Ubuntu下部署Keepalived

Keepalived是一种防止单点故障的高可用解决方案。

首先下载:

cd /usr

wget http://www.keepalived.org/software/keepalived-1.2.7.tar.gz

解压： www.2cto.com

tar zxvf keepalived-1.2.7.tar.gz

编译之前需要安装几个程序库

[plain]

apt-get install libssl-dev

apt-get install openssl

apt-get install libpopt-dev

然后运行

[plain]

./configure --prefix=/usr

得到如下结果：

[plain]

Keepalived configuration

------------------------

Keepalived version : 1.2.7

Compiler : gcc

Compiler flags : -g -O2

Extra Lib : -lpopt -lssl -lcrypto

Use IPVS Framework : Yes

IPVS sync daemon support : Yes

IPVS use libnl : No

Use VRRP Framework : Yes

Use VRRP VMAC : Yes

SNMP support : No

Use Debug flags : No

编译吧：

make

make install

程序安装到下面几个目录：

/usr/sbin中包含可执行程序keepalived

www.2cto.com

/usr/etc/keepalived/ 中包含了配置文件和例子

/usr/etc/rc.d/init.d/keepalived 是可以作为service的脚本文件,复制到/etc/init.d目录下

修改三处：

[plain]

#. /etc/rc.d/init.d/functions

. /lib/lsb/init-functions

[plain]

#. /etc/sysconfig/keepalived

. /usr/etc/sysconfig/keepalived

因为redhat之外的Linux没有上面两处目录。 www.2cto.com

下面也要修改，将${..} 直接用start替换。

[plain]

start() {

echo -n $"Starting $prog: "

#daemon keepalived ${KEEPALIVED_OPTIONS}

daemon keepalived start

RETVAL=$?

echo

[ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog

}

还要创建目录

[plain]

mkdir -p /var/lock/subsys

现在设置为系统服务

[plain]

update-rc.d keepalived default

安装daemon服务。

apt-get install daemon

好了，终于可以正常启动了。

service keepalived start

关闭用

service keepalived stop
