Linux下Redis的安装、配置操作说明(转)
Redis 是一个高性能的key-value数据库。 redis的出现,很大程度补偿了memcached这类keyvalue存储的不足,在部分场合可以对关系数据库起到很好的补充作用。它提供了Python,Ruby,Erlang,PHP客户端,使用很方便。
以下是安装测试步骤:
1,redis安装:
[html] view plaincopy
[root@localhost ~]# cd /usr/local/src/  
[root@localhost src]# wget http://redis.googlecode.com/files/redis-2.2.12.tar.gz  
[root@localhost src]# tar zxf redis-2.2.12.tar.gz  
[root@localhost src]# cd redis-2.2.12  
[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,需要复制下面的配置)  
[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,启动关闭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  
如果配置使用默认的127.0.0.1和6379端口,可执行命令时可省略以上参数。
4,测试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目录下执行文件功能说明:
redis-server:Redis服务器的daemon启动程序
redis-cli:Redis命令行操作工具。当然,你也可以用telnet根据其纯文本协议来操作
redis-benchmark:Redis性能测试工具,测试Redis在你的系统及你的配置下的读写性能
--------------------------满意的分割线-----------------------------------
实例:
1)登陆,输入数据:
[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 style="font-family: simsun; ">csdn</span>"  
redis 127.0.0.1:6379> quit  
2)查看redis统计信息:
[html] view plaincopy
[root@localhost ~]# /usr/local/redis/bin/redis-cli -h 127.0.0.1 -p 6379 info  
3)测试性能:
向redis服务器发送10个请求,每个请求附带50个并发客户端,-n 接请求数,-c 接并发数
[html] view plaincopy
[root@localhost ~]# /usr/local/redis/bin/redis-benchmark -h 127.0.0.1 -p 6379 -n 10 -c 50
