chmod = change file modes

After chmoding a file you can use ls -l to view the permissions.

Using the above chart you can combine permissions.

chmod 644 = rw-r–r–

chmod 731 = rwx-wx–x

Owner = user that created the file

Group = users in the same group as owner

Others = the rest of the users on the system

TAR is the Unix Tape ARchive utility. It can be used to either store data on a streaming tape device like a DAT drive, or store files in what is commonly called a tarball file- somewhat like a pkzip file, only compression is optional.
Source

[The basics]

In these examples, I will use the following file structure: a top level directory called DIR1 containing the files picture.jpg, document.doc and database.db.

DIR1/

DIR1/picture.jpg
DIR1/document.doc
DIR1/database.db

[Creating a tarball]

If we were in the directory DIR1 and wanted to backup all the files to a tarball called backup.tar, we could issue this command:

$ tar cvf backup.tar .

./
picture.jpg
doucment.doc
database.db
tar: backup.tar is the archive; not dumped

Note:
c=create (an archive)
v=verbose (just because)
f=filename (the name of our tarball)
.=current directory (what’s going to be backed up)

Also worth mentioning is that by default tar is recursive- meaning it will back up all files and subdirectories recursively unless you otherwise specify with the n flag (non-recursive)

[Displaying the Contents of a Tarball]

The current directory will now contain a file called backup.tar. To display the contents of the tarball file, we could issue this command:

$ tar tvf backup.tar

drwxr-xr-x root/gci 0 Jun 29 10:10 ./
-rw-r–r– root/gci 1 Jun 29 10:10 picture.jpg
-rw-r–r– root/gci 1 Jun 29 10:10 document.doc
-rw-r–r– root/gci 1 Jun 29 10:10 databse.db

Note:
t=table of contents (list)
v=verbose (display all info)
f=filename (backup.tar)

[Extracting Data from a Tarball]

To extract the entire contents of the tarball to the current directory, we can type:

$ tar xvf backup.tar

./
picture.jpg
doucment.doc
database.db

Note:
x=extract
v=verbose
f=filename (backup.tar)

To extract only the picture.jpg file from the archive, type the following command:

$ tar xvf backup.tar picture.jpg

Alternatively, you can use wild cards in either the creation or extraction of a tarball. To extract all jpg files from our archive, we can use a command like this:

$ tar xvf backup.tar *.jpg

[Using Compression]

If you would also like to add compression to your tarballs, you can combine the gzip utility with tar on the command line by adding the z switch to the command. Usually when this is done, we change the suffix of our tarball filename from .tar to either .tgz or .tar.gz. This will let whoever sees the file know that it is a gzipped tarball.

$ tar zcvf tarball.tgz .

Note:
z=gzip compression
c=create
v=verbose
f=filename (backup.tgz)
.=current directory (what to backup)

[Permissions with tar]

If you would like to preserve the permissions of the files you backup, use the p option with the tar command. This will save the uid, gid as well as the specific permission attributes of the files (read, write, execute etc.)

$ tar pzcvf tarball.tgz .

You should also use the p option with the tar extraction command:

$ tar pxvf tarball.tgz .

[Using tar with a Tape Drive]

I use tar in conjunction with my Seagate DAT drive. If you issue any of the previous commands in this HOW-TO without the f option and a tarball filename, you will find that tar will default to writing the files to the device /dev/rsa0 (raw sequential access device 0). Basically this is your first SCSI tape drive. If you have more than one tape drive you would like to use, you can issue the f option and the device name (rsa0, rsa1 etc.) of your specific tape drive instead of a filename.

Examples:
Backing up the current directory to Tape:

$ tar cv . <- default tape drive (rsa0)

$ tar cvf /dev/rsa1 . <- second tape drive (rsa1)

Restore files from Tape:

$ tar xv .
$ tar xvf /dev/rsa1

So, there are the basics of tar. If you would like more information on the tar command, try the man pages.

man tar

WWW: http://www.phpmyadmin.net/

push# cd /usr/ports/databases/phpmyadmin
push# make all install clean

phpMyAdmin-suphp-3.3.8.1 has been installed into:

/usr/local/www/phpMyAdmin

Please edit config.inc.php to suit your needs.

