wget http://www.configserver.com/free/csf.tgz
tar zxvf csf.tgz
cd csf
yum install perl-libwww-perl perl-Time-HiRes perl iptables -y
sh install.sh
sed -i 's/TESTING = "1"/TESTING = "0"/g' /etc/csf/csf.conf
sed -i 's/ICMP_IN = "1"/ICMP_IN = "0"/g' /etc/csf/csf.conf
sed -i 's/DENY_IP_LIMIT = "100"/DENY_IP_LIMIT = "500"/g' /etc/csf/csf.conf
sed -i 's/DENY_TEMP_IP_LIMIT = "100"/DENY_TEMP_IP_LIMIT = "500"/g' /etc/csf/csf.conf
perl /etc/csf/csftest.pl

cd /usr/local/directadmin/custombuild
./build set webserver nginx_apche
./build set php1_mode php-fpm
./build set php1_release 5.4
./build set php2_mode no
./build set zend yes
./build set ioncube yes
./build set mod_ruid2 no
./build all #时间可能有点略长
./build rewrite_confs
./build secure_php

echo "kernel.msgmni = 1024">>/etc/sysctl.conf
echo "kernel.sem = 250 256000 32 1024">>/etc/sysctl.conf
sysctl -p
reboot #改完需重启

下载这个,然后解压丢到/etc/cron.hourly

chmod 755 /etc/cron.hourly/ipcs_check
bash /etc/cron.hourly/ipcs_check

chmod 755 /etc/cron.hourly/ipcs_check
bash /etc/cron.hourly/ipcs_check
开启共享IP允许使用SSL

echo "enable_ssl_sni=1">>/usr/local/directadmin/conf/directadmin.conf
