ลง webui utorrent ใน CENTOS 6.5

วิธีการลง webui ใน centos 6.5 เห็นมีปัญหากันเยอะเรื่อง libssl
วิธีการทำข้างล่างนี้ก้อปปี้เขามา แต่แก้ไขเรื่อง libssl แล้ว สามารถใช้ได้เพราะทดสอบแล้ว หุหุ
ลองไปทำกันดูเด้อ

It has been six years since I migrated to Linux (from windows) and never looked back. I used to use uTorrent on windows as my torrent client. It was small, light-weight and very user friendly. Frankly speaking in these six years of my linux voyage, I never found any alternative to that. Until recently I heard that utorrent is now available for linux. Keeping my hopes high, I gave it a try and it lived up to my expectations. As expected it is free but closed-source, with a little hope from the forums that it might become open-source in the future. But anyways, I am really thankful to the utorrent team for briniging out utorrent for linux.

A couple of things felt missing but still it is  better than the most, infact all! It is currently an alpha release of version 3.0 build, with only web-based GUI and 32bit release (requires 32bit libraries on x64 systems).

Here is a complete step by step installation guide:

Step 0: Pre-Requisites

According to the website:

System Requirements:

  • x86 Ubuntu 9.10+, Debian 5+, Fedora 12+
  • Linux kernel 2.6.13 or newer required

utserver binary requires glibc-2.11 or newer. Do check this before continuing. To check your version of glibc:

rpm -q glibc

(Note: If you have old libraries, or facing any library related error, I have a different guide for you HERE )

I am using a 32 bit Centos 6.2, but this guide should work with most linux distributions. If you are using a x64 distribution, you’ll need to install all the 32 bit libraries.

In case of a 32 bit distro, there are hardly any dependencies to be installed. They are installed by default even in the minimal installations. Here is the list of dependencies anyway:

  • glibc >= 2.11
  • libgcc
  • openssl
  • krb5-libs
  • libcom_err
  • zlib
  • keyutils-libs
  • libselinux

If you are using a 32 bit distro:

yum install glibc libgcc openssl krb5-libs libcom_err zlib keyutils-libs libselinux openssl098e.i686

If you are using a 64bit distro, install the 32bit libraries:

yum install glibc glibc.i[36]86 libgcc libgcc.i[36]86 openssl openssl.i[36]86 krb5-libs krb5-libs.i[36]86 libcom_err libcom_err.i[36]86 zlib zlib.i[36]86 keyutils-libs keyutils-libs.i[36]86 libselinux libselinux.i[36]86 openssl098e.i686

Step 1: Make basic directories

I will keep it in /opt (ofcourse you can keep it anywhere feasible)

mkdir /opt/utorrent
mkdir /opt/utorrent/conf
mkdir /opt/utorrent/data
mkdir /opt/utorrent/pid
mkdir /opt/utorrent/webui
mkdir /opt/utorrent/log

Step 2: Download µTorrent Server

At the time of this writing, µTorrent Server alpha (3.0 build 25053) was the latest available one. You can find the latest release here. Download the package to a tmp location, extract and then copy the required files:

wget -O /tmp/utorrent-server-3.0-25053.tar.gz http://download.utorrent.com/linux/utorrent-server-3.0-25053.tar.gz
tar –directory /tmp -xzf /tmp/utorrent-server-3.0-25053.tar.gz

cp /tmp/utorrent-server-v3_0/utserver /opt/utorrent/

cp /tmp/utorrent-server-v3_0/webui.zip /opt/utorrent/webui/

Step 3: Libraries check

Before proceeding further, it will be a good idea to locate any missing libraries.
Use ldd command to find out any missing library:

ldd -r /opt/utorrent/utserver

You might get the following error:

/opt/utorrent/utserver: error while loading shared libraries: libssl.so.0.9.8: cannot open shared object file: No such file or directory

or

/opt/utorrent/utserver: error while loading shared libraries: libcrypto.so.0.9.8: cannot open shared object file: No such file or directory

If openssl is installed properly, this might be because you have a newer version of the shared library. Creating a softlink should solve the problem.

