[mpm_prefork:error] [pid 1265] AH00161: server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting
vim /etc/apache2/mods-enabled/mpm_event.conf
MaxRequestWorkers 300
ServerLimit 300
2. Xác định IP DDOS attack bằng cách dùng: 1.
netstat -an | egrep ':80|:443' | grep ESTABLISHED | awk '{print $5}' | grep -o -E "([0-9]{1,3}[.]){3}[0-9]{1,3}" | sort -n | uniq -c | sort -nr
Kết quả sẽ đại khái như:
370 113.23.24.54 3 171.247.198.211 3 115.78.166.221 1 116.102.223.146
2. Tạo fail2ban https://www.maketecheasier.com/fail2ban-protect-apache-ddos/ 3. Ban ip: sudo fail2ban-client set apache banip 192.168.1.20 Ngoài ra có thể dùng ufw đề quản lý chặn IP cũng sẽ dễ hơn
Vào view log apache thì thấy báo:
[mpm_prefork:error] [pid 1265] AH00161: server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting
vim /etc/apache2/mods-enabled/mpm_event.confTăng:ServerLimit 300
