Redis是一个开源的使用ANSI C语言编写、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库,并提供多种语言的API。从2010年3月15日起,Redis的开发工作由VMware主持。
如何安装Redis?
Redis的官方下载站是http://redis.io/download,可以去上面下载最新的安装程序下来,我写此文章时的的稳定版本是2.2.12。
怎么安装 Redis数据库呢?下面将介绍Linux版本的安装方法:
步骤一: 下载Redis
下载安装包:wget http://redis.googlecode.com/files/redis-2.2.12.tar.gz

[root@localhost 4setup]#
步骤二: 编译源程序

[root@localhost 4setup]# ll

[root@localhost 4setup]# tar xzf redis - 2.2 . 12 .tar.gz
[root@localhost 4setup]# cd redis - 2.2 . 12
[root@localhost redis - 2.2 . 12 ]# make
cd src && make all
make[ 1 ]: Entering directory ` / root / 4setup / redis - 2.2 . 12 / src '
总计 29168
- rw - r -- r -- 1 root root 455240 2011 - 07 - 22 redis - 2.2 . 12 .tar.gz
[root@localhost 4setup]# tar xzf redis - 2.2 . 12 .tar.gz
[root@localhost 4setup]# cd redis - 2.2 . 12
[root@localhost redis - 2.2 . 12 ]# make
cd src && make all
make[ 1 ]: Entering directory ` / root / 4setup / redis - 2.2 . 12 / src '
步骤三: 启动Redis服务
<!--<br /><br />Code highlighting produced by Actipro CodeHighlighter (freeware)<br />http://www.CodeHighlighter.com/<br /><br />-->
src
/
redis
-
server
[root@localhost redis - 2.2 . 12 ]# src / redis - server
[ 6246 ] 05 Aug 19 : 17 : 22 # Warning: no config file specified, using the default config. In order to specify a config file use ' redis-server /path/to/redis.conf'
[ 6246 ] 05 Aug 19 : 17 : 22 * Server started, Redis version 2.2 . 12
[ 6246 ] 05 Aug 19 : 17 : 22 # WARNING overcommit_memory is set to 0 ! Background save may fail under low memory condition. To fix this issue add ' vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
[ 6246 ] 05 Aug 19 : 17 : 22 * The server is now ready to accept connections on port 6379
[ 6246 ] 05 Aug 19 : 17 : 22 - 0 clients connected ( 0 slaves), 539544 bytes in use
[root@localhost redis - 2.2 . 12 ]# src / redis - server
[ 6246 ] 05 Aug 19 : 17 : 22 # Warning: no config file specified, using the default config. In order to specify a config file use ' redis-server /path/to/redis.conf'
[ 6246 ] 05 Aug 19 : 17 : 22 * Server started, Redis version 2.2 . 12
[ 6246 ] 05 Aug 19 : 17 : 22 # WARNING overcommit_memory is set to 0 ! Background save may fail under low memory condition. To fix this issue add ' vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
[ 6246 ] 05 Aug 19 : 17 : 22 * The server is now ready to accept connections on port 6379
[ 6246 ] 05 Aug 19 : 17 : 22 - 0 clients connected ( 0 slaves), 539544 bytes in use
Redis 服务端的默认连接端口是 6379。
步骤四: 将Redis作为 Linux 服务随机启动
vi /etc/rc.local, 使用vi编辑器打开随机启动配置文件,并在其中加入下面一行代码。
<!--<br /><br />Code highlighting produced by Actipro CodeHighlighter (freeware)<br />http://www.CodeHighlighter.com/<br /><br />-->
/
root
/
4setup
/
redis
-
2.2
.
12
/
src
/
redis
-
server
步骤五: 客户端连接验证
新打开一个Session输入:src/redis-cli,如果出现下面提示,那么您就可以开始Redis之旅了。
<!--<br /><br />Code highlighting produced by Actipro CodeHighlighter (freeware)<br />http://www.CodeHighlighter.com/<br /><br />-->
[root@localhost redis
-
2.2
.
12
]# src
/
redis
-
cli
redis 127.0 . 0.1 : 6379 >
redis 127.0 . 0.1 : 6379 >
步骤六: 查看Redis日志
查看服务器端session,即可对Redis的运行状况进行查看或分析了。

以上的几个步骤就OK了!!这样一个简单的Redis数据库就可以畅通无阻地运行起来了。
步骤七: 停止Redis实例
最简单的方法是在启动实例的session中,直接使用Control-C来将实例停止。
我们还可以用客户端来停止服务,如可以用shutdown来停止Redis实例, 具体如下:

cli shutdown
