keepalived源码安装

1.在新机器上安装如下软件
yum -y install gcc pcre-devel zlib-devel openssl-devel make gcc gcc-c++ ncurses-devel bison openssl-devel libnl libnl-devel libnfnetlink-devel wget

2.进入/usr/local/src目录下，wget方式下载
cd /usr/local/src
wget https://www.keepalived.org/software/keepalived-2.0.20.tar.gz

3.解压缩
tar -zxvf keepalived-2.0.20.tar.gz
将解压的目录移动到/usr/local/keepalived下并进入移动后的目录
cd /usr/local/keepalived/

5.生成makefile文件：
./configure

6.编译安装在/usr/local/keepalived/中
make && make install
检查安装结果：echo $? 如果返回值是0，就是执行成功；如果是返回值是0以外的值，就是失败。

7.完成后会在以下路径生成：
/usr/local/etc/keepalived/keepalived.conf
/usr/local/etc/sysconfig/keepalived
/usr/local/sbin/keepalived

8.将配置文件放到默认路径下：
mkdir /etc/keepalived/
cp /usr/local/keepalived/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/

9.将keepalived启动脚本（源码目录下），放到/etc/init.d/目录下：
cp /usr/local/keepalived/keepalived/etc/init.d/keepalived /etc/rc.d/init.d/

10.将keepalived启动脚本变量引用文件放到/etc/sysconfig/目录下：
cp /usr/local/keepalived/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

11.将keepalived主程序加入到环境变量/usr/sbin/目录下：
cp /usr/local/sbin/keepalived /usr/sbin/

12.添加keepalived到系统服务
chkconfig --add keepalived

13加入开机启动 （还存在问题）centos7自启项已不用chkconfig改为：systemctl list-unit-files
chkconfig keepalived on

14.启动/停止/查看状态
systemctl status keepalived.service
systemctl start keepalived.service
systemctl stop keepalived.service
service keepalived start/stop/status

15.配置lvs自己上网查
