solr cloud的分布式部署演示

今天试了一下solr4的solrcloud部署，发现还是很方便的，借助zookeeper很容易实现高可用分布式部署，由于只是尝试，是在单机上部署，使用不同的端口实现，原理与多机器部署完全一样，本处采用独立的zookeeper集群部署，而没有使用solr集成的zookeeper，集成只能用开发环境

部署zookeeper

创建三个zookeeper实例：

cp -r zookeeper-3.4.6 zookeeper1
cp -r zookeeper-3.4.6 zookeeper2
cp -r zookeeper-3.4.6 zookeeper3

配置文件分别如下：

ookeeper1/conf/zoo.cfg

# 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=/tmp/zookeeper1
# the port at which the clients will connect
clientPort=9983
# 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=localhost:2888:3888
server.2=localhost:4888:5888
server.3=localhost:6888:7888

 

ookeeper2/conf/zoo.cfg

# 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=/tmp/zookeeper2
# the port at which the clients will connect
clientPort=9984
# 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=localhost:2888:3888
server.2=localhost:4888:5888
server.3=localhost:6888:7888

 

ookeeper3/conf/zoo.cfg

# 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=/tmp/zookeeper3
# the port at which the clients will connect
clientPort=9985
# 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=localhost:2888:3888
server.2=localhost:4888:5888
server.3=localhost:6888:7888 

在对应的datadir目录: /tmp/zookeeper1,/tmp/zookeeper2,/tmp/zookeeper3中创建myid文件，分别输入1,2,3。然后分别启动

zookeeper1/bin/zkServer.sh start

zookeeper2/bin/zkServer.sh start

zookeeper3/bin/zkServer.sh start

部署solr

创建两个分片，启动4个solr实例

cp -r example/ solr1

cp -r example/ solr2

cp -r example/ solr3

cp -r example/ solr4

启动第一个solr实例 solr1，这个启动参数与后面稍有不同，需要注意：

cd solr1

java -DzkHost=localhost:9983,localhost:9984,localhost:9985 -DnumShards=2 -Dbootstrap_confdir=./solr/collection/conf -Dcollection.configName=myconf -jar start.jar

其余的实例启动相同：

cd solr2

java -DzkHost=localhost:9984,localhost:9983,localhost:9985 -Djetty.port=8984 -jar start.jar

 

cd solr3

java -DzkHost=localhost:9984,localhost:9983,localhost:9985 -Djetty.port=8985 -jar start.jar

cd solr4

java -DzkHost=localhost:9984,localhost:9983,localhost:9985 -Djetty.port=8986 -jar start.jar
