Fedora User Manager

without comments

As one of my students pointed out, Fedora doesn’t install a GUI user management tool installed by default. That’s true. It’s easy to install. You can install it as the root user, like:

yum install -y system-config-users

It should generate a screen console output like this when successfully installed:

Loaded plugins: langpacks, refresh-packagekit
http://yum.postgresql.org/9.3/fedora/fedora-20-x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

Complete!

You can verify the GUI user management tool is present with the following command:

which system-config-users

It should return this:

/bin/system-config-users

You can run the GUI user management tool from the root user account or any sudoer account. The following shows how to launch the GUI User Manager from a sudoer account:

sudo system-config-users

It will generate the following GUI User Manager screen:

As always, I hope this helps those trying to do some that should be a basic task that seems to get lost form the books and manuals beginners use.

How to install MongoDB

without comments

This post shows the yum command to install the MongoDB packages on Linux. More on setup and use will follow.

You install the MongoDB package with the following yum command:

yum install -y mongodb

You should see the following log file, which may also show a missing mirrored site:

Can’t Display 256 Colors

without comments

If you’re reading this post, you most likely are trying to run the Oracle Database 11g or 12c runInstaller program, and it’s failing a critical dependency check and displaying an error like the one below. If so, choose n because if you choose y it won’t launch the Oracle Installer.

Starting Oracle Universal Installer...
 
Checking Temp space: must be greater than 500 MB.   Actual 30824 MB    Passed
Checking swap space: must be greater than 150 MB.   Actual 3967 MB    Passed
Checking monitor: must be configured to display at least 256 colors
    >>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set.    Failed <<<<
 
Some requirement checks failed. You must fulfill these requirements before
 
continuing with the installation,
 
Continue? (y/n) [n] n

The first thing to check is whether you’ve the $TERM environment variable. It’ll be set in your env list but may not be set in your .bashrc file. You can see whether it’s set by running the following command:

echo $TERM

It should return a value, like this:

xterm-256color

If you didn’t get that value, use the env command to lookup the $TERM. The correct value can be found by running the env command like this:

env | grep -i term

Add $TERM environment variable to your .bashrc file and source it after the change or reboot the user’s session:

export TERM=xterm-256color

If it still doesn’t work, some posts ask you to run xclock but you don’t generally install the xhost clients. Those articles assumes you’ve installed the xorg-x11-apps package library. That’s more or less a choice you made when installing the Linux OS. You can check for the presence of the library with the following command as the root user:

rpm -qa xorg-x11-apps

If the command fails to return a result from the search of Red Hat Package Manager (RPM) libraries, you haven’t installed it. You can install it as the root superuser with this syntax:

yum install -y xorg-x11-apps

It should display the following result when successful:

Oracle 12c Pre-requisites

without comments

Installing any Oracle database is tedious, but the installing the prerequisites can be especially tedious. This post tries to simplify the process by creating a single prereq.sh file for all the prerequisite libraries, except for the oracle-rdbms-server-12cR1-preinstall, which you should run after the prerequisite file.

The prerequisite file should contain the following:

yum install -y binutils \
               compat-libstdc++-33 \
               compat-libstdc++-33.i686 \
               gcc \
               gcc-c++ \
               glibc \
               glibc.i686 \
               glibc-devel \
               glibc-devel.i686 \
               ksh \
               libgcc \
               libgcc.i686 \
               libstdc++ \
               libstdc++.i686 \
               libstdc++-devel \
               libstdc++-devel.i686 \
               libaio \
               libaio.i686 \
               libaio-devel \
               libaio-devel.i686 \
               libXext \
               libXext.i686 \
               libXtst \
               libXtst.i686 \
               libX11 \
               libX11.i686 \
               libXau \
               libXau.i686 \
               libxcb \
               libxcb.i686 \
               libXi \
               libXi.i686 \
               make \
               sysstat \
               unixODBC \
               unixODBC-devel \
               zlib-devel \
               zlib-devel.i686

You can run the prereq.sh script as the root user like you would source an environment file:

. ./prereq.sh

Dependent upon what you installed when creating the Oracle Linux 7.1 operating system, you should see something like this in the output console:

sh-4.2# . ./prereq.sh

After running the oracle-dbms-server-12cR1-preinstall library, you can navigate through the Applications, Sundry, and Users and Groups to see the following dialog:

OracleUserCreated

It’s hard to tell from the GUI the oracle user’s group. You can find oracle primary user’s group by checking the /etc/passwd file. You will find that oinstall is the primary user’s group.

