centos下使用redis报错cant resolve localhost address之解决
摘要:今天在centos下部署使用redis报了如下错误:redis.clients.jedis.HostAndPort.getLocalHostQuietly cant resolve localhost address。java.net。经查是主机名导致的,在/etc/hosts中添加本机主机名后,问题解决。
今天在centos下部署使用redis报了如下错误:
22-Sep-2022 09:21:05.477 SEVERE [main] redis.clients.jedis.HostAndPort.getLocalHostQuietly cant resolve localhost address java.net.UnknownHostException: host-192-168-1-100: host-192-168-1-100: Name or service not known at java.net.InetAddress.getLocalHost(InetAddress.java:1506) at redis.clients.jedis.HostAndPort.getLocalHostQuietly(HostAndPort.java:105) at redis.clients.jedis.HostAndPort.<clinit>(HostAndPort.java:12) at redis.clients.jedis.JedisFactory.<init>(JedisFactory.java:37) at redis.clients.jedis.JedisPool.<init>(JedisPool.java:185) at redis.clients.jedis.JedisPool.<init>(JedisPool.java:162) at redis.clients.jedis.JedisPool.<init>(JedisPool.java:92)
经查,是主机名导致的。下面是解决办法:
查看主机名 #hostname 查看上述主机名是否包含在第一行内容中,如果没有添加上即可 #cat /etc/hosts
其实从上面报错中能看出一些关键信息:主机名是host-192-168-1-100,但是该名称没有包含在/etc/hosts文件中。添加后再试,问题解决。
