Zabbix on CentOS 5 from RPMs

I've recently been asked to investigate Zabbix and found this guide to installing Zabbix 1.4 on CentOS.

However, I also found that Zabbix RPMs are available in the EPEL repository, which makes installation much mores straight-forward.

Here's what I did…

This guide installs the zabbix server, agent, and web interface on one machine.

The server used was a minimal install of CentOS 5.2.

  1. Make sure the EPEL repository has been added to your system. Details of how to use it are here.
  2. Install zabbix, zabbix-web, zabbix-agent, MySQL server, and net-snmp

yum install zabbix zabbix-web zabbix-agent mysql-server net-snmp

The zabbix packages, and all necessary dependencies are installed:

Note 1: I also have the RPMForge repo enabled on this system. This is not necessary.

Note 2: I am using local mirrors of the repositories from a cobbler server, so the Repository names you see will be slightly different.

  1. Start the mysql server, and configure it to start at boot:

service mysqld start
chkconfig mysqld on

  1. Create a database for zabbix to use:

mysqladmin create zabbix
cat | mysql << EOF
grant all privileges on zabbix.* to 'zabbix'@'localhost' identified by 'password';
EOF

  1. Initialise the zabbix database:

mysql -uzabbix -ppassword zabbix < /usr/share/doc/zabbix-1.4.5/dbinit/schema/mysql.sql
mysql -uzabbix -ppassword zabbix < /usr/share/doc/zabbix-1.4.5/dbinit/data/data.sql
mysql -uzabbix -ppassword zabbix < /usr/share/doc/zabbix-1.4.5/dbinit/data/images_mysql.sql 

  1. Add zabbix ports to /etc/services:

cat >> /etc/services << EOF
zabbix_agent 10050/tcp
zabbix_trap 10051/tcp
EOF

  1. Make sure a couple of settings are correct in /etc/php/ini:

[Date]
; Defines the default timezone used by the date functions
date.timezone = Europe/London
max_execution_time = 300

  1. Add the MySQL password to /etc/zabbix/zabbix_server.conf

perl -pi -e 's/^#DBPassword.*/DBPassword=password/' /etc/zabbix/zabbix_server.conf

  1. Open ports 80, 10050, and 10051 on the firewall:

system-config-securitylevel-tui --port=80:tcp --port=10050:tcp --port=10051:tcp --quiet

  1. Start all the services and configure them to start at boot:

chkconfig zabbix on
chkconfig zabbix-agent on
chkconfig httpd on
service zabbix start
service zabbix-agent start
service httpd start

You should now be able to open a browser on http://server/zabbix and complete the initial configuration.

Optional step: If you need/want to use any SNMP tools (snmpwalk, etc.), you should install net-snmp-utils

Python logging with rich - writing to stderr - plain output when writing to file

Rich is a Python library for writing rich text (with color and style) to the terminal, and for displaying advanced content such as tables, markdown, and syntax highlighted code. Rich provides RichHandler , a logging handler for python's logging module which will format and colorize text written by the module. However, RichHandler writes to stdout by default. More specifically, it writes to a rich Console object which, by default, writes to stdout. To make RichHandler write to stderr by default, you must pass in a Console object which has been configured to write to stderr: import logging from rich.console import Console from rich.logging import RichHandler DATEFMT = "%Y-%m- %d T%H:%M:%SZ" FORMAT = " %(message)s " logging . basicConfig( level = "NOTSET" , format = FORMAT, datefmt = DATEFMT, handlers = [RichHandler(console = Console(stderr = True ))], ) logger = logging . getLogger(__name__) logger . i...

Fix python import order on save in vim with ruff and ale

My IDE of choice is vim. I use various tools to perform linting and code formatting, and configure them all with ALE  (the Asynchronous Lint Engine). After using several discrete tools ( black , isort , flake8 , etc) I have settled on using Ruff to do my python code formatting and linting. Here's the relevant fragment of my ALE config in my .vimrc: " ALE config let g :ale_fixers = { \ 'python' : [ 'ruff' , 'ruff_format' ], \} let g :ale_linters = { \ 'python' : [ 'ruff' ], \} let g :ale_python_ruff_use_global = 1 One of the last remaining wrinkles I had was getting Ruff to automatically sort import statements. Sorting imports is performed by the Ruff linter, not the formatter, which is documented here . The fix on the command line is to add an option, like this: ruff check --select I --fix The difficulty I had was getting this to happen in the editor when the file was saved. It turns out, all I needed to do was ...

Escaping special characters in wget username or password

I recently offered to help out with the hosting of a WordPress  site. It’s currently hosted somewhere with no shell access – just ftp – and there are a lot of images to transfer. I quickly figured out I could use wget to mirror the site, using something like: wget -m ftp://username:password@example.com However, this broke in this case because the username for the site contained an @ character (the username was user@example.com ). Turns out the solution was to encode the special chars using HTML notation. This is the command that did the trick: wget -m ftp://user%40example.com:password@example.com
