redis 集群

怎么关闭redis

如果是用apt-get或者yum install安装的redis，可以直接通过下面的命令停止/启动/重启redis

/etc/init.d/redis-server stop
/etc/init.d/redis-server start
/etc/init.d/redis-server restart

如果是通过源码安装的redis，则可以通过redis的客户端程序redis-cli``shutdown

redis-cli -h 127.0.0.1 -p 6379 shutdown

如果上述方式都没有成功停止redis，则可以使用终极武器 kill -9

怎么查看redis

ps -ef|grep redis

39.96.11.225:6379

分别修改端口为7001..7006

port 7001

修改绑定ip地址为本机实际网路ip地址

bind 127.0.0.1

bind 192.168.1.204

启用集群模式

cluster-enabled yes

nodes-7001.conf...nodes-7006.conf

cluster-config-file nodes-7001.conf
cluster-node-timeout 5000

超时时间appendonly yes

daemonize yes

后台运行

protected-mode no

非保护模式pidfile,分别修改为redis_7001.pid...7006.pid

/var/run/redis_7001.pid

需要把相对应的端口+10000也打开否则一直waiting
