登入之後顯示如下：

1 [[email protected]_29_87_centos ~]# 

為root使用者，版本為centos ~是當前目錄/root。

然我們現在來分割槽：

當前沒有分割槽和格式化，無法用 df -h 命令看到資料盤

1 [[email protected]_29_87_centos ~]# df -h
2 Filesystem      Size  Used Avail Use% Mounted on
3 /dev/vda1        20G  1.1G   18G   6% /

然後輸入fdisk -l 檢視資料盤的資訊：

1 [
 
[email protected]_29_87_centos ~]# fdisk -l
2
3 Disk /dev/vda: 21.5 GB, 21474836480 bytes
4 255 heads, 63 sectors/track, 2610 cylinders
5 Units = cylinders of 16065 * 512 = 8225280 bytes
6 Sector size (logical/physical): 512 bytes / 512 bytes
7 I/O size (minimum/optimal): 512 bytes / 512 bytes
8 Disk identifier: 0x0007ee22
9 
10 Device Boot      Start         End      Blocks   Id  System
11 /dev/vda1   *           1        2611    20970496   83  Linux
 

上面顯示有一個21.5G的資料盤需要掛載分割槽

執行分割槽的操作如下：

1 fdisk /dev/vda

1 [[email protected]_29_87_centos ~]# fdisk /dev/vdb
2
3 Unable to open /dev/vdb
4 [[email protected]_29_87_centos ~]# fdisk /dev/vda
5
6 WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
7         switch off the mode (command 'c') and change display units to
8         sectors (command 'u').
9
10 Command (m for help): m
11 Command action
12 a   toggle a bootable flag
13 b   edit bsd disklabel
14 c   toggle the dos compatibility flag
15 d   delete a partition
16 l   list known partition types
17 m   print this menu
18 n   add a new partition
19 o   create a new empty DOS partition table
20 p   print the partition table
21 q   quit without saving changes
22 s   create a new empty Sun disklabel
23 t   change a partition's system id
24 u   change display/entry units
25 v   verify the partition table
26 w   write table to disk and exit
27 x   extra functionality (experts only)
 

根據幫助命令可知，先輸入n新建分割槽，再輸入p新建擴充套件分割槽。之後按wq儲存退出。 
在輸入fdisk -l 就可以看到新分割槽已經建立完成

1 [[email protected]_29_87_centos ~]# fdisk -l
2
3 Disk /dev/vda: 21.5 GB, 21474836480 bytes
4 255 heads, 63 sectors/track, 2610 cylinders
5 Units = cylinders of 16065 * 512 = 8225280 bytes
6 Sector size (logical/physical): 512 bytes / 512 bytes
7 I/O size (minimum/optimal): 512 bytes / 512 bytes
8 Disk identifier: 0x0007ee22
9 
10   Device Boot      Start         End      Blocks   Id  System
11 /dev/vda1   *           1        2611    20970496   83  Linux

之後需要對分割槽進行格式化，檔案系統可自行絕對（ext3,ext2）建議使用ext3 
使用如下的命令進行格式化分割槽。

1 [email protected]_29_87_centos ~]# mkfs.ext3 /dev/vda1
2 mke2fs 1.41.12 (17-May-2010)
3 /dev/vda1 is mounted; will not make a filesystem here!

顯示 已掛載 無法分割槽 
所以要先解除安裝分割槽再重新格式化

1 [[email protected]_29_87_centos ~]# umount /dev/vda1
2 umount: /: device is busy.
3        (In some cases useful info about processes that use
4         the device is found by lsof(8) or fuser(1))

顯示有程式使用/掛在該目錄上，我們剛分的區，哪裡來的程式？如何釋放該程式呢？ 
使用fuser - identify processes using files or sockets

1 [[email protected]_29_87_centos ~]# fuser -m /dev/vda1
2 /dev/vda1:               1rce     2rc     3rc     4rc     5rc     6rc     7rc     8rc     9rc    10rc    11rc    12rc    13rc    14rc    15rc    16rc    17rc    18rc    19rc    20rc    21rc    22rc    23rc    24rc    25rc    26rc    27rc    28rc    29rc    30rc    32rc    33rc    34rc    35rc    36rc    37rc    44rc    46rc    47rc    48rc    80rc    81rc   184rc   186rc   210rc   335rc   423rce   464rc   594rc   615rc   746rc   749re   950rce   972rce   994rce  1032rce  1075rce  1167rce  1183rce  1187rce  1204rce  1244rce  1246rce  1248rce  1250rce  1252rce  1253rce  1254rce  1256rce  3125rce  3129rce  3189rce

重複之前的動作，分個vda2出來

1 [[email protected]_29_87_centos ~]# fdisk /dev/vda
2
3 WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
4         switch off the mode (command 'c') and change display units to
5         sectors (command 'u').

配tomcat環境

先安裝nginx

一句程式碼

1 yum install nginx

再啟動nginx服務。

1 [[email protected]_29_87_centos ~]# service nginx start

檢驗nginx服務

1 [[email protected]_29_87_centos ~]# service nginx start
2 Starting nginx:                                            [  OK  ]
3 [[email protected]_29_87_centos ~]# sudo wget http://127.0.0.1
4 --2016-07-25 12:05:32--  http://127.0.0.1/
5 Connecting to 127.0.0.1:80... connected.

畢竟是搞android的nginx用到的不多，所以php環境還是配置了。。。
安裝： yum install php php-fpm 
啟動：service php-fpm start 一句strat php的service 
現在寫如何配jdk和tomcat
輸入 java -version 
看是否有自帶的openjdk版本

1 [[email protected]_29_87_centos ~]# java -version
2 java version "1.7.0_95"
3 OpenJDK Runtime Environment (rhel-2.6.4.0.el6_7-x86_64 u95-b00)
4 OpenJDK 64-Bit Server VM (build 24.95-b01, mixed mode)

有的話就不用管，有人說要換成oracle的jdk 我看了下其實這兩個差別不大，只是一個支援java8 一個不支援罷了 作為伺服器我們java用的很少 主要是用tomcat 我們現在來看如何配tomcat 
在http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html 下載你要的tomcat的版本 
然後用Filezila上傳到linux伺服器： 
再講tomcat移動到 /usr/local/

1 
2 [[email protected]_29_87_centos tomcat]# mv apache-tomcat-6.0.30/ /usr/local/

再在tomcat目錄下執行如下操作：開啟tomcat

1 [[email protected]_29_87_centos tomcat]#  /usr/local/tomcat/bin/catalina.sh start

即可在外部的瀏覽器中輸入ip地址和埠號看到tomcat貓了：

1 http://115.159.107.159:8080/

把index.html移動到webapps裡面之後。還是無法訪問。而且在分割槽的時候，不小心動了分割槽表然後出現grup錯誤。一直未能修復
