Solr4.8.0源码分析(4)之Eclipse Solr调试环境搭建

由于公司里的Solr调试都是用远程jpda进行的，但是家里只有一台电脑所以不能jpda进行调试，这是因为jpda的端口冲突。所以只能在Eclipse 搭建Solr的环境，折腾了一小时终于完成了。

1. JDPA远程调试

搭建换完成Solr环境后，对${TOMCAT_HOME}/bin/startup.sh 最后一行进行修改，如下所示:

1 set JPDA_ADDRESS=70702 exec "$PRGDIR"/"$EXECUTABLE" jpda  start "$@"

后在eclipse新建debug配置，这样就可以远程调试solr了，要注意服务器端Solr.war包的代码与eclipse的Solr代码一致。

 

二.Eclipse 的Solr环境搭建

2.1 Solr的编译

进入solr的目录，运行ant：

 1 192:solr-4.8.0 rcf$ ant 2 Buildfile: /Users/rcf/workspace/java/solr/solr-4.8.0/build.xml 3  4 -projecthelp: 5         [-] Buildfile: /Users/rcf/workspace/java/solr/solr-4.8.0/build.xml 6  7 Main targets: 8  9  check-svn-working-copy       Checks the status of the SVN working copy10  clean                        Clean Lucene and Solr build dirs11  clean-eclipse                Removes all Eclipse configuration files12  clean-idea                   Removes all IntelliJ IDEA configuration files13  clean-jars                   Remove all JAR files from lib folders in the checkout14  clean-maven-build            Clean up Maven POMs in working copy15  clean-netbeans               Removes all Netbeans configuration files16  compile                      Compile Lucene and Solr17  compile-test                 Compile Lucene and Solr tests and test-frameworks18  documentation                Generate Lucene and Solr Documentation19  documentation-lint           Validates the generated documentation (HTML errors, broken links,...)20  eclipse                      Setup Eclipse configuration21  generate-maven-artifacts     Generate Maven Artifacts for Lucene and Solr22  get-maven-poms               Copy Maven POMs from dev-tools/maven/ to maven-build/23  idea                         Setup IntelliJ IDEA configuration24  ivy-bootstrap                Download and install Ivy in the users ant lib dir25  jar                          Build Lucene and Solr Jar files26  jar-checksums                Recompute SHA1 checksums for all JAR files.27  jar-src                      Build Lucene and Solr Source Jar files28  netbeans                     Setup Netbeans configuration29  nightly-smoke                Builds an unsigned release and smoke tests it30  pitest                       Run PITest on both Lucene and Solr31  precommit                    Run basic checks before committing32  rat-sources                  Runs rat across all sources and tests33  regenerate                   Runs all code regenerators34  remove-maven-artifacts       Removes all Lucene/Solr Maven artifacts from the local repository35  resolve                      Resolves all dependencies36  run-clover                   Runs all tests to measure coverage and generates report (pass "ANT_OPTS=-Xmx1536M" as environment)37  run-maven-build              Runs the Maven build using automatically generated POMs38  test                         Test both Lucene and Solr39  test-help                    Test runner help40  test-with-heapdumps          Runs tests with heap dumps on OOM enabled (if VM supports this)41  validate                     Validate dependencies, licenses, etc.42  validate-maven-dependencies  Validates maven dependencies, licenses, etc.43 Default target: -projecthelp44 45 BUILD SUCCESSFUL46 Total time: 0 seconds

运行 ant eclipse就可以对solr源码进行编译成eclipse工程。在编译ant eclipse时候可能会失败，这是可以运行 ant ivy-bootstrap

2.2 将eclipse工程转换成WEB工程

将编译好的solr工程导入eclipse，后右键点击Properties，选中Project Facets,如图所示

选择OK后，就转换Solr的WEB工程了，这是有些xml文件会出现错误的红叉叉，不用管它。

2.3 solr.war包生成

进入solr/solr目录，运行ant dist,如下图所示

 1 192:~ rcf$ cd /Users/rcf/workspace/java/solr/solr-4.8.0/solr 2 192:solr rcf$ ls 3 CHANGES.txt        README.txt        build.xml        contrib            docs            package            solrj 4 LICENSE.txt        SYSTEM_REQUIREMENTS.txt    cloud-dev        core            example            scripts            test-framework 5 NOTICE.txt        build            common-build.xml    dist            licenses        site            webapp 6 192:solr rcf$ ant dist 7 Buildfile: /Users/rcf/workspace/java/solr/solr-4.8.0/solr/build.xml 8      [echo] Building solr... 9 10 init-dist:11 12 dist-solrj:13      [echo] Building solr-solrj...14 15 check-lucene-core-uptodate:16 17 jar-lucene-core:

