Solr setup

    Adding new port

    e.g., for viewing Solrtm - 8983

    yum install policycoreutils-python

    semanage port -l

    semanage port -a -t http_port_t -p tcp 8983

    netstat -tnlp

    netstat -anp | grep  8983

    semanage port -l | grep solr

    nano /usr/lib/firewalld/services/solr-server.xml

    nano /etc/services

    ss -tnlp|grep solr

     Configuring sudo access

    1. Log in to the system as the
      root user.
    2. Create a normal user account using the
      useradd command. Replace USERNAME with the user name that you wish to create.
      useradd <USERNAME>
    3. Set a password for the new user using the
      passwd command.
      passwd <USERNAME>
      Changing password for user USERNAME. New password: Retype new password: passwd: all authentication tokens updated successfully.
    4. Run the
      visudo to edit the /etc/sudoers file. This file defines the policies applied by the
      sudo command.
      visudo
    5. Find the lines in the file that grant
      sudo access to users in the group wheel when enabled.
      ## Allows people in group wheel to run all commands
# %wheel        ALL=(ALL)       ALL
    6. Remove the comment character (#) at the start of the second line. This enables the configuration option.
    7. Save your changes and exit the editor.
    8. Add the user you created to the
      wheel group using the usermod command.
      usermod -aG wheel <USERNAME>
    9. Test that the updated configuration allows the user you created to run commands using sudo.
      1. Use the su to switch to the new user account that you created.
        su USERNAME -
      2. Use the groups to verify that the user is in the wheelgroup.
        $ groups USERNAME wheel
      3. Use the sudocommand to run the whoami command. As this is the first time you have run a command using sudofrom this user account the banner message will be displayed. You will be also be prompted to enter the password for the user account.
        $sudo whoami
        We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things: #1) Respect the privacy of others. #2) Think before you type. #3) With great power comes great responsibility. [sudo] password for USERNAME: root
        The last line of the output is the user name returned by the
        whoami command. If sudo is configured correctly this value will be root
        .

    Started Solr server on port 8983 (pid=15613). Happy searching!

    Check if Solr is Running

    yum install lsof

    If you’re not sure if Solr is running locally, you can use the status command:

    bin/solr status

    This will search for running Solr instances on your computer and then gather basic information about them, such as the version and memory usage.

    service httpd restart

    Start and Restart

    The start command starts Solr. The restart command allows you to restart Solr while it is already running or if it has been stopped already.

    The start and restart commands have several options to allow you to run in SolrCloud mode, use an example configuration set, start with a hostname or port that is not the default and point to a local ZooKeeper ensemble.

    bin/solr start [options]

    bin/solr start -help

    bin/solr restart [options]

    bin/solr restart -help

    Solr Extension

    chown -R apache:apache /root/solr-7.7.0
     
      chmod 755 -R /root/solr-7.7.0

    You need to edit /etc/sysctl.conf file and put following line so that after reboot the setting will remain as it is:
    # vi /etc/sysctl.conf
    Append a config directive as follows:
    fs.file-max = 100000
    Save and close the file. Users need to log out and log back in again to changes take effect or just type the following command:
    # sysctl -p
    Verify your settings with command:
    # cat /proc/sys/fs/file-max