First find out what version you have:

find  /*/lib /*lib  -type f -name “libssl.so.*”

find  /*/lib /*lib  -type f -name “libcrypto.so.*”

This will show you the library you have installed, for example in my case it showed me that I’ve libssl.so.1.0.0 and libcrypto.so.1.0.0 installed:

[root@localhost ~]# find  /*/lib /*lib  -type f -name “libssl.so.*”
/usr/lib/libssl.so.0.9.8e

[root@localhost ~]# find  /*/lib /*lib  -type f -name “libcrypto.so.*”
/usr/lib/libcrypto.so.0.9.8e

Now simply create a soft link from the one you have to the one required by utserver:

ln -s /usr/lib/libssl.so.0.9.8e /usr/lib/libssl.so.0.9.8

ln -s /usr/lib/libcrypto.so.0.9.8e /usr/lib/libcrypto.so.0.9.8

(ofcourse you can always install the correct version of openssl instead of doing this softlink trick)

If every thing is fine you should get output some what like this:

[root@his apps]$ ldd -r /opt/utorrent/utserver
/opt/utorrent/utserver: /usr/lib/libcrypto.so.0.9.8: no version information available (required by /opt/utorrent/utserver)
/opt/utorrent/utserver: /usr/lib/libssl.so.0.9.8: no version information available (required by /opt/utorrent/utserver)
linux-gate.so.1 =>  (0x0042c000)
libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0x00cb8000)
libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0x009dc000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00110000)
libm.so.6 => /lib/libm.so.6 (0x00800000)
librt.so.1 => /lib/librt.so.1 (0x001a2000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00465000)
libc.so.6 => /lib/libc.so.6 (0x001ab000)
/lib/ld-linux.so.2 (0x005a8000)
libgssapi_krb5.so.2 => /lib/libgssapi_krb5.so.2 (0x00c25000)
libkrb5.so.3 => /lib/libkrb5.so.3 (0x0033b000)
libcom_err.so.2 => /lib/libcom_err.so.2 (0x0012b000)
libk5crypto.so.3 => /lib/libk5crypto.so.3 (0x00622000)
libresolv.so.2 => /lib/libresolv.so.2 (0x00130000)
libdl.so.2 => /lib/libdl.so.2 (0x0045b000)
libz.so.1 => /lib/libz.so.1 (0x00767000)
libkrb5support.so.0 => /lib/libkrb5support.so.0 (0x004be000)
libkeyutils.so.1 => /lib/libkeyutils.so.1 (0x00991000)
libselinux.so.1 => /lib/libselinux.so.1 (0x0014a000)

(You can ignore the “no version information” warning). This shows every requirement is fulfilled and utorrent server can now run on this machine. Lets now do some final config tweaks.

Step 4: Create config file

In theory you can just run the utserver binary (like you did in the previous step), and utorrent server should be ready and useable. You don’t necessarily need a config file But it is always a good idea to have a config file in hand, it’ll make editing and experimenting with the configurations much easier and give you a lot more options to play with.

I wasn’t able to find a complete and comprehensive config file. Users are either not using config file or using it just for a couple of options.
I’ve created this config file from the documentation and added all the options I found. All the directives are explained in the comments and set to the default value.

Here it is (only dir_root is set to /opt/utorrent/data all other values are default):

#
# Your software running on your device can create the following files in this directory in order to request the following maintenance procedures.
#
#    If the file c.utmr is created in or moved into this directory,

#    so that there will be no restrictions on IP address.
#
#    If the file rcf.utmr is created in or moved into this directory,
#    the server will reload the configuration file. If you always use this method to request a configuration file reload,
#    you can safely change the value of this setting while the server is running.

#ut_webui_dir (string):
# Default value: “”. Directory where the web UI file archive webui.zip is stored,
# or which contains a webui subdirectory within which the unarchived web UI files are stored.
# It can be an absolute path or set relative to the current directory.

# Default value: “”. If defined,
# finish_cmd is a command that will be executed upon completion of each torrent.
# state_cmd is a command that will be executed when a torrent changes state.
# The command is run asynchronously as the same user that runs the server process.
#
#    The server permits substitutions in the command text as follows:
#
#    %F Name of downloaded data file (for single-file torrents)
#    %D directory where torrent data files are saved
#    %N torrent title
#    %S torrent state
#    %P previous state of torrent
#    %L label associated with torrent
#    %T tracker
#    %M status message
#    %I hex-encoded info-hash
#
#    State (%S) and previous state (%P) are integers that have the following values:
#
#    1 (error)
#    2 (checked)
#    3 (paused)
#    4 (super seeding)
#    5 (seeding)
#    6 (downloading)
#    7 (super seeding (forced))
#    8 (seeding (forced))
#    9 (downloading (forced))
#    10 (queued seed)
#    11 (finished)
#    12 (queued)
#    13 (stopped)
finish_cmd:
state_cmd:

Don’t worry most of the lines in the config are comments (only 34 directives in total). I recommend going through it once.

