Linux Redis環境搭建

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
