先做 Redis 集群,然后写个 Spring Data Redis 测试是否可以正常使用该集群
.msi 后缀的文件进行安装,此安装包自带安装 Windows 服务redis.windows.confinfo
server 部分记录了 Redis 服务器的信息,它包含以下域:
redis_version : Redis 服务器版本
redis_git_sha1 : Git SHA1
redis_git_dirty : Git dirty flag
os : Redis 服务器的宿主操作系统
arch_bits : 架构(32 或 64 位)
multiplexing_api : Redis 所使用的事件处理机制
gcc_version : 编译 Redis 时所使用的 GCC 版本
process_id : 服务器进程的 PID
run_id : Redis 服务器的随机标识符(用于 Sentinel 和集群)
tcp_port : TCP/IP 监听端口
uptime_in_seconds : 自 Redis 服务器启动以来,经过的秒数
uptime_in_days : 自 Redis 服务器启动以来,经过的天数
lru_clock : 以分钟为单位进行自增的时钟,用于 LRU 管理
clients 部分记录了已连接客户端的信息,它包含以下域:
connected_clients : 已连接客户端的数量(不包括通过从属服务器连接的客户端)
client_longest_output_list : 当前连接的客户端当中,最长的输出列表
client_longest_input_buf : 当前连接的客户端当中,最大输入缓存
blocked_clients : 正在等待阻塞命令(BLPOP、BRPOP、BRPOPLPUSH)的客户端的数量
memory 部分记录了服务器的内存信息,它包含以下域:
used_memory : 由 Redis 分配器分配的内存总量,以字节(byte)为单位
used_memory_human : 以人类可读的格式返回 Redis 分配的内存总量
used_memory_rss : 从操作系统的角度,返回 Redis 已分配的内存总量(俗称常驻集大小)。这个值和 top 、 ps 等命令的输出一致。
used_memory_peak : Redis 的内存消耗峰值(以字节为单位)
used_memory_peak_human : 以人类可读的格式返回 Redis 的内存消耗峰值
used_memory_lua : Lua 引擎所使用的内存大小(以字节为单位)
mem_fragmentation_ratio : used_memory_rss 和 used_memory 之间的比率
mem_allocator : 在编译时指定的, Redis 所使用的内存分配器。可以是 libc 、 jemalloc 或者 tcmalloc 。
used_memory_rss_human:系统给redis分配的内存(即常驻内存)
used_memory_peak_human : Redis 的内存消耗峰值
used_memory_lua_human : 系统内存大小
expired_keys : 过期的的键数量
evicted_keys : 因为最大内存容量限制而被驱逐(evict)的键数量
used_cpu_sys_children : Redis 后台进程在 内核态 消耗的 CPU
used_cpu_user_children : Redis 后台进程在 用户态 消耗的 CPU
