Linux下Redis的安装、配置操作说明

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:

1redis安装:

[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

[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)
复制代码
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
复制代码
3,启动关闭redis
[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

复制代码
[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.
复制代码

5/usr/local/redis/bin目录下执行文件功能说明:

redis-serverRedis服务器的daemon启动程序

redis-cliRedis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-benchmarkRedis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:

[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
"csdn"
redis 127.0.0.1:6379> quit

2)查看redis统计信息:

[root@localhost ~]# /usr/local/redis/bin/redis-cli -h 127.0.0.1 -p 6379 info

3)测试性能:

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

[root@localhost ~]# /usr/local/redis/bin/redis-benchmark -h 127.0.0.1 -p 6379 -n 10 -c 50
