redis安装和java web如何结合redis？

</pre><pre name="code" class="java">java web如何结合redis？

**********第一步:安装redis到linux服务器.
因为redis依赖tcl,所以首先需要安装tcl.
将tcl8.5.10-src.tar.gz拷贝到/opt/tcl目录下执行如下指令:
iluckysi@ILUCKYSI-PC:~/tcl# tar -zxvf tcl8.5.10-src.tar.gz 
iluckysi@ILUCKYSI-PC:~/tcl# cd tcl8.5.10/unix/
iluckysi@ILUCKYSI-PC:~/tcl/tcl8.5.10/unix# ./configure
iluckysi@ILUCKYSI-PC:~/tcl/tcl8.5.10/unix# make
iluckysi@ILUCKYSI-PC:~/tcl/tcl8.5.10/unix# make install

将redis-3.0.1.tar.gz拷贝到/opt/redis目录下执行如下指令:
iluckysi@ILUCKYSI-PC:~/redis# tar -zxvf redis-3.0.1.tar.gz 
iluckysi@ILUCKYSI-PC:~/redis# cd redis-3.0.1
iluckysi@ILUCKYSI-PC:~/redis/redis-3.0.1# make 
iluckysi@ILUCKYSI-PC:~/redis/redis-3.0.1# make test
iluckysi@ILUCKYSI-PC:~/redis/redis-3.0.1# make install


**********第二步:启动redis.
注意:默认情况下redis编译时会将redis-server等命令拷贝至/usr/local/bin目录下.
同时,redis启动默认是在前台,可以通过修改如下配置文件将redis启动模式改为后台.
iluckysi@ILUCKYSI-PC:~/redis/redis-3.0.1# vi redis.conf 
将daemonize no修改为daemonize yes表示启动后在后台运行.
启动redis需要指定配置文件,如下:
iluckysi@ILUCKYSI-PC:/usr/local/bin# ./redis-server /opt/redis/redis-3.0.1/redis.conf 
iluckysi@ILUCKYSI-PC:/usr/local/bin# ps -ef | grep redis
root      5968     1  0 10:41 ?        00:00:00 ./redis-server *:6379                           
root      5972  5820  0 10:41 pts/1    00:00:00 grep redis
iluckysi@ILUCKYSI-PC:/usr/local/bin# 


**********第三步:停止redis.
iluckysi@ILUCKYSI-PC:/usr/local/bin# redis-cli -h 192.168.1.3 -p 6379 shutdown
iluckysi@ILUCKYSI-PC:/usr/local/bin# ps -ef | grep redis
root      4799  4658  0 19:53 pts/1    00:00:00 grep redis


**********第四步:连接redis.
iluckysi@ILUCKYSI-PC:/usr/local/bin# redis-cli -h 192.168.1.3 -p 6379
192.168.1.3:6379> set username IS
OK
192.168.1.3:6379> get username
"IS"
192.168.1.3:6379> 

**********第五步:创建java项目,引入jedis2.7.2.jar.
马上开启你的redis学习之旅吧！
public class Test {
	private static Jedis jedis = null;
	public static void main(String[] args) {
		jedis = new Jedis("192.168.1.3");  
		jedis.set("username", "IluckySi");  
		System.out.println(jedis.get("username")); //IluckySi  
	}
}
