[問題] CentOS7 和 win7 雙系統引導，先安裝的win7在硬盤的前60G空間，後安裝CentOS7在接下來的60G空間。
[解決] 需要在CentOS7的引導配置中添加對win7的引導。

vim /boot/grub2/grub.cfg

添加win7的引導

menuentry ‘windows 7’ {

set root=‘hd0, msdos1’

chainloader +1

}

需要注意的是set root=‘hd0, msdos1’可能需要調整，可能是set root=‘hd0, msdos0’，根據實際做調整。

[問題] bhyve/Centos7 添加一塊硬盤（塊設備）

[解答]

host 中創建一塊ZFS分區作爲Centos7的一塊硬盤
sudo zfs create -V16G -o volmode=dev zroot/AOSP
將ZFS分區分配給虛擬機Centos7， 這裏用irtio-blk實現
-s 3:5,virtio-blk,/dev/zvol/zroot/AOSP \    
guest 查看新添加的硬盤
lsblk 可以看到 /dev/vdd

創建分區

sudo fdisk /dev/vdd

t 選擇 83

對創建的分區進行格式化（創建XFS文件系統）

[harvis@centos7 ~]$ sudo mkfs.xfs /dev/vdd1

臨時掛載(mount)

sudo mount -t xfs /dev/vdd1 /AOSP

sudo chown -R harvis:harvis /AOSP/

長久掛載

This location, and the isos that were hosted here, are now deprecated.

virtio-win builds are now distributed in a new location with a new iso file
layout. A yum repo is also provided. More info here:

Links to the _new_ equivalent of the old stable/ and latest/ directories are
listed here:

If you need access to the old isos that were hosted here, there's a mirror at:

  https://fedorapeople.org/groups/virt/virtio-win/deprecated-isos/

Only use them if you need to maintain backwards compatability. No new isos
will be added here.

[問題] yum源設置
[解決]

cd /etc/yum.repos.d/

wget http://mirrors.163.com/.help/CentOS-Base-163.repo

yum check-update

yum update

注意不需要更改文件名，按步驟操作即可。後面兩步其實是把系統和軟件包都給更新了。直接把centos5.5升級到5.10了。

2. aliyun yum源的配置

參考：http://mirrors.aliyun.com/help/centos

3. 安裝glibc 2.11的步驟

參考：http://hi.baidu.com/life_to_you/item/64db6dce367486dbef183b07

4. yum命令安裝程序時，總是出現如下警告：

There are unfinished transactions remaining. You might consider running yum-complete-transaction first to finish them.

意思是有未完成的yum事務，建議先運行yum-complete-transaction命令清除。消除警告步驟如下：

# 安裝 yum-complete-transaction（這是一個能發現未完成或被中斷的yum事務的程序）
yum install yum-utils
# 清除yum緩存
yum clean all
# 運行 yum-complete-transaction，清理未完成事務
/usr/sbin/yum-complete-transaction --cleanup-only
運行上述命令需要root權限。yum 會把下載的軟件包和header存儲在cache中，而不會自動刪除。可用yum clean headers清除header，yum clean packages清除下載的rpm包，yum clean all全清

5. 編輯DNS服務器IP地址

# vi /etc/resolv.conf

nameserver 8.8.8.8 #google域名服務器
nameserver 8.8.4.4 #google域名服務器

6. 更改系統時間和日期

修改日期：
時間設定成2009年5月10日的命令如下：
#date -s 05/10/2009

修改時間：
將系統時間設定成上午10點18分0秒的命令如下。
#date -s 10:18:00

修改時區：
找到相應的時區文件 /usr/share/zoneinfo/Asia/Shanghai替換當前的/etc/localtime。
修改/etc/sysconfig/clock文件的內容爲：
ZONE=”Asia/Shanghai”
UTC=false
ARC=false

同步bios時間：
同步BIOS時鐘，強制把系統時間寫入CMOS，命令如下：
#clock -w

CentOS 6.5（32位）編譯安裝 subversion 1.6.11

neon-0.29.3.tar.gz
subversion-1.6.11.tar.bz2
subversion-deps-1.6.11.tar.bz2

2. 解壓到同一個目錄下面
tar xvf subversion-1.6.11.tar.bz2
tar xvf subversion-deps-1.6.11.tar.bz2
3. 將subversion-1.6.11/neon裏面的內容全部刪除掉，將neon-0.29.3.tar.gz解壓進去subversion-1.6.11/neon
tar xvf neon-0.29.3.tar.gz -C subversion-1.6.11/neon
這一步若不用neon-0.29.3.tar.gz替代subversion-1.6.11/neon編譯會報錯，

CentOS升級Python到2.7

CentOS 6.3上安裝的python版本是2.6，不能滿足我運行軟件的要求，所以對python進行升級。

Python的最新版本已經是3.3，但是Python3的兼容性可能還有一定的問題，所以還是升級到2.7較爲保險。Python 2.7也能夠滿足絕大多數的軟件需求了。

