redis部署

下载软件

[root@localhost /]# wget http://download.redis.io/releases/redis-2.8.9.tar.gz

 

解压、编译、安装

[root@localhost /]# ll redis-2.8.9.tar.gz 
-rw-r--r--. 1 root root 1097369 Apr 22  2014 redis-2.8.9.tar.gz
[root@localhost /]# tar xf redis-2.8.9.tar.gz 
[root@localhost /]# cd redis-2.8.9
[root@localhost redis-2.8.9]# less README
[root@localhost redis-2.8.9]# make MALLOC=jemalloc
[root@localhost redis-2.8.9]# make PREFIX=/usr/local/redis install

 

在/usr/local/redis/bin/目录下生成5个可执行文件，分别是：

redis-benchmark  redis-check-dump  redis-server  redis-check-aof  redis-cli

 

他们的作用：

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

redis-check-aof：更新日志检查

redis-check-dump：用于本地数据库检查

 

配置环境变量

[root@localhost bin]# echo 'PATH=/usr/local/redis/bin/:$PATH' >> /etc/profile
[root@localhost bin]# tail -1 /etc/profile
PATH=/usr/local/redis/bin/:$PATH
[root@localhost bin]# . /etc/profile
[root@localhost bin]# which redis-server
/usr/local/redis/bin/redis-server
