Upgrade from the same major version

Upgrade the Wazuh manager

Before upgrading the Wazuh manager, stop ossec-authd to ensure that it is not running in the background. Since Wazuh 2.1.0, ossec-authd should be configured in the auth section of ossec.conf.

1. Upgrade the Wazuh server on CentOS/RHEL/Fedora:

# yum upgrade wazuh-manager

2. Upgrade the Wazuh server on Debian/Ubuntu:

# apt-get update && sudo apt-get install --only-upgrade wazuh-manager

Upgrade the Wazuh API

1. Upgrade the Wazuh API on CentOS/RHEL/Fedora:

# yum upgrade wazuh-api

2. Upgrade the Wazuh API on Debian/Ubuntu:

# apt-get update && sudo apt-get install --only-upgrade wazuh-api

Upgrade the Wazuh agent

1. Upgrade the Wazuh agent on CentOS/RHEL/Fedora:

# yum upgrade wazuh-agent

2. Upgrade the Wazuh agent on Debian/Ubuntu:

# apt-get update && sudo apt-get install --only-upgrade wazuh-agent

Upgrade the Wazuh Kibana App

1. On your terminal, remove the current Wazuh Kibana App:

   # /usr/share/kibana/bin/kibana-plugin remove wazuh
   

2. Once the process is complete, stop Kibana:

1. For Systemd:

# systemctl stop kibana

2. For SysV Init:

# service kibana stop

3. Remove the current Kibana bundles:

# rm -rf /usr/share/kibana/optimize/bundles

4. Upgrade the Wazuh Kibana App (this can take a while):

   1. Increase the default Node.js heap memory limit to prevent out of memory errors when installing the Wazuh App.

   Set the limit as follow:

   # export NODE_OPTIONS="--max-old-space-size=3072"
   

   2. Install the Wazuh App:

   # /usr/share/kibana/bin/kibana-plugin install https://packages.wazuh.com/wazuhapp/wazuhapp.zip
   

5. Once the process is complete, restart Kibana:

1. For Systemd:

# systemctl start kibana

2. For SysV Init:

# service kibana start
