Run the mkisofs command to create a redhat enterprise linux (RHEL6.4) ISO boot image. Run the following command in red hat's official document Installation_Guide (I will put it in a shell script file mkcustiso. sh) [cpp] mkisofs-quiet-V "make rhel iso files" \-J-R-T-v-boot-info-table-no-emul-boot \-boot-load -size 4 \-B isolinux/isolinux. bin \-c boot. cat \-o. /rhelcustom. iso. /rheliso process: 1. first extract the redhat official image rhel-server-6.4-x86_64-dvd.iso. /rheliso [plain] bsdtar-C. /rheliso-xf Rhel-server-6.4-x86_64-dvd.iso 2. Modify its isolinux. cfg file as needed, and put ks. cfg in The./rheliso directory. 3. modify. /rheliso/isolinux. binfile permission. Otherwise, the error [plain] chmod u + wx. /rheliso/isolinux. bin 4. run the script mkcustiso. sh finally obtains its own rhelcustom. iso file, which can be used to install the system. Note: isolinux. the binfile is a relative path (relative to rheliso). Otherwise, the error mkisofs: uh ah, I can't find the boot image 'isolinux. bin"
