Mysql

These are the rpms need to install mysql

[root@localhost ~]# rpm -qa |grep -i mysql
mysql-5.0.45-4.fc8
php-mysql-5.2.4-3
mysql-libs-5.0.45-4.fc8
mysql-server-5.0.45-4.fc8
perl-DBD-MySQL-4.005-2.fc8.1

There are 2 default account in mysql

1: root -- permits full access to mysql database
2: anonymous -- permits only access to test database


Note: 1: all the commnad in mysql ends with semicolon(;)
2: In its default state connection can only be made from localhost
3: Mysql security is not contigent upon OS security

2 ways to set root password

1: mysqladmin -u root password 'r00t'
2: set password for 'root'@'localhost'=password('abc123')


Removing anonymous user

mysql> delete from user where user=' ';

mysql> flush privileges; (To re-read the grant tables)

Creating swap partitions

How to create swap partitions

Step1: [root@localhost ~]# fdisk -l

Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders

The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:

Step8: Reboot the system

Step9: Creating the file system

[root@localhost ~]# mke2fs -j /dev/sda8 (If we dont give -j it will create ext2 based file system)
mke2fs 1.40.2 (12-Jul-2007)
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
26104 inodes, 104388 blocks
5219 blocks (5.00%) reserved for the super user
First data block=1
Maximum filesystem blocks=67371008
13 block groups
8192 blocks per group, 8192 fragments per group
2008 inodes per group
Superblock backups stored on blocks:
8193, 24577, 40961, 57345, 73729

Writing inode tables: done
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 35 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.


Step10: Temporarily mount the partition
[root@localhost ~]# mount /dev/sda8 /mnt


Step11: If we want permanent mounting or the mounting exist after reboot we need the entry in /etc/fstab

/dev/sda8 /mnt ext3 defaults 0 0

Step12:

[root@localhost ~]# mount
/dev/sda3 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda5 on /var type ext3 (rw)
/dev/sda2 on /usr type ext3 (rw)
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/sr0 on /media/Fedora 8 i386 DVD type iso9660 (ro,nosuid,nodev,uhelper=hal,uid=0)
/dev/sda7 on /media/disk type ext3 (rw,nosuid,nodev,uhelper=hal)
/dev/sda8 on /mnt type ext3 (rw) After that we see that mounted partitions

Step13: If we create a partitions having filesystem which is ext2 based we can convert it to ext3 by using following command

tune2fs -j /dev/sda8

Positional Parameters

A positional parameter is a parameter denoted by one or more digits, other than the single digit 0. Positional parameters are assigned from the shell's arguments when it is invoked

The shell maintains a variable called $# that contains the number of items on the command line in addition to the name of the command

For eg: If i write a simple program
#!/bin/bash
echo $#

and try to execute it

[root@localhost bash]# . test.sh # Since no variable is passed so output is 0
0

[root@localhost bash]# . test.sh 1 # Since 1 variable is passed so output is 1
1

[root@localhost bash]# . test.sh 2 # Since 1 variable is passed so output is 1
1

[root@localhost bash]# . test.sh 3 # Since 1 variable is passed so output is 1(independent of value if i passed 3 here the o/p is same 1)
1

[root@localhost bash]# . test.sh 2 5 #Sincei passed 2 variables(2and5)hence o/p is 2
2



The example script to determine positional parameters

#!/bin/bash
BADPARAM=165 # if no value is passed the output status is 165 (echo $?)
if [ $# != 2 ] # No of variables need to pass to script
then
echo "This script require at least 2 arguments"
echo "You have entered $# arguments"
exit $BADPARAM
fi
seq $1 $2

[root@localhost bash]# . posparam.sh 1 4

Summary : NFS utilities and supporting clients and daemons for the kernel NFS server
Description :
The nfs-utils package provides a daemon for the kernel NFS server and
related tools, which provides a much higher level of performance than the
traditional Linux NFS server used by most users.

This package also contains the showmount program. Showmount queries the
mount daemon on a remote host for information about the NFS (Network File
System) server on the remote host. For example, showmount can display the
clients which are mounted on that host.

This package also contains the mount.nfs and umount.nfs program.

