redis3.2 学习记录 springmvc +jredis +redis 整合
来源：互联网 发布：软件详细设计工具 编辑：程序博客网 时间：2024/05/17 20:27
首先linux安装redis
1、官网下载
2、tar -zxvf xxxxx.tar.gz
3、阅读readme文件，编译安装 进入目录 make , make test (可选) ， make install
安装过程比较简单，安装过程可能会提示缺少相关的库，去网上找，然后安装就行了
redis 使用学习记录
============================
重启服务
pkill redis-server
然后再启动服务和客户端连接,注意：更改了redis的配置文件，启动时一定要加载redis.conf 否则更改的配置不生效
不加载配置文件启动方式:
/home/data/redis/src/redis-server
加载配置文件启动方式:
/home/data/redis/src/redis-server /home/data/redis/redis.conf &
或者
进到redis的安装目录下的src文件下,运行命令：
不加载配置文件启动方式:
./redis-server &
加载配置文件启动方式:
./redis-server /home/data/redis/redis.conf & (&符号代表交给后台运行)
打开redid自带的客户端
/home/data/redis/bin/redis-cli （打开redid自带的客户端）
或者
进到redis的安装目录下的src文件下,运行命令：
./redis-cli
有设置了认证密码的：使用 auth命令 进行授权认证
auth mypassword
直接使用密码打开redis 客户端：
./redis-cli -a mypassword
退出：exit
表明服务已启动。
$ redis-cli ping
PONG
本地 6379 端口号已被 redis 监听。
$ netstat -an | grep 6379
tcp 0 0 127.0.0.1:6379 0.0.0.0:* LISTEN
redis.conf配置文件：配置说明
1、requirepass mypassword
2、bind 绑定本机的ip
bind 192.168.1.102 (代表同一局域网都可以访问，注：192.168.1.102 是本机的局域网IP，并不是其他机器的IP)
bind 127.0.0.1 192.168.1.200（可以你绑定多个本机iP地址）
整合springmvc 简单例子
