redisnbsp;分布式,主从同步

redis和memcache比较像的,memcache可以实现服务器的集群,redis肯定也是可以的。下面在一台机,实现redis主从复制。
1,copy一下redis.conf,生成一个从机的配置
cp /usr/local/redis/redis.conf /usr/local/redis/redis_slave.conf
2,修改主服务器的配置redis.conf
bind 127.0.0.1
3,修改从服务器的配置redis_slave.conf
pidfile /usr/local/redis/var/redis_slave.pid
port 10002
bind 127.0.0.1
logfile /usr/local/redis/var/redis_slave.log
dbfilename dump_slave.rdb
slaveof 127.0.0.1 6379
4,启动主服务器,从服务器
redis-server /usr/local/redis/redis.conf
redis-server /usr/local/redis/redis_slave.conf
查看一下,redis.log文件会有以下内容
[3774] 27 Jun 12:53:32 * The server is now ready to accept connections on port 10002
[3774] 27 Jun 12:53:32 - 0 clients connected (0 slaves), 539568 bytes in use
[3774] 27 Jun 12:53:32 * Connecting to MASTER...
[3772] 27 Jun 12:53:32 - Accepted 127.0.0.1:33237
[3772] 27 Jun 12:53:32 * Slave ask for synchronization
[3772] 27 Jun 12:53:32 * Starting BGSAVE for SYNC
[3772] 27 Jun 12:53:32 * Background saving started by pid 3775
[3774] 27 Jun 12:53:32 * MASTER <-> SLAVE sync started: SYNC sent
[3775] 27 Jun 12:53:32 * DB saved on disk
[3772] 27 Jun 12:53:33 * Background saving terminated with success
[3772] 27 Jun 12:53:33 * Synchronization with slave succeeded
[3774] 27 Jun 12:53:33 * MASTER <-> SLAVE sync: receiving 333 bytes from master
[3774] 27 Jun 12:53:33 * MASTER <-> SLAVE sync: Loading DB in memory
[3774] 27 Jun 12:53:33 * MASTER <-> SLAVE sync: Finished with success
查看一下
root@ubuntu:/usr/local/redis# ps -e|grep redis
3774 ? 00:00:00 redis-server
4148 ? 00:00:00 redis-server
5,测试结果
查看复制打印?
 
root@ubuntu:/usr/local/redis# telnet 127.0.0.1 10002
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
get test
$9
[1,2,3,4]
缓存数据是放在6379这个端口的服务器上,代码执行后,登录到10002端口的slave服务器上也可以看到有数据,说明已经同步了。
我尝试了一下,redis的主主同步,但是没有成功,我看了一下log,以从服务器127.0.0.1 10002为master的时候,同时启动二个端口,怎么也连接不上127.0.0.1 6379是不支持呢?还是配置有问题,我在网上查了一下,没看到有人配置主主同步的。
