Redis安装与主从配置

22312312

配置环境：
      Master服务器 : 192.168.189.129:44444
      Slave服务器 : 192.168.189.131:44444


一：下载安装redis软件包，并解压

1 2 3 4

# cd /usr/local/src # wget http://redis.googlecode.com/files/redis-2.6.4.tar.gz   # tar -zxvf redis-2.6.4.tar.gz # cd redis-2.6.4

二：安装
redis软件不依赖其他的库，也不需要额外的编译参数，可直接make install进行安装

1	# make install

三：创建所需目录与文件，便于管理

1 2 3 4 5 6

# mkdir -p /usr/local/redis/bin # mkdir -p /usr/local/redis/etc # mkdir -p /usr/local/redis/var # mkdir -p /usr/local/redis/data # cp redis.conf /usr/local/redis/etc/ # cp /usr/local/bin/redis-* /usr/local/redis/bin

四：配置redis.conf文件如下
Master服务器端:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

# grep -v '^#' redis.conf |grep -v '^$'                      daemonize yes pidfile /usr/local/redis/var/redis.pid #定义端口 port 44444 #绑定IP bind 192.168.189.129 timeout 300 loglevel notice #指定日志目录 logfile /usr/local/redis/var/redis.log databases 16 #配置持久化（rdb模式） save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes #定义数据文件和目录 dbfilename master.rdb dir /usr/local/redis/data slave-serve-stale-data yes slave-read-only yes slave-priority 100 appendonly no appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-entries 512 list-max-ziplist-value 64 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb60 client-output-buffer-limit pubsub 32mb 8mb 60

Slave服务器端：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

# grep -v '^#' redis.conf |grep -v '^$' daemonize yes pidfile /usr/local/redis/var/redis.pid port 44444 bind 192.168.189.131 timeout 300 loglevel notice logfile /usr/local/redis/var/redis.log databases 16 save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename slave.rdb dir /usr/local/redis/data slaveof 192.168.189.129 44444         ------指定master的地址 slave-serve-stale-data yes slave-read-only yes slave-priority 100 appendonly no appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-entries 512 list-max-ziplist-value 64 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb60 client-output-buffer-limit pubsub 32mb 8mb 60

五：依次开启主从redis，并测试

1 2 3 4

Master: # /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf Slave: # /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

使用客户端连接主redis，并进行一些简单操作
# /usr/local/redis/bin/redis-cli -h 192.168.189.129 -p 44444

连接从redis，查看数据是否同步
# /usr/local/redis/bin/redis-cli -h 192.168.189.131 -p 44444

从上可看到数据已同步，证明redis主从配置生效


注：由于在配置文件中配置了slave-read-only yes,因此从节点处于只读状态，无法对数据库进行操作和更改。
