Buatlab webserver untuk subdomain "x".inilab.net (195.109.14.100/26). Webserver yg anda buat nantinya akan difungsikan sebagai web blog.

NB : x disesuaikan dengan nama server anda.

penyelesaian

1. Setup IP Address

# ifconfig eth2 195.109.14.100 netmask 255.255.255.192 broadcast 195.109.14.191

2. Buat script kompilasi untuk webserver (nginx)

# pico nginx.sh

>#!/bin/bash

ver=1.4.3

tar -zxvf nginx-$ver.tar.gz

test ! -d /var/tmp/fastcgi && mkdir /var/tmp/fastcgi

test ! -d /var/tmp/body && mkdir /var/tmp/body

echo \"Direktori-nya sudah ada\"

cd nginx-$ver

./configure --prefix=/usr/local/nginx \\

--user=nobody --group=nobody \\

--http-fastcgi-temp-path=/var/tmp/fastcgi \\

--http-client-body-temp-path=/var/tmp/body \\

--with-perl=/usr/bin/perl \\

--with-pcre

make

make install

test ! -d /usr/local/nginx/conf/vhost && mkdir /usr/local/nginx/conf/vhost

echo \"Direktori-nya sudah ada\"

chmod 700 /var/tmp/body

chmod 700 /var/tmp/fastcgi

chown -R nobody:root /var/tmp/body

chown -R nobody:root /var/tmp/fastcgi

cd /usr/local/src

3. Install WebServer (nginx)

# chmod 755 nginx.sh

# ./nginx.sh

4. Konfigurasi WebServer

- Edit nginx.conf

# pico /usr/local/nginx/conf/nginx.conf

user nobody nobody;

worker_processes 2;

error_log logs/error.log;

pid logs/nginx.pid;

events {

use epoll;

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

log_format main \'$remote_addr - $remote_user [$time_local] $request \'

\'\"$status\" $body_bytes_sent \"http_referer\" \'

\'\"$http_user_agent\" \"$http_x_forwarded_for\" \';

tcp_nopush off;

tcp_nodelay on;

keepalive_timeout 15;

server_tokens off;

include vhost/web.conf;

}

- Buat file konfigurasi untuk VirtualHost

# pico /usr/local/nginx/conf/vhost/web.conf

server {

listen 80;

server_name teguh.inilab.net;

access_log /home/logs/teguh.inilab.log combined;

root /home/web; # <---- ganti dengan nama folder yg sesuai

index index.php index.html index.htm;

location / {

try_files $uri $uri/ /index.php?q=$uri&$args;

}

error_page 500 502 503 504 /50x.html;

location /50x.html {

root html;

}

location ~ \\.php$ {

fastcgi_pass 127.0.0.1:9001;

fastcgi_index index.php;

include fastcgi_params;

}

location ~ /.ht {

deny all;

}

- Buat direktori untuk Data WebServer

# mkdir /home/web

# chown -R root:nobody /home/web

- Buat direktori untuk log VirtualHost

# mkdir /home/logs

- Buat file index.php

# pico /home/web/index.php

<?php

phpinfo();

- Edit file /usr/local/nginx/conf/fastcgi_params

# pico /usr/local/nginx/conf/fastcgi_params

fastcgi_param QUERY_STRING $query_string;

fastcgi_param REQUEST_METHOD $request_method;

fastcgi_param CONTENT_TYPE $content_type;

fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param PATH_INFO $fastcgi_script_name;

fastcgi_param SCRIPT_NAME $fastcgi_script_name;

fastcgi_param REQUEST_URI $request_uri;

fastcgi_param DOCUMENT_URI $document_uri;

fastcgi_param DOCUMENT_ROOT $document_root;

fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param REMOTE_ADDR $remote_addr;

fastcgi_param REMOTE_PORT $remote_port;

fastcgi_param SERVER_ADDR $server_addr;

fastcgi_param SERVER_PORT $server_port;

fastcgi_param SERVER_NAME $server_name;

fastcgi_param REDIRECT_STATUS 200;

5. Start WebServer

# /usr/local/nginx/sbin/nginx

6. Buat script kompilasi untuk PHP

# pico php.sh

#!/bin/bash

ver=5.3.27

test -d php-$ver && rm -rf

tar -zxvf php-$ver.tar.gz

cd php-$ver

./configure --prefix=/usr/local/php \\

--with-curl --with-mysql --with-pcre-regex \\

--with-gd --with-zlib --with-openssl \\

--with-gmp --with-jpeg-dir --with-mysql-sock \\

--with-config-file-path=/usr/local/php/etc \\

--with-fpm-user=nobody --with-fpm-group=nobody \\

--enable-fpm --enable-sockets --enable-mbstring \\

--enable-sysvmsg --enable-sysvshm --enable-sysvsem \\

--disable-magic-quotes --disable-ipv6
