Ubuntu openjdk + Tomcat 7 Installation

This is an installation record. I have browsed many articles on solr installation and configuration before and when I encountered problems. Thanks to all the authors for sharing them. Solr4.3.0 was installed in Ubuntu12.04 + OpenJDK1.7, which is somewhat different from the existing articles on the Internet.

This is an installation record. I have browsed many articles on solr installation and configuration before and when I encountered problems. Thanks to all the authors for sharing them. It was found that Solr 4.3.0 was installed on Ubuntu 12.04 + OpenJDK 1.7, which is somewhat different from the existing articles on the Internet.

Install Ubuntu 12.04-after basic installation, only install openssh

Install Openjdk
Linuxidc @ ubsolr :~ $ Sudo apt-get-y install openjdk-7-jdk

Check the JDK installation path:
Linuxidc @ ubsolr :~ $ Ls/usr/lib/jvm
Java-1.7.0-openjdk-i386 java-7-openjdk-commonjava-7-openjdk-i386

Linuxidc @ ubsolr :~ $ Ls/usr/lib/jvm/java-7-openjdk-i386
Linuxidc @ ubsolr :~ $ Ls/usr/lib/jvm/java-7-openjdk-i386/bin

Add JDK environment variables:
Linuxidc @ ubsolr :~ $ Sudo nano/etc/profile

Export JAVA_HOME =/usr/lib/jvm/java-7-openjdk-i386
Export JRE_HOME =$ {JAVA_HOME}/jre
Export CLASSPATH =. :$ {JAVA_HOME}/lib :$ {JRE_HOME}/lib
Export PATH =$ {JAVA_HOME}/bin :$ {JRE_HOME}/bin: $ PATH

 

Restart the system and check the JAVA Configuration:

Linuxidc @ ubsolr :~ $ Env
Linuxidc @ ubsolr :~ $ Java-version
Linuxidc @ ubsolr :~ $ Echo $ JAVA_HOME

 

 

Install Apache2 and Tomcat7

Linuxidc @ ubsolr :~ $ Sudo apt-get-y install apache2 apache2-prefork-dev libapr1-dev libaprutil1-dev
Linuxidc @ ubsolr :~ $ Sudo apt-get update
Linuxidc @ ubsolr :~ $ Sudo apt-get-y install tomcat7 tomcat7-admin

 

After Tomcat 7 is installed, the related directories and configurations are in the following directories:

/Usr/share/tomcat7
/Var/lib/tomcat7/webapps
/Etc/tomcat7/Catalina/localhost

 

Download sample. war from the http://tomcat.apache.org/tomcat-6.0-doc/appdev/sample/, put sample. war in/var/lib/tomcat7/webapps, and restart Tomcat7:

Linuxidc @ ubsolr :~ $ Sudo/etc/init. d/tomcat7 restart

 

Enter the Host IP address in the browser (My Host IP address is 192.168.56.10)

Http: // 192.168.56.10: 8080/sample

You can see the sample page, so that JDK and tomcat 7 are fully operating normally.

 

 

Install Solr 4.3.0

Linuxidc @ ubsolr :~ $ Sudo/etc/init. d/tomcat7 stop

Linuxidc @ ubsolr :~ $ Sudo tar xzvf solr-4.3.0.tgz

Linuxidc @ ubsolr :~ $ Ls solr-4.3.0/dist.

Solr-4.3.0.war

 

Copy the extracted solr-4.3.0.war to tomcat7/webapps and change it to solr. war.

Linuxidc @ ubsolr :~ $ Sudo cp solr-4.3.0/dist/solr-4.3.0.war/var/lib/tomcat7/webapps/solr. war

 

Create a directory/var/solr as the Solr home directory (solr. solr. home)

Linuxidc @ ubsolr :~ $ Sudo mkdir-p/var/solr

 

Copy the decompressed example/solr to the solr. solr. home directory. This will be an instance of collection1.
Linuxidc @ ubsolr :~ $ Sudo cp-R solr-4.3.0/example/solr/*/var/solr

Linuxidc @ ubsolr :~ $ Ls/var/solr

Linuxidc @ ubsolr :~ $ Sudo chown-R tomcat7/var/solr

We recommend a solr. xml file in/etc/tomcat7/Catalina/localhost to specify the solr path.

Linuxidc @ ubsolr :~ $ Sudo nano/etc/tomcat7/Catalina/localhost/solr. xml

 

In the preceding settings, my solr. war (including the solr directory generated later) is stored in/var/lib/tomcat7/webapps.

While instance collection1 is stored in/var/solr

 

Put the instance collection1 (and core0, core1) path to the system variable (in the file/etc/profile ):

Linuxidc @ ubsolr :~ $ Sudo nano/etc/profile

Export JAVA_OPTIONS = "-Dsolr. solr. home =/var/solr $ JAVA_OPTIONS"

Copy the decompressed solr-related lib to the/lib directory of Tomcat 7:
Linuxidc @ ubsolr :~ $ Ls solr-4.3.0/example/lib/ext

Jcl-over-slf4j-1.6.6.jar log4j-1.2.16.jar slf4j-log4j12-1.6.6.jar
Jul-to-slf4j-1.6.6.jar slf4j-api-1.6.6.jar

Linuxidc @ ubsolr :~ $ Ls/usr/share/tomcat7/lib

Linuxidc @ ubsolr :~ $ Sudo cp-R solr-4.3.0/example/lib/ext/*/usr/share/tomcat7/lib

Linuxidc @ ubsolr :~ $ Sudo cp solr-4.3.0/example/resources/log4j. properties/usr/share/tomcat7/lib
