  Redis 主从不再重复
  默认路径 :/usr/local/redis
  keepalived 默认/etc/keepalived
  检测监控 redis_backup.sh,redis_check.sh,redis_fault.sh redis_master.sh,redis_stop.sh脚本默认 /etc/keepalived/script
  iptables 设置添加 需要开放的端口和地址
  224.0.0.18 是vrrp组播地址 ;
  iptables -A INPUT -d 224.0.0.18 -j ACCEPT
  Master 配置
  global_defs {
  router_id redis1
  }
  vrrp_script chk_redis
  {
  script "/etc/keepalived/scripts/redis_check.sh 127.0.0.1 6379"
  interval 2
  timeout 2
  fall 3
  }
  vrrp_instance redis {
  state MASTER
  interface bond0
  virtual_router_id 100
  priority  100
  nopreempt # no seize,must add
  advert_int 1
  authentication {   #all node must same
  auth_type PASS
  auth_pass 1111
  }
  virtual_ipaddress {
  1.2.3.4/24
  }
  track_script {
  chk_redis
  }
  notify_master "/etc/keepalived/scripts/redis_master.sh 127.0.0.1  1.2.3.1 6379"
  notify_backup "/etc/keepalived/scripts/redis_backup.sh 127.0.0.1  1.2.3.1 6379"
  notify_fault /etc/keepalived/scripts/redis_fault.sh
  notify_stop /etc/keepalived/scripts/redis_stop.sh
  }
  Salve 配置
  global_defs {
  router_id redis101
  }
  vrrp_script chk_redis
  {
  script "/etc/keepalived/scripts/redis_check.sh 127.0.0.1 6379"
  interval 2
  timeout 2
  fall 3
  }
  vrrp_instance redis {
  state BACKUP
  interface bond0
  virtual_router_id 90
  priority  100
  advert_int 1
  authentication {   #all node must same
  auth_type PASS
  auth_pass 1111
  }
  virtual_ipaddress {
  1.2.3.4/24
  }
  track_script {
  chk_redis
  }
  notify_master "/etc/keepalived/scripts/redis_master.sh 127.0.0.1  1.2.3.2 6379"
  notify_backup "/etc/keepalived/scripts/redis_backup.sh 127.0.0.1  1.2.3.2 6379"
  notify_fault /etc/keepalived/scripts/redis_fault.sh
  notify_stop /etc/keepalived/scripts/redis_stop.sh
  }
