redis伪集群脚本

 

 

 

#/bin/bash
#set -e

#安装redis伪集群脚本,先把redis-5.0.4.tar.gz redis-3.2.2.gem及启动脚本放在/data1/redis-cluster目录下，然后执行该脚本即可 
#!/bin/bash
set -e
#获取redis本机ip
ip=`hostname -I`
workspace=/data1/redis-cluster  #根据需求自定义  想在哪个目录安装就写哪个目录
if [ ! -d $workspace ];then
        mkdir -p $workspace

启动脚本

单实例设置自启动脚本

1、复制redis启动脚本

redis启动脚本一般在redis根目录的utils,如果不知道路径,可以先查看路径

[root@slj-redis data1]#  find / -name redis_init_script

/data1/redis-cluster/redis-4.0.9/utils/redis_init_script

 

复制启动脚本到/etc/init.d/redis文件中

cp /data1/redis-cluster/redis-4.0.9/utils/redis_init_script /etc/init.d/redis-alone

 

2、更改redis-alone脚本

 

首先添加如下俩行

# chkconfig: 2345 90 10

# description: Redis is a persistent key-value database

 

其次更改EXEC   CLIEXEC  CONF 为实际所安装目录即可

REDISPORT=6379

EXEC=/data1/redis-alone/bin/redis-server

CLIEXEC=/data1/redis-alone/bin/redis-cli

 

PIDFILE=/var/run/redis_${REDISPORT}.pid

CONF="/data1/redis-alone/redis.conf"

 

 

chkconfig redis-alone on

集群设置自启动

 

 

先写好集群启动脚本

[root@slj-redis redis-cluster]# cat all-start.sh

cd /data1/redis-cluster/redis-01 

./redis-server redis.conf 

 

cd /data1/redis-cluster/redis-02

./redis-server redis.conf

 

cd /data1/redis-cluster/redis-03

./redis-server redis.conf

 

cd /data1/redis-cluster/redis-04

./redis-server redis.conf

 

cd /data1/redis-cluster/redis-05

./redis-server redis.conf

 

cd /data1/redis-cluster/redis-06

./redis-server redis.conf

 

 

关闭脚本

[root@slj-redis redis-cluster]# vim all-stop.sh

 

redis-cli -h 10.253.0.1 -p 7001  shutdown

redis-cli -h 10.253.0.1 -p 7002  shutdown

redis-cli -h 10.253.0.1 -p 7003  shutdown

redis-cli -h 10.253.0.1 -p 7004  shutdown

redis-cli -h 10.253.0.1 -p 7005  shutdown

redis-cli -h 10.253.0.1 -p 7006  shutdown

 

 

 

[root@slj-redis init.d]# vim redis-cluster

#!/bin/sh

#

# chkconfig: 2345 70 20

# description: Redis-cluster autostart

. /etc/init.d/functions

 

 

case "$1" in

    start)

        /bin/bash /data1/redis-cluster/all-start.sh

        ;;

    stop)

        /bin/bash /data1/redis-cluster/all-stop.sh

        ;;

    *)

        echo "Usage: $0 (start|stop)"

        ;;

esac

 

 

chkconfig redis-cluster on

 

 

批量删除key

redis-cli -h <host> -a <password> keys "<key>" | xargs redis-cli -h <host> -a <password> del
