Linux系統(tǒng)下的redis的主從配置方法非常簡單，下面給大家分享一下redis的主從配置方法具體的操作步驟

環(huán)境介紹：

OS：oracle linux 5.6

redis:redis-2.6.8

master rac1 192.168.2.101

slave rac2 192.168.2.102

下載地址：

http://redis.googlecode.com/files/redis-2.6.8.tar.gz

安裝配置主從redis

1. 主節(jié)點(diǎn)配置

[root@rac1 opt] tar zxvf redis-2.6.8.tar.gz
[root@rac1 opt] cd redis-2.6.8
[root@rac1 redis-2.6.8]# make
[root@rac1 redis-2.6.8]# cp src/redis-server /usr/local/bin/
[root@rac1 redis-2.6.8]# cp redis.conf /etc/redis_master.conf
[root@rac1 redis-2.6.8]# cat /etc/redis_master.conf 
# If port 0 is specified Redis will not listen on a TCP socket.

port 6379 #此端口是redis默認(rèn)的，可以不改

復(fù)制軟件到從節(jié)點(diǎn)

[root@rac1 opt]# scp -r redis-2.6.8 rac2:/opt

2. 從節(jié)點(diǎn)配置

[root@rac2 redis-2.6.8]# cp src/redis-server /usr/local/bin/
[root@rac2 redis-2.6.8]# cp redis.conf /etc/redis_slave.conf
# If port 0 is specified Redis will not listen on a TCP socket.

port 6389 #修改為slave節(jié)點(diǎn)的自定義端口

# slaveof <masterip> <masterport>
slaveof 192.168.2.101 6379

此步最關(guān)鍵，添加上master的IP或主機(jī)及端口號(hào)

3. 啟動(dòng)redis服務(wù)

啟動(dòng)master節(jié)點(diǎn)

[root@rac1 ~]# redis-server /etc/redis_master.conf > redis_master.log 2>&1 &

&可以使命令在后臺(tái)的執(zhí)行，不影響屏幕使用。

4. 驗(yàn)證主從復(fù)制

master節(jié)點(diǎn)數(shù)據(jù)輸入

[root@rac1 ~]# telnet 192.168.2.101 6379
Trying 192.168.2.101...
Connected to rac1.localdomain (192.168.2.101).
Escape character is '^]'.
rpush data 1

rpush data 1
:2
lrange data 0 -1

slave節(jié)點(diǎn)驗(yàn)證

[root@rac1 ~]# telnet 192.168.2.102 6389
Trying 192.168.2.102...

好了，到此主從redis已經(jīng)配置完成并成功運(yùn)行了，Linux系統(tǒng)下的redis主從配置方法操作很簡單只要接步驟認(rèn)真配置基本都可以配置成功
