實作時間：2017年10月20日
VirtualBox5.1(Windows10上安裝虛擬機器)安裝Debian9.2
所安裝軟體版本如下。
Apache 2.4
MariaDB 10.1
Perl 5.24
Flex 2.6
glimpse 4.8
lxr2.2.1
安裝步驟
(1)安裝apache2
#sudo apt-get install apache2
#vi /etc/apache2/site-available/000-default.conf
編輯ServerName
#service apache2 start
#update-rc.d apache2 defaults
(2)安裝mysql
#sudo apt-get install mysql-server
#service mysqld start
#update-rc.d mysql defaults
修改mysql的root密碼，不允許root遠端登入，進行安全性設定
#mysql_secure_installation
(3)安裝所需要的套件
#sudo apt-get install ctags
#sudo apt-get install perl perl-modules //通常安裝系統時會一起已安裝
#sudo apt-get install build-essential //安裝C語言開發環境
#cpan App::cpanminus //需用到C語言開發環境編譯程式
#cpanm File::MMagic
#sudo apt-get install libapache2-mod-perl2
#sudo apt-get install libdbi-perl libdbd-mysql-perl //安裝mysql-server會一起安裝
(4)安裝編譯環境
#sudo apt-get install flex
(5)安裝glimpse
sudo apt-get install glimpse
glimpse與swish-e只要使用其中一個就好。
(6)設定LXR
#cp lxr-2.2.1.tgz /var/www/html
#cd /var/www/html
#tar -zxvf lxr-2.2.1.tgz
#mv lxr-2.2.1 lxr
#./scripts/configure-lxr.pl -vv
root@debian:/var/www/html/lxr# ./scripts/configure-lxr.pl -vv
*** LXR configurator (version: 2.2) ***
LXR root directory is /var/www/html/lxr
Configuration will be stored in custom.d/
directory custom.d created
directory custom.d/db-scripts.d created
Configure for single/multiple trees? [S/m] >
Do you intend to add other trees later? [yes/NO] >
*** LXR web server configuration ***
Many different configurations are possible, they are related to the way
LXR service is accessed, i.e. to the structure of the URL.
Refer to the User's Manual for a description of the variants.
LXR can be located at the server-root (so called dedicated)
or lower in the server hierarchy (shared because there are
usually other pages or sections).
Server type? [dedicated/SHARED] >
The computer hosting the server is described by an URL.
The form is scheme://host_name:port
where:
- scheme is either http or https (http: can be omitted),
- host_name can be given as an IP address such as 123.45.67.89
or a domain name like localhost or lxr.url.example,
- port may be omitted if standard for the scheme.
--- Host name or IP? [//localhost] >
--- Alias name or IP? > //192.168.43.73
--- Alias name or IP? >
URL section name for LXR in your server? [/lxr] >
*** LXR database configuration ***
The choice of the database engine can make a difference in indexing performance,
but resource consumption is also an important factor.
* For a small personal project, try SQLite which do not
need a server and is free from configuration burden.
* For medium to large projects, choice is between MySQL,
PostgreSQL and Oracle.
Oracle is not a free software, its interface has not been
tested for a long time.
* PostgreSQL databases are smaller than MySQL's
and performance is roughly equivalent.
* MySQL is at its best with large-sized projects
(such as kernel cross-referencing) where it is fastest at the cost
of bigger databases.
* Take also in consideration the number of connected users.
Database engine? [MYSQL/oracle/postgres/sqlite] >
--- Directory for glimpse databases? > /var/www/html/glimpse
file .htaccess written into LXR root directory
file apache2-require.pl written into configuration directory

file nginx-lxrserver.conf written into configuration directory
file thttpd-lxrserver.conf written into configuration directory

