导语:
为了保证安全性,redis在生产环境中一般都会设置登录密码,今天我就来为大家介绍一下如何设置登录密码。
(学习视频分享:redis视频教程)
修改redis.conf
RT,打开redis.conf文件,搜索requirepass关键字,如下图:

关注标记的那一行,#requirepass foobared。设置密码的方法就是去掉注释的#,把foobared替换成自己的密码即可,例如将密码设置为123456:

修改完成后重启redis,再次通过redis客户端redis-cli登录并操作可以发现会报一个身份认证错误:

这就说明我们已经成功的设置了密码,所以通过客户端连接的话必须加上密码参数才能正常连接:

如上图所示,加了-a参数之后即可正常连接并操作redis。
jedis设置密码
当我们用Java客户端连接redis时会遇到同样的问题,下面看一段简单的jedis连接redis的测试代码:
package com.firstelite.test;
import org.junit.Test;
import redis.clients.jedis.Jedis;
public class Test4Jedis {
@Test
public void testTwo() {
Jedis jedis = new Jedis("192.168.145.10");
System.out.println("Connection to server sucessfully");
// 查看服务是否运行
System.out.println("Server is running: " + jedis.ping());
}
}非常简单,仅仅是测试一下Jedis是否连通redis服务器,运行junit后我们发现报异常了:
redis.clients.jedis.exceptions.JedisDataException: NOAUTH Authentication required.

at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)显而易见,由于我们设置了密码但在这里又没有指定密码,所以报了和刚才相同的错误,那么如何指定密码呢?很简单,Jedis的父类BinaryJedis提供了这样一样方法:
public String auth(final String password) {
checkIsInMulti();
client.auth(password);
return client.getStatusCodeReply();
}所以在创建了Jedis的实例后再加上一行jedis.auth("123456"); 即可,最后看一下运行结果:

spring-data-redis设置密码
通常情况下在实际的java项目中我们会选择Spring提供的spring-data-redis来操作redis,spring的封装可以给我们提供很多便捷之处。那么spring-data-redis又是如何设置密码的呢?首先定义一个redis.properties配置文件,定义一组redis属性供spring加载使用,其中就包含密码(redis.password):
# Redis settings redis.host=192.168.145.10 redis.port=6379 redis.password=123456 redis.timeout=100000 redis.maxTotal=300 redis.maxIdle=100 redis.maxWaitMillis=1000 redis.testOnBorrow=true
然后在由Spring封装的JedisConnectionFactory中来设置密码属性即可,下面是完整redis配置:
<!-- redis配置 -->
<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxIdle" value="${redis.maxIdle}" />
<property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
<property name="testOnBorrow" value="${redis.testOnBorrow}" />
</bean>
<bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
p:host-name="${redis.host}" p:port="${redis.port}"
p:password="${redis.password}" p:pool-config-ref="poolConfig" />
<bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
<property name="connectionFactory" ref="connectionFactory" />
</bean>相关推荐:redis数据库教程
