Redis主从配置详细过程
Redis主从架构主要是写服务由Redis主服务器来完成，Redis从服务器可以为客户端提供只读操作的服务，可以分载Redis主服务器的读操作压力，系统的伸缩性还是得到了很大的提高。Redis主服务器可以将数据保存操作交给Redis从服务器完成，从而避免了在Redis主服务器中要有独立的进程来完成此操作。下面雷雪松记录了Linux下Redis主从配置的详细过程。
创建Redis相关目录
1 2 | [root@Redis ~]# mkdir -p /usr/local/redis/{etc,bin,var} [root@Redis ~]# mkdir -p /redisDb/logs/ /redisDb/data |
编译安装Redis
1 2 3 4 5 6 | [root@Redis ~]# tar -xvzf redis-2.4.13.tar.gz [root@Redis ~]# cd redis-2.4.13 [root@Redis ~]# make [root@Redis ~]# cd src && cp redis-server redis-cli redis-benchmark /usr/local/redis/bin [root@Redis ~]# echo "vm.overcommit_memory=1" >> /etc/sysctl.conf [root@Redis ~]# /sbin/sysctl -p |

启动Redis服务：
1 | [root@Redis ~]# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf |
Redis主服务器上执行：
1 | [root@Redis ~]# /usr/local/redis/bin/redis-cli -h 192.168.1.112 -a redis123 set test 123456 |
Redis从服务器上执行：
1 | [root@Redis ~]# /usr/local/redis/bin/redis-cli -h 192.168.1.118 get test |
测试Redis是否已启动
1 | [root@Redis ~]# /usr/local/redis/bin/redis-cli ping |
性能Redis测试
1 | [root@Redis ~]# /usr/local/redis/bin/redis-benchmark |
关闭Redis服务
1 | [root@Redis ~]# /usr/local/redis/bin/redis-cli -p 6379 shutdown |
强制刷新数据到磁盘【Redis默认是异步写入磁盘的】
1 | [root@Redis ~]# /usr/local/redis/bin/redis-cli -p 6379 save |
