Kloxo with Nginx or Nginx-Proxy

by asep on January 29, 2013

If you love Kloxo as your Web Control Panel and want to running Nginx as Webserver or want to running Nginx as Proxy, you can Install Kloxo-MR (aka ‘Kloxo for by Mustafa Ramadhan’).

How to install:

1. pre-install — better for fresh install

cd /
# update centos to latest version
yum update -y
# install some packages like package-cleanup, etc
yum install yum-utils yum-priorities vim-minimal subversion curl zip unzip -y
yum install telnet -y

setenforce 0
echo 'SELINUX=disabled' &gt; /etc/selinux/config

yum update -y

# install some packages like package-cleanup, etc

yum install yum-utils yum-priorities vim-minimal subversion curl zip unzip -y

yum install telnet -y

setenforce 0

echo 'SELINUX=disabled' > /etc/selinux/config

2. Install/reinstall/upgrade — data not destroyed with this fork – for existing kloxo (6.1.x), run ‘sh /script/update’ first.

# delete if exist
rm -rf /tmp/kloxo

# create kloxo temp dir
mkdir /tmp/kloxo ; cd /tmp/kloxo

# get kloxo packer from github
wget https://github.com/mustafaramadhan/kloxo/raw/dev/kloxo-install/kloxo-packer.sh --no-check-certificate

# get kloxo fork from github
sh kloxo-packer.sh --fork=mustafaramadhan --branch=dev

# install kloxo
sh kloxo-installer.sh --type=master

# better reboot
reboot

# get kloxo packer from github

wget https://github.com/mustafaramadhan/kloxo/raw/dev/kloxo-install/kloxo-packer.sh --no-check-certificate

# get kloxo fork from github

sh kloxo-packer.sh --fork=mustafaramadhan --branch=dev

# install kloxo

sh kloxo-installer.sh --type=master

# better reboot

reboot

To switch from Apache to be Nginx Webserver just login into kloxo and find Switch Program at Home.

TIPS: To ‘save’ memory if you use Kloxo-MR

Convert mysql to MyISAM engine by running ‘sh /script/mysql-convert –engine=myisam’
Select php-fpm_event on php-type in ‘webserver config’ and can also be enabled on the ‘secondary php’
Select php53u on ‘php branch’ in ‘webserver config’ as php-fpm is problematic with php52
Keep a minimum amount of ‘customer’ and if it might be enough ‘admin’ alone
remove clamav with ‘yum remove * freshclam clamav *’

by asep on January 27, 2013

If you already trying to setup an OpenBSB Webserver using Apache + MySql + PHP, and now you want to replace the apache webserver with Nginx, you can follow the follong tutorial:

Step 1: Remove Apache Webserver

To remove apache webserver:

# pkg_delete apache-httpd-2.2.22
apache-httpd-2.2.22: ok
Read shared items: ok
--- -apache-httpd-2.2.22 -------------------
You should also run /usr/sbin/userdel _apache2
You should also run /usr/sbin/groupdel _apache2

# pkg_delete apache-httpd-2.2.22

apache-httpd-2.2.22: ok

Read shared items: ok

--- -apache-httpd-2.2.22 -------------------

You should also run /usr/sbin/userdel _apache2

You should also run /usr/sbin/groupdel _apache2

# /usr/sbin/userdel _apache2
# /usr/sbin/groupdel _apache2

1 2	# /usr/sbin/userdel _apache2 # /usr/sbin/groupdel _apache2

Step 2: Installing Nginx

# pkg_add nginx
Ambiguous: choose package for nginx
 a       0:
         1: nginx-1.0.15
         2: nginx-1.0.15-passenger
Your choice: 1
nginx-1.0.15: ok

a 0:

1: nginx-1.0.15

2: nginx-1.0.15-passenger

Your choice: 1

nginx-1.0.15: ok

Step 3: Intstaling PHP-FPM

# pkg_add php-fpm
php-fpm-5.3.14p0: ok
The following new rcscripts were installed: /etc/rc.d/php_fpm
See rc.d(8) for details.

4

# pkg_add php-fpm

php-fpm-5.3.14p0: ok

The following new rcscripts were installed: /etc/rc.d/php_fpm

See rc.d(8) for details.

Step 4: Start ONMP services automatically

# nano /etc/rc.conf.local

1	# nano /etc/rc.conf.local

put the following lines:

mysqld_flags=""
pkg_scripts="mysqld nginx php_fpm"

1 2	mysqld_flags="" pkg_scripts="mysqld nginx php_fpm"

Step 5: Setting Up Nginx

Edit /etc/nginx/nginx.conf and add “index.php” to the line that has the other index files. The config block should look like this, but you can alter the order if you wish.

location / {
            root   /htdocs;
            index  index.html index.htm <a href="http://www.info-vijesti.com/">index</a>.php;
        }

1

2

3

4

location / {

root /htdocs;

index index.html index.htm <a href="http://www.info-vijesti.com/">index</a>.php;

}

Uncomment the following block of configuration to enable nginx to forward PHP requests to php-fpm.

        location ~ .php$ {
            root           /htdocs;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /htdocs$fastcgi_script_name;
            include        fastcgi_params;
        }

location ~ .php$ {

root /htdocs;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /htdocs$fastcgi_script_name;

include fastcgi_params;

}

Step 6: Reboot OpenBSD

Once everything is installed and configured to start automatically, reboot to make sure everything starts up as expected.

Step 7: Testing

Create phpinfo file:

echo "" | sudo tee /var/www/htdocs/phpinfo.php

1	echo "" \| sudo tee /var/www/htdocs/phpinfo.php

Open phpinfo script:

http://your-OpenBSD-ip-address/phpinfo.php

1	http://your-OpenBSD-ip-address/phpinfo.php
