keepalived安装

1 软件信息

软件：keepalived

版本：1.2.15

2 keepalived安装

主要步骤：解压、编译、安装、添加到系统服务启动项（需要root权限），因为要绑定网卡。

 

wget http://www.keepalived.org/software/keepalived-1.2.15.tar.gz

tar -zxf keepalived-1.2.15.tar.gz

cd keepalived-1.2.15

mkdir -p ~/keepalived

yum install -y openssl openssl-devel 

$ ./configure --prefix=/home/rhkf/keepalived && make && make install

 

[rhkf@cluster6 ~]$ ls keepalived

bin etc sbin share

 

$ cd ~/keepalived

# cp etc/rc.d/init.d/keepalived /etc/rc.d/init.d/

# cp etc/sysconfig/keepalived /etc/sysconfig/

# cp -r etc/keepalived /etc/

# cp sbin/keepalived /usr/sbin/

# vi /etc/keepalived/keepalived.conf

 

 

[root@cluster5 ~]# cd /etc/keepalived/

[root@cluster5 keepalived]# ls

keepalived.conf samples

[root@cluster5 keepalived]# cat keepalived.conf

}

}

/home/rhkf/keepalived/shutdown.sh

#!/bin/bash

systemctl stop keepalived.service

 

 

由此安装完毕。

 

 

启停keepalived的，两种办法

service keepalived start

service keepalived stop

是因为：

[root@cluster5 init.d]# pwd

/home/rhkf/keepalived/etc/rc.d/init.d

[root@cluster5 init.d]# ls

keepalived

 

[root@cluster5 init.d]# ll /etc/init.d/keepalived

-rwxr-xr-x 1 root root 1308 Apr 11 10:40 /etc/init.d/keepalived

 

 

也可以：

[root@cluster5 init.d]# /usr/sbin/keepalived

因为它是二进制文件：

[root@cluster5 init.d]# file /usr/sbin/keepalived

/usr/sbin/keepalived: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=6a17cc0069bd2d6c818d1f1ad85d75d318cc5b00, stripped

[root@cluster5 init.d]#

这种方法只能kill -9 pid

 

 

总结：

只能在root用户下操作

编译源码./configure --prefix=/home/rhkf/keepalived && make && make install

编译成功后的各个文件拷贝到系统的各个目录下，启动即可。
