To install Solr 5.+ on centos 7, you need a JDK, preferably 64 bit:<\/p>\n

\nyum search openjdk\n\nyum -y install java-1.8.0-openjdk.x86_64\n<\/pre>\n
Then, download from a mirror and extract Solr:<\/p>\n
\nwget http:\/\/mirrors.gigenet.com\/apache\/lucene\/solr\/5.2.1\/solr-5.2.1.tgz\n\ntar xvf solr-5.2.1.tgz\n<\/pre>\n
If everything worked, it should be simple to start:<\/p>\n
\ncd solr-5.2.1\n\nbin\/solr start -h 45.55.156.155 -p 8000\n<\/pre>\n
To test that Solr is working, you can use wget. This won\u2019t work until it starts up, which takes a 10-30 seconds:<\/p>\n
\nwget localhost:8000\n<\/pre>\n
Output:<\/p>\n

If this fails after waiting, run solr again with \u201c-f\u201d to see the error.<\/p>\n
\nbin\/solr start -p 8000 -h 45.55.156.155 -p 8000\n<\/pre>\n
If you run out of memory, add the \u201c-m\u201d argument (e.g. -m 256m) – by default Solr uses 512mb.<\/p>\n
\nbin\/solr start -h 45.55.156.155 -p 8000 -f -m 256m\n<\/pre>\n
To access Solr\u2019s administration pages, run SSH and enable port forwarding. With Putty this means adding \u201c-L 8000:localhost:8000\u201d (for our example) to the command line arguments. Once you connect this way, you can use \u201chttp:\/\/localhost:8000\/solr\/#\/\u201d to connect to the Solr admin panel.<\/p>\n","protected":false},"excerpt":{"rendered":"
