/connector-python-installation-binary.html 由于自己的程序操作数据量暂不大，但考虑以后扩展性，最后选择 mysql-connector-python 和 mysql-connector-python-cext 都安装，但使用 import mysql.connector 且默认 use_pure

Ubuntu安装C/C++编译环境

Ubuntu（包括其他版本Linux）安装C/C++编译器/编译环境只需要安装build-essential即可，build-essential依赖make、gcc、g++等库，安装build-essential后这些自动安装好了，具体命令：sudo apt-get install build-essential ****@****:~$ apt-cache depends build-essential build-essential |Depends: libc6-dev Depends: libc6-dev Depends: gcc Depends: g++ Depends: make make:i386 Depends: dpkg-dev Conflicts: build-essential:i386

lvm硬盘的挂载

原虚拟机硬盘是逻辑卷lvm，启用新虚拟机后需要把原硬盘数据迁移过来，可以scp，但是有效率问题和权限问题，于是考虑直接挂载。 1.在新虚拟机添加原有虚拟机硬盘 2.新虚拟机未使用lvm所以默认没有装lvm2工具，使用sudo apt-get install lvm2安装（原虚拟机使用lvm于是默认安装lvm2工具 3.使用pvs或pvdisplay查看物理卷，使用vgs查看卷组，使用lvdisplay查看逻辑卷，其中逻辑卷状态为not available，/dev/下没有相关设备，于是使用sudo vgchange -ay /dev/ubuntu-vg激活，一次性激活了ubuntu-vg中的两个分区：root和swap_1 4.挂载：sudo mount /dev/ubuntu-vg/root /mnt 进入查看，文件属性都没变，所属用户名也没变，所有信息完全一样。

关于局域网、网卡的几个小问题

1. 两台机在同一局域网内，通过一台交换机连出去，其中一台还通过了一台家庭路由器，两台之间隔很长时间才能通一次，远程连过去之后过会就卡一阵，而在外网的VPN连过来两台机都顺畅，说明局域网这两台机之间的设备没有很及时的把数据包转发给另一台机。

2. 笔记本电池耗尽突然down机，开机后不能上网，没有显示无线网络，删除虚拟网卡之后，显示绿色一格一格信号上有个红叉，这种一般是笔记本网卡硬件开关没打开，打开之后还是不行，最后设备管理器里面删除设备及驱动，自动安装（可能是win7从自己备份的地方复制过来）驱动后OK
