### 3./usr/local/redis/bin目录
redis-server #redis服务器的daemon启动程序
redis-cli #redis命令行操作工具。也可以用telnet根据其纯文本协议来操作。
redis-benchmark #redis性能测试工具,检测redis在系统以及配置下的读写性能
redis-stat #redis状态检测工具,可以检测redis当前状态参数以及延迟状况
#### 4.启动:
/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
#### 5.检测:
ps -ef | grep redis
redis-cli ping
#### 6.关闭:
手动持久化内存数据至磁盘(注意,持久化时,可能需要额外的maxmemory,即:若配置了8G,则再需要8G内存才能完成数据的持久化)
redis-cli -h 127.0.0.1 -p 6379 bgsave #默认保存到配置文件中的‘dir’下。
/usr/local/redis/bin/redis-cli shutdown #默认关闭6379端口的redis进程,关闭时,会使用bgsave持久化数据到磁盘中。
关闭指定端口的redis-server
redis-cli -p 6379 shutdown
#### 7.保存/备份
数据备份可以通过定期备份该文件实现。
因为redis是异步写入磁盘的,如果要让内存中的数据马上写入硬盘可以执行如下命令:
redis-cli save 或者 redis-cli -p 6380 save(指定端口)
注意,以上部署操作需要具备一定的权限,比如复制和设定内核参数等。
执行redis-benchmark命令时也会将内存数据写入硬盘。
#### 8.连接
redis-cli -a passwd
