### ### Now generating a PGP key pair to be used for signing modules. ### ### If this takes a long time, you might wish to run rngd in the background to ### keep the supply of entropy topped up. It needs to be run as root, and ### should use a hardware random number generator if one is available, eg: ### ### rngd -r /dev/hwrandom ### ### If one isn't available, the pseudo-random number generator can be used: ### ### rngd -r /dev/urandom ### + gpg --homedir . --batch --gen-key /root/rpmbuild/SOURCES/genkey gpg: WARNING: unsafe permissions on homedir `.' gpg: keyring `./secring.gpg' created gpg: keyring `./pubring.gpg' created
新开一个终端执行
rngd -r /dev/hwrandom 或者rngd -r /dev/urandom
rpmbuild完成
开始编译LVS FUNNNAT 内核补丁
cd ~/rpmbuild/BUILD/kernel-2.6.32-220.23.1.el6/linux-2.6.32-220.23.1.el6.x86_64 tar zxf Lvs-fullnat-synproxy.tar.gz cp ~/lvs-fullnat-synproxy/lvs-2.6.32-220.23.1.el6.patch . patch -p1<lvs-2.6.32-220.23.1.el6.patch make -j16 #等待编译完成 make modules_install make install
改GRUB 设置刚编译安装的内核为默认启动项
vim /etc/grub.conf default=0
重起服务器
lvs funnat 内核path 完成
real server patch TOA
cp ~/lvs-fullnat-synproxy/toa-2.6.32-220.23.1.el6.patch . patch -p1 <toa-2.6.32-220.23.1.el6.patch make -j16 make modules_install make install

lvs funnat管理工具ipvsadm ，必须安装
cd ~/lvs-fullnat-synproxy/tools/ipvsadm/ make && make install ipvsadm --save > /etc/sysconfig/ipvsadm
lvs高可用工具keeplived ，如果用不到可以不安装
cd ~/lvs-fullnat-synproxy/tools/keepalived ./configure --with-kernel-dir="/lib/modules/`uname -r`/build" make && make install cp keepalived/etc/init.d/keepalived.init /etc/init.d/keepalived mkdir /etc/keepalived/ cp keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf cp keepalived/etc/init.d/keepalived.sysconfig /etc/sysconfig/keepalived
lvs高可用工具quagga，可以配置OSPF等路由协议，如果用不到可以不安装

安装全部完成
配置使用LVS
三台服务器
Real server 1: 10.10.10.51
Real server 2: 10.10.10.52
LVS Directory: 10.10.10.53
VIP: 10.10.10.111
全部服务器关闭selinux 和 iptables
Real server 1
yum install httpd -y echo "Real Server 1" > /var/www/html/index.html service httpd start
Real server 2
yum install httpd -y echo "Real Server 2" > /var/www/html/index.html service httpd start
