 +===== Ctags =====
 +Install Ctags:
 +  * Download Ctags at link http://ctags.sourceforge.net/
 +  * Install <code bash>
 +tar xf ctags-5.8.tar.gz
 +cd ctags-5.8
 +./configure
 +make
 +make install
 +</code>
 +===== lxr =====
 +==== Install and config lxr with Ctags ====
 +Get lxr at link http://sourceforge.net/projects/lxr/
 +
 +=== Pre-requisites ===
 +Run below command to check packages missing:<code bash>
 +./genxref --checkonly
 +</code>
 +  * Install perl File:MMagic<code bash>
 +yum install perl-ExtUtils-MakeMaker
 +wget http://www.cpan.org/authors/id/K/KN/KNOK/File-MMagic-1.30.tar.gz
 +tar xf File-MMagic-1.30.tar.gz
 +cd File-MMagic-1.30
 +perl perl Makefile.PL
 +make & make install
 +</code>
 +  * Install perl Glimpse:<code bash>
 +yum install perl-Module-Build
 +yum install perl-Test-Pod
 +yum install perl-Test-Pod-Coverage
 +wget http://webglimpse.net/trial/glimpse-latest.tar.gz
 +tar xf glimpse-latest.tar.gz
 +cd glimpse-4.18.6/
 +./configure
 +make & make install
 +</code>
 +  * Install mod_perl for apache:<code bash>
 +yum install perl-ExtUtils-Embed
 +wget http://mirrors.digipower.vn/apache/perl/mod_perl-2.0.8.tar.gz

 +cd mod_perl-2.0.8
 +perl Makefile.PL MP_APXS=/usr/local/apache/bin/apxs
 +make & make install
 +</code>add config mod_perl to /usr/local/apache/conf/httpd.conf:<code>LoadModule perl_module modules/mod_perl.so</code>
 +  * Install mod_version:<code bash>
 +/usr/local/apache/bin/httpd -M | grep version
 +version_module (static)
 +Syntax OK
 +</code> => mode_version has been installed
 +=== Install and Config lxr ===
 +  - Install:<code bash>
 +mkdir -p /data/www/lxr
 +cp -R lxr-2.0.2/* /data/www/lxr
 +</code>
 +  - Run script configure lxr with defauld configuration and below changes:<code bash>
 +./scripts/configure-lxr.pl -vv
 +Configure for single/multiple trees? [S/m] > m
 +Server type? [dedicated/SHARED] > dedicated
 +--- Host name or IP? [//localhost] > http://searchcode.babies.vn
 +--- DB user name? [lxr] >
 +--- DB password ? [lxrpw] > xxxxx
 +--- Directory for glimpse databases? >/data/glimpsedirbase
 +Is your Apache version 2.4 or higher? [YES/no] > no
 +</code> And config for first tree:<code>
 +--- Caption in page header? (e.g. Project XYZZY displayed by LXR) > python
 +--- Short title for button? (e.g. XYZZY) > python
 +--- Tree identification in URL? (e.g. the-tree) > python
 +--- Source directory? (e.g. /home/myself/project-tree) > /data/code
 +--- Database name? > python
 +--- Version name?  > 2.7
 +*** Configure another tree? [YES/no] > no
 +</code>
 +  - prepare config and check<code bash>
 +cp custom.d/lxr.conf
 +./genxref --checkonly
 +</code>Output:<code>
 +[  OK  ]     Perl     version ... 5.10.1
 +[  OK  ]     ctags    version ... 5.8
 +Checked:    glimpse   version ... 4.18.5