As always, I hope this helps those trying to install an Oracle Database 12c instance. Please post a comment if you have a better way to load the pre-requisite packages.

Fix VMware Networking

with 3 comments

Occasionally, my students loose their network connection when copying their virtual machines. This article shows you how to rebuild your Internet connection.

The first step requires you to identify the port number on your host operating system, which is typically Windows OS or Mac OS X. You can find that by running the following search from a Mac OS X Terminal session or Windows OS Command session.

If you’re on the Mac OS X, you launch a Terminal session and then use the sudo command to open a shell as the root super user, like this:

sudo sh

As the root super user on Mac OS X , you run the netstat command like this:

sh-3.2# netstat -a | grep 1.ntp | grep -v grep
udp4       0      0  192.168.147.1.ntp      *.*

VMware uses the same subdomain with one difference for the gateway, it uses node 2:

192.168.147.2

The alternate syntax to find Vmware’s subdomain requires you to use an Administrator account on Windows, like this:

C:\> netstat -a | findstr /C:.ntp

After you determine the subdomain, you need to ensure VMware is configured correctly. You navigate to the menu and choose Virtual Machine and then Settings from the dropdown menu. The software shows you the following:

Linux7Network1

Then, click on the Network Adapter under the Removable Devices, and you see the following screen:

Linux71Network2

You need to make sure that you’re using Internet Sharing, or Share with my Mac. If you’re not using it select it now.

Launch the hosted Linux OS and open a Terminal seesion. Inside the Terminal, you should find the machine’s address as the root address with the ifconfig utility. The technique follows:

[student@localhost ~]$ sudo sh
[sudo] password for student: 
sh-4.2# ifconfig
eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        ether 00:0c:29:70:77:64  txqueuelen 1000  (Ethernet)
        RX packets 34  bytes 4190 (4.0 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
 
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 0  (Local Loopback)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Next, you need to edit some files, they assume the VMware Network Gateway is 192.168.147.2 and the machine’s address is “00:0c:29:70:77:64“. The first file you need to edit is the /etc/resolv.conf file, and it should look like this:

domain localdomain
search localdomain
nameserver 192.168.147.2

The second file you need to edit is the /etc/sysconfig/network file. It should look like this:

# Created by anaconda
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.147.2

The third file you need to edit is the /etc/sysconfig/network-scripts/ifcfg-eth0 file. It should look like this:

DEVICE=eth0
HWADDR=00:0c:29:70:77:64
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
TYPE=Ethernet
DNS1=192.168.147.2
USERCTL=no
PEERDNS=yes
IPV6INIT=no

The last step requires that you reboot the machine or run the /etc/rc.d/init.d/network to restart the network. I hope this helps those trying to restore their VMware hosted operating systems network connection.

LAMP php-gd Libraries

with one comment

Everything seemed complete after configuring my standalone MySQL instance to a LAMP installation, but last night I started playing with the image files. It turns out that I failed to install the php-gd library.

There’s very little feedback when you try to troubleshoot why you can’t read an image. In fact, the error message for reading the BLOB from MySQL was only available on the local Firefox browser:

The image "http://localhost/ConvertMySQLBlobToImage.php" cannot be displayed because it contains errors.

The fix requires root to install the php-gd library with the yum utility:

yum install php-gd

You’ll need to answer y to one question during the installation:

Complete!

After the installation, you can run the info.php program, which contains the following:

1
2
3
<?php
  phpinfo();
?>

You’ll find the following gd library display in the result from the info.php program:

Linux_php_gd_library

After retesting, we get both large text and blob files displayed in the web page:

LAMPBlobTextPage

As always, I hope this helps others. Especially, those who are working with your LAMP stack implementation of images.