To make phpMyAdmin available through your web site, I suggest
that you add something like the following to httpd.conf:

Alias /phpmyadmin/ “/usr/local/www/phpMyAdmin/”

<Directory “/usr/local/www/phpMyAdmin/”>
Options none
AllowOverride Limit

Order Deny,Allow
Deny from all
Allow from 127.0.0.1 .example.com
</Directory>

Edit httpd.conf sesuai petunjuk di atas ( sesuaikan perijinan di buka dari mana aja, kalo mau di akses dari umum set ke Allow from all ) :
push# vi /usr/local/etc/apache22/httpd.conf
Restart apache-nya :
push# apachectl restart

Then…. buka browser dan ketikkan http://xxx.xxx.xxx.xxx/phpmyadmin/

Done…!!!

Langsung lagi…. buat menuhin catetan ye….

push#cd /usr/ports/lang/php52
push# make config
pilih option :
[X] CLI Build CLI version
[X] CGI Build CGI version
[X] APACHE Build Apache module
[X] SUHOSIN Enable Suhosin protection system (not for jails)
[X] MAILHEAD Enable mail header patch
[X] FASTCGI Enable fastcgi support (CGI only)
[X] PATHINFO Enable path-info-check support (CGI only)

setelah itu langsung lakukan perintah ini :
push# make all install clean
Setelah kelar edit file httpd.conf dan masukkan 2 baris di bawah :
push# vi /usr/local/etc/apache22/httpd.conf
#### TAMBAHAN UNTUK PHP ####
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
#### END ####
dan tambahkan pula index.php pada httpd.conf

DirectoryIndex index.html index.php

lalu save, kelar dah untuk masalah di apache-nya, sekarang lanjut lagi…
Sekarang edit file php.ini di sini kita bisa mengatur setingan php-nya nah by default lakukan dengan cara ganti nama file-nya aja dan ini udah ada dari file bawaan pas instalasinya :

push# mv php.ini-dist php.ini
setelah itu kita restart apache-nya :
push# /usr/local/sbin/apachectl restart

Setelah itu semua sekarang kita coba test php-nya dengan cara :
push# echo ‘<?php phpinfo();?>’ >> /usr/local/www/apache22/data/test.php

setelah itu coba kita test langusng lewat browser :

http://ip-server-nya/test.php

kalo berhasil akan tampil seperti ini :
System FreeBSD push.idconnect.co.id 7.3-RELEASE-p4 FreeBSD 7.3-RELEASE-p4 #0: Thu Dec 2 00:47:25 UTC 2010 root@push.idconnect.co.id:/usr/obj/usr/src/sys/BhoMerT i386

Done…!!! kelar masalah apache, php dan mysql…

Langsung aja… kita install lewat port aja ya…

push# cd /usr/ports/ && make search name=mysql-server

Port:   mysql-server-5.1.53
Path:   /usr/ports/databases/mysql51-server
Info:   Multithreaded SQL database (server)
Maint:  ale@FreeBSD.org
B-deps: mysql-client-5.1.53
R-deps: mysql-client-5.1.53
WWW:    http://www.mysql.com/

push# cd /usr/ports/databases/mysql51-server
push# make all install clean

setelah terinstall create database :

push# /usr/local/bin/mysql_install_db
Installing MySQL system tables…
OK
Filling help tables…
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/local/bin/mysqladmin -u root password ‘new-password’
/usr/local/bin/mysqladmin -u root -h push.idconnect.co.id password ‘new-password’

Alternatively you can run:
/usr/local/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr/local ; /usr/local/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/local/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/local/bin/mysqlbug script!

Nah.. setelah itu ganti kepemilikan dan group-nya ke mysql :
push# chown -R mysql /var/db/mysql/
push# chgrp -R mysql /var/db/mysql/

Jalankan daemon mysql-nya:
push# cd /usr/local ; /usr/local/bin/mysqld_safe &
[1] 4443
push# 101204 03:30:43 mysqld_safe Logging to ‘/var/db/mysql/push.idconnect.co.id.err’.
101204 03:30:43 mysqld_safe Starting mysqld daemon with databases from /var/db/mysql

cek status-nya menggunakan perintah #ps -aux
mysql 4486 0.0 1.1 45804 22028 p0 I 3:30AM 0:00.13 /usr/local/libexec/mysqld –basedir=/usr/local –datadir=/var/db/mysql –user=mysql –log-error=/var/db/mysql/push.idconnect.co

Setelah itu set password-nya :
push# /usr/local/bin/mysqladmin -u root password inipassword
push# /usr/local/bin/mysqladmin -u root -h push.idconnect.co.id password inipassword

Agar mysql otomatis jalan pas server reboot gunakan perintah ini :
push# echo ‘mysql_enable=”YES”‘ >> /etc/rc.conf

Done…!!!