Copy-Paste this configuration into the file utserver.conf in /opt/utorrent/conf/ directory using your favourite text editor like vim or download it directly:

wget -O /opt/utorrent/conf/utserver.conf http://kxr.me/blog/uts/utserver.conf

Now you can start the utorrent server with the following command:

/opt/utorrent/utserver -settingspath “/opt/utorrent/webui/” -configfile “/opt/utorrent/conf/utserver.conf” -logfile “/opt/utorrent/log/ut.log” -pidfile “/opt/utorrent/pid/utserver.pid” -daemon

and stop it with:

 kill `cat /opt/utorrent/pid/utserver.pid`

That is not very convenient, so lets create a script to make things easier.

 #!/bin/sh

uts_bin=”/opt/utorrent/utserver”
pid_file=”/opt/utorrent/pid/utserver.pid”
settings_path=”/opt/utorrent/webui/”
config_file=”/opt/utorrent/conf/utserver.conf”
log_file=”/opt/utorrent/log/ut.log”

start(){

if [ -s “$pid_file” ]
then
kill -s 0 `cat $pid_file` > /dev/null 2>&1
if  [ “$?” == “0” ]
then
echo “Err: Utorrent seems to be running, PID `cat $pid_file`”
else
echo “Starting Utorrent Server..”
cd $settings_path;$uts_bin -settingspath $settings_path -configfile $config_file -logfile $log_file -pidfile $pid_file -daemon
fi
else
echo “Starting Utorrent Server..”
cd $settings_path;$uts_bin -settingspath $settings_path -configfile $config_file -logfile $log_file -pidfile $pid_file -daemon
fi
}
stop(){
if [ -s “$pid_file” ]
then
kill -s 0 `cat $pid_file` > /dev/null 2>&1
if  [ “$?” == “0” ]
then
echo “Stopping Utorrent Server..”
kill `cat $pid_file`
tail -f /dev/null –pid `cat $pid_file`
rm -f $pid_file
else
echo “Err: Utorrent seems to be stopped, PID file $pid_file not found or empty”
fi
else
echo “Err: Utorrent seems to be stopped, PID file $pid_file not found or empty”
fi
}
status(){
if [ -s “$pid_file” ]
then
kill -s 0 `cat $pid_file` > /dev/null 2>&1
if  [ “$?” == “0” ]
then
echo “Utorrent seems to be running, PID `cat $pid_file`”
else
echo “PID file present, but no process with PID `cat $pid_file` running”
fi
else
echo “Utorrent seems to be stopped, PID file $pid_file not found or empty”
fi
}

case “$1” in
start)
start
;;
stop)
stop
;;
reload)
stop
rm -vf $settings_path/settings.dat*
start
;;
status)
status
;;
*)
echo “Usage $0 {start|stop|reload|status}”
;;
esac

Create a file called utsctl in /opt/utorrent and copy-paste the code into it using your favourite editor or download it directly:

wget -O /opt/utorrent/utsctl http://kxr.me/blog/uts/utsctl

Once you have created this script file, lets make it executeable:

chmod +x /opt/utorrent/utsctl

And also make it easily accessible, so that we don’t have to type the whole path again and again:

ln -s /opt/utorrent/utsctl /usr/bin/utsctl

Now starting stoping and checking the status is as easy as this:

utsctl start

utsctl stop

utsctl status

Step 5: Start µTorrent Server

Lets now start the utorrent server:

utsctl start

It should output “server started – using locale en_US.UTF-8” and return back to bash prompt. (Optionally, you can add this command to rc.local to auto-start it at startup)

You should now be able to access the utorrent server gui on localhost:

http://localhost:8080/gui

or via the ipaddress/hostname if accessing from a remote computer:

http://1.2.3.4:8080/gui

(don’t forget to allow this port in the system’s iptable firewall and any other firewall in between)

Here is a screen-shot:

Playing with the configuration:

When you change a configuration in utserver.conf, just restarting the utserver daemon won’t update the changes in WebUI. You’ll have to remove the settings.dat files and then start the server again i.e,

utsctl stop
rm -f /opt/utorrent/webui/settings.dat*
utsctl start

I’ve added the “reload” option in the utsctl script that will do all these three things:

utsctl reload

Good Luck 🙂
