Linux部署Apache Solr5.5.2+Apache Zookeeper3.4.6

一、官网下载所需包。

solr-5.5.2.tgz

下载地址：https://mirrors.tuna.tsinghua.edu.cn/apache/lucene/solr/5.5.2/

zookeeper-3.4.6.tar.gz

下载地址：http://apache.org/dist/zookeeper/zookeeper-3.4.6/

solr-5.5.2版本本身已经集成了jetty,所以这里就不需要tomcat了。

二、准备环境

《192.168.0.36服务器》

1.安装JDK 1.7版本以上（You will need the Java Runtime Environment (JRE) version 1.7 or higher.）

略过~~

2.安装zookeeper

创建/usr/solr/文件夹并上传zookeeper-3.4.6.tar.gz到该目录下。

命令进入目录：

cd /usr/solr/

解压文件：

tar -xzvf zookeeper-3.4.6.tar.gz

将解压后得到的zookeeper-3.4.6

创建zookeeper-3.4.6的dataDir文件夹/usr/solr/zookeeper-data。

mkdir zookeeper-data

进入到zookeeper-data目录下创建myid文件。

vi myid

输入1并保存。

进入/usr/solr/zookeeper-3.4.6/conf目录下，拷贝一份zoo_sample.cfg为zoo.cfg

cp zoo_sample.cfg zoo.cfg

修改zoo.cfg中的dataDir=/usr/solr/zookeeper-data

在最后添加：

server.1=192.168.0.36:2999:3999
server.2=192.168.0.33:2999:3999
server.3=192.168.0.32:2999:3999

（端口自己定义）

zoo.cfg文件格式如下：

# The number of milliseconds of each tick
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=/usr/solr/zookeeper-data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=192.168.0.36:2999:3999
server.2=192.168.0.33:2999:3999
server.3=192.168.0.32:2999:3999

3.《192.168.0.32服务器》和《192.168.0.33服务器》

按1-2步骤安装好zookeeper。

修改myid内容

备注：每一台服务器zookeeper-data目录下myid中的内容必须与zoo.cfg中添加的server.后面数字编号一致，代表的是第几台服务器。
