Kemaren waktu baca-baca di forum.linux.or.id, ada yang tanya bagaimana caranya membuat repositori lokal di Zencafe. Setelah semalaman bongkar-bongkar script netpkg akhirnya saya berhasil meng-edit script netpkg agar dapat digunakan untuk keperluan lokal repositori, jadi tidak perlu download-download lagi untuk proses instalasi programnya

Tahapan-tahapan yang perlu dilakukan untuk dapat menggunakan repositori secara lokal di Zencafe atau Zenwalk disini saya bagi menjadi 3 bagian yaitu :

1. Pembuatan CD yang berisi kumpulan packages-packages

   Proses pembuatan CD ini berfungsi untuk mempermudah penyebaran repositori dari Zencafe (pernah dengar DVD Repositori-nya ubuntu kan ? Nah kita akan buat seperti itu) Untuk pembuatan CD Repositori ini tidak ada aturan-aturan khusus, tetapi yang perlu diperhatikan disini adalah file PACKAGES.TXT dan PACKAGES.TXT.gz

   Ok, sekarang kita langsung saja ke langkah-langkah pembuatannya:

   • Buatlah sebuah direktori untuk menampung packages-packages yang akan dijadikan sebagai repositori, sebagai contoh disini buatlah sebuah direktori OfflinePackages dan masukkanlah package-package yang ingin anda jadikan sebagai repositori kedalam direktori OfflinePackages hingga struktur direktorinya menjadi seperti dibawah ini:
     
     1 2 3 4 5 6 7 8 9 10 11 12

     operatore[OfflinePackages]$ pwd /home/operatore/DATA_OPERATORE/Martinus/OfflinePackages operatore[OfflinePackages]$ ls -l total 0 drwxr-xr-x 2 operatore users 216 2007-10-09 22:05 xap operatore[OfflinePackages]$ ls -l xap/ total 16600 -rw-r--r-- 1 root      root   107027 2007-06-20 02:09 bc-1.06-i486-46.1.tgz -rw-r--r-- 1 operatore users 4190618 2007-04-07 20:47 blogbridge-5.0.1.tgz -rwxr-xr-x 1 operatore users 4960683 2007-02-06 01:51 k3b-1.0rc5-i486-1kjz.tgz -rw-r--r-- 1 operatore users 7710157 2007-06-23 12:33 pidgin-2.0.0-i486-1zc1.tgz operatore[OfflinePackages]$

     
     Note: Anda dapat mengkategorikan packages-packages yang anda masukkan berdasarkan direktori-direktori standart Slackware, bisa juga tidak (tidak mengikuti aturan)
   • Setelah selesai, sekarang buatlah sebuah file bernama PACKAGES.TXT (ingat semuanya ditulis dalam huruf besar, tidak boleh tidak). File PACKAGES.TXT ini berfungsi sebagai metadata yang digunakan oleh netpkg untuk mendaftar packages-packages yang tersedia. Sedangkan isi dari file PACKAGES.TXT ini mempunyai aturan sebagai berikut:
     

     PACKAGE NAME: Nama packages
     PACKAGE LOCATION: Lokasi packages
     PACKAGE SIZE (compressed): Ukuran packages dalam mode kompresi K
     PACKAGE SIZE (uncompressed): Ukuran packages sebenarnya K
     PACKAGE REQUIRED: Dependencies packages yang diperlukan jika ada
     PACKAGE CONFLICTS: *Maap kurang tahu*
     PACKAGE SUGGESTS: *Maap kurang tahu*
     PACKAGE DESCRIPTION: Descripsi packages, taruh dibawah baris ini

     Sedangkan contoh isi file PACKAGES.TXT punya saya adalah sebagai berikut :

     1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67

     PACKAGE NAME:  bc-1.06-i486-46.1.tgz PACKAGE LOCATION:  ./xap PACKAGE SIZE (compressed):  ? K PACKAGE SIZE (uncompressed):  ?

     Untuk deskripsi package, bisa diambil di file slack-desc di setiap packages yang dimasukkan (Maap belum menemukan bagaimana cara meng-otomatisasi pembuatan file PACKAGES.TXT ini)

   • Setelah itu simpanlah file PACKAGES.TXT diatas pada direktori OfflinePackages hingga struktur direktori OfflinePackages menjadi seperti dibawah ini:
     1 2 3 4 5 6 7

     operatore[OfflinePackages]$ pwd /home/operatore/DATA_OPERATORE/Martinus/OfflinePackages operatore[OfflinePackages]$ ls -l total 4 -rw-r--r-- 1 operatore users 1827 2007-10-10 23:59 PACKAGES.TXT drwxr-xr-x 2 operatore users  216 2007-10-09 22:05 xap operatore[OfflinePackages]$

