官方地址：https://www.keepalived.org/download.html

mkdir -p /usr/local/keepalived/package
cd /usr/local/keepalived/package
wget https://www.keepalived.org/software/keepalived-2.0.20.tar.gz
tar -xzvf keepalived-2.0.20.tar.gz
cd keepalived-2.0.20
#創建安裝目錄
mkdir -p /usr/local/keepalived/instance
./configure --prefix=/usr/local/keepalived/instance
make && make install

#將配置文件放到默認路徑下
mkdir /etc/keepalived
cp /usr/local/keepalived/instance/etc/keepalived/keepalived.conf /etc/keepalived/

#將keepalived啓動腳本（源碼目錄下），放到/etc/init.d/目錄下
cp -a /usr/local/keepalived/package/keepalived-2.0.20/keepalived/etc/init.d/keepalived /etc/rc.d/init.d/

#將keepalived啓動腳本變量引用文件放到/etc/sysconfig/目錄下
cp -a /usr/local/keepalived/instance/etc/sysconfig/keepalived /etc/sysconfig/

#將keepalived主程序加入到環境變量/usr/sbin/目錄下：
cp -a /usr/local/keepalived/instance/sbin/keepalived /usr/sbin/
