3. MySQL 8.0.28 Installation

Create the my.cnf file as shown at the end of this section.

yum install libaio -y

# Download MySQL minimal tarball
cd /packages
wget https://cdn.mysql.com/archives/mysql-8.0/mysql-8.0.28-linux-glibc2.17-x86_64-minimal.tar.xz
tar xvf mysql-8.0.28-linux-glibc2.17-x86_64-minimal.tar.xz
mv mysql-8.0.28-linux-glibc2.17-x86_64-minimal /usr/local/mysql

# Set PATH
echo 'export PATH=$PATH:/usr/local/mysql/bin:/usr/local/nginx/sbin' | tee -a /etc/profile
source /etc/profile

# Place my.cnf
vim /etc/my.cnf
# See sample configuration below

# Set ownership
chown mysql:mysql -R /data/mysql-cluster/mysql3306

# Initialize MySQL
/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql
# On error: rm -rf /data/mysql-cluster/mysql3306/data/* and retry

# Check error log (path from my.cnf)
cat /data/mysql-cluster/mysql3306/logs/error.log | grep -i error

# Install systemd service file and start
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/
/etc/init.d/mysql.server start
# Fix missing paths if needed:
mkdir /var/log/mariadb && touch /var/log/mariadb/mariadb.log && chown -R mysql:mysql /var/log/mariadb

# Retrieve temporary root password
ps -ef | grep mysql
cat /data/mysql-cluster/mysql3306/logs/error.log | grep root
# Example: A temporary password is generated for root@localhost: JLYwq)wga5kR

# Login and set up database
mysql -uroot -p

-- Change root password
ALTER USER root@localhost IDENTIFIED BY '123456';

-- Create Zabbix database and user
CREATE USER zabbix@localhost IDENTIFIED WITH mysql_native_password BY 'qaz123456';
CREATE DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_bin;
GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@localhost;
SET GLOBAL log_bin_trust_function_creators = 1;
FLUSH PRIVILEGES;
EXIT;

# Create alias for convenience
echo "alias dba3306='mysql -uroot -p123456'" >> /root/.bashrc
source /root/.bashrc
dba3306

Sample my.cnf:

[client]
port            = 3306
socket          = /data/mysql-cluster/mysql3306/tmp/mysqld3306.sock

[mysqld]
user = mysql
port            = 3306
socket          = /data/mysql-cluster/mysql3306/tmp/mysqld3306.sock
pid-file        = /data/mysql-cluster/mysql3306/tmp/my3306.pid
basedir         = /usr/local/mysql
datadir         = /data/mysql-cluster/mysql3306/data
slow_query_log_file = /data/mysql-cluster/mysql3306/logs/3306slow.log
log_error       = /data/mysql-cluster/mysql3306/logs/error.log
log_bin         = /data/mysql-cluster/mysql3306/binlogs/my3306_bin

echo $i;
?>
EOF
curl http://192.168.169.100/test.php
# Should output: 100

6. Zabbix Server and Agent Installation

# Download Zabbix 5.0.36 (use browser if wget fails)
cd /packages
wget https://cdn.zabbix.com/zabbix/sources/stable/5.0/zabbix-5.0.36.tar.gz
# Alternative: upload manually to /packages

tar zxvf zabbix-5.0.36.tar.gz -C /data/
cd /data/zabbix-5.0.36

# Install extra dependencies
yum install -y net-snmp-devel net-snmp-utils

# Compile and install
./configure --enable-server --enable-proxy --enable-agent --with-mysql=/usr/local/mysql/bin/mysql_config --with-net-snmp --with-libcurl
make install
echo $?  # Should be 0

# Create MySQL socket symlink for Zabbix
ln -s /data/mysql-cluster/mysql3306/tmp/mysqld3306.sock /tmp/mysql.sock

# Import database schema (run in order)
cd /data/zabbix-5.0.36/database/mysql/
mysql -uzabbix -p'qaz123456' zabbix < schema.sql
mysql -uzabbix -p'qaz123456' zabbix < images.sql
mysql -uzabbix -p'qaz123456' zabbix < data.sql

# Configure Zabbix server
vim /usr/local/etc/zabbix_server.conf
# Set:
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword='qaz123456'
DBPort=3306
Timeout=4

StatsAllowedIP=127.0.0.1

# Verify config (should show only non-commented, non-empty lines)
grep -v -E '^#|^$' /usr/local/etc/zabbix_server.conf

# Create library symlinks
ln -s /usr/local/mysql/lib/libmysqlclient.so.21 /usr/lib64
ln -s /usr/local/mysql/lib/private/libcrypto.so.1.1 /usr/lib64
ln -s /usr/local/mysql/lib/private/libssl.so.1.1 /usr/lib64

# Start Zabbix server
zabbix_server
netstat -nulpt | grep zabbix_server  # Expected port 10051

7. Prepare Zabbix Web Frontend

# Copy PHP UI files to Nginx document root
cp -a /data/zabbix-5.0.36/ui/* /usr/local/nginx/html
chmod -R 777 /usr/local/nginx/html
chown -R zabbix:mysql /usr/local/nginx/html/*

8. Web Setup
