代码部分
package com.test.jedis;
import org.junit.Test;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
public class JedisTest {
@Test
public void testJedis() {
Jedis jedis = new Jedis("192.168.1.107", 6379);
jedis.set("name", "admin");
String name = jedis.get("name");
System.out.println("name:" + name);
jedis.close();
}
@Test
public void testJedisPool() {//使用连接池方式
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxIdle(23);
config.setMaxTotal(100);
JedisPool pool = new JedisPool(config, "192.168.1.107", 6379);
Jedis jedis = null;
try {
jedis = pool.getResource();
jedis.set("name", "wakaka");
String name = jedis.get("name");
System.out.println("#name:" + name);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (jedis != null) {
jedis.close();
}
if (pool != null) {
pool.close();
}
}
}
}
首次运行报错：connectTimeOut连接数据库超时，检查了一下，虚拟机中centos7的Redis的端口被防火墙过滤了。
解决方法：
- 将6379端口加入白名单
vi /etc/sysconfig/iptables
# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
6379端口这一行是新增的内容，即
-A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT
重启服务
service iptables restart-
Windows的cmd打开,测试192.168.1.107的6379端口
telnet 192.168.1.107 6379
如果显示连接成功，--->END如果显示连接失败，请继续往下看步骤4
检查192.168.1.107中Redis的配置文件
vi redis.conf
找到bind 127.0.0.1修改为192.168.1.107。
再次回到步骤3，测试成功-->END
正在学习Redis，记作笔记，有误请指出。谢谢
