redis主从配置

9870780

一、准备工作

两个机器操作系统都是centos6.7，网卡eth0的ip分别为：

master  192.168.1.180
slave  192.168.1.181

二、基本操作（下面所有步骤都要在两个机器上操作 ）

1、设置hostname，分别为master和slave  

主上设置hostname

# hostname master              //临时生效

或者

# vim /etc/sysconfig/network   //永久生效
HOSTNAME=master

从上设置 hostname

# hostname slave               //临时生效

或者

# vim /etc/sysconfig/network   //永久生效
HOSTNAME=slave



2、关闭防火墙

主和从都清空iptables

# iptables -F

主和从都关闭 selinux

# setenforce 0

redis安装步骤

3.配置

由于我之前配置主的时候没有给redis设置密码，所以直接可以配置不用给主配置就可以连接。（如果你想设置也是可以的）

主配置

   
[iyunv@master etc]# vim redis.conf
daemonize yes
pidfile /usr/local/redis/var/redis.pid
port 6379
timeout 300
loglevel debug
logfile /usr/local/redis/var/redis.log
databases 16
save 900 1
save 300 10
save 60 10000
rdbcompression yes
dbfilename dump.rdb
dir /usr/local/redis/var/
appendonly no
appendfsync always
requirepass 123456 设置密码

从配置：在从上也同样添加上主的密码

   
[iyunv@slave etc]# vim redis.conf
daemonize yes
pidfile /usr/local/redis/var/redis.pid
port 6379
timeout 300
loglevel debug
logfile /usr/local/redis/var/redis.log
databases 16
save 900 1
save 300 10
save 60 10000
rdbcompression yes
dbfilename dump.rdb
dir /usr/local/redis/var/
appendonly no
appendfsync always
slaveof 192.168.1.180 7596   添加主的IP
masterauth 123456       添加主的密码


[iyunv@slave etc]# /etc/init.d/redis restart
停止 redis-server：                                        [确定]
启动 ：                                                    [确定]

查看有没有成功

在主

   
[iyunv@master etc]# /usr/local/redis/bin/redis-cli -a 123456
127.0.0.1:6379> keys *  查看所有
1) "set1"
2) "set2"
3) "key1"
4) "key2"
5) "hash1"
6) "list1"
7) "key3"
127.0.0.1:6379> set key6 guozhen 创建一个
OK
127.0.0.1:6379> keys *

5) "key2"
6) "hash1"
7) "list1"
8) "key3"
127.0.0.1:6379> get key6  查看内容
"guozhen"

看从

   
[iyunv@slave etc]# /usr/local/redis/bin/redis-cli
127.0.0.1:6379> keys *
1) "key1"
2) "key2"
3) "hash1"
4) "key6"
5) "list1"
6) "set1"
7) "set2"
8) "key3"
127.0.0.1:6379> get key6
"guozhen"

已经有了。说明我们配置成功了。
