在 Debian 8 上安装 Solr 5

Question

我按照 https://ctors.net/2015/07/14/solr5_java8_debian8 上的说明进行操作。

作为 root

首先我安装了Java8:

mkdir -p /opt/java

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u45-b14/jdk-8u45-linux-x64.tar.gz"

tar xvf jdk-8u45-linux-x64.tar.gz -C /opt/java
update-alternatives --install /usr/bin/java java /opt/java/jdk1.8.0_45/bin/java 1
update-alternatives --set java /opt/java/jdk1.8.0_45/bin/java

然后我安装了Solr：

 wget http://apache.belnet.be/lucene/solr/5.2.1/solr-5.2.1.tgz
 tar xvf solr-5.2.1.tgz
 ./solr-5.2.1/bin/install_solr_service.sh solr-5.2.1.tgz

但安装结束时出现以下错误消息：

 solr.service - LSB: Controls Apache Solr as a Service
 Loaded: loaded (/etc/init.d/solr)
 Active: failed (Result: exit-code) since Wed 2015-11-18 02:29:36 TMT; 5s ago

 Service solr installed.

有谁知道发生了什么事吗？

Answer 1

我让我的同事看看这个问题。他发现了两个错误原因：

1) 内存不足（我的盒子有 512 MB RAM 内存）。增加内存解决了这个问题。

2) jdk包错误，即架构选择错误。对于不同的 JDK 包看这里：http://www.oracle.com/technetwork/java/javase/downloads/java-se-6u24-download-338091.html.

希望有一天这会节省其他人的时间和精力。

对于Debian和Solr的开发者，如果能想出在Debian 8下如何安装Solr 5的简单回执就好了。例如https://www.digitalocean.com/community/tutorials/how-to-install-solr-5-2-1-on-ubuntu-14-04.

Answer 2

solr 需要解压才能工作。如果系统上没有 unzip，请安装它。

apt-get install unzip

应该可以解决问题。
