Centos6.8编译安装keepalived-1.3.5步骤

keepalived-1.3.5 下载 http://keepalived.org/software/keepalived-1.3.5.tar.gz

一 首先安装依赖和编译器

yum -y update kernel kernel-headers   #升级内核
reboot #重新启动电脑
yum -y install gcc make kernel-devel 
yum -y install curl libnl3-devel iptables-devel libnfnetlink-devel ipset-devel openssl-devel net-snmp-devel

二 编译keepalived

#安装在/usr/local/keepalived目录
./configure --prefix=/usr/local/keepalived  \
         --with-kernel-dir=/usr/src/kernels/`uname -r`
make

三 安装keepalived

make install
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
mkdir /etc/keepalived
ln -s /usr/local/keepalived/sbin/keepalived /usr/sbin/
touch /etc/init.d/keepalived
chmod +x /etc/init.d/keepalived
vi /etc/init.d/keepalived

keepalived脚本内容如下

        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
        exit 2
esac
exit $?

四 配置和运行keepalived

 vi /etc/keepalived/keepalived.conf #配置正确
 chkconfig --add keepalived
 chkconfig keepalived on
 service keepalived start

五 查看keepalived运行日志

more /var/log/messages |grep -E "\\[" |grep keepalived
