CentOS7安装Keepalived详细步骤

1.首先先去Keepalived官网上下载：官网地址

2.把下载好的Keepalived压缩包上传到我们的CentOS7系统上，然后输入下面解压命令进行解压。

tar -zxvf keepalived-2.0.18.tar.gz

3.先进入Keepalived目录，然后输入配置命令进行配置(--prefix：指明Keepalived的安装位置，--sysconf：指明Keepalived配置文件存放位置，必须放在/etc下面，为了后续Keepalived启动关闭不报错)。

cd keepalived-2.0.18

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

注意：如果执行配置命令，出现以下警告信息，要先进行libnl核心库依赖安装：

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

libnl核心库依赖安装命令：yum -y install libnl libnl-devel

4.执行完上面命令之后，这时候Keepalived目录里面多了个Makefile的文件，这时候我们可以进行安装了。

输入命令：make && make install
这时候可以看到我们已经安装完成了，Keepalived安装在 /usr/local/keepalived 目录下，它的核心配置文件在 /etc/keepalived 目录下。
