keepalived1.4.0安装启动卸载

下载地址：http://www.keepalived.org/

2.安装keepalived

解压

tar -zxvf keepalived-1.4.0.tar.gz   

安装gcc命令

yum install -y gcc openssl-devel popt-devel  

 

安装好gcc后

cd keepalived-1.4.0进入解压的keepalived目录下，执行

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

  

在keepalived-1.4.0目录里make编译和安装

 make && make install 

 以上步骤如果没有错误，则说明编译安装成功。但此时还不能直接使用安装的keepalived，需要拷贝几个文件到指定的目录下才可以直接使用。拷贝的文件如下：

cp keepalived-1.4.0/keepalived/etc/init.d/keepalived    /etc/init.d/ 

mkdir /etc/keepalived

cp /usr/local/keepalived/etc/keepalived/keepalived.conf    /etc/keepalived/  

cp keepalived-1.4.0/keepalived/etc/sysconfig/keepalived   /etc/sysconfig/  

cp /usr/local/keepalived/sbin/keepalived  /usr/sbin/ 

　　

 复制完后就可以启动keepalived

查看指定keepalived安装目录

whereis keepalived

 启动之前执行

systemctl daemon-reload

启动keepalived

systemctl start keepalived.service

停止keepalived

systemctl stop keepalived.service

验证是否启动成功

ps -aux | grep keepalived  

正常启动后，这里有3条记录，其中一个是父进程，负责监控其子进程。一个是vrrp子进程，另外一个是checkers子进程。其他情况说明启动失败。

设置开启启动：

chkconfig keepalived on

2.keepalived 卸载

进入keepalived解压目录的keepalived目录下,

cd /root/java/keepalived/keepalived-1.4.0

 执行命令：

make uninstall

然后删除我们安装时候拷贝相关文件

rm -rf /etc/init.d/keepalived 

rm -rf  /etc/keepalived/ 

rm -rf  /etc/sysconfig/keepalived 

rm -rf  /usr/sbin/keepalived  

rm -rf  /lib/systemd/system/keepalived.service

这样keepalived就删除完了
