How to setup linux samba

Objective:

To setup a Linux file server using Samba on Centos 5.4

Actions Taken:
I. Installed the following:
    - samba-common-3.0.33-3.14.el5
    - samba-3.0.33-3.14.el5
    - system-config-samba-1.2.41-5.el5
    - samba-client-3.0.33-3.14.el5

II. Add current linux users to samba users (example: user fpg must exist in /etc/passwd):

# smbpasswd -a fpg yourpassword

III. Here's a sample /etc/samba/smb.conf:

[global]
        workgroup = MYGROUP
        netbios name = MEDIAS
        server string = Samba Server Version %v
        security = SHARE
        passdb backend = tdbsam
        log file = /var/log/samba/log.%m
        max log size = 50
        hosts allow = 127., 192.168.8., 192.168.10.

[Media]
        comment = Music and Video Collections
        path = /mnt/MEDIA
        read only = No
        guest ok = Yes

Notes:

In the [global] section, the interfaces option will serve workstations that belongs 192.168.8 and 192.168.10 block.

Windows 95/98/ME/NT4/2000 clients must logon to the samba server using their samba username when Windows starts up.

IV. Restart Samba:

# /etc/rc.d/init.d/smb restart

Oracle Installation Guide - Ivan-kartik

Installation of Oracle 9i (R2) on Fedora Core Linux 2, 3, 4, 5 and 6

This paper (HOWTO) describes step-by-step installation of Oracle 9i database software on Fedora Core 2, 3, 4, 5 and 6.

This paper covers following steps:

Pre-Instalation Tasks

1. Create oracle User Account

Login as root and create te user oracle which belongs to dba group.

su -
# groupadd dba
# useradd -g dba oracle

2. Setting System parameters
Edit the /etc/sysctl.conf and add following lines:

kernel.sem = 250 32000 100 128
kernel.shmmax = 2147483648
kernel.shmmni = 128
kernel.shmall = 2097152
kernel.msgmnb = 65536
kernel.msgmni = 2878
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000

Note: You need execute "sysctl -p" or reboot system to apply above settings.

Edit the /etc/security/limits.conf file and add following lines:

* - nproc 16384
* - nofile 16384

3. Setting Oracle Enviroment
Edit the /home/oracle/.bash_profile file and add following lines:

Settings for Fedora Core 2,3,4 only. For Fedora Core 5 and 6 use the next settings.

ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACLE_BASE/920
ORACLE_SID=MY_ORACLE
LD_LIBRARY_PATH=$ORACLE_HOME/lib
LD_ASSUME_KERNEL=2.4.1
THREADS_FLAG=native
ORACLE_OEM_JAVARUNTIME=/opt/jre1.3.1_15
PATH=$PATH:$ORACLE_HOME/bin

export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH LD_ASSUME_KERNEL THREADS_FLAG ORACLE_OEM_JAVARUNTIME PATH

Settings for Fedora Core 5 and 6 only. For Fedora Core 2,3,4 use the above settings. Note setting of LD_ASSUME_KERNEL will cause incorrect functionality of FC5 and FC6.

ORACLE_BASE=/opt/oracle
ORACLE_HOME=$ORACLE_BASE/920
ORACLE_SID=MY_ORACLE
LD_LIBRARY_PATH=$ORACLE_HOME/lib
ORACLE_OEM_JAVARUNTIME=/opt/jre1.3.1_15
PATH=$PATH:$ORACLE_HOME/bin

export ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH ORACLE_OEM_JAVARUNTIME PATH

Save the .bash_profile and execute following commands for load new enviroment:

cd /home/oracle
. .bash_profile

4. Create base directory for Oracle

Login as root and create base directory for Oracle ($ORACLE_BASE).

su -
# cd /opt
# mkdir oracle
# chown oracle:dba oracle

Download & Install

1. Download and install required .rpm packages

Some additional packages are required for succesful instalation of Oracle software. To check whether required packages are installed on your operating system use following command:

rpm -q gcc glibc-headers glibc-kernheaders glibc-devel compat-libstdc++ cpp compat-gcc

Note: You don't need glibc-kernheaders installed on FC6 as this package is not shipped with FC6.
If some package is not installed download it from Fedora project website or direct from Core 2, Core 3, Core 4, Core 5, Core 6 locations.

This step is required for Fedora Core 3 and 4 only. Fedora Core 3 is shipped with compat-gcc-8.3.3.4. Fedora Core 4 is shipped with compat-gcc-32-3.2.3. These package are GCC 3.x compiler which are not useful for succesful inatallation. Check whether compat-gcc-8.3.3.4 or compat-gcc-32-3.2.3 is installed. If so then uninstall it using folowing command:

rpm -e compat-gcc

Download the compat-gcc-7.3-2.96.126.i386.rpm package from Core 2 location or from here.

Install the required packages using the rpm command (Note version of packages may change in newer release, so versions for all packages (except compat-gcc package) used in next command are just for example.):

# rpm -ivh gcc-3.4.2-6.fc3.i386.rpm \
glibc-headers-2.3.3-74.i386.rpm \
glibc-kernheaders-2.4-9.1.87.i386.rpm \
glibc-devel-2.3.3-74.i386.rpm \
compat-libstdc++-3.4.2-6.fc3.i386.rpm \
cpp-3.4.2-6.fc3.i386.rpm \
compat-gcc-7.3-2.96.126.i386.rpm

For Fedora Core 4, 5 and 6 only:Install the required additional packages using the rpm command:

# rpm -ivh compat-libgcc-296-2.96-___.rpm \
compat-libstdc++-33-3.2.3-___.rpm \
compat-libstdc++-296-2.96-___.rpm

If all required packages were installed succesfuly then login as root and switch the GCC3 compiler binary with GCC2 compiler binary as following:

su -
# cd /usr/bin
# mv ./gcc ./gcc3
# mv ./gcc296 ./gcc

2. Download the Java Runtime Enviroment (j2re-1_3_1_15-linux-i586.bin) from the Sun website. Keep in mind you need to download j2re1.3.1_11 or higher (Note: Install JRE 1.3.1_1x version only).

