内核编译

一.内核编译

实验环境：
在server5中：

虚拟机至少2048M以上Memory（内存）

实验步骤：
所需要的LVS-FULLNAT和内核源码包

[[e-mail] ~]# ls
asciidoc-8.4.5-4.1.el6.noarch.rpm
Lvs-fullnat-synproxy.tar.gz
newt-devel-0.52.11-3.el6.x86_64.rpm
kernel-2.6.32-220.23.1.el6.src.rpm
slang-devel-2.2.1-1.el6.x86_64.rpm

1.配置高可用yum源

[[e-mail] ~]# vim /etc/yum.repos.d/rhel-source.repo
[rhel-source]
name=Red Hat Enterprise Linux $releasever - $basearch - Source
baseurl=http://172.25.14.250/source6.5
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[LoadBalancer]
name=LoadBalancer
baseurl=http://172.25.14.250/source6.5/LoadBalancer
gpgcheck=0

[HighAvailability]
name=HighAvailability
baseurl=http://172.25.14.250/source6.5/HighAvailability
gpgcheck=0

[ResilientStorage]
name=ResilientStorage
baseurl=http://172.25.14.250/source6.5/ResilientStorage
gpgcheck=0

[ScalableFileSystem]
name=ScalableFileSystem
baseurl=http://172.25.14.250/source6.5/ScalableFileSystem
gpgcheck=0

2.安装内核源码包

[root@server5 ~]# yum install rpm-build -y # rpmbuild命令被用于创建rpm的二进制软件包和源码软件包
[root@server5 ~]# rpm -ivh kernel-2.6.32-220.23.1.el6.src.rpm 
[root@server5 ~]# cd rpmbuild/SPECS/
[root@server5 SPECS]# rpmbuild -bp kernel.spec

3.根据提示，安装对应的安装包

[root@server5 SPECS]# yum install gcc redhat-rpm-config patchutils xmlto asciidoc elfutils-libelf-devel zlib-devel binutils-devel newt-devel python-devel perl-ExtUtils-Embed hmaccalc  -y

4.安装3个安装包

[root@server5 ~]# yum  install asciidoc-8.4.5-4.1.el6.noarch.rpm newt-devel-0.52.11-3.el6.x86_64.rpm slang-devel-2.2.1-1.el6.x86_64.rpm -y

5.从RPM获取内核源代码

[root@server1 SPECS]# rpmbuild -bp kernel.spec

6.重新打开一个server5

[root@server1 ~]# yum provides */rngd
[root@server1 ~]# yum install rng-tools-2-13.el6_2.x86_64 -y
[root@server1 ~]# rngd -r /dev/urandom

7.回到另一个server5

[[e-mail] ~]# tar zxf Lvs-fullnat-synproxy.tar.gz
[[e-mail] ~]# cd rpmbuild/BUILD/kernel-2.6.32-220.23.1.el6/linux-2.6.32-220.23.1.el6.x86_64/
[[e-mail] linux-2.6.32-220.23.1.el6.x86_64]# cp /root/lvs-fullnat-synproxy/lvs-2.6.32-220.23.1.el6.patch .
[[e-mail] linux-2.6.32-220.23.1.el6.x86_64]# patch -p1 < lvs-2.6.32-220.23.1.el6.patch ##打补丁
[[e-mail] linux-2.6.32-220.23.1.el6.x86_64]# vim Makefile #修改配置文件

[[e-mail] linux-2.6.32-220.23.1.el6.x86_64]# make  ##编译
[[e-mail] linux-2.6.32-220.23.1.el6.x86_64]# make modules_install   ##导入模块
[[e-mail] linux-2.6.32-220.23.1.el6.x86_64]# make install 

[root@server5 ~]# cd /boot/grub/
[root@server5 grub]# vim grub.conf #修改引导文件
default=0  ##默认启动
[root@server5 grub]# reboot

二.LVS Tools安装

1. keepalived install

[root@server5 ~]# cd lvs-fullnat-synproxy/
[root@server5 lvs-fullnat-synproxy]# tar zxf lvs-tools.tar.gz
[root@server5 lvs-fullnat-synproxy]# cd tools/keepalived/
[root@server5 keepalived]# ./configure --with-kernel-dir="/lib/modules/`uname -r`/build";
[root@server5 keepalived]# yum install -y popt-devel
[root@server5 keepalived]# make;
[root@server5 keepalived]# make install

2.ipvsadm install

[root@server5 ~]# cd lvs-fullnat-synproxy/tools/ipvsadm/
[root@server5 ipvsadm]# make;
[root@server5 ipvsadm]# make install;
