操作系统Centos7,关闭selinux,关闭防火墙
1、备份和修改基础仓库到163 yum install wget -y && cd /etc/yum.repos.d/ && mv CentOS-Base.repo CentOS-Base.repo.back wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
2、安装epel仓库和修改epel仓库地址到阿里云 yum install epel-release -y wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
3、安装开发环境 yum group list yum group install Development Tools -y
4、下载lvs源码包 wget -O /usr/local/src/ipvsadm-1.26.tar.gz http://www.linuxvirtualserver.org/software/kernel-2.6/ipvsadm-1.26.tar.gz yum install ipvsadm -y #(推荐安装方法，这种方法版本比较高)
5、下载keepalived源码包 wget -O /usr/local/src/keepalived-2.0.19.tar.gz https://www.keepalived.org/software/keepalived-2.0.19.tar.gz
6、安装依赖环境 yum -y install libnl-devel popt-devel popt-static openssl-devel libnfnetlink-devel
7、编译安装lvs tar zxf /usr/local/src/ipvsadm-1.26.tar.gz -C /usr/local/src cd /usr/local/src/ipvsadm-1.26 make && make install (yum 安装不需要编译)
8、测试ipvsadm 和检测lvs 的ip_vs
ipvsadm -L -n
lsmod | grep ip_vs
9、编译安装keepalived tar zxf /usr/local/src/keepalived-2.0.19.tar.gz -C /usr/local/src cd /usr/local/src/keepalived-2.0.19 ./configure --prefix=/usr/local/keepalived make && make install mkdir /etc/keepalived cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/ cp /usr/local/src/keepalived-2.0.19/keepalived/etc/init.d/keepalived /etc/init.d/ cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/ cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
测试keepalived /etc/init.d/keepalived start ps axu|grep keepalived tail -f /var/log/message