Login as root and make the the file executable and then execute it. When the JRE is exracted move the "jre1.3.1_15" di rectory to "/opt" directory.

# chmod +x j2re-1_3_1_15-linux-i586.bin
# ./j2re-1_3_1_15-linux-i586.bin

# mv jre1.3.1_15 /opt/

3. Download the Oracle 9i (9.2.0.4) software from Oracle website.
Extract the files using following command:

gunzip ship_9204_linux_disk1.cpio.gz
gunzip ship_9204_linux_disk2.cpio.gz
gunzip ship_9204_linux_disk3.cpio.gz

cpio -idmv < ship_9204_linux_disk1.cpio
cpio -idmv < ship_9204_linux_disk2.cpio
cpio -idmv < ship_9204_linux_disk3.cpio

When all archives were extracted you've got three directories Disk1, Disk2 and Disk3.
Edit the Disk1/install/linux/oraparam.ini and modify JRE_LOCATION variable and set path to our JRE installation from Step 2.

JRE_LOCATION=/opt/jre1.3.1_15

4. Start the Oracle software installation process.

Now the system is prepared for Oracle software installation. To start the installation process execute the following commands:

cd Disk1
./runInstaller

When network configuration assistant and database configuration assistant has failed during st artup then do following steps:

cd /opt/oracle/920
rm JRE
ln -s /opt/jre1.3.1_15 JRE
su -
# cd /opt/oracle/920/JRE/bin
# ln -s java jre
# cd i386/native_threads
# ln -s java jre

Post-Instalation Tasks

1. Switch back the GCC binaries

su -
# cd /usr/bin
# mv ./gcc ./gcc296
# mv ./gcc3 ./gcc

2. Change of JRE path in Oracle Universal Installer

Edit the $ORACLE_BASE/oui/oraparam.ini file and modify the value of JRE_LOCATION to /opt/jre1.3.1_15

3. (Optional) You may consider to use rlwrap for comfortable work with sqlplus. RPM package for Fedora Core (x86) distribution you can download here.

su -
# rpm -ivh rlwrap-0.24.fedora.i386.rpm
# exit
echo "alias sqlplus='rlwrap sqlplus'" >> /home/oracle/.bash_profile
. /home/oracle/.bash_profile

How to set up CRON

Cron A Linux process that performs background work, often at night) is set up by default on your RedHat system. So you don't have to do anything about it unless you would like to add some tasks to be performed on your system on a regular basis or change the time at which cron performs its duties.

Please note that some of the cron work might be essential for your system functioning properly over a long period of time. Among other things cron may:

*Rebuild the database of files which is used when you search for files with the locate command.

*Clean the /tmp directory.

*Rebuild the manual pages.
*Rotate" the log files, i.e. discard the oldest log files, rename the intermediate logs, and create new logs,
*Perform some other checkups, e.g. adding fonts that you recently copied to your system.

Therefore, it may not be the best idea to always switch your Linux machine off for the night--in such a case cron will never have a chance to do its job. If you do like switching off your computer for the night, you may want to adjust cron so it performs its duties at some other time.

To find out when cron wakes up to perform its duties, have a look at the file /etc/crontab, for example:

cat /etc/crontab

It may contain something like this:

# run-parts

01 * * * * root run-parts /etc/cron.hourly

02 4 * * * root run-parts /etc/cron.daily

22 4 * * 0 root run-parts /etc/cron.weekly

42 4 1 * * root run-parts /etc/cron.monthly

You can see that there are four categories of cron jobs: performed hourly, daily, weekly and monthly. You can modify those or add your own category. Here is how it works.

The columns in the entries show: minute (0-59), hour (0-23), day of month (1-31), month of year (1-12), day of week (0-6--Sunday to Saturday). The "*" means "any valid value".

Thus, in the example quoted, the hourly jobs are performed every time the computer clock shows "and one minute", which happens every hour, at one minute past the hour. The daily jobs are performed every time the clock shows 2 minutes past 4 o'clock, which happens once a day. The weekly jobs are performed at 22 minutes past four o'clock in the morning on Sundays. The monthly jobs are performed 42 minutes past four o'clock on the first day of every month. The directory with the script file that contain the command(s) to be executed is shown as the last entry on each line.

If you wanted your jobs to be performed at noon instead of 4 in the morning, just change the 4s to 12s. Cron wakes up every minute and examines if the /etc/crontab has changed so there is no need to re-start anything after you make your changes.

If you wanted to add a job to your cron, place a script which runs your job (or a link to your script) in the directory /etc/cron.hourly or cron.daily or /etc/cron.weekly, or /etc/cron.monthly .

Here is an example of an entry in /etc/crontab which causes a job to be performed three times a week (Mon, Wed, Fri):

02 4 * * 1,3,5 root run-parts/etc/cron.weekly

An example seen on usenet showing how to automatically email a log file (edited for space):