Linux File System Permission

It is divided into 4 parts

class:owner:group:everyone/other


Maximum Possible Permission bit

read(r) 4
write(w) 2
execute(1) 1

For eg:

[root@localhost ~]# ls -l install.log
-rw-r--r-- 1 root root 37356 2008-07-27 02:26 install.log
-42-4--4--

So this file has a permission 644

Maximum permission to any file 666

Maximum permission to any directory 777

By default if we create any file it has permission 644

By default if we create any directory it has permission 755

This is due umask value

[root@localhost ~]# umask
0022

For file 666 - 022 = 644
For directory 777 - 022 = 755

chmod: Alter the permission of files and directories

[root@localhost ~]# ls -ld abc
drwxr-xr-x 2 root root 4096 2008-07-29 12:01 abc

If we want to change the permission of this directory from default 755 to other we need chmod command

[root@localhost ~]# chmod 777 abc
[root@localhost ~]# ls -ld abc
drwxrwxrwx 2 root root 4096 2008-07-29 12:01 abc
[root@localhost ~]#

If we want this permission applied to all the create file inside this directory

-R, --recursive change files and directories recursively

chown - change file owner and group

[root@localhost ~]# chown prashant:prashant abc
[root@localhost ~]# ls -ld abc
drwxrwxrwx 2 prashant prashant 4096 2008-07-29 12:01 abc

-R, --recursive operate on files and directories recursively

chgrp - change group ownership

[root@localhost ~]# chgrp prashant abc1
[root@localhost ~]# ls -ld abc1
drwxr-xr-x 2 root prashant 4096 2008-07-29 12:09 abc1

SETGID Permission

[root@localhost ~]# mkdir share
[root@localhost ~]# chown root:prashant share/
[root@localhost ~]# ls -ld share
drwxr-xr-x 2 root prashant 4096 2008-07-29 12:14 share
[root@localhost ~]# chmod 2775 share/

Here we are assiging set group ID (2) or we do it like this (chmod g+s share)

[root@localhost ~]# ls -ld share
drwxrwsr-x 2 root prashant 4096 2008-07-29 12:14 share
[root@localhost ~]# ls -ld share
drwxrwsr-x 2 root prashant 4096 2008-07-29 12:14 share
[root@localhost ~]# chmod 777 share/

After doing this if any user try to create any file it has got the group prashant associated with it

[oracle@localhost share]$ ls -l
-rw-r--r-- 1 oracle prashant 0 2008-07-29 12:16 b

Symbolic Link(Soft and Hard Link)

Soft Link

ln [--option] [actual file] [name of symbolic link]

[root@localhost bash]# ln -s file1 symlink1

lrwxrwxrwx 1 root root 5 2008-07-29 12:22 symlink1 -> file1

All the permission bit are turn on in case of symbolic link to drill down the file

Note: We can create multiple symbolic link to the same file.But if the main file is removed then symboli link has no meaning.

[root@localhost bash]# ln -s file1 symlink2

lrwxrwxrwx 1 root root 5 2008-07-29 12:24 symlink2 -> file1

Both the symbolic link created have different inode number

159984 lrwxrwxrwx 1 root root 5 2008-07-29 12:22 symlink1 -> file1
159990 lrwxrwxrwx 1 root root 5 2008-07-29 12:24 symlink2 -> file1

Inode number: File stored in disk have unique number called inode number

Hardlink:

ln [actual file] [hardlink]

[root@localhost bash]# ln file1 hardlink1

159965 -rw-r--r-- 2 root root 0 2008-07-29 12:22 hardlink1
159965 -rw-r--r-- 2 root root 0 2008-07-29 12:22 file1

Both have same inode number

If we delete orignal file hardlink file exist.

Redhat Package Manager(RPM)

RPM Characterstics:

1: Resolve the dependecy control
2: It provide compression
3: Provide metadata for the included application
4: Version Control


If we do which rpm

related tools, which provides a much higher level of performance than the
traditional Linux NFS server used by most users.

This package also contains the showmount program. Showmount queries the
mount daemon on a remote host for information about the NFS (Network File
System) server on the remote host. For example, showmount can display the
clients which are mounted on that host.

This package also contains the mount.nfs and umount.nfs program.
