Redis 是一個高性能的key-value數據庫。 redis的出現，很大程度補償了memcached這類keyvalue存儲的不足，在部分場合可以對關系數據庫起到很好的補充作用。它提供了Python，Ruby，Erlang，PHP客戶端，使用很方便。 以下是安裝測試步驟： 1，redis安裝（到這裡查看<a target=_blank href="https://code.google.com/archive/p/redis/downloads">https://code.google.com/archive/p/redis/downloads</a> 最新版）： [html] view plaincopy [root@localhost ~]# cd /usr/local/src/ [root@localhost src]# wgethttps://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/redis/redis-2.6.14.tar.gz --no-check-certificate [root@localhost src]# tar zxf redis-2.6.14.tar.gz [root@localhost src]# cd redis-2.6.14 [root@localhost redis-2.2.12]# make PREFIX=/usr/local/redis install 2，配置redis： [html] view plaincopy [root@localhost redis-2.2.12]# mkdir -p /usr/local/redis/etc [root@localhost redis-2.2.12]# mkdir -p /usr/local/redis/var [root@localhost redis-2.2.12]# cd /usr/local/redis/etc [root@localhost etc]# vi redis.conf（重新建立conf文件，需要復制下面的配置） [html] view plaincopy daemonize yes pidfile /usr/local/redis/redis.pid port 6379 bind 127.0.0.1 timeout 300 loglevel verbose logfile stdout databases 16 save 900 1 save 300 10 save 60 10000 rdbcompression yes dbfilename dump.rdb dir /usr/local/redis/var/ slave-serve-stale-data yes maxclients 12800 appendonly no appendfsync everysec no-appendfsync-on-rewrite no slowlog-log-slower-than 10000 slowlog-max-len 1024 vm-enabled no vm-swap-file /tmp/redis.swap vm-max-memory 0 vm-page-size 32 vm-pages 134217728 vm-max-threads 4 hash-max-zipmap-entries 512 hash-max-zipmap-value 64 list-max-ziplist-entries 512 list-max-ziplist-value 64 set-max-intset-entries 512 activerehashing yes 3，啟動關閉redis： [html] view plaincopy [root@localhost ~]# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf [root@localhost ~]# ps -ef|grep redis root 3891 1 0 18:11 ? 00:00:00 /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf [root@localhost redis-2.2.12]# /usr/local/redis/bin/redis-cli -h 127.0.0.1 -p 6379 shutdown 如果配置使用默認的127.0.0.1和6379端口,可執行命令時可省略以上參數。 4，測試redis： [html] view plaincopy [root@localhost ~]# telnet 127.0.0.1 6379 Trying 127.0.0.1... Connected to localhost (127.0.0.1). Escape character is '^]'. ^] telnet> quit Connection closed. 5，/usr/local/redis/bin目錄下執行文件功能說明： redis-server：Redis服務器的daemon啟動程序 redis-cli：Redis命令行操作工具。當然，你也可以用telnet根據其純文本協議來操作 redis-benchmark：Redis性能測試工具，測試Redis在你的系統及你的配置下的讀寫性能 --------------------------滿意的分割線----------------------------------- 實例： 1）登陸，輸入數據： [html] view plaincopy [root@localhost ~]# /usr/local/redis/bin/redis-cli -h 127.0.0.1 -p 6379 redis 127.0.0.1:6379> set name csdn OK redis 127.0.0.1:6379> get name "<span >csdn</span>" redis 127.0.0.1:6379> quit 2）查看redis統計信息： [html] view plaincopy [root@localhost ~]# /usr/local/redis/bin/redis-cli -h 127.0.0.1 -p 6379 info 3）測試性能： 向redis服務器發送10個請求，每個請求附帶50個並發客戶端，-n 接請求數，-c 接並發數 [html] view plaincopy [root@localhost ~]# /usr/local/redis/bin/redis-benchmark -h 127.0.0.1 -p 6379 -n 10 -c 50
