Redis集群配置

1.进入Redis
cd /user/redis-3.2.5

2.进入Redis集群
redis-cli -c -h 192.168.0.242 -p 7001
redis-cli：表示客户端 -c:表示集群 -h:host,表示ip -p:表示端口

set test 222 放值
get test 取值
del test 删除

netstat -nlp |grep LISTEN //查看当前所有监听端口·
netstat -nlp |grep 80 //查看所有80端口使用情况·
netstat -an | grep 3306 //查看所有3306端口使用情况·

3.Redis出现问题时，重启步骤
（1）redis-cli -h 192.168.0.242 -p 7001 shutdown
redis-cli -h 192.168.0.242 -p 7002 shutdown
redis-cli -h 192.168.0.242 -p 7003 shutdown
redis-cli -h 192.168.0.242 -p 7004 shutdown
redis-cli -h 192.168.0.242 -p 7005 shutdown
redis-cli -h 192.168.0.242 -p 7006 shutdown
(2)查看监听的端口 是否被监听
lsof -i:7001
lsof -i:7002
lsof -i:7003
lsof -i:7004
lsof -i:7005
lsof -i:7006

(3) 删除文件 rm -rf nodes-700*
nodes-7001.conf
nodes-7002.conf
nodes-7003.conf
nodes-7004.conf
nodes-7005.conf
nodes-7006.conf

(4)启动
redis-server 7001.conf
redis-server 7002.conf
redis-server 7003.conf
redis-server 7004.conf

lsof -i:7002
lsof -i:7003
lsof -i:7004
