Redis安装
下载解压编译
$ wget http://download.redis.io/releases/redis-3.2.8.tar.gz $ tar -zxvf redis-3.2.8.tar.gz -C /usr/local $ cd /usr/local/redis-3.2.8 $ make
$ make install #将这些可执行程序复制到/usr/local/bin目录中以便以后执行程序时可以不用输入完整的路径
配置
复制默认配置到指定目录
cp redis.conf /usr/local/etc/
按需要修改参数
daemonize yes #---默认值no，该参数用于定制redis服务是否以守护模式运行。---
远程连接时需要修改以下参数
# bind 127.0.0.1 #绑定ip，默认是本机所有网络设备；protected-mode no #保护模式[无密码模式设置为no]
requirepass test #设置密码
启动
带配置启动
/usr/local/bin/redis-server /usr/local/etc/redis.conf
######查看进程
ps -ef | grep redis
开机启动，执行自带脚本
bash utils/install_server.sh
连接
/usr/bin/redis-cli
开户主从
复制配置文件，修改端口号，同时配置主库，然后启动服务即可。
可使用自带脚本，输入端口号，自动生成。然后配置主从。
