Quick and dirty how to for SOLR. This is a draft. So please give me feedback. Thanks

The following steps are tested on Gentoo.

Download solr-4.6.0.tgz from official website and save to /usr/local/src (or wherever you prefer)

Install a java JRE, for example:

USE="-X -alsa -cjk -cups -doc -examples -nsplugin -source"
emerge dev-java/icedtea-bin


USE-flags for dovecot that I use:

USE="bzip2 caps imapc ipv6 maildir managesieve mbox mdbox mysql pam pop3c sdbox sieve solr sqlite ssl suid tcpd zlib -cydir -doc -kerberos -ldap -lucene -postgres -selinux -static-libs -vpopmail"


Setting up solr stuff:


cd /opt
tar xvzf /usr/local/src/solr-4.6.0.tgz
cd /opt/solr/example/solr/collection1/conf
mv schema.xml schema.xml-dist
cp /usr/share/doc/dovecot-2.2.9/solr-schema.xml.bz2 schema.xml.bz2
bunzip2 schema.xml.bz2
cd /etc/local.d/


vi solr.start:


# Start Solr
cd /opt/solr-4.6.0/example/
nohup java -jar start.jar &



chmod +x solr.start
./solr.start

cd /etc/dovecot/conf.d


vi 90-plugin.conf:


plugin {
fts = solr
fts_solr = break-imap-search url=http://localhost:8983/solr/
fts_autoindex = yes
}


vi 10-mail.conf:


mail_plugins = ... fts fts_solr ...


Restart dovecot server
/etc/init.d/dovecot restart

crontab -e


# Apache-SOLR
0 0 * * * curl http://localhost:8983/solr/update?optimize=true
*/1 * * * * curl http://localhost:8983/solr/update?commit=true >/dev/null 2>&1


Ready. Enjoy 🙂

That’s what it looks like, if you do a ssh forward like:


ssh -L8983:localhost:8983 your.mailserver.tld


Also a quick look here:


cd /opt/solr-4.6.0/example/solr/collection1/data/:
