我的Java版本Solr不'；我不能自动启动,solr,Solr,我的Java版本 solr-5.4.0 version 我完成了所有步骤，最终得到了这个错误 java -version java version "1.7.0_91" OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.14.04.1) OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode) 找到1个Solr节点： sudo service solr sta

更新：我刚刚用32位Ubuntu 14.04虚拟机（Vagrantfile中的
Ubuntu/trusty32Vagrant.configure(2) do |config|
config.vm.box = "ubuntu/trusty64"
config.vm.network "private_network", ip: "192.168.33.10"
config.vm.provider "virtualbox" do |vb|
vb.memory = "1024"

这要归功于此。您是否尝试删除该pid文件？我会确保停止Solr，删除pid，然后再次尝试启动。如何删除pid？删除
