Solrcloud单机伪集群部署

线上有一套双节点的Solrcloud节点，因机器性能较老，环境搭建于2013年，原节点有数百个已经被unload的collections，考虑以后可能还会需要，所以搭建一套和原节点相同的solrcloud环境，因为目前只有一台新机器，所以在一台机器上搭建Solrcloud伪双节点集群，

1. 系统参数修改

1.1 内核参数

$ tail -n  /etc/sysctl.conf
vm.overcommit_memory=
vm.overcommit_ratio=
fs.aio-max-nr=
fs.file-max=
net.ipv4.ip_local_port_range=
net.core.rmem_default=
net.core.rmem_max=
net.core.wmem_default=
net.core.wmem_max=
kernel.sem=
kernel.shmall=
kernel.shmmax=

1.2. 资源使用

$ tail -n  /etc/security/limits.conf
tnuser soft nproc
tnuser hard nproc
tnuser soft nofile
tnuser hard nofile 

1.3. 环境变量

$ cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

JAVA_HOME=/usr/java/jdk1..0_12
ZOOKEEPER_HOME=/usr/local/contentplatform/zookeeper-3.4.
JRE_HOME=$JAVA_HOME/jre
CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JRE_HOME/lib
PATH=$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin:$PATH:$HOME/.local/bin:$HOME/bin
export PATH

2. Zookeeper安装

$ mkdir /usr/local/contentplatform
$ cd /usr/local/contentplatform
$ wget http://archive.apache.org/dist/zookeeper/zookeeper-3.4.5/zookeeper-3.4.5.tar.gz
$ tar -zxf zookeeper-3.4..tar.gz
$ mkdir zookeeper-3.4./data
$ cat zookeeper-3.4./conf/zoo.cfg
tickTime=
initLimit=
syncLimit=
dataDir=/usr/local/contentplatform/zookeeper-3.4./data
clientPort=
$ zookeeper-3.4./bin/zkServer.sh start

$ zookeeper-3.4./bin/zkServer.sh status
JMX enabled by default
Using config: /usr/local/contentplatform/zookeeper-3.4./bin/../conf/zoo.cfg
Mode: standalone

3. solr安装

$ cd /usr/local/contentplatform
$ wget https://archive.apache.org/dist/lucene/solr/4.2.1/solr-4.2.1.tgz
$ tar -zxf solr-4.2..tgz
$ mkdir {solr8983,solr8984}
$ cp -r solr-4.2./example/* solr8983/
$ cat solr8983/solr/solr.xml

<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true">
  <cores defaultCoreName="tnpoi" adminPath="/admin/cores" zkClientTimeout="${zkClientTimeout:60000}" hostPort="8983" hostContext="solr">
    <core loadOnStartup="true" shard="shard1" instanceDir="tifbase/" transient="false" name="tnpoi"/>
  </cores>
</solr>

默认的collection为collection1，我将这里改成我实际的collection名tnpoi，注意hostPort的值一定要改成和第一个tomcat的端口号对应

$ cp -r solr8983/* solr8984/
$ cat solr8984/solr/solr.xml

<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true">
  <cores defaultCoreName="tnpoi" adminPath="/admin/cores" zkClientTimeout="${zkClientTimeout:60000}" hostPort="8984" hostContext="solr">
    <core loadOnStartup="true" shard="shard2" instanceDir="tifbase/" transient="false" name="tnpoi"/>
  </cores>
</solr>

