                      keepalived配置文件   主从配置一样，需要修改优先级

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

global_defs {    router_id REDIS05 }         vrrp_instance VI_5 {                 state BACKUP                 interface bond0                 virtual_router_id 85                 priority 150                 authentication {                              auth_type PASS                              auth_pass redis10                 }                 advert_int 2                 virtual_ipaddress {                     1.1.1.1                 }                 notify_master /data/scripts/redis_master.sh                 notify_backup /data/scripts/redis_backup.sh                 notify_fault  /data/scripts/redis_fault.sh                 notify_stop   /data/scripts/redis_stop.sh         }

四个redis脚本的内容

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41

[iyunv@BJ-M5-GXH-REDIS-20-12 scripts]# cat redis_backup.sh #!/bin/bash           REDISCLI="/data/server/redis/bin/redis-cli" LOGFILE="/data/logs/redis/keepalived-redis-state.log"           echo "[backup]" >> $LOGFILE date >> $LOGFILE echo "Being slave...." >> $LOGFILE 2>&1 #sleep 25 echo "Run SLAVEOF cmd ..." >> $LOGFILE $REDISCLI -p 6359 SLAVEOF 1.1.1.1 6359 >> $LOGFILE  2>&1 [iyunv@BJ-M5-GXH-REDIS-20-12 scripts]# cat  redis_fault.sh #!/bin/bash LOGFILE="/data/logs/redis/keepalived-redis-state.log" echo "[fault]" >> $LOGFILE date >> $LOGFILE [iyunv@BJ-M5-GXH-REDIS-20-12 scripts]# cat redis_master.sh #!/bin/bash           REDISCLI="/data/server/redis/bin/redis-cli" LOGFILE="/data/logs/redis/keepalived-redis-state.log"           echo "[master]" >> $LOGFILE date >> $LOGFILE echo "Being master...." >> $LOGFILE 2>&1 echo "Run SLAVEOF NO ONE cmd ..." >> $LOGFILE $REDISCLI -p 6359 SLAVEOF NO ONE >> $LOGFILE  2>&1 [iyunv@BJ-M5-GXH-REDIS-20-12 scripts]# cat redis_stop.sh #!/bin/bash LOGFILE="/data/logs/redis/keepalived-redis-state.log" echo "[stop]" >> $LOGFILE date >> $LOGFILE

附带一个备份脚本

1 2 3 4 5 6 7 8 9 10 11 12

#!/bin/bash #global dir variables dir="/data/server/redis/data/" backup_dir="/data/backups/redis/" #global backup file name file_name="redis-jzpush01-6359-dump.rdb" #section backup time section=`date +%y%m%d%H` #execute backup /data/server/redis/bin/redis-cli -p 6359 BGSAVE /bin/cp -f $dir/$file_name $backup_dir/$file_name.${section} /usr/bin/find $backup_dir -type f -ctime +2 | xargs -n 1 rm -f
