下载安装包

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

  1. wget https://www.keepalived.org/software/keepalived-2.0.20.tar.gz

解压

  1. tar -zxvf keepalived-2.0.20.tar.gz

解压后进入到解压出来的目录，看到会有configure，那么就可以做配置了（配置安装和nginx一模一样）

配置

  • prefix：keepalived安装的位置
  • sysconf：keepalived核心配置文件所在位置，固定位置，改成其他位置则keepalived启动不了，/var/log/messages中会报错
    1. ./configure --prefix=/usr/local/keepalived --sysconf=/etc
    配置过程中可能会出现警告信息，如下所示：
    1. *** WARNING - this build will not support IPVS with IPv6. Please install libnl/libnl-3 dev libraries to support IPv6 with IPVS.
    安装libnl/libnl-3依赖，重新configure一下，就可以了
    1. yum -y install libnl libnl-devel

    安装

    1. make && make install
    /etc/keepalived 是核心配置文件
    1. [root@java-t keepalived-2.0.20]# whereis keepalived
    2. keepalived: /etc/keepalived /usr/local/keepalived
