前口上
世の中に落ちてるZabbix6.0の記事がなんか微妙に使いにくいので作成。
コンセプト的には、黙ってコマンドを打ちまくれば構築完成する手順にした。
1 環境
・AWS EC2
・RHEL／8.6
・MySQL／8.0.26
・Apache／2.4.37
2 構築
基礎情報確認
uname -a ; id -un
cat /etc/redhat-release
cat /etc/os-release
XXXXXXXXは好きなホスト名を記述。
ホスト名変更
hostnamectl set-hostname XXXXXXXX
もしくはnmtui
タイムゾーン設定
timedatectl
timedatectl set-timezone Asia/Tokyo
timedatectl
SELinuxは黙って無効化。
SELinux無効化
getenforce
cat /etc/selinux/config
sed -i -e 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
cat /etc/selinux/config
shutdown -r now
getenforce
アップデート
dnf update -y
Zabbix6.0インストール
rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-1.el8.noarch.rpm
dnf clean all
dnf -y install zabbix-server-mysql zabbix-web-mysql zabbix-web-japanese zabbix-apache-conf zabbix-sql-scripts
dnf -y install zabbix-agent2
DBPasswordだけ編集する。XXXXXXXXはパスワードを記述。
zabbix_server.conf
cat /etc/zabbix/zabbix_server.conf | grep DBPassword
cp -ip /etc/zabbix/zabbix_server.conf /etc/zabbix/zabbix_server.conf.`date +%Y%m%d`01
sed -i -e 's/# DBPassword=/DBPassword=XXXXXXXX/g' /etc/zabbix/zabbix_server.conf
cat /etc/zabbix/zabbix_server.conf | grep DBPassword
diff /etc/zabbix/zabbix_server.conf /etc/zabbix/zabbix_server.conf.`date +%Y%m%d`01
MySQLインストール
dnf -y install mysql-devel
dnf -y install mysql-server
mysql --version
mysql-server.cnf
cat /etc/my.cnf.d/mysql-server.cnf
echo innodb_file_per_table >> /etc/my.cnf.d/mysql-server.cnf
echo character_set_server=utf8mb4 >> /etc/my.cnf.d/mysql-server.cnf
echo collation_server=utf8mb4_bin >> /etc/my.cnf.d/mysql-server.cnf
echo skip-character-set-client-handshake >> /etc/my.cnf.d/mysql-server.cnf
echo performance_schema=0 >> /etc/my.cnf.d/mysql-server.cnf
echo log_timestamps=SYSTEM >> /etc/my.cnf.d/mysql-server.cnf
echo log_bin_trust_function_creators=1 >> /etc/my.cnf.d/mysql-server.cnf
cat /etc/my.cnf.d/mysql-server.cnf
systemctl -l status mysqld.service
systemctl enable --now mysqld
systemctl -l status mysqld.service
XXXXXXXXはパスワードを記述。何か聞かれたらyを打ちまくる作業。
MySQL installation
mysql_secure_installation
=======================================
Would you like to setup VALIDATE PASSWORD component?
Press y|Y for Yes, any other key for No: y
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0
New password: XXXXXXXX
Re-enter new password: XXXXXXXX
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
=======================================
systemctl restart mysqld.service
systemctl -l status mysqld.service
XXXXXXXXはパスワードを記述。
MySQL DB設定
mysql -uroot -pXXXXXXXX
=======================================
create database zabbix character set utf8mb4 collate utf8mb4_bin;
create user 'zabbix'@'localhost' identified by 'XXXXXXXX';
grant all privileges on zabbix.* to 'zabbix'@'localhost';
show databases;
quit;
=======================================
zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix
サービス起動
systemctl -l status zabbix-server php-fpm httpd | grep -E "(●|Active:)"
systemctl -l status zabbix-agent2 | grep -E "(●|Active:)"
systemctl enable --now zabbix-server php-fpm httpd
systemctl enable --now zabbix-agent2
systemctl -l status zabbix-server php-fpm httpd | grep -E "(●|Active:)"
systemctl -l status zabbix-agent2 | grep -E "(●|Active:)"
3 GUI接続・最終設定
構築されたEC2のアドレスに接続。画面に従って操作すれば完成。
xxx.xxx.xxx.xxx/zabbix
基本的にDBパスワードを入力し、ホスト名も入力して、タイムゾーンをAsia/Tokyoにするだけ。
