Linux+Solr+Zookeeper-01: Build Solr Service (non-cluster) and register it as Service Service Service.

[Super Connection: Linux+Solr+Zookeeper Series - Chapter 1]

This article mainly explains how to build Solr service on Linux server and make it a Service service.

The Solr service built in this paper is non-clustered (non-SolrCloud mode), and is only used for Solr's single service use.

1. environment

Ubuntu 16.04 LTS
jdk1.8.0_161
solr-6.6.0

2. Install JDK and configure environment variables

Install JDK:

//Decompression package
tar -zxvf jdk-8u161-linux-x64.tar.gz 
//Copy the jdk directory to / user/local / directory
sudo cp -r jdk1.8.0_161 /usr/local/

Modify environment variables:

//Install vim command
sudo apt install vim
//Editing System Configuration
sudo vim /etc/profile

Add the following configuration at the end of / etc/profile:

JAVA_HOME=/usr/local/jdk1.8.0_161
JRE_HOME=/usr/local/jdk1.8.0_161/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME JRE_HOME CLASS_PATH PATH

Make configuration effective:

//View the current configuration
hanchao@hanchao-virtual-machine:/etc$ echo $PATH
/home/hanchao/bin:/home/hanchao/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
//Take effect
hanchao@hanchao-virtual-machine:/etc$ source /etc/profile
//Look at the current configuration again
hanchao@hanchao-virtual-machine:/etc$ echo $PATH
/home/hanchao/bin:/home/hanchao/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/usr/local/jdk1.8.0_161/bin:/usr/local/jdk1.8.0_161/jre/bin

View the JDK version

hanchao@hanchao-virtual-machine:/etc$ java -version
java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

3. Download, install and start Solr

Old version of solr download address:

Download solr-6.6.0.tgz

Install Solr:

//decompression
tar -zxvf solr-6.6.0.tgz
//Store the decompressed directory in the specified directory
mv /home/hanchao/solr-6.6.0/ /usr/local/

Start up service:

hanchao@hanchao-virtual-machine:~$ /usr/local/solr-6.6.0/bin/solr start
Waiting up to 180 seconds to see Solr running on port 8983 [\]
Started Solr server on port 8983 (pid=2404). Happy searching!

Test services:

Enter in the browser: http://localhost:8983/solr/ If you can successfully enter the Solr Admin background, the service starts successfully.

Shut down service:

hanchao@hanchao-virtual-machine:~$ /usr/local/solr-6.6.0/bin/solr stop

4.Solr is registered as Service Service Service

Copy installation packages to bin directory:

//Copy solr-6.6.0.tgzto solr/bin Directory
hanchao@hanchao-virtual-machine:~/download $ cp solr-6.6.0.tgz /usr/local/solr-6.6.0/bin/
hanchao@hanchao-virtual-machine:~/download $ cd /usr/local/solr-6.6.0/bin/
hanchao@hanchao-virtual-machine:/usr/local/solr-6.6.0/bin$ ls
init.d  install_solr_service.sh  oom_solr.sh  post  solr  solr-6.6.0.tgz  solr.cmd  solr.in.cmd  solr.in.sh

Registration services:

//Register the service through the install_solr_service.sh script
hanchao@hanchao-virtual-machine:/usr/local/solr-6.6.0/bin$ ./install_solr_service.sh solr-6.6.0.tgz 
ERROR: This script must be run as root

//This script can only be executed under the root user, switching users
hanchao@hanchao-virtual-machine:/usr/local/solr-6.6.0/bin$ su
//Password: 

//Register the service again through the install_solr_service.sh script
root@hanchao-virtual-machine:/usr/local/solr-6.6.0/bin# ./install_solr_service.sh solr-6.6.0.tgz 

id: "solr": no such user
Creating new user: solr
//Adding System Users"solr" (UID 121)...
//Adding a new group"solr" (GID 129)...
//New users are on the way"solr" (UID 121)Add to group"solr"...

Extracting solr-6.6.0.tgz to /opt

Installing symlink /opt/solr -> /opt/solr-6.6.0 ...

Installing /etc/init.d/solr script ...

Installing /etc/default/solr.in.sh ...

Service solr installed.
