私はMariaDBモニターが欲しいですmonit tools。私monit scriptのもの：
check process mariadb_pid with pidfile /var/lib/mysql/db1.pid
check program telnet with path "/root/telnet.sh"
if status eq 99 then exec "/usr/bin/systemctl restart mariadb.service"
そしてtelnet script：
#!/bin/bash
cat /root/ips | \
while read host port; do
result=$(bash -c 'exec 3<> /dev/tcp/'$host'/'$port';echo $?' 2>/dev/null)
echo $result
if [ "$result" != "0" ]; then
exit 99
fi
done
ipsファイルは次のようになります。
192.168.10.10 3306
192.168.10.20 3306
これで、ipsファイルのmariadb ip1とip2が閉じられたときに実行されることが予想されます。
if status eq 99 then exec "/usr/bin/systemctl restart mariadb.service"
でも走らないでください。監視ログを確認してください。
