This tutorial is how to make a Web Server under Debian 6 using Nginx web server, MySQL as a database server, PHP-FPM as a fastCGI server, APC as an optcode cache and Varnish as a caching proxy to optimize a website using wordpress.
I have tried this method using Debian 6.0.5 32BIT on XEN VPS with 512 Memory.
Step 1: Adding main debian repos
Because i’m using idROOT as Indonesia VPS Provider, so i’m using Indonesian repository which is located at Kambing.ui.ac.id
|
|
deb http://kambing.ui.ac.id/debian/ squeeze main contrib non-free deb http://kambing.ui.ac.id/debian/ squeeze-updates main contrib non-free deb http://kambing.ui.ac.id/debian-security/ squeeze/updates main contrib non-free |
Step 2: Adding dot-deb repo
|
|
# echo deb http://packages.dotdeb.org stable all >> /etc/apt/sources.list # echo deb-src http://packages.dotdeb.org stable all >> /etc/apt/sources.list # wget http://www.dotdeb.org/dotdeb.gpg # cat dotdeb.gpg | apt-key add - |
Step 3: Update and adding base software
|
|
# apt-get update && apt-get upgrade # apt-get install nano sudo curl lsb-release |
Step 4: Adding Varnish repo and Install Varnish
|
|
# curl http://repo.varnish-cache.org/debian/GPG-key.txt | apt-key add - # echo "deb http://repo.varnish-cache.org/debian/ $(lsb_release -s -c) varnish-3.0" >> /etc/apt/sources.list.d/varnish.list # apt-get update # apt-get install varnish |
Step 5: Adding a system user and Add user to sudo
find: root ALL and then add this line below : [USER] ALL=(ALL) ALL
Step 5: Installing Software
|
|
# apt-get install nginx mysql-server mysql-client memcached php5 php-apc php-auth php-net-smtp php-net-socket php-pear php5-curl php5-gd php5-mcrypt php5-mysql php5-fpm php5-memcached php5-tidy |
Step 6: Configuring MySql
|
|
# mv /etc/mysql/my.cnf /etc/mysql/my.cnf.bak # nano /etc/mysql/my.cnf |
Insert this code into /etc/mysql/my.cnf

Step 6: Configuring nginx
|
|
# mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak # nano /etc/nginx/nginx.conf |
Insert this code into /etc/nginx/nginx.conf
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 |

Step 7: Fix CGI Path Info
|
|
# nano /etc/php5/fpm/php.ini |
find cgi.fix_pathinfo and Uncomment the command by removing the ; in front and replace the defauly 1 with a 0!
Step 8: Configuring PHP5-FPM

|
|
# mv /etc/default/varnish /etc/varnish/default.bak # nano /etc/default/varnish |
Insert this code into /etc/default/varnish
|
|
START=yes NFILES=131072 MEMLOCK=82000 DAEMON_OPTS="-a :80 -T localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s malloc,1G" |
|
|
mv /etc/varnish/default.vcl /etc/varnish/default.vcl.bak nano /etc/varnish/default.vcl |
Insert this code into /etc/varnish/default.vcl
|
|
backend default { .host = "localhost"; .port = "8080"; } acl purge { "localhost"; } sub vcl_recv { if (req.request == "PURGE") { if (!client.ip ~ purge) { error 405 "Not allowed."; } return(lookup); } if (req.url ~ "^/$") { unset req.http.cookie; } } sub vcl_hit { if (req.request == "PURGE") { set obj.ttl = 0s; error 200 "Purged."; } } sub vcl_miss { if (req.request == "PURGE") { error 404 "Not in cache."; } if (!(req.url ~ "wp-(login|admin)")) { unset req.http.cookie; } if (req.url ~ "^/[^?]+.(jpeg|jpg|png|gif|ico|js|css|txt|gz|zip|lzma|bz2|tgz|tbz|html|htm)(?.|)$") { unset req.http.cookie; set req.url = regsub(req.url, "?.$", ""); } if (req.url ~ "^/$") { unset req.http.cookie; } } sub vcl_fetch { if (req.url ~ "^/$") { unset beresp.http.set-cookie; } if (!(req.url ~ "wp-(login|admin)")) { unset beresp.http.set-cookie; }} |
step 10: Securing VPS
Securing SSH
|
|
# nano /etc/ssh/sshd_config |
–find: PermitRootLogin yes
–change to: PermitRootLogin no
–find: X11Forwarding yes
–change to: X11Forwarding no
–find: Port 22
–change to: 7766
–add to end: UseDNS no
Restart SSH
Installing IPTABLES
|
|
# apt-get install iptables |
// Show what is loaded in our firewall
// Flush everything we have in our firewall
// Allow established sessions
|
|
# iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT |
// Allow services
|
|
iptables -A INPUT -p tcp --dport 7766 -j ACCEPT iptables -A INPUT -p tcp --dport 80 -j ACCEPT iptables -A INPUT -p tcp --dport 8080 -j ACCEPT iptables -A INPUT -p tcp --dport 9000 -j ACCEPT iptables -A INPUT -p tcp --dport 12000:12100 -j ACCEPT |
// End iptables by blocking everything that we didn’t explicitly allowed earlier
|
|
iptables -A INPUT -j DROP |
// backup iptables to a file
|
|
iptables-save > /home/[USER]/iptables.rules |
Making sure iptables rules are reloaded on reboot
|
|
# nano /etc/network/if-up.d/iptables |
Insert this code
|
|
#!/bin/sh iptables-restore < /home/[USER]/iptables.rules |
|
|
# chmod +x /etc/network/if-up.d/iptables |
Restartig our services
|
|
# service mysql restart # service memcached restart # service varnish restart # service nginx restart # /etc/init.d/php5-fpm restart |
