LINUX installation problem summary

Summary of LINUX installation problems-general Linux technology-Linux programming and kernel information. The following is a detailed description. LINUX installation problem summary

Q: My friends, I am a new LINUX user. I want to know how to create a LINUX boot disk!
A: (RedHat is used as an example ). The/images directory contains the boot. img and supp. img files. boot. img creates the boot disk and supp. img creates the extension disk. Run rawrite.exe in/dosutils.
Enter disk image source file name: directory/boot. img
Enter target diskette drive::

Q: How can I install the rpm file?
A: 1. Install A package # rpm-ivh rpm file
2. Upgrade a package # rpm-Uvh rpm file
3. Remove a package # rpm-e

Q: How do I directly display a graphical login menu when redhat is started?
A: root Login
Linuxconf config-> boot mode-> Mode-> default boot mode: Graphics & Network pthinker

Q: An error occurred while installing ORACLE?
A: 1) copy the ORACLE orainst directory to the hard disk and run oratab first. sh (2) the installation of oracle 8.0.5 is related to your Linux version. The installation of the 2.1 and 2.2 cores is not the same! (3) Your D version is the standard version of oracle 8.0.5, and many options are not available. Download an Enterprise Edition or oracle 8i for Linux :)

Q: I want to recompile the kernel to avoid unexpected errors. I want to create a drive with the original core first. How can I do this?
A: How to Create A boot floppy disk: Enter the/boot/directory and run the rdev command to set the root device as the LINUX root file system. Rdev vmlinuz/dev/hda? ? Find a formatted floppy disk based on your system and execute dd if =/boot/vmlinuz of =/dev/fd0 bs = 8192. Dd commands are dangerous. Be careful.
You can use linuxconf to add the new core to the configuration, which is very convenient. Don't forget lilo again, otherwise you will have fun .;)

Q: cannot lilo be installed?
A1: First, check whether your hard disk is set as the master hard disk. I have encountered that the machine only has one HDD, but if it is set as the slave hard disk, LILO cannot be installed, everything is OK.
A2: During installation, LILO is installed in the First sector of boot partition. It may not be installed. Leave it alone. After installation, start it with a floppy disk and modify/etc/lilo. conf boot =... change the line to boot = dev/hda1 and run the lilo command. If there is no error message, you can.

Q: If the NT partition is in NTFS format, how does one coexist with LINUX?
A: If NT is installed in the NTFS partition, it is very dangerous to install Linux on some hard disks! If fdisk in Linux is used to change any information about NT partitions, such as set active, it may cause NT crash, the main reason is that NT cannot correctly process the NTFS partitions processed by Linux fdisk, And the kernel File Corruption error will be reported during startup. In case of such an error, it is very likely that the same thing will happen every time in the future. However, I have found this error only on hard disks with a fireball greater than GB. Other hard disks do not seem to have similar problems. In addition, as far as I know, this error occurs only on RedHat, and Debian and Slackware won't cause such a fault (not quite clear why ). If you want to install NT and Linux on the same hard disk, you must install the system directory of NT on FAT. Otherwise, you will not be able to save yourself. :-)

Q: Why is there no movement after L is displayed after startup? Thank you!
A: A large hard disk may be used. You can set LBA mode to CHS mode in CMOS, or change the hard disk read/write mode to compatible with A small hard disk. For more information about toolbox, see the articles about LILO in "articles.


Q: How to install I740?
A: Go to the ftp://ftp.precisioninsight.com/pub/pi/XBF to download the XBF-i740-glibc-1.0.0-1.i386.rpm (this is the rpm installation package for Red Hat) and the xf86config-glibc-1.0.0.i386.tgz.
Perform the following operations:
(1) rpm-ivh XBF-i740-glibc-1.0.0-1.i386.rpm
(2) ln-sf/usr/X11R6/bin/XBF_i740/etc/X11/X
(3) tar xvzf xf86config-glibc-1.0.0.i386.tgz
(4) Run "xf86config" and you can find the i740 driver in the display card database.

Q: How do I configure Trident9685 in RedHat Linux5.1?
A: Trident9685 (2 MB memory) in the RedHat Linux5.1 XFree86-3.3.1-14, the system can automatically identify as Tr9660, in the selection of display optional NEC MultiSync 3D, after the system test, the display mode is 800*600 8 bit. If you select let me choose, you can select 800*600 16 bit. After the system is installed, restart it. Type startx to go to X11, and the vertical refresh frequency of 70Hz is supported. Redlinux

Q: How to Use the nVIDIA Riva TNT2 Vanta Graphics Accelerator card in Linux?
A1: Download a driver to the primary page of movie dia. Its name is riva-x-glx-1.0-glibc-i386.tar.gz. I have installed movie bully TNT2.
A2: simply use the new version of software, such as turbolinux4.0, to directly support it.

