solr 在ubuntu上配置

需要把solr服务器安装到linux环境：
第一步：安装linux、jdk、tomcat。
[root@bogon ~]# ll
total 8044
-rw-r–r–. 1 root root 8234674 Oct 27 2013 apache-tomcat-7.0.47.tar.gz
[root@bogon ~]# tar -zxf apache-tomcat-7.0.47.tar.gz
[root@bogon ~]# ll
total 8048
drwxr-xr-x. 9 root root 4096 Sep 10 17:55 apache-tomcat-7.0.47
-rw-r–r–. 1 root root 8234674 Oct 27 2013 apache-tomcat-7.0.47.tar.gz
[root@bogon ~]# mkdir /usr/local/solr
[root@bogon ~]# cp apache-tomcat-7.0.47 /usr/local/solr/tomcat
cp: omitting directory `apache-tomcat-7.0.47’
[root@bogon ~]# cp apache-tomcat-7.0.47 /usr/local/solr/tomcat -r
[root@bogon ~]# cd /usr/local/solr/
[root@bogon solr]# ll
total 4
drwxr-xr-x. 9 root root 4096 Sep 10 17:56 tomcat
[root@bogon solr]#
第二步：把solr的压缩包上传到服务器。并解压。
第三步：把/root/solr-4.10.3/dist/solr-4.10.3.war包部署到tomcat下。并改名为solr.war
[root@bogon dist]# cp solr-4.10.3.war /usr/local/solr/tomcat/webapps/solr.war
第四步：解压war包。启动tomcat自动解压。关闭tomcat。删除solr.war.
第五步：把/root/solr-4.10.3/example/lib/ext 目录下所有的jar包复制到solr工程中。
[root@bogon ext]# cp * /usr/local/solr/tomcat/webapps/solr/WEB-INF/lib/
第六步：创建solrhome。Solrhome是存放solr服务器所有配置文件的目录。
[root@bogon example]# pwd
/root/solr-4.10.3/example
[root@bogon example]# cp -r solr /usr/local/solr/solrhome
[root@bogon example]#
第七步：告诉solr服务器solrhome的位置。
需要修改solr工程的web.xml文件。

配置好后出现问题

需要分配权限

**sudo chown -R xiamo /var/lib/tomcat7/webapps/**
