Question

$ riak start在启动30秒后崩溃。我在riak.conf中有以下（更改）设置：

search = on
storage_backend = leveldb
riak_control = on

crash.log包含以下内容：

Answer 1

确保Solr使用的端口可用。搜索的默认值为8093，JMX的默认值为8985。
调整系统以提高性能。关注Improving Performance for Linux。
在riak.conf中，增加JVM的堆大小，默认值1G通常是不够的。例如，search.solr.jvm_options=-d64 -Xms2g -Xmx4g -XX:+UseStringCache -XX:+UseCompressedOops（请参阅Search Settings）。
在慢速机器上，Solr可能需要更长时间才能启动。尝试增加search.solr.start_timeout。

Solr目录必须是可写的（通常为/var/lib/riak/data/yz*），并且使用兼容的JVM。

Answer 2

Riak 的内部 solr 使用localhost和127.0.0.1作为默认主机。所以它应该在/etc/hosts文件中定义：

127.0.0.1 localhost

仅供参考，如果您使用Windows，您的主机文件位置可能会有所不同。
