Compile Zabbix 5.4 in Ubuntu 21.10

Step 1: Compile Zabbix 5.4 in Ubuntu 21.10.md

Install required packages

1. apt-get update
2. apt-get install git libpcre2-8-0 wget build-essential automake pkg-config autoconf autogen vim libmysqlclient-dev libxml2-dev libsnmp-dev libssh2-1-dev libopenipmi-dev libevent-dev libcurl4-openssl-dev libpcre3-dev unixodbc-dev golang-go openjdk-17-jdk libldap2-dev libgnutls28-dev libmodbus-dev libmysqlclient-dev net-tools

Compile Zabbix from source

1. wget https://cdn.zabbix.com/zabbix/sources/stable/5.4/zabbix-5.4.7.tar.gz
2. tar xvfz zabbix-5.4.7.tar.gz
3. cd zabbix-5.4.7
4. ./configure --enable-server --enable-agent --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2 --with-openipmi --with-ssh2 --with-unixodbc --enable-proxy --enable-java --enable-webservice --enable-ipv6 --with-ldap --enable-agent2 --with-openssl --with-libmodbus --prefix=/var/lib/zabbix
5. make
6. make install
7. Copy Zabbix UI (Web Interface) cp -Rfv ~/zabbix-5.4.7/ui/ /var/lib/zabbix_ui

Install zabbix-server SystemD Service

1. sudo addgroup --system --quiet zabbix

2. sudo adduser --quiet --system --disabled-login --ingroup zabbix --home /var/lib/zabbix --no-create-home zabbix

3. sudo mkdir -m u=rwx,g=rwx,o= -p /var/lib/zabbix

4. sudo chown zabbix:zabbix /var/lib/zabbix

5. Create the service zabbix-server in SystemD

   sudo tee /etc/systemd/system/zabbix-server.service <<EOF
   [Unit]
   Description=Zabbix Server (MySQL/MariaDB)
   Documentation=man:zabbix_server
   After=network.target mysql.service
   
   [Service]
   Type=simple
   User=zabbix
   Group=zabbix
   ExecStart=/var/lib/zabbix/sbin/zabbix_server --foreground
   ExecReload=/var/lib/zabbix/sbin/zabbix_server -R config_cache_reload
   Restart=always
   
   [Install]
   WantedBy=multi-user.target
   EOF
   

6. Configure Server Conf file: /var/lib/zabbix/etc/zabbix_server.conf

   Example: Configuration File Options

   LogType=file
   LogFile=/tmp/zabbix_server.log
   ListenIP=127.0.0.1
   ListenPort=9997
   DebugLevel=3
   DBHost=localhost
   DBName=zabbix
   DBUser=zabbix
   DBPassword=xuechae1wahc8Jee8ceeni
   StartPollers=10
   StartPreprocessors=10
   StartPollersUnreachable=10
   StartPingers=10
   StartDiscoverers=10
   StartHTTPPollers=10
   StartTimers=10
   StartAlerters=10
   CacheSize=500M
   StartDBSyncers=4
   HistoryCacheSize=160M
   HistoryIndexCacheSize=114M
   TrendCacheSize=114M
   Timeout=4
   LogSlowQueries=3000
   StartLLDProcessors=10
   StatsAllowedIP=127.0.0.1
   StartReportWriters=2
   WebServiceURL=http://localhost:9998/report
   

7. sudo systemctl daemon-reload

8. sudo systemctl start zabbix-server

9. sudo systemctl enable zabbix-server

10. Verify: sudo systemctl status -l zabbix-server

Notes

1. GnuTLS is not compatible with zabbix-agent2
2. Proceed with the Database Configuration to be used by Zabbix-Server
3. Adjust the Zabbix-Server configuration file: vim /var/lib/zabbix/etc/zabbix_server.conf
4. Check the Zabbix-Server log file: tail -f /tmp/zabbix_server.log

Step 2: Create Zabbix 5.4 Database.md

Install MySQL Server

1. sudo apt-get install mariadb-server mariadb-common

Create Database Credentials

1. mysql -uroot -p<password>
2. create database zabbix character set utf8 collate utf8_bin;
3. create user 'zabbix'@'localhost' identified by '<password>';
4. grant all privileges on zabbix.* to 'zabbix'@'localhost';
5. flush privileges;
6. quit;

Import Zabbix Schema

1. mysql -uzabbix -p<password> zabbix < ~/zabbix-5.4.7/database/mysql/schema.sql
2. mysql -uzabbix -p<password> zabbix < ~/zabbix-5.4.7/database/mysql/images.sql
3. mysql -uzabbix -p<password> zabbix < ~/zabbix-5.4.7/database/mysql/data.sql

Step 3: Install Zabbix-UI with Nginx.md

By default Ubuntu 21.10 will install PHP 8.0

Install Packages

1. sudo apt -y install software-properties-common
2. sudo add-apt-repository ppa:ondrej/php
3. sudo apt update
4. sudo apt-get install php7.4 php7.4-fpm php7.4-cli php7.4-json php7.4-common php7.4-ldap php7.4-mysql php7.4-zip php7.4-gd php7.4-mbstring php7.4-curl php7.4-xml php7.4-bcmath php-pear php7.4-amqp php7.4-zmq nginx
5. sudo systemctl stop apache2
6. sudo systemctl disable apache2
7. sudo systemctl restart php7.4-fpm
8. sudo systemctl enable nginx
9. sudo systemctl start nginx

Configure VirtualHost

1. Create the file /etc/nginx/sites-enabled/zabbix with the content

   server {
        listen 80;
        root /var/lib/zabbix_ui;
        index index.php index.html index.htm index.nginx-debian.html;
        server_name 41013e43741c.mylabserver.com;
        server_name monitor.truckspyinfra.com;
        if ($request_uri ~ "^[^?]*?//") {
            rewrite "^" $scheme://$host$uri permanent;
        }
        location / {
                try_files $uri $uri/ =404;
        }
        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        }
   }
   

   Replace 41013e43741c.mylabserver.com with your ServerName
2. Tune-up /etc/php/7.4/fpm/php.ini and restart php-fom with: sudo systemctl restart php7.4-fpm
3. nginx -t
4. sudo systemctl restart nginx

Step 4: Install Zabbix Agent2

### Ubuntu

Step 5: Install Zabix Web Service.md

Install Required Packages

1. sudo curl -sS -o - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add
2. sudo bash -c "echo 'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main' >> /etc/apt/sources.list.d/google-chrome.list"
3. sudo apt install google-chrome-stable

Install the Service

1. Create zabbix-webservice service in SystemD

sudo tee /etc/systemd/system/zabbix-webservice.service <<EOF
  [Unit]
  Description=Zabbix Web Service
  After=network.target mysql.service

  [Service]
  Type=simple
  User=zabbix
  Group=zabbix
  ExecStart=/var/lib/zabbix/sbin/zabbix_web_service -c /var/lib/zabbix/etc/zabbix_web_service.conf
  Restart=always

  [Install]
  WantedBy=multi-user.target
EOF

2. Configure WebService Conf file: /var/lib/zabbix/etc/zabbix_web_service.conf

   Example: Configuration File Options

   LogType=console
   DebugLevel=4
   AllowedIP=127.0.0.1,::1
   ListenPort=9998
   

3. Enable service: sudo systemctl enable zabbix-webservice

4. Start service: sudo systemctl start zabbix-webservice