   • Setelah proses pembuatan file PACKAGES.TXT selesai, sekarang buatlah file PACKAGES.TXT.gz dengan cara seperti dibawah ini:
     1 2 3 4 5 6 7 8 9 10 11

     operatore[OfflinePackages]$ ls PACKAGES.TXT  xap operatore[OfflinePackages]$ cp PACKAGES.TXT PACKAGES.TXT.1 operatore[OfflinePackages]$ gzip -9 PACKAGES.TXT operatore[OfflinePackages]$ mv PACKAGES.TXT.1 PACKAGES.TXT operatore[OfflinePackages]$ ls -l total 8 -rw-r--r-- 1 operatore users 1827 2007-10-11 00:59 PACKAGES.TXT -rw-r--r-- 1 operatore users  427 2007-10-10 23:59 PACKAGES.TXT.gz drwxr-xr-x 2 operatore users  216 2007-10-09 22:05 xap operatore[OfflinePackages]$

   • Proses pembuatan CD repositori sudah hampir selesai, sekarang kita tinggal membuat file *.iso-nya kemudian mem-burningnya untuk kemudian disebarkan ke teman-teman atau kolega anda Untuk membuat sebuah file *.iso, sekarang keluarlah dari direktori OfflinePackages dengan mengetikkan cd .. kemudian buatlah file iso dengan menjalankanlah perintah mkisofs -V ZC_OfflineRepository -J -r -o /home/operatore/DATA_OPERATORE/Martinus/Repos.iso /home/operatore/DATA_OPERATORE/Martinus/OfflinePackages/ seperti dibawah ini:
     1 2 3 4 5 6 7 8 9 10

     operatore[OfflinePackages]$ cd .. operatore[Martinus]$ mkisofs -V ZC_OfflineRepository -J -r -o /home/operatore/DATA_OPERATORE/Martinus/Repos.iso /home/operatore/DATA_OPERATORE/Martinus/OfflinePackages/ 59.08% done, estimate finish Thu Oct 11 01:08:02 2007 Total translation table size: 0 Total rockridge attributes bytes: 928 Total directory bytes: 2048 Path table size(bytes): 22 Max brk space used 21000 8473 extents written (16 MB) operatore[Martinus]$

   Nah sekarang file *.iso yang berisi kumpulan-kumpulan repository sudah siap untuk di burning ke dalam CD Blank atau CD kosong dan siap untuk di distribusikan Sekarang mari kita lanjutkan ke proses berikutnya yaitu meng-konfigurasi agar netpkg dapat digunakan untuk keperluan offline

2. Konfigurasi netpkg untuk keperluan offline

   Secara default, netpkg tidak di desain untuk dapat digunakan secara offline. Tetapi berhubung banyaknya teman-teman yang bertanya bagaimana agar netpkg bisa digunakan layaknya synaptic-nya ubuntu, maka sekarang mari kita mulai bermain-main dengan netpkg

   Langkah-langkah yang perlu dilakukan agar netpkg dapat digunakan secara offline adalah :

   • Konfigurasi pada file /etc/netpkg.conf
     Untuk konfigurasi penggunaan repositori secara offline, penulisan pada file /etc/netpkg.conf ini saya menggunakan aturan sebagai berikut:
     Shell

     1	Internet_mirror = file:///mnt/cdrom

     Untuk teman-teman yang tidak ingin terikat, bisa mengganti PATH-nya terserah keinginan sendiri asalkan harus menyertakan Internet_mirror = file:///

   • Konfigurasi pada file /usr/libexec/netpkg-functions
     Setelah konfigurasi pada file /etc/netpkg.conf selesai dilakukan, sekarang kita lakukan konfigurasi pada file /usr/libexec/netpkg-functions hingga menjadi seperti dibawah ini:
     Shell

     1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440 441 442 443 444 445 446 447 448 449 450 451 452 453 454 455 456 457 458 459 460 461 462 463 464 465 466 467 468 469 470 471 472 473 474 475 476 477 478 479 480 481 482 483 484 485 486 487 488 489 490 491 492 493 494 495 496 497 498 499 500 501 502 503 504 505 506 507 508 509 510 511 512 513 514 515 516 517 518 519 520 521 522 523 524 525 526 527 528 529 530 531 532 533 534 535 536 537 538 539 540 541 542 543 544 545 546 547 548 549 550 551 552 553 554 555 556 557 558 559 560 561 562 563 564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579 580 581 582 583 584 585 586 587 588 589 590 591 592 593 594 595

   Setelah melakukan pengeditan pada file /usr/libexec/netpkg-functions selesai, simpanlah hasil editan tersebut kemudian sekarang waktunya untuk mulai menggunakan repositori lokal bikinan sendiri

3. Menggunakan lokal repositori bikinan sendiri

   Hmm… semuanya sudah siap rasanya, sekarang untuk mengetesnya masukkanlah CD repositori yang telah dilakukan pada langkah diatas ke dalam cdrom. Jika file iso-nya belum diburning, buatlah dahulu mount-point pada direktori /mnt dengan mengetikkan perintahmkdir /mnt/cdrom kemudian jalankanlah perintah mount -t iso9660 -o loop Repos.iso /mnt/cdrom seperti dibawah ini agar Zencafe membaca isi file Repo.iso layaknya membaca dari CDROM:

