一、使用root用戶登錄Ubuntu
安裝完成如需使用root身份登錄，可打開終端輸入以下命令：
#設置root密碼
1 sudo passwd root
#切換到root用戶
1 sudo -s
#輸入：（注意空格）
1 sudo gedit /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf
#在彈出的編輯框裡輸入：
50-ubuntu.conf:
1 [SeatDefaults] 3 autologin-user=root 5 user-session=ubuntu 7 greeter-show-manual-login=true
#保存關閉，回到終端窗口，輸入：
1 sudo passwd root
#回車，並輸入兩次密碼
#重啟，按root用戶登錄，密碼為上一步設置的密碼
二、准備工作（root權限下）
輸入以下命令（不分先後），完成Ubuntu的初步配置。
1 apt-get install gfortran//安裝gfortran4.2編譯器及其依賴的全部軟件包； 2 3 apt-get install libx11-dev//安裝 libx11-dev軟件包及其依賴的全部軟件包； 4 5 apt-get install csh//安裝csh； 6 7 apt-get install tcsh//安裝tcsh； 8 9 apt-get install gmt//安裝gmt4.2及其相關的軟件包。
完成後輸入
‘chsh’然後輸入‘/bin/csh’，重啟，使用echo $SHELL驗證
准備工作
三、安裝GAMIT10.35
首先在/opt目錄（用於存放可選的應用程序）下建立GAMIT/GLOBK的安裝目錄，並將安裝文件拷貝釋放到該目錄下。
終端中輸入
1 Searching your system for X11 installation 2 3 Found these paths to X11 libs and includes on your system 4 5 X11LIBPATH: /usr/lib 6 7 X11INCPATH: /usr/include/X11 8 9 Are these correct for your system? 10 11 Continue? (y/n)
開始安裝
安裝進行到

打開
1 /opt/gamit_globk/libraries/Makefile.config
修改內容：
maxatm = 13
改為25，確認繼續直至安裝完成
四、.cshrc的配置
主文件夾中新建.cshrc文件，輸入如下配置信息
1 # set prompt
2
3 set prompt = "[`echo $cwd`]% "
4
5 set history = 50
6
7 #set system path
8
9 set path = (. /bin /sbin /etc /usr/bin /usr/sbin /usr/bin/X11 /usr/X11R6/bin $path)
10
11 set path = (. /usr/local/bin /usr/local/sbin /usr/local/lib /usr/lib $path)
12
13 setenv PATH "/usr/sbin:/sbin:${PATH}"
14
15 setenv MANPATH /usr/local/man:/usr/X11R6/man
16
17 setenv LIBPATH /usr/lib:/usr/local/lib
18
19 #set Gamit/Globk path
20
21 set gamitpath = /opt/gamit_globk
22
23 set path = (. $gamitpath/gamit/bin $gamitpath/kf/bin $gamitpath/com $path)
24
25 setenv HELP_DIR $gamitpath/help/
26
27 #set GMT path
28
29 set gmtpath = /usr/lib/gmt/
30
31 set path = (. $gmtpath/bin $gmtpath/include $gmtpath/lib $gmtpath/man $gmtpath/share $gmtpath/www $path)
32
33 set path = (. /etc/gmt /usr/include/gmt /usr/lib/gmt /usr/share/gmt /usr/share/doc/gmt $path)
34
35 setenv MANPATH $gmtpath/man
36
37 #set full domain for GAMIT shell-scripts used to transfer data (sh_get_nav, sh_get_rinex, sh_get_orbits, and sh_get_hfiles)
38
39 set host = `\hostname | \awk -F. '{print $1}'`
40
41 set dom = `\hostname | \awk -F. '{print $2}'`
42
43 if( $dom == '' ) then
44
45 alias hostname 'echo $host.mit.edu'
46
47 endif
48
49 # set alias
50
51 alias cd 'cd \!*; set prompt = "[`echo $cwd`]% "'
52
53 alias pwd 'echo $cwd'
54
55 alias ls 'ls --classify'
