keepalived的安装及问题定位

安装

下载安装包：

wget http://www.keepalived.org/software/keepalived-1.1.20.tar.gz# cd /usr/local/src # tar -zxvf keepalived-1.2.18.tar.gz # cd keepalived-1.2.18 # ./configure --prefix=/usr/local/keepalived # make && make install 

默认目录是/usr/local   

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

复制到默认路径:  

# cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/   # cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/   #---这句不用 ln -s /usr/local/sbin/keepalived /usr/sbin/   # ln -s /usr/local/keepalived/sbin/keepalived /sbin/  

如果存在先删除

find keep*  rm keep  cp /usr/local/keepalived/sbin/keepalived  /usr/sbin/  

开机启动

# chkconfig keepalived on
