For those who looking for way to backup mysql database,
you can use mysqldump to backup mysql database.
Below is the script example to backup mysql database in command line:-
$ mysqldump -h localhost -u username -p database_name > backup_db.sql
If your mysql database is very big, you might want to compress your sql file.
Just use the mysql backup command below and pipe the output to gzip,
then you will get the output as gzip file.
$ mysqldump -u username -h localhost -p database_name | gzip -9 > backup_db.sql.gzIf you want to extract the .gz file, use the command below:-
$ gunzip backup_db.sql.gz
Apa itu VPN?

All multicast addresses can easily be recognized because they start with the bit pattern “1110″.
224.0.0.0 - 224.0.0.255 <em> Well-known multicast addresses, control channels</em> 224.0.1.0 - 238.255.255.255 <em> Globally-scoped (Internet-wide) multicast addresses</em> 239.0.0.0 - 239.255.255.255 <em> Local multicast addresses</em>
Private address ranges are not routed on the Internet and can be freely allocated in any private network. NAT (network address translation) is required when connecting such a network to the Internet.
Private network addresses (RFC1597/RFC1918 addresses):
10.0.0.0 - 10.255.255.255 <em>A 24-bit block, /8, class A network</em> 172.16.0.0 - 172.31.255.255 <em>A 20-bit block, /12, set of 16 contiguous class B network numbers</em> 192.168.0.0 - 192.168.255.255 <em>A 16-bit block, /16, set of 255 contiguous class C network numbers</em>
Special addresses:
127.0.0.0 – 127.255.255.255 Special address range for the localhost. You can normally not use those addresses for anything else. 127.0.0.1 is generally assigned to the loopback device
0.0.0.0 Special host address commonly reserved for the default route

Adalah program bantu untuk membangun dan menginstal modul-modul tambahan untuk apache HTTP server. Apxs melakukannya dengan membangun Dynamic Shared Object (DSO) dari satu sumber atau lebih sehingga dapat dimuatkan pada Apache server lewat paramater LoadModule dari modul mod_so (lihat bagian modul Apache yang telah dibahas sebelumnya). Misalnya untuk menambahkan modul foo (mod_foo.c), cukup ketikkan :
$ apxs -i -a -c mod_foo.c
Pilihan -i berarti menginstal, -a adalah otomatis menjalankan modul, -c berarti kompilasi pada saat instalasi. Untuk pilihan-pilihannya secara lengkap, tersedia dalam manual apxs.
$ man apxs

All user account related information is stored in /etc/passwd, /etc/shadow and /etc/group files to store user information. More…