   1 2 3 4 5

   root[Martinus]# mkdir /mnt/cdrom root[Martinus]# mount -t iso9660 -o loop Repos.iso /mnt/cdrom root[Martinus]# ls /mnt/cdrom PACKAGES.TXT  PACKAGES.TXT.gz  xap root[Martinus]#

   Setelah melakukan proses seperti diatas, sekarang jalankanlah netpkg mirror untuk memilih mirror lokal yang telah anda konfigurasi pada file /etc/netpkg.conf ( untuk lokal mirror ditandai dengan file:///path/mirror/) seperti dibawah ini:

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

   root[Martinus]# netpkg mirror Please choose a mirror : 1) http://slackware.linux.or.id/pub/zencafe/i486/zencafe-1.0 2) http://distro.ibiblio.org/pub/linux/distributions/zenwalk/i486/current 3) http://zen-repo.meticul.eu/i486/current 4) http://mirror.meleeweb.net/pub/linux/zenwalk/i486/current 5) http://ftp.nux.ipb.pt/pub/dists/zenwalk/i486/current 6) http://ftp.sh.cvut.cz/MIRRORS/zenwalk/i486/current 7) file:///mnt/cdrom 8) http://linuxpackages.telecoms.bg/Zenwalk 9) http://mirrors.unixsol.org/linuxpackages//Zenwalk 10) http://linuxpackages.inode.at/Zenwalk 11) http://www.software-mirror.com/linuxpackages/Zenwalk 12) http://ftp.scarlet.be/pub/linuxpackages/Zenwalk 13) ftp://ftp.slackware.hu/linuxpackages/Zenwalk 14) http://slackware.mirrors.tds.net/pub/slackware/slackware-current/slackware 15) http://www.tuxgames.net/zenwalk 16) http://users.zenwalk.org/packages #? 7   From now current mirror is : file:///mnt/cdrom Cleaning cache Connecting to mirror Offline mirror detected, switch to other process for getting offline packages metadata Checking offline repository metadata ...... Pointing repository from /mnt/cdrom Computing packages dependencies Computing packages descriptions Creating packages list Getting local packages list Computing packages status Synchronization with file:///mnt/cdrom successful Cleaning temporary files and saving meta information root[Martinus]#

   Ok proses sinkronisasi antara mirror lokal yang ada di CDROM dan netpkg telah berhasil dilakukan, sekarang mari kita cek packages-packages apa saja yang terdapat pada mirror lokal ini dengan cara mengetikkan perintah netpkg list seperti gambar dibawah ini:

   1 2 3 4 5 6

   root[Martinus]# netpkg list [N][xap] Found bc-1.06-i486-46.1.tgz on the repository : not installed [N][xap] Found k3b-1.0rc5-i486-1kjz.tgz on the repository : not installed [I][xap] Found installed pidgin-2.0.0-i486-1zc1.tgz on the repository Cleaning temporary files and saving meta information root[Martinus]#

   Hurray.. semua packages yang terdapat pada file *.iso telah dikenali, sekarang mari kita coba instal salah satu packages dari repositori lokal yang telah kita buat dengan mengetikkan perintah netpkg nama_packages.tgz seperti dibawah ini:

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

   root[Martinus]# netpkg bc-1.06-i486-46.1.tgz   [N][xap] Found bc-1.06-i486-46.1.tgz on the repository : not installed what should I do ? 1) install 2) download 3) skip #? 1 Nothing to do, bc-1.06-i486-46.1.tgz is already in local cache Installing [xap]bc-1.06-i486-46.1.tgz Installing package bc-1.06-i486-46.1... PACKAGE DESCRIPTION: bc: bc is an arbitrary precision calculator language. bc: bc: It allows one to write and execute simple or complex programs bc: to do calculations using arbitrary precision real numbers. bc: bc:   Cleaning temporary files and saving meta information root[Martinus]#

   Mari kita cek, apakah packages bc tersebut benar-benar telah terinstal pada sitem kita dengan mengetikkan perintah ls /var/log/packages dan untuk pembuktian kita coba jalankan perintah bc tersebut seperti dibawah ini:

   1 2 3 4 5 6 7 8 9 10 11 12 13

   root[Martinus]# ls /var/log/packages | grep bc bc-1.06-i486-46.1 glibc-2.3.6-i486-2z40 libcroco-0.6.1-i486-1z28 root[Martinus]# bc bc 1.06 Copyright 1991-1994, 1997, 1998, 2000 Free Software Foundation, Inc.

Ihuiiiiiiii…. sukses sekarang kita dapat menggunakan repositori lokal seperti layaknya teman-teman komunitas ubuntu
