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

1、zookeeper

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=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/home/hadoop/package/zookeeper-3.4.5/data
# the port at which the clients will connect
clientPort=2181
server.1=192.168.0.146:2888:3888
server.2=192.168.0.142:2888:3888
server.3=192.168.0.145:2888:3888

需要修改的：
dataDir=/home/hadoop/package/zookeeper-3.4.5/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.1=192.168.0.146:2888:3888  里面的值是1 

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"

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