注意第二个solr的hostPort的值一定要改成和第二个tomcat的端口号对应

4. tomcat安装

$ cd /usr/local
$ https://archive.apache.org/dist/tomcat/tomcat-6/v6.0.20/bin/apache-tomcat-6.0.20.tar.gz
$ tar -zxf apache-tomcat-6.0..tar.gz
$ mkdir {apache-tomcat-6.0.-,apache-tomcat-6.0.-}
$ rm -rf apache-tomcat-6.0.-/webapps/*
$ unzip contentplatform/solr-4.2.1/example/webapps/solr.war -d apache-tomcat-6.0.20-8983/webapps/solr
$ cp -r /usr/local/contentplatform/solr-4.2.1/dist/*.jar /usr/local/apache-tomcat-6.0.20-8983/webapps/solr/WEB-INF/lib/
$ cp -r /usr/local/contentplatform/solr-4.2.1/contrib/velocity/lib/*.jar /usr/local/apache-tomcat-6.0.20-8983/webapps/solr/WEB-INF/lib/
$ cp -r /usr/local/contentplatform/solr-4.2.1/contrib/extraction/lib/*.jar /usr/local/apache-tomcat-6.0.20-8983/webapps/solr/WEB-INF/lib/
$ cp -r /usr/local/contentplatform/solr-4.2.1/example/lib/*.jar /usr/local/apache-tomcat-6.0.20-8983/webapps/solr/WEB-INF/lib/

修改bin/catalina.sh文件

sh /usr/local/apache-tomcat-6.0.-/bin/createSymbolicConf.sh
JAVA_HOME=/usr/java/jdk1..0_12/
JAVA_OPTS="$JAVA_OPTS -Xms8000M -Xmx8000M -Duser.language=en -Duser.country=US -Dsolr.solr.home=/usr/local/contentplatform/solr8983/solr -DhostContext=solr -Dbootstrap_conf=true -Dhostport=8983 -DzkHost=ec2d-newcntprocdb-01:9983 -DnumShards=2"
echo "Java Options: $JAVA_OPTS"

createSymbolicConf.sh脚本为每次启动tomcat时添加成conf目录软连接到指定的collection下

$ cat apache-tomcat-6.0.-/bin/createSymbolicConf.sh
#!/bin/sh

baseDir=/usr/local/contentplatform/solr8983/solr
confDir=/usr/local/contentplatform/solr8983/solr/tifbase/conf
for subDir in $baseDir/*
do
if [ !  -d $subDir/conf ] && [[ "$subDir" == *poi* ]]
  then
    echo "$subDir don't have conf dir, creating symbolic link"
    ln -sb $confDir $subDir/conf
  fi

done

修改conf/server.xml文件

<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN">

  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

  <Listener className="org.apache.catalina.core.JasperListener" />

              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">

    <Connector port="8983" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

    <Engine name="Catalina" defaultHost="localhost">

      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

      </Host>
    </Engine>
  </Service>

</Server>

修改tomcat下的solr的web.xml文件

    <env-entry>
       <env-entry-name>solr/home</env-entry-name>
       <env-entry-value>/usr/local/contentplatform/solr8983/solr</env-entry-value>
       <env-entry-type>java.lang.String</env-entry-type>
    </env-entry>

将tomcat目录复制一份为第二个tomcat目录

$ cp -r apache-tomcat-6.0.-/* apache-tomcat-6.0.20-8984/

修改第二个tomcat下的bin/catalina.sh文件

sh /usr/local/apache-tomcat-6.0.-/bin/createSymbolicConf.sh
JAVA_HOME=/usr/java/jdk1..0_12/
JAVA_OPTS="$JAVA_OPTS -Xms8000M -Xmx8000M -Duser.language=en -Duser.country=US -Dsolr.solr.home=/usr/local/contentplatform/solr8984/solr -DhostContext=solr -Dbootstrap_conf=true -Dhostport=8984 -DzkHost=ec2d-newcntprocdb-01:9983 -DnumShards=2"
echo "Java Options: $JAVA_OPTS"

修改第二个tomcat的conf/server.xml文件

              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">

    <Connector port="8984" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />

    <Engine name="Catalina" defaultHost="localhost">

      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
             resourceName="UserDatabase"/>

      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">

      </Host>
    </Engine>
  </Service>

</Server>

修改第二个tomcat下的solr的web.xml文件

    </env-entry>

依次启动第一个和第二个tomcat

$ /usr/local/apache-tomcat-6.0.-/bin/catalina.sh start
$ /usr/local/apache-tomcat-6.0.-/bin/catalina.sh start
