INTRODUCTION
In some cases, the setup program cannot compile the
necessary kernel modules or prepare the required execution
environment for the product. Normally, the setup program
informs you about this problem and refers you to this file.
Section I of this file describes how to build and install
the kernel module. You may need to read that section if you
have a custom kernel or a nonstandard location of the kernel
source files.
I. BUILDING AND INSTALLING THE KERNEL MODULE
The product can be installed in the following Linux
distributions with kernel from 2.6.9 to 5.1 and
glibc 2.3.4 or later:
(a) Red Hat Enterprise Linux 4.x, 5.x, 6.x, 7.0, 7.1,
7.2, 7.3, 7.4, 7.5, 7.6, 8.0
(b) Ubuntu 9.10, 10.04, 10.10, 11.04, 11.10, 12.04,
12.10, 13.04, 13.10, 14.04, 14.10, 15.04, 15.10, 16.04,
16.10, 17.04, 17.10, 18.04, 18.10
(c) Fedora 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21,
22, 23, 24, 25, 26, 27, 28, 29, 30
(d) SUSE Linux Enterprise Server 10 and 11
SUSE Linux Enterprise Server 12 – supported on file
systems, except for Btrfs
(e) Debian 4, 5, 6, 7.0, 7.2, 7.4, 7.5, 7.6, 7.7, 8.0,
8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 9.0, 9.1,
9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8
(f) CentOS 5.x, 6.x, 7, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6
(g) Oracle Linux 5.x, 6.x, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6
-- both Unbreakable Enterprise Kernel and Red Hat
Compatible Kernel
(h) CloudLinux 5.x, 6.x, 7, 7.1, 7.2, 7.3, 7.4, 7.5
(i) ClearOS 5.x, 6.x, 7, 7.1, 7.4
(j) ALT Linux 7.0
In any of these distributions, the setup program normally
automatically compiles the kernel module that is necessary
for the product to work.
If the setup program cannot compile the kernel module, you
will need to do this manually, as follows.
You need to install the kernel source files, the appropriate
configuration file, and all packages that are required for
building the kernel. These packages include "gcc", "make",
and "kernel-devel". You will be prompted about the
necessary packages when installing the kernel source files.
Normally, you can build and install the "snapapi" kernel
module by running the "dkms" commands as follows:
# dkms build -m <MODULE_NAME> -v <MODULE_VERSION> \
--config <CONFIG_FILE> --arch <KERNEL_ARCH> \
--kernelsourcedir <PATH_TO_KERNEL_SOURCES>
# dkms install -m <MODULE_NAME> -v <MODULE_VERSION> \
--config <CONFIG_FILE> --arch <KERNEL_ARCH> \
--kernelsourcedir <PATH_TO_KERNEL_SOURCES>
In these commands:
<MODULE_NAME> must be one of the following:
(a) For 2.4.x kernels: snapapi
(b) For 2.6.x and 3.x kernels: snapapi26
<MODULE_VERSION> is the version of the "snapapi" module.
You can determine it by running the following command:
# ls /usr/src | grep snapapi
For example, if the name of the directory is
snapapi26-0.7.64, the value of <MODULE_VERSION> is: 0.7.64
<CONFIG_FILE> is the name of your kernel configuration
file. This file is usually located in the /boot directory.
Specify the full file name, for example:
/boot/config-2.6.31-14-generic
<KERNEL_ARCH> is the type of kernel architecture, for
example: i686. You can detect the value for <KERNEL_ARCH> by
running the following commands:
(a) For RPM-based distributions, such as Red Hat
Enterprise Linux, CentOS, or Fedora:
# rpm -q --queryformat "%{ARCH}\n" kernel
(b) For distributions not based on RPM, such as
Ubuntu:
# uname -m
For details about using the dkms utility, refer to the dkms
man page.
After successfully building and installing the kernel
module, you can run the product to check its functionality.
The appropriate kernel modules will be loaded automatically.
II. FAQ
Q: How do I run the .i686 or .x86_64 installation file?
A: This is a standard binary file. To start the
installation, run the following commands:
# chmod +x <FILE_NAME>
# ./<FILE_NAME>
Here, <FILE_NAME> is the name of your .i686 or .x86_64
installation file.
The setup program uses the RPM Package Manager (RPM).
Before installing the product on a system that does not
use RPM, such as an Ubuntu system, you need to install RPM;
for example, by running the following command as the root
user:
#apt-get install -y rpm
Q: Is the .i686 installation file compatible with my x86_64
architecture?
A: No, you must download and install the corresponding
.x86_64 installation file instead of the .i686 installation
file. The installation procedure is the same.
Q: Can I install the product on an IA64 system?
A: No, this architecture is not supported by the product.
Q: The setup program cannot find kernel source files in the
/lib/modules/<MY_KERNEL>/build or in the
/lib/modules/<MY_KERNEL>/source directory. What should I do?
A: This usually means that you need to install the kernel
source files corresponding to your kernel version.
The following commands install the kernel source files
in Debian and Ubuntu:
$ sudo apt-get update
$ sudo apt-get install linux-headers-`uname -r`
$ sudo apt-get install linux-image-`uname -r`
The following command installs the kernel source files
in Red Hat Enterprise Linux and Fedora:
# yum install kernel-devel-`uname -r`
