yum -y install kernel-devel*
yum -y install openssl-*
yum -y install popt-devel
yum -y install lrzsz
yum -y install openssh-clients
yum -y install libnl libnl-devel popt

2、开始安装

上传 keepalived-1.2.15.tar.gz 到服务器  /usr/local/  目录下。

进入刚刚的目录： cd /usr/local

解压刚刚的文件： tar -zxvf keepalived-1.2.15.tar.gz

进入解压完的目录：cd keepalived-1.2.15

可以看见下面有个configure文件：

执行配置命令：  ./configure --prefix=/usr/local/keepalived

编译：make 

安装： make install

到这里安装就完成了

1.拷贝执行文件  cp /usr/local/keepalived/sbin/keepalived /usr/sbin/

2.将init.d文件拷贝到etc下,加入开机启动项  cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/keepalived

3.将keepalived文件拷贝到etc下，加入网卡配置  cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

4.创建keepalived文件夹  mkdir -p /etc/keepalived

5.将keepalived配置文件拷贝到etc下  cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf​​​​​​​

6.添加可执行权限  chmod +x /etc/init.d/keepalived

3、加入开机自启

chkconfig --add keepalived     #添加时必须保证/etc/init.d/keepalived存在

chkconfig keepalived on

添加完可查询系统服务是否存在：chkconfig --list

可以看见 keepalived 已经存在了

4、启动

启动：service keepalived start

停止：service keepalived stop

重启：service keepalived restart

4.1 配置日志文件

1.将keepalived日志输出到local0：

                   vi /etc/sysconfig/keepalived

                   KEEPALIVED_OPTIONS="-D -d -S 0"

2.在/etc/rsyslog.conf 末尾里添加:

                     vim /etc/rsyslog.conf

                     local0.*  /var/log/keepalived.log

3.重新启动keepalived和rsyslog服务：

                     service rsyslog restart

                     service keepalived restart

5. 打开防火墙的通讯地址

      iptables -A INPUT -d 224.0.0.18 -j ACCEPT

       /etc/rc.d/init.d/iptables save
