Day06 keepalived

前提：需要安装包keepalived-1.2.20.tar.gz   解压  tar zxf  keepalived-1.2.20.tar.gz

（1）进入一级目录  cd keepalived-1.3.5下

（2）编译：./configure  --prefix=/usr/local/keepalived

一边编译一边根据提示下载  比如：yum install -y  gcc/openssl-devel

直到出现

make  && make  install

（3）进入/usr/local/keepalived下

rpm  -q  gcc

进入/usr/local下

scp  -r keepalived/ 172.25.15.4:/usr/local

制作软链接：ln -s /usr/local/keepalived/sbin/keepalived /sbin/

            ln -s /usr/local/keepalived/etc/keepalived /etc/

            ln -s /usr/local/keepalived/etc/sysconfig/keepalived  /etc/sysconfig

            ln -s /usr/local/keepalived/etc/rc.d/init.d/keepalived  /etc/init.d

chmod  +x keepalived

在server4中也进行软链接制作和给权限

（4）在server4中，进入/etc/keepalived下

vim  keepalived.conf

global_defs {

   notification_email {

      root@localhost 

id 51独占

以上内容在server4中要修改i：from keepalived@server4

                            state  改为BACKUP

                            priority  50  数字大的优先级高

开启服务 /etc/init.d/keepalived start
