= GridFTP server installation =
* It is recommended to take the gridFTP server from the IGE (Initiative for Globus in Europe) repository.
Please configure IGE repositories. Example configuration for **SL5**:
{{{#!sh
cat > /etc/yum.repos.d/IGE.repo << EOF
[IGE]
name=IGE
baseurl=http://repo-rpm.ige-project.eu/sl/sl5/x86_64/
enabled=1
gpgcheck=1
gpgkey=http://repo-rpm.ige-project.eu/RPM-GPG-KEY-IGE
EOF
}}}

{{{#!sh
cat > /etc/yum.repos.d/IGE-updates.repo << EOF
[IGE-updates]
name=IGE - Updates
baseurl=http://repo-rpm.ige-project.eu/sl/updates/sl5/x86_64/
enabled=1
gpgcheck=1
gpgkey=http://repo-rpm.ige-project.eu/RPM-GPG-KEY-IGE
EOF
}}}

'''IMPORTANT:''' If for any reason you do not want to use IGE repos, you can alternatively configure the system to use EPEL (Extra Packages for Enterprise Linux) repository.
* The configuration can be done by installation of yum-conf-epel.noarch package using the YUM Package Manager.
{{{
#!div style="font-size: 90%"
{{{#!sh
yum install yum-conf-epel.noarch
}}}
}}}

 * Install the gridFTP server package:
{{{
#!div style="font-size: 90%"
{{{#!sh
yum install globus-gridftp-server-progs.x86_64
}}}
}}}


The grid-ftp server requires the X.509 certificate and key to be present in the following locations
    * ''/etc/grid-security/hostcert.pem''
    * ''/etc/grid-security/hostkey.pem''

The GridFTP server has to be configured to know the range of opened ports for connections.
Please edit (create) the /etc/xinetd.d/gsiftp file and set the GLOBUS_TCP_PORT_RANGE environment variable.

{{{#!sh
service gsiftp
{
 instances               = 100
 per_source              = 50
 socket_type             = stream
 wait                    = no
 user                    = root
 env                     += GLOBUS_TCP_PORT_RANGE=20000,25000
 server                  = /usr/sbin/globus-gridftp-server
 server_args             = -i  -l /var/log/globus-gridftp.log -disable-usage-stats -d ERROR,WARN
 log_on_success          += DURATION
 nice                    = 10
 disable                 = no
}
}}}

If needed please install the xinetd tool first
{{{#!sh
yum install xinetd.x86_64
}}}

IMPORTANT: Do not forget to reload xinetd service.

{{{#!default
/etc/init.d/xinetd reload
}}}

also check if its started on system boot by default:
{{{
/sbin/chkconfig --list xinetd
xinetd         	0:off	1:off	2:off	3:on	4:on	5:on	6:off
}}}

We also recommend to adjust system wide TCP keepalive parameters for reliability reasons:
{{{
echo "600" > /proc/sys/net/ipv4/tcp_keepalive_time
echo "75" > /proc/sys/net/ipv4/tcp_keepalive_intvl
echo "9" > /proc/sys/net/ipv4/tcp_keepalive_probes
}}}
In order to make the changes persistent add it also to the `/etc/sysctl.conf`
 * finally simply verify the installation by issuing the following command (if posible using external client host)
{{{
telnet grass1.man.poznan.pl 2811
Trying 150.254.173.215...
Connected to grass1.man.poznan.pl (150.254.173.215).

220 grass1.man.poznan.pl GridFTP Server 6.19 (gcc64, 1359994843-83) [Globus Toolkit 5.2.3] ready.
}}}
**Note:** Alternatively you can configure GridFTP in daemon mode (instead of using xinted):
{{{
# vim /etc/gridftp.conf
$GLOBUS_TCP_PORT_RANGE 20000,25000
port 2811
log_single /var/log/globus-gridftp.log
log_level ERROR,WARN

# chkconfig globus-gridftp-server on
# /etc/init.d/globus-gridftp-server start
}}}
