Redis主从配置

1.解压redis

tar -xvf redis-3.2.11.tar.gz

cd redis-3.2.11

make

“如果make有报错，则执行，没有报错就不需要 make MALLOC=libc  ”

配置redis主从

主：0.0.0.0:6379

从：0.0.0.0:6380

从：0.0.0.0:6381

主Redis配置

cp -r redis-3.2.11 /usr/local/redis-1

修改redis.conf文件

Cd /usr/local/redis-1

Vim redis.conf

 

 

redis.conf

#下面是redis.conf的主 要配置参数的意义：

#daemonize：是否以后台daemon方式运行

#pidfile：pid文件位置

#port：监听的端口号

#timeout：请求超时时间

#loglevel：log信息级别

#logfile：log文件位置

#databases：开启数据库的数量

#save * *：保存快照的频率，第一个*表示多长时间，第三个*表示执行多少次写操作。在一定时间内执行一定数量的写操作时，自动保存快照。可设置多个条件。

#rdbcompression：是否使用压缩

#dbfilename：数据快照文件名（只是文件名，不包括目录）

#dir：数据快照的保存目录（这个是目录）

#appendonly：是否开启appendonlylog，开启的话每次写操作会记一条log，这会提高数据抗风险能力，但影响效率。

#appendfsync：appendonlylog如何同步到磁盘（三个选项，分别是每次写都强制调用fsync、每秒启用一次fsync、不调用fsyn

c等待系统自己同步）
