CentOS下安装Solr5.5
来源:互联网 发布:vasp windows版 编辑:程序博客网 时间:2024/05/21 09:13
需要Java Runtime Environment(JRE) 1.7或更高版本,先验证。
# java -version
安装可参考《在CentOS下安装JDK8》,包含JRE。
去http://apache.opencas.org/lucene/solr/5.5.0/下载Solr安装文件solr-5.5.0.tgz。
将solr-5.5.0.tgz文件放到/tmp目录下,执行如下脚本:
# cd /tmp
# tar -zxvf solr-5.5.0.tgz // 解压压缩包
创建应用程序和数据目录
# mkdir -p /data/solr /usr/local/solr
创建运行solr的用户并赋权
# groupadd solr
# useradd -g solr solr
# chown -R solr.solr /data/solr /usr/local/solr
安装solr服务
# solr-5.5.0/bin/install_solr_service.sh solr-5.5.0.tgz -d /data/solr -i /usr/local/solr
检查服务状态
# service solr status
将会看到如下输出:
Solr process 3359 running on port 8983
{
"solr_home":"/data/solr/data",
"version":"5.5.0 2a228b3920a07f930f7afb6a42d0d20e184a943c - mike - 2016-02-16 15:22:52",
"startTime":"2016-03-22T02:35:52.306Z",
"uptime":"0 days, 0 hours, 23 minutes, 38 seconds",
"memory":"32.2 MB (%6.6) of 490.7 MB"}
定位到solr应用程序目录
# cd /usr/local/solr/solr
查看solr命令选项
# ./bin/solr
Usage: solr COMMAND OPTIONS where COMMAND is one of: start, stop, restart, status, healthcheck, create, create_core, create_collection, delete
Standalone server example (start Solr running in the background on port 8984):
./solr start -p 8984
SolrCloud example (start Solr running in SolrCloud mode using localhost:2181 to connect to ZooKeeper, with 1g max heap size and remote Java debug options enabled):
./solr start -c -m 1g -z localhost:2181 -a "-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044"
Pass -help after any COMMAND to see command-specific usage information, such as: ./solr start -help or ./solr stop -help
# ./bin/solr start -help
Usage: solr start [-f] [-c] [-h hostname] [-p port] [-d directory] [-z zkHost] [-m memory] [-e example] [-s solr.solr.home] [-a "additional-options"] [-V]
-f Start Solr in foreground; default starts Solr in the background and sends stdout / stderr to solr-PORT-console.log
-c or -cloud Start Solr in SolrCloud mode; if -z not supplied, an embedded ZooKeeper instance is started on Solr port+1000, such as 9983 if Solr is bound to 8983
-h <host> Specify the hostname for this Solr instance
-p <port> Specify the port to start the Solr HTTP listener on; default is 8983 The specified port (SOLR_PORT) will also be used to determine the stop port STOP_PORT=($SOLR_PORT-1000) and JMX RMI listen port RMI_PORT=(1$SOLR_PORT). For instance, if you set -p 8985, then the STOP_PORT=7985 and RMI_PORT=18985
-d <dir> Specify the Solr server directory; defaults to server
-z <zkHost> ZooKeeper connection string; only used when running in SolrCloud mode using -c To launch an embedded ZooKeeper instance, don't pass this parameter.
-m <memory> Sets the min (-Xms) and max (-Xmx) heap size for the JVM, such as: -m 4g results in: -Xms4g -Xmx4g; by default, this script sets the heap size to 512m
-s <dir> Sets the solr.solr.home system property; Solr will create core directories under this directory. This allows you to run multiple Solr instances on the same host while reusing the same server directory set using the -d parameter. If set, the specified directory should contain a solr.xml file, unless solr.xml exists in ZooKeeper. This parameter is ignored when running examples (-e), as the solr.solr.home depends on which example is run. The default value is server/solr.
-e <example> Name of the example to run; available examples: cloud: SolrCloud example techproducts: Comprehensive example illustrating many of Solr's core capabilities dih: Data Import Handler schemaless: Schema-less example
-a Additional parameters to pass to the JVM when starting Solr, such as to setup Java debug options. For example, to enable a Java debugger to attach to the Solr JVM you could pass: -a "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=18983" In most cases, you should wrap the additional parameters in double quotes.
-noprompt Don't prompt for input; accept all defaults when running examples that accept user input
-V Verbose messages from this script
# ./bin/solr create -help
Usage: solr create [-c name] [-d confdir] [-n configName] [-shards #] [-replicationFactor #] [-p port]
Create a core or collection depending on whether Solr is running in standalone (core) or SolrCloud mode (collection). In other words, this action detects which mode Solr is running in, and then takes the appropriate action (either create_core or create_collection). For detailed usage instructions, do:
bin/solr create_core -help
or
bin/solr create_collection –help
运行安装脚本
# /tmp/solr-5.5.0/bin/install_solr_service.sh
ERROR: Must specify the path to the Solr installation archive, such as solr-5.0.0.tgz
Usage: install_solr_service.sh path_to_solr_distribution_archive OPTIONS
The first argument to the script must be a path to a Solr distribution archive, such as solr-5.0.0.tgz (only .tgz or .zip are supported formats for the archive)
Supported OPTIONS include:
-d Directory for live / writable Solr files, such as logs, pid files, and index data; defaults to /var/solr
-i Directory to extract the Solr installation archive; defaults to /opt/ The specified path must exist prior to using this script.
-p Port Solr should bind to; default is 8983
-s Service name; defaults to solr
-u User to own the Solr files and run the Solr process as; defaults to solr This script will create the specified user account if it does not exist.
NOTE: Must be run as the root user
# su - solr -c "/usr/local/solr/solr/bin/solr create -c gettingstarted -n data_driven_schema_configs"
Setup new core instance directory: /data/solr/data/gettingstarted
Creating new core 'gettingstarted' using command: http://localhost:8983/solr/admin/cores?action=CREATE&name=gettingstarted&instanceDir=gettingstarted
