keepalived安装（个人笔记）

FragranceM

• 　　
  
  
• 　　wget http://www.keepalived.org/software/keepalived-1.2.1.tar.gz
  
• 　　tarzxf keepalived-1.2.1.tar.gz ；cdkeepalived-1.2.1；
  
  
• ./configure--with-kernel-dir=/usr/src/kernels/2.6.18-164.el5-i686 &&make&& make install  
  　　内核需要查看，，，如果是32位的自行修改
  
• keepalived 解决configure: error: Popt libraries is required  需要安
  yum install popt-devel
  
• 　　修改keepalived为系统服务：
  
  
  
• DIR=/usr/local/ ;cp $DIR/etc/rc.d/init.d/keepalived  /etc/rc.d/init.d/
  
• cp $DIR/etc/sysconfig/keepalived/etc/sysconfig/ && mkdir -p /etc/keepalived
  
• cp $DIR/sbin/keepalived /usr/sbin/
  
• 　　修改配置文件/etc/keepalived/keepalived.conf为一下内容:服务端配置
  
• 　　! Configuration File for keepalived

• 　　查看日志tail -fn 100 /var/log/message 日志一直在滚动没有加载ip_vs模块
  
• 　　modprobe ip_vs     然后lsmod | grep ip_vs查看模块
  
• 　　同样客户端也需要安装keepalived安装同样配置文件改一下上面几个地方MASTER要改成BACKUP，mysql.sh脚本里面写上/etc/init.d/keepalived stop即可
  
• 　　然后在测试，因为之前mysql主从已经安装好这里不再安装，，直接测试
  
• 　　首先授权漂移的ip地址或者在论坛配置文件下更改也可以，，测试停掉主服务器mysql用主服务器ip还可以正常访问论坛即可