原以爲這也就是安裝個軟件的事兒，在我求穩搜索一下了之後發現，也並不是那麼單純簡單。

下載，解壓，編譯，安裝，這些都是常規操作了。據說系統自帶的舊版本python被嚴重依賴，所以不能卸載原Python，這裏選擇全新安裝。

tar -xvf Python-2.7.3.tgz

cd Python-2.7.3

./configure --prefix=/usr/local/python2.7

make

make install

安裝好後可以運行一下Python看看是否正常了

1	/usr/local/python2.7/bin/python2.7-V

其他的文章提到python都是在/usr/local/bin目錄裏的，但是我沒有找到，而是在/usr/local/python2.7/bin/裏。

接下來需要創建一個鏈接來使系統默認python變爲python2.7。

1	ln -fs /usr/local/python2.7/bin/python2.7 /usr/bin/python

運行python查看版本

python-V

進行更改後，yum果然無法運行了。修改/usr/bin/yum文件，將第一行的

1	#!/usr/bin/python

中的python改爲系統原有的python版本，我的如下：

1	#!/usr/bin/python2.6

到此完畢。

【問題】ImportError: No module named pysqlite2

【解答】

The module is called sqlite3. pysqlite2 was the module's name before it became part of the Python standard library.

You probably want to use this in your code:

import sqlite3

And the standard documentation is here: http://docs.python.org/library/sqlite3.html

edit: And just to cover all the bases:

The sqlite3 module also has a dbapi2 sub-member, but you don't need to use it directly. The sqlite3 module exposes all the dbapi2 members directly.

3. yum groupinstall -y   "Desktop"   "Desktop Platform"   "Desktop Platform Development"　 "Fonts" 　"General Purpose Desktop"　 "Graphical Administration Tools"　 "Graphics Creation Tools" 　"Input Methods" 　"X Window System" 　"Chinese Support [zh]"　"Internet Browser"
4. 安裝好了桌面環境的軟件，然後再修改一下系統的啓動級別爲 5

　　編輯/etc/inittab文件，修改啓級別爲5，如下圖，然後重新啓動就可以進入桌面環境了。因爲我這是遠程環境的，只是運用了命令行，可以使用VNC進行桌面環境的遠程。
5. 重啓的過程中，設置一下桌面環境的幾個參數就可以正常進入登陸界面了，謝謝。

[問題] 通過移動硬盤安裝 CentOS 系統
[解決]
一、下載七個 CentOS-5.6-i386-bin-***.iso 文件到移動硬盤 fat32 格式相應分區根目錄，並將第一個解壓，取其 isolinux 放置在這個根目錄。
（DVD的鏡像文件大於4G，fat32 格式磁盤不接受。）
二、下載grub文件夾到移動硬盤,將其中的 grldr 和 menu.lst 複製到移動硬盤同上分區根目錄。
三、修改menu.lst 文件，加上：
title CentOS Install
kernel /isolinux/vmlinuz
initrd /isolinux/initrd.img
boot
四、運行bootice.exe（這是個不錯的工具）將移動硬盤的主、分區引導記錄都設置爲 grub4dos*** 。
五、設置 bios 移動硬盤啓動。
六、開機進入 Grub 界面，選擇 CentOS Install 安裝。
安裝過程中注意grub要選擇安裝在固定硬盤上，有相應選項。

[問題] CENTOS 6.3上安裝kingsoft-office-9.1.0.4032-0.1.a10.i686.rpm

[解答]

1. 下載WPS的rpm安裝包

kingsoft-office-9.1.0.4032-0.1.a10.i686.rpm

2. 無依賴安裝

rpm -ivh kingsoft-office-9.1.0.4032-0.1.a10.i686.rpm --nodeps

注意以前安裝過WPS的, 要先卸載掉.

卸載命令: rpm -e xxxxx.rpm

3. 添加依賴庫文件到目錄/opt/kingsoft/wps-office/office6/

不建議將庫文件放到/usr/lib或者/lib裏面, 那樣做可能影響其它軟件的正常運行.

WPS依賴的庫, 放在它自己的庫目錄裏, 這樣就不會影響外面的世界了, 嘿嘿.

依賴的庫文件手工複製到這裏, 缺啥複製啥.

[問題] The repository located at mirrors.aliyun.com is not a trusted or secure host and is being ignored. If this repository is available via HTTPS it is recommended to use HTTPS instead, otherwise you may silence this warning and allow it anyways with '--trusted-host mirrors.aliyun.com'.

[解決] 新的pip要求源必須是https, mirrors.aliyun.com is not https

cat ~/.pip/pip.conf

[global]

index-url = http://mirrors.aliyun.com/pypi/simple/

trusted-host=mirrors.aliyun.com ## add this line fix https warning

[install]
