solr +zookeeper＋tomcat 集群搭建

最近需要搭建一个cloudSolr集群，写下记录。基础环境是在centos6.5 64bit

3个下载地址：

1、下载Solr-4.x http://lucene.apache.org/solr/downloads.html
2、下载Tomcat http://tomcat.apache.org/download-70.cgi
3、下载Zookeeper http://zookeeper.apache.org/releases.html

第一：安装zookeeper集群

zookeeper的安装比较简单

记得关闭防火墙，否则会提示启动失败(重要)

chkconfig iptables off 重启后生效

在zoo.cfg配置文件中

tickTime=

# The number of ticks that the initial

# synchronization phase can take

initLimit=

# The number of ticks that can pass between

# sending a request and getting an acknowledgement

syncLimit=

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

dataDir=/home/hadoop/package/zookeeper-3.4./data

# the port at which the clients will connect

clientPort=

server.=192.168.0.146::

server.=192.168.0.142::

server.=192.168.0.145::

需要修改的：

dataDir=/home/hadoop/package/zookeeper-3.4./data

里需要创建一个myid文件里面的值是配置文件中server.后的值

如：server.=192.168.0.146::  里面的值是1

第二：安装tomcat+solr集成

参照我上篇文章tomcat集成solr

http://www.cnblogs.com/zhanggl/p/3897105.html

在主节点147 安装后，复制到148，149 服务器上。

第三zk和solr+tomcat集成

修改tomcat 下配置文件：在主192.168.0.157 服务器上的tomcat 目录下bin的
配置文件

JAVA_OPTS = "
-DzkHost=192.168.0.157:2181,192.168.0.158:2181,192.168.0.159:2181
-Dbootstrap_confdir=/home/hadoop/package/solrhome/collection1/conf -Dcollection.configName=myconf
-Dbootstrap_conf=true
-DnumShards=2"

在192.168.0.158， 192.168.0.159 服务上的tomcat bin目录下catalina.sh 添加

set JAVA_OPTS = -DzkHost=192.168.0.157:2181,192.168.0.158:2181,192.168.0.159:2181

打开后出现错误提示：

Loading of "/solr/zookeeper?wt=json" failed (HTTP-Status )

"Zookeeper is not configured for this Solr Core. Please try connecting to an alternate zookeeper address."

将配置文件复制到其他服务器上：

java -classpath .:/home/hadoop/cloudsolr/tomcat-7.0.55/webapps/solr/WEB-INF/lib/* org.apache.solr.cloud.ZkCLI -cmd upconfig -zkhost 192.168.0.157:2181,1192.168.0.158:2181,192.168.0.159:2181 -confdir /home/hadoop/cloudsolr/solrhome/collection1/conf -confname myconf

同步到节点：

java -classpath .:/home/hadoop/cloudsolr/tomcat-7.0.55/webapps/solr/WEB-INF/lib/* org.apache.solr.cloud.ZkCLI -cmd linkconfig -collection collection1 -confname myconf -zkhost 192.168.0.157:2181,1192.168.0.158:2181,192.168.0.159:2181

错误提示：log4j:WARN No appenders could be found for logger (org.apache.zookeeper.ZooKeeper).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

错误提示

adoop@slave3 solrlib]$ java -classpath .:/home/hadoop/package/solrlib/*  org.apache.solr.cloud.ZkCLI -cmd upconfig -zkhost 192.168.0.157:2181,192.168.0.158:2181,192.168.0.159:2181 -confdir .:/home/hadoop/package/solrconfig -confname myconf

解决办法：下载http://yunpan.cn/cdpSQiMZbfe33 （提取码：49e0）将jar导入即可

1、启动的时候错误提示：

Load collection config from:/collections/collection1

org.apache.solr.common.cloud.ZooKeeperException: Specified config does not exist in ZooKeeper:collection1

错误原因：

启动错误提示：