*** LXR master configuration file setup ***
Global section part
*** Configuring auxiliary tool paths
*** Host name previously defined as http://localhost
*** Configuring HTML parameters
*** 'Buttons-and-menus' interface is recommended for the kernel
*** to avoid screen cluttering.
--- Use 'buttons-and-menus' instead of 'link' interface? [YES/no] >
*** Configuring file subsection
*** Configuring "common factors"
*** Marking tree section
*** LXR master configuration file setup ***
Tree section part
SQL script for database initialisation
*** Configuring LXR server parameters
*** The virtual root is the fixed URL part after the hostname.
*** You previously defined the virtual root as /lxr
--- Caption in page header? (e.g. Project XYZZY displayed by LXR) > LXR
Do you need a specific encoding for this tree ? [yes/NO] >
*** Describing tree location
How is your tree stored? [FILES/cvs/git/svn/hg/bk] >
*** A source directory contains one sub-directory for every version.
--- Source directory? (e.g. /home/myself/project-tree) > /var/www/html
Name to display for the path root? (e.g. Project or $v for version) [$v] >
*** Enumerating versions
Label for version selection menu? [Version] >
*** Versions can be explicitly enumerated, be read from a file or computed
*** by a function. The latter case is recommended for VCS-stored trees.
Version enumeration method? [LIST/file/function] >
--- Version name? > slxr
--- Version name? (hit return to stop) >
*** By default, first version in list is displayed. You may also indicate
*** a prefered version.
--- Default displayed version is first in 'range'? [YES/no] >
*** Setting directory lists
*** Some directories may contain non-public project data (binaries,
*** compilers caches, SCM control data, ...). They can be hidden from LXR.
--- Directory to ignore, e.g. CVSROOT or CVS? (hit return to stop) >
*** If your source code uses "include" statements (#include, require, ...)
*** LXR needs hints to resolve the destination file.
--- Include directory, e.g. /include? (hit return to stop) >
*** Configuring data storage
--- Database name? > lxr
--- DB user name? [lxr] >
--- DB password? [lxrpw] > 資料庫使用者lxr的密碼
--- DB table prefix? [lxr_] >
configuration saved in custom.d/lxr.conf
DB initialisation script is custom.d/initdb.sh
(7)建立資料庫與資料庫使用者
執行「./custom.d/initdb.sh」建立資料庫與新增資料庫使用者lxr
若無法登入，請重新執行./scripts/configure-lxr.pl -vv，輸入正確mysql的使用者lxr密碼，重新產生initdb.sh再執行./custom.d/initdb.sh
(8)拷貝「lxr.conf」到lxr目錄
cp ./custom.d/lxr.conf /var/www/html/lxr
(9)使用ctags與glimpse產生索引
#./genxref --checkonly
可以忽略swish-e找不到的錯誤
#./genxref --url=http://192.168.43.73/lxr --versions=slxr //建立索引
http://192.168.43.73/lxr為LXR原始碼所在網址，slxr為Version Name，在剛剛設定的/var/www/html (source directory)的資料夾下，將要做交叉參照原始碼放在slxr資料夾下。
在 /var/www/html 下，將要建立索引的程式碼放置於slxr資料夾下，本範例放置LXR的原始碼。
以下為建立索引值螢幕顯示的畫面
root@debian:/var/www/html/lxr# ./genxref --url=http://192.168.43.73/lxr --versions=slxr
Unknown option: versions
[ OK ] Perl version ... 5.24.1

Checked: glimpseindex version ... 4.18.7
Parameter 'swishbin' not defined - trying to find swish-e

usage: /usr/bin/glimpseindex [-help] [-a] [-d] [-f] [-i] [-n [X]] [-o] [-r delim] [-s] [-t] [-w X] [-B] [-F] [-H DIR] [-I] [-M X] [-R] [-S X] [-T] [-V] NAMES
List of options (see http://webglimpse.net/ for more details):
-help: outputs this menu
-a: add given files/directories to an existing index
-b: build a (large) byte-level index
-B: use a hash table that is 4 times bigger (256k entries instead of 64K)
-d NAMES: delete (file or directory) NAMES from an existing index
-D NAMES: delete NAMES from the list of files (but not from the index!)
-E: do not run a check on file types
-f: incremental indexing (add all newly modified files)
-F: the list of files to index is obtained from standard input
-h: generates some hash-tables for WebGlimpse
-H DIR: the index is put in directory DIR
-i: make .glimpse_include take precedence over .glimpse_exclude
-I: output the list of files that would be indexed (but don't index)
-M X: use X MBytes of memory for temporary tables
-n [X]: index numbers as well as words; warn (into .glimpse_messages)
if file adds > X% numeric words: default is 50
-o: build a small (rather than tiny) size index (the recommended option!)
-r delim: build an index at the granularity of delimiter `delim'
to do booleans by reading ONLY the index
-R: recompute .glimpse_filenames_index from .glimpse_filenames if it changes
-s: build index to support structured (Harvest SOIF type) queries
-S X: adjust the size of the stop list
-t: sort the indexed files by date and time (most recent first)
-T: build .glimpse_turbo for very fast search with -i -w in glimpse
-U: there is extra information after filenames: works only with -F
-w X: warn (into .glimpse_messages) if a file adds >= X words to the index
-X: extract titles of all documents with .html, .htm, .shtm, .shtml suffix
-z: customizable filtering using .glimpse_filters
