zabbix相关记录zabbix的一些步骤

admin

Make sure that the files have the zabbix user/group and are executable.

# chown zabbix:zabbix /usr/lib/zabbix/externalscripts/*# chmod +x /usr/lib/zabbix/externalscripts/*.sh

The Zabbix user cannot login to the bash by default. We need to enable it as follows (if not already done in RZA6).

usermod --shell /bin/bash zabbix

If not already created, create the HOME directory for the Zabbix user.

usermod -m -d /var/lib/zabbix zabbixchown zabbix:zabbix /var/lib/zabbixchmod 755 /var/lib/zabbix

Create the directories for the saved configuration and firmware files and change the access rights.

mkdir /var/lib/zabbix/configuration-backupmkdir /var/lib/zabbix/configuration-backup/raymkdir /var/lib/zabbix/firmwaremkdir /var/lib/zabbix/firmware/ray3chown -R zabbix:zabbix /var/lib/zabbix/

The directory for the SSH key should now be located in /var/lib/zabbix/.ssh directory. Change the current directory to this one and login as zabbix.

su zabbix

A new prompt appears. We need to upload the SSH keys into every unit we want to control. You can either have you own RSA/DSA key or you can create a new one following this example. Run

ssh-keygen -t rsa

Follow the guide of the ssh-keygen application and leave the passphrase empty. To copy our RSA key into RAy3 units, copy the public part of the key and run the following command:

ssh admin@192.168.132.200

Just replace 192.168.132.200 with the correct RAy3 IP address. The prompt will ask for the admin password, fill it in and click Enter. Now, you should be logged in RAy3 CLI. Run the following command:

vi .ssh/authorized_keys

" N/ n6 ~% k# Z+ v) _5 L

Insert (paste) your public part of the key to a new line. Save the changes and close the file. Logout and check, if you can access the unit without a password.

ssh -i rsa admin@192.168.132.200

We completed all Linux tasks, but we still need to edit Zabbix web interface.

Scripts must be manually created in the Zabbix Administration – Scripts menu. See the example below and create Zabbix scripts for RAy3 units.

If you open one of them, you can modify them as required. If you do not have any, you need to create them from scratch.

Configuration backup – the script creates a configuration backup file in /var/lib/zabbix/configuration-backup/ray/ directory. The name is taken from RAy3 S/N and Ethernet IP.

• Name: RAy3 Configuration backup
• Scope: Manual host action
• Menu path: RAy3
• Type: Script
• Execute on: Zabbix server
• Commands:
  /usr/lib/zabbix/externalscripts/ray_cli_cnf_backup_get.sh {HOST.CONN} {$HOST_SSHKEY} {$HOST_SSHPORT} 2>>/usr/lib/zabbix/externalscripts/script-log.txt

Set other parameters to suit your needs.

Displaying firmware version – the script reads a current FW version installed in RAy3 unit.

All is the same, except the “Commands” parameter:

/usr/lib/zabbix/externalscripts/ray_cli_fw_show.sh {HOST.CONN} {$HOST_SSHKEY} {$HOST_SSHPORT} 2>>/usr/lib/zabbix/externalscripts/script-log.txt

Upgrading firmware version – the script uploads a firmware file and a special CLI script into local RAy3 unit which is then executed and FW of both units within the link are upgraded. The script command is:

/usr/lib/zabbix/externalscripts/ray_cli_fw_upgrade.sh {HOST.CONN} {$HOST_SSHKEY} {$HOST_SSHPORT} “/var/lib/zabbix/firmware/ray3/ray3-fw-2.0.3.0.cpio” “2.0.3.0” 2>>/usr/lib/zabbix/externalscripts/script-log.txt

The parameters are MACROs which should be enabled by default due to our Template. Each RAy3 unit uses the SSH port 22 and the SSH key saved in /var/lib/zabbix/.ssh/rsa file by default. If you need to modify any of these parameters, go to the Configuration – Hosts menu and edit the particular Host’s MACROs.

Another script is the Configuration backup. The expected output should display a full path to the stored file.

The last script should be first tested and verified in RAy3 units/links which are e.g., on your desk so that you double-check a correct behaviour.

Zabbix 6.0 LTS offers you to use your own company’s branding instead of Zabbix ones, or RACOM logos in case of using RZA6.

General and brief procedure is described here:

For the RZA6, we created a file /usr/share/zabbix/local/conf/brand.conf.php with this content:

<?phpreturn ['BRAND_LOGO' => 'racom/racom_logo.png','BRAND_LOGO_SIDEBAR' => 'racom/racom_logo.png','BRAND_LOGO_SIDEBAR_COMPACT' => 'racom/racom_logo_compact.png',#'BRAND_HELP_URL' => 'https://www.racom.eu/ APP NOTE LINK '];

Logos were scaled to 140×20 and 20×13 (compact one). The logos are placed in /usr/share/zabbix/racom/ directory. After these changes, the Login screen can look like:

If you need any additional help or information, do not hesitate to contact support@racom.eu. We are ready and happy to help you.

We do recommend using our RZA6 solution. If not in your real network, then as a start for getting familiar with RAy3 SNMP and Zabbix NMS, because RZA6 has many configuration steps pre-configured and done.
