Installing Java

Step 1.) Execute the Java JDK installation with the command:

shell> rpm –ivh  jdk-8u101-linux-x64.rpm

Step 2.) Set the /usr/bin/java (also: javac javaws javadoc jar jcontrol) symbolic links to point to where the rpm installed the JDK.

shell> cd /usr/bin 
shell> rm -f java
shell> ln -s /usr/java/default/bin/java java

Step 3.) Add the JAVA_HOME environment variable to point to the location where Sun/Oracle Java version 8 Update 101 was installed.

shell> export JAVA_HOME=/usr/java/default

Step 4.) Update the PATH variable to point to the bin folder.

shell> export PATH=/usr/java/default/bin:$PATH

 
Step 5.) Optional: Verify the java installation version - Sun/Oracle Java JDK 8

shell> java –version

Installing MySQL

Step 1.) Install MySQL RPMs in the order shown below:

shell> rpm -ivh MySQL-client-5.6.33-1.linux_glibc2.5.x86_64.rpm
shell> rpm -ivh MySQL-shared-5.6.33-1.linux_glibc2.5.x86_64.rpm
shell> rpm -ivh MySQL-devel-5.6.33-1.linux_glibc2.5.x86_64.rpm
shell> rpm -ivh MySQL-server-5.6.33-1.linux_glibc2.5.x86_64.rpm

Step 2.) Set the MySQL root user password.  “server” rpm installation typically displays the following message. 

• A random password has been set for the MySQL root user.
  • You can find the password in "/root/.mysql_secret".
  • When you first connect to the server, change the password.

Step 2.1) Start the MySQL server.

shell> /etc/init.d/mysql start

Step 2.2.) Get the auto-generated password.

shell> cat /root/.mysql_secret

Step 3.) Connect to MySQL using the auto-generated password from the .mysql_secret file and change the root password using the following commands:

shell> mysql -uroot -p
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('<ANYTHING YOU WANT>');
mysql> SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('<ANYTHING YOU WANT>');
mysql> flush privileges;
mysql> quit

Step 4.) Create or modify the my.cnf file as shown below.

• Typically the my.cnf file is in /etc/ folder

shell> vi /etc/my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
max_allowed_packet = 150M
max_connections = 600
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_unicode_ci
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_unicode_ci

[mysql]
max_allowed_packet = 150M

[mysqldump]
quick
max_allowed_packet = 150M

Step 5.) Restart MySQL.

• Based on the standard MySQL installation, a MySQL script is added to the init.d directory that you can use to Start and Stop the MySQL server.

shell> /etc/init.d/mysql start
shell> /etc/init.d/mysql stop

Install Elastic Search

Step 1.) Download the .rpm file using either methods below:

• Download using the linux shell command prompt
  • Run the following command:
    • sudo rpm -ivh elasticsearch-5.5.0.rpm
• Download using the wget command from the linux shell command prompt
  • You can download the rpm file here.
    
    

Step 2.) Navigate to the installation path (Eetc/elasticsearch) >> elasticsearch.yml file

Step 3.) Edit the elasticsearch.yml file

• Change and update the following parameters:

cluster.name: zephyr
node.name: "Node1"
node.master: true
node.data: true

script.disable_dynamic: false
script.inline: true
script.indexed: true

index.number_of_shards: 2
index.number_of_replicas: 1

network.bind_host: 192.168.45.21
network.publish_host: 192.168.45.21
network.host: 192.168.45.21
transport.tcp.port: 9300
http.port: 9200

discovery.zen.ping.timeout: 3s
discovery.zen.ping.unicast.hosts: ["192.168.45.21"]

Step 4.) Save the file.

Step 5.) Start the service by utilizing the following command:

• sudo systemctl start elasticsearch.service

Configure Elastic Search

Step 1.) In JDBC, change the transport nodes in the properties to the following:

#transport|node
transport.nodes=192.168.45.21:9300, 192.168.45.22:9300
