百度百科解释：
keepalived 是一个类似于 layer3, 4 & 7 交换机制的软件，也就是我们平时说的第 3 层、第 4 层和第 7 层交换。Keepalived 的作用是检测 web 服务器的状态，如果有一台 web服务器死机，或工作出现故障，keepalived 将检测到，并将有故障的 web 服务器从系统中剔除，当web服务器工作正常后 keepalived 自动将 web 服务器加入到服务器群中，这些工作全部自动完成，不需要人工干涉，需要人工做的只是修复故障的 web 服务器。
1、安装
#安装依赖包 yum install -y curl gcc openssl-devel libnl3-devel net-snmp-devel #yum安装软件 yum install -y keepalived
systemctl start keepalived //启动 keepalived systemctl enable keepalived //加入开机启动 keepalived systemctl restart keepalived //重新启动 keepalived systemctl status keepalived //查看 keepalived 状态
方法二：源码包
1.mkdir /opt/software #建立一个目录，用来存放软件包
2.cd /opt/software #切换到该目录下
3.wget https://www.keepalived.org/software/keepalived-2.0.20.tar.gz #联网下载，也可以windows下载好，上传进来
4.tar xvf keepalived-2.0.20.tar.gz
5.mv keepalived-2.0.20.tar.gz /usr/local/src
6.cd /usr/local/src/keepalived-2.0.20
7.
yum install -y curl gcc openssl-devel libnl3-devel net-snmp-devel
yum -y install openssl openssl-devel
yum -y install libnl libnl-devel
yum -y install libnfnetlink-devel
8.完成后会在以下路径生成：
/usr/local/keepalived/ /usr/local/keepalived/bin /usr/local/keepalived/etc /usr/local/keepalived/sbin /usr/local/keepalived/share --------------- --------------- /usr/local/keepalived/etc/keepalived/keepalived.conf /usr/local/keepalived/etc/sysconfig/ /usr/local/keepalived/sbin/keepalived
9.初始化启动
# keepalived 启动脚本变量引用文件，默认文件路径是 /etc/sysconfig/，也可以不做软链接，直接修改启动脚本中文件路径即可（安装目录下） [root@localhost /]# cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/keepalived # 将keepalived 主程序加入到环境变量（安装目录下） [root@localhost /]# cp /usr/local/keepalived/sbin/keepalived /usr/sbin/keepalived # keepalived 启动脚本（源码目录下），放到 /etc/init.d/ 目录下就可以使用 service 命令便捷调用 [root@localhost /]# cp /usr/local/src/keepalived-2.0.20/keepalived/etc/init.d/keepalived /etc/init.d/keepalived # 将配置文件放到默认路径下 [root@localhost /]# mkdir /etc/keepalived [root@localhost /]# cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf
卸载keeplived工作路径
[root@localhost /]# cd /usr/local/src/keepalived #源码所在目录（根据实际情况进入对应目录）
[root@localhost keepalived]#make uninstall
删除相关文件，有时系统版本差异，删除的时候，先查看该路径是否存在文件，以免删除错误，要仔细了。不要复制我的路径
#删除keepalived [root@localhost /]# rm -f /usr/local/keepalived/sbin/keepalived [root@localhost /]# rm -f /usr/local/keepalived/etc/rc.d/init.d/keepalived [root@localhost /]# rm -f /usr/local/keepalived/etc/sysconfig/keepalived [root@localhost /]# rm -rf /usr/local/keepalived/etc/keepalived [root@localhost /]# rm -f /usr/local/keepalived/bin/genhash [root@localhost /]# rm -rf /usr/local/keepalived [root@localhost /]# rm -rf /etc/keepalived [root@localhost /]# rm -f /etc/rc.d/init.d/keepalived [root@localhost /]# rm -f /usr/sbin/keepalived [root@localhost /]# rm -f /etc/sysconfig/keepalived [root@localhost /]# rm -f /etc/systemd/system/multi-user.target.wants/keepalived.service
测试是否卸载成功
[root@localhost /]# serive keepalived satrt [root@localhost /]# systemctl start keepalived 当命令无效时，证明卸载成功。 相关操作命令 centOs： [root@localhost /]# systemctl start keepalived -- 启动 [root@localhost /]# systemctl stop keepalived --关闭 [root@localhost /]# ps aux|grep keepalived --查看进程 linux： [root@localhost /]# service keepalived start -- 启动 [root@localhost /]# service keepalived stop --关闭 [root@localhost /]# ps aux|grep keepalived --查看进程
