防火墙和selinux需关闭，不然会影响主从间的连接。
1. 下载并解压 (主从)
# wget http://download.redis.io/releases/redis-5.0.2.tar.gz
# tar -zxvf redis-5.0.2.tar.gz -C /usr/local/src ##解压到/usr/local/src目录下
# yum install -y gcc-c++ tcl ##安装依赖包
2. 编译并安装 (主从)
# cd /usr/local/src/redis-5.0.2/
# make install PREFIX=/usr/local/redis ##编译安装
# cd /usr/local/redis/bin/
# cp redis-cli redis-server /usr/sbin/ ##方便直接执行命令
3. 建立并修改配置文件
主从都需操作
# cp /usr/local/src/redis-5.0.2/redis.conf /usr/local/redis/
主redis服务器的redis.conf配置:
# vi /usr/local/redis/redis.conf ##修改以下配置
# daemonize no 改为 daemonize yes
# bind 127.0.0.1 改为 bind 0.0.0.0
# logfile "" 改为 logfile /var/log/redis_6379.log
# # requirepass foobared 改为 requirepass 123456
从redis服务器的redis.conf配置:
# vi /usr/local/redis/redis.conf ##修改以下配置
# daemonize no 改为 daemonize yes
# bind 127.0.0.1 改为 bind 0.0.0.0
# logfile "" 改为 logfile /var/log/redis_6379.log
# # requirepass foobared 改为 requirepass 123456
# masterauth <master-password> 改为 masterauth 123456
# 添加 slaveof 192.168.88.40 6379
4. 启动Redis服务 (主从)
# redis-server /usr/local/redis/redis.conf
# netstat -lnt ##查看6379端口开启