Q: How do I set an I740 video card on Lenovo benyue 2000.
A: I installed REDHAT6 on Lenovo benyue 2000 and downloaded the following video card support. Ftp://ftp.freesoft.cei.gov.cn/pu... bc-1.0.0-1.i386.rpm ftp://ftp.freesoft.cei.gov.cn/pu libc-1.0.0.i386.tgz... install according to instructions, and then run xf86config
1. Select PS/2 with the mouse, and simulate the three keys.
2. Use XKB and select the MS keyboard
3. Video Card 311: normal I740
4. Display setting Scan Frequency input: synchornization Horizontal: 30-69 Vertical: 50-120 data is obtained from the display description. Then set the resolution and save it. After startx, everything is normal.
Here is a tip: if you do not set your machine name, x windows will wait for a long time for the first time, only a gray screen and X-type cursor will appear, just like a crash. Please be patient and try drinking water or smoke a cigarette. Of course, the direct method is to set your machine name, edit/etc/hosts, and add a name after the IP address of your machine. Remember: Be patient.

Q: How do I set the sound card of yamaha 724 (PCI) in linux?
A: First determine your kernel version, preferably 2.2.X. re-compile the kernel and select the chip type, IO address, interrupt, DMA of your sound card in the options... compile and install the kernel to see if you can recognize your sound card.

Q: My Nic works properly with the ne2000 driver in win95, but cannot be found in linux?
A: It is estimated that it is A PnP problem. You may need to use the pnpdump and isapnp programs to set your Nic first. After the parameter is adjusted, add the isapnp line to/etc/rc. before the d/rc file, that is, after the annotation lines and before doing other things, use isapnp to set all your PnP cards, and then talk about other things.
Note:
1.3c509 Nic is recommended to use the 3C5X9XFG. EXE program of the manufacturer to set parameters and disable PnP. In this way, it is no problem to use it in Linux.
2. Some of the ne2000 compatible cards are ISA/PnP cards. This type of PnP Nic can only be used after isapnp is configured.

Q: My Nic is 3C905B of 3COM. Do you know where to find its driver?
A: You can directly use 3c59x. o. If it cannot be recognized, it may be 3c509b is set to PnP. If Linux does not recognize or recognize irq, try disable PnP first.

Q: How can I use DLINK220 ISA PNP in TURBO? Does LINUX mean that all internal cats recognize it? How should I configure it? Thank you !!
A: I don't know which company Linux you are using? If it is Turbo4: turbopnp/turbopnpcfg search plug-and-play ISA/PCI
Device (I think Turbo is better than RH in this aspect). If you find it, configure it manually. The inner cat uses cua2/cua3, cua2 <=> com3 .. turbonetcfg: configure the NIC.

Q: How do I configure an Accton PNP Nic?
A: Use the NE2000 driver to drive the Accton PNP Nic, modify/etc/conf. modules (if not, create one), and add the following content:
Alias eth0 ne options ne io = 0x300 or add the following content to lilo. conf: append = ether = 10, 0x300, eth0

Q: Why cannot I find the NE2000 Nic after Linux is started?
A: The LINUX Nic of NE2000 cannot be detected automatically. You need to set it manually. Use the drive disk of the NIC to find out the NIC interrupt and I/O, modify/etc/conf. modules, and add the following content:
Alias eth0 ne options ne io = 0x300
Or Add the following content to lilo. conf: append = ether = 10, 0x300, eth0

Q: The RedHat Linux 6.0 has already been dial-up but cannot be browsed using Netscape. Why?
A: Generally, it is a dns error. Add NAMESERVER In the dialing configuration.

Q: How should I set up a cat to connect to the INTERNET through a vswitch, that is, to set an external line of 0 and 9 first?
A: If you dial 169, you only need to add 0,169. If you do not get through, add another one. This will delay the operation and wait for the switch to respond.

Q. Dialing cannot work. Why?
A. There are many reasons why the dial-up network does not work.
1) the Modem cannot be used for dialing. If the Modem does not have a dialing sound, this indicates that your connection has not started. Check the error message of PPPD in var/log/messages. You can run minicom, enter. the modem should return OK. if no result is returned, your serial port configuration is incorrect. Run TurboPPPCfg again to confirm that the modem device is correctly configured. And it has been connected to/dev/modem. Soft Modem is not supported in Linux.
2) the modem has started dialing, but cannot connect to the ISP * If the ISP uses PAP authentication, you must enable the PAP option in TurboPPPCfg. At the same time, make sure that your password and user name have been entered correctly. * If the ISP does not use PAP, but you use PAP, a similar problem may occur. * The data format of the modem is incorrect. You can run minicom, enter AT & F1. then enter AT & W. to exit.
3) built-in ISDN does not work-Most built-in ISDN devices cannot work properly in Linux. If you want to purchase ISDN devices for Linux, please purchase an ISDN card that supports standard serial equipment, or an external ISDN card

Q: My mouse is LOGITEGH. It indicates that it is supported and cannot be moved during installation or XWINDOWS. Who can tell me WHY?
A: It should be automatically tested during installation. The Logitech Mouse seems to be basically three-key. Is the installation correct? After LINUX is started, log on and move the MOUSE. Usually we should see the box-like cursor.

Q: after detecting the RAID array, VFS: Cannot open root device Kernel panic: VFS: Unable to mount root fs on may be normal. no modification was made between several boot times. but the time is good or bad. why? Use RedHat 6.0.
A: Check the SCSI channel and ID. This may be the case. When installing LINUX, you are not connected to a raid device or are powered on. You have installed LINUX on a local SCSI disk. After you restart the RAID system, the root file system still exists on the local SCSI disk, but the new disk is added. Therefore, the number of the primary and secondary devices on the local disk has changed, that is, the drive letter has changed. Therefore, changing the channel number and ID of the RAID disk may be valid.
