Install

In order to index records and files you will need to complete these steps 

 

 Install standalone Elastic search server 

 Install and configure Tempus Serva file indexing 

 Configure the Tempus Serva installation 

 

 Finally you may want to install optional components to handle OCR (scanned PDF's and images) 

 Install Elastic search 

 Java 8 / Elastic search 6 

 This is the recommended version but requires Java 8. 

 Follow these steps: 

 sudo rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch

 sudo sh -c 'curl https://gist.githubusercontent.com/nl5887/b4a56bfd84501c2b2afb/raw/elasticsearch.repo >> /etc/yum.repos.d/elasticsearch.repo'

 sudo yum update -y

 sudo yum install -y elasticsearch

 sudo chkconfig elasticsearch on 

 The service runner configurations should have updated RAM allowance by adding an extra line in the file 

 sudo nano /etc/sysctl.conf

 vm.max_map_count=262144 

 Restart service and validate settings were updated 

 sudo sysctl --system

 sysctl vm.max_map_count 

 Run the daemon 

 sudo service elasticsearch start 

 Java 7 / Elastic search 1.7 

 This version is an alternate version. 

 Install and unpack files 

 sudo wget https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.6.tar.gz

 tar -xvf elasticsearch-1.7.6.tar.gz

 sudo rm elasticsearch-1.7.6.tar.gz 

 Run as a daemon 

 elasticsearch-1.7.6/bin/elasticsearch -d 

 Test that the service is running 

 curl 'http://localhost:9200/?pretty' 

 Handling crashes 

 ElasticSearch normally requires 1GB of memory, which is in the default memory configuation 

 sudo nano /etc/elasticsearch/jvm.options 

 Set the maximum memory entry to a lower value 

 -Xmx256m 

 Then restart the service 

 sudo service elasticsearch restart 

 Fixing: "curl: (7) Failed to connect to localhost port 9200: Connection refused" 

 In some cases the firewall needs to be configured 

 sudo iptables -I INPUT -p tcp --dport 9200 --syn -j ACCEPT

 sudo iptables -I INPUT -p udp --dport 9200 -j ACCEPT

 sudo iptables-save 

 Install using yum installer 

 sudo rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch

 sudo sh -c 'curl https://gist.githubusercontent.com/nl5887/b4a56bfd84501c2b2afb/raw/elasticsearch.repo >> /etc/yum.repos.d/elasticsearch.repo'

 sudo yum install -y elasticsearch