编译完成后会再dist目录下生产solr.war包

2.4 solr配置

1. 将solr.war copy到solr/WebContent目录下并进行解压。

2. 在WebRoot/META-INF目下创建context.xml 文件，配置solr/home。

1 <?xml version=‘1.0‘ encoding=‘utf-8‘?>2 <Context> 3          <Environment name="solr/home" type="java.lang.String" value=http://www.mamicode.com/"/Users/rcf/workspace/java/solr/Solr" override="true" />4 </Context>

3. 创建solr/home,在里面放入solr.xml

 1 <?xml version="1.0" encoding="UTF-8" ?> 2 <solr> 3     <solrcloud> 4         <str name="host">${host:}</str> 5         <int name="hostPort">${jetty.port:8983}</int> 6         <str name="hostContext">${hostContext:solr}</str> 7         <int name="zkClientTimeout">${zkClientTimeout:30000}</int> 8         <bool name="genericCoreNodeNames">${genericCoreNodeNames:true}</bool> 9     </solrcloud>10     <shardHandlerFactory name="shardHandlerFactory" class="HttpShardHandlerFactory">11         <int name="socketTimeout">${socketTimeout:0}</int>12         <int name="connTimeout">${connTimeout:0}</int>13     </shardHandlerFactory>14  </solr>

4.这样就可以进行调试solr了。

 

三.Solr环境搭建

真实的solr环境搭建，跟eclipse的环境搭建类似，主要分为以下几步：

1. 对solr源码进行编译，ant dist生成solr.war

2. 下载tomcat并进行安装(tomcat的配置并不需要修改)

3. 将solr.war 复制到 ${TOMCAT_HOME}/wepapps目录下并将solr.war包解压成solr目录

4. 将solr/dist目录下的jar包全部拷贝到${TOMCAT_HOME}/wepapps/solr/lib目录下

5. 在${TOMCAT_HOME}/conf/Catalina/localhost/创建solr.xml,里面设置了solr/home

1 <Context docBase="/Users/rcf/workspace/java/tomcat/apache-tomcat-8.0.9/webapps/solr.war" debug="0" crossContext="true" >2      <Environment name="solr/home" type="java.lang.String" value=http://www.mamicode.com/"/Users/rcf/workspace/java/solr/Solr" override="true" />3 </Context>

6. 创建solr/home，也创建solr.xml

 1 <?xml version="1.0" encoding="UTF-8" ?> 2  <solr> 3      <solrcloud> 4          <str name="host">${host:}</str> 5          <int name="hostPort">${jetty.port:8983}</int> 6          <str name="hostContext">${hostContext:solr}</str> 7          <int name="zkClientTimeout">${zkClientTimeout:30000}</int> 8          <bool name="genericCoreNodeNames">${genericCoreNodeNames:true}</bool> 9      </solrcloud>10      <shardHandlerFactory name="shardHandlerFactory" class="HttpShardHandlerFactory">11          <int name="socketTimeout">${socketTimeout:0}</int>12          <int name="connTimeout">${connTimeout:0}</int>13      </shardHandlerFactory>14   </solr>

7. 在将solr源码包里的log4j.properties 拷贝到${TOMCAT_HOME}/lib目录下，并修改log文件路径

 1   1 #  Logging level 2   2 solr.log=/Users/rcf/workspace/java/tomcat/apache-tomcat-8.0.9/logs 3   3 log4j.rootLogger=INFO, file, CONSOLE 4   4  5   5 log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender 6   6  7   7 log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout 8   8 log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x \u2013 %m%n 9   9 10  10 #- size rotation with log cleanup.11  11 log4j.appender.file=org.apache.log4j.RollingFileAppender12  12 log4j.appender.file.MaxFileSize=4MB13  13 log4j.appender.file.MaxBackupIndex=914  14 15  15 #- File to log to and log format16  16 log4j.appender.file.File=${solr.log}/solr.log17  17 log4j.appender.file.layout=org.apache.log4j.PatternLayout18  18 log4j.appender.file.layout.ConversionPattern=%-5p - %d{yyyy-MM-dd HH:mm:ss.SSS}; %C; %m\n19  19 20  20 log4j.logger.org.apache.zookeeper=WARN21  21 log4j.logger.org.apache.hadoop=WARN22  22 23  23 # set to INFO to enable infostream log messages24  24 log4j.logger.org.apache.solr.update.LoggingInfoStream=OFF
