Keepalived 安装

1、下载

https://www.keepalived.org/download.html

2、上传到linux中，/home/software

3、解压

tar -zxvf keepalived-2.0.18.tar.gz

4、进入到解压后的目录进行configure配置

./configure --prefix=/usr/local/keepalived --sysconf=/etc

• prefix：Keepalived的安装位置；
• sysconf：Keepalived的核心配置文件所在位置，固定位置，如果修改会导致启动不了。
• configure配置过程中可能会出现如下警告信息：

  *** WARNING - this build will not support IPVS with IPv6. Please install libnl/libnl-3 dev libraries to support IPv6 with IPVS.
  

  解决办法：安装libnl/libnl-3依赖，然后重新configure

  yum -y install libnl libnl-devel
  

5、configure配置完成后，开始安装Keepalived

make && make install

至此安装结束！

6、文件位置

通过 whereis keepalived 命令，可以找到keepalived位置

• /etc/keepalived为核心配置文件的位置；
  
• /usr/local/keepalived为keepalived安装的位置。
  

7、Keepalived注册为系统服务

Keepalived的启动是在keepalived/sbin/目录下执行命令./keepalived，启动后关闭只能杀死进程，非常不方便，因此我们可以将Keepalived注册为系统服务，这样就可以方便的开启、关闭和重启。

1、进入到keepalived安装包解压后的文件夹
cd /home/software/keepalived-2.0.18/keepalived/etc/

2、复制服务配置文件
cp init.d/keepalived /etc/init.d/
cp sysconfig/keepalived /etc/sysconfig/

3、重新加载服务配置文件
systemctl daemon-reload

4、注册服务就完成了
启动keepalived：systemctl start keepalived.service
关闭keepalived：systemctl stop keepalived.service
重启keepalived：systemctl restart keepalived.service
