IP:allow,RELAYCLIENT=”",RBLSMTPD=”",NOP0FCHECK=”0″,DKSIGN=”/var/qmail/control/domainkeys/domain.com/dkim1″

Where IP is the IP of your remote email server. You can even specify something like : aaa.bbb.ccc.:allow,RELAYCLIENT=”"

After this you have to run :

tcprules /etc/tcprules.d/tcp.smtp.cdb /etc/tcprules.d/tcp.smtp.tmp < /etc/tcprules.d/tcp.smtp

http://us.php.net/distributions/php-5.2.17.tar.gz

http://php-fpm.org/downloads/php-5.2.17-fpm-0.5.14.diff.gz

http://nginx.org/download/nginx-1.1.0.tar.gz

Then run :

tar -xvzf php-5.2.17.tar.gz
gzip -cd php-5.2.17-fpm-0.5.14.diff.gz | sudo patch -d php-5.2.17 -p1
cd php-5.2.17

make all install

Note that you can add –prefix to install the binaries in a different location than the default one.

After compilation is done :

strip /usr/local/bin/php-cgi
cp sapi/cgi/fpm/php-fpm /etc/init.d/
chmod +x /etc/init.d/php-fpm

cp /usr/src/php-5.2.17/php.ini-recommended /usr/local/lib/php.ini
mkdir /etc/php/
ln -s /usr/local/lib/php.ini /etc/php/php.ini
ln -s /usr/local/etc/php-fpm.conf /etc/php/php-fpm.conf


Make sure you edit /etc/php/php-fpm.conf and set the proper user/group (and permissions if its the case).

Then compile Nginx:

tar zxvf nginx-1.1.0.tar.gz
./configure --sbin-path=/usr/local/sbin --with-http_ssl_module --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module --with-http_stub_status_module
make && sudo make install


The same you can modify the –prefix here.

On older Plesk version (

websrvmng –set-http-port –port=8080

Starting with Plesk 10 this is not so easy since you have to edit a php file called /usr/local/psa/admin/conf/templates/default/domain/domainVirtualHost.php. In my case instead of :

domain->physicalHosting->ipAddress->address ?>:server->webserver->httpsPort : $VAR->server->webserver->httpPort ?>>
ServerName "domain->asciiName ?>:server->webserver->httpsPort : $VAR->server->webserver->httpPort ?>"

I’ve set :

<VirtualHost <?php echo $OPT['ipAddress']->escapedAddress ?>:<?php echo $OPT['ssl'] ? 8043 : 8080 ?>>
ServerName “<?php echo $VAR->domain->asciiName ?>:<?php echo $OPT['ssl'] ? 8043 : 8080 ?>”

Where 8043 will be the new https port and 8080 will be the http port.

After this change I had to run :

/usr/local/psa/admin/bin/httpdmng –reconfigure-all

Note that this is only for Plesk 10.x. On 9.x we used to have

/usr/local/psa/admin/sbin/websrvmng –reconfigure-all

After this make sure that the Apache server has set in its configuration files (/etc/httpd/conf/httpd.conf) Listen 8080 instead of Listen 80. Same thing for the /etc/httpd/conf.d/ssl.conf file, Listen 8043 instead of Listen 443.

Then you need to install nginx (yum install nginx) and download this zip file that these guys provided http://www.grafxsoftware.com/download/nginx/nginx_setup.zip. Furthermore you can check their http://www.grafxsoftware.com/faq.php/HOW-TO-configure-PLESK-with-NGinx-proxy-reverse/1/1/.

Once downloaded run:

sh generate_nginx_conf.sh

Verify with “nginx -t” that there isn’t any error and finally restart the involved services :

service httpd restart
service nginx restart

Make sure that 8043 and 8080 accept connections. (Note that its not necessary to change the https port).

xe vm-disk-add disk-size=5GiB vm=node1

Then in node1 if you do “cat /proc/partitions” you should see the new storage.

On the server run:

apt-get install puppetmaster

At the time I’m writing this in the repos version 2.6.1 is available.

On the client run :

apt-get install puppet

Note that /etc/hosts needs to contain the IP and host of both client and server, e.g:

10.0.0.30 depot.server.org depot
10.0.0.31 n1.server.org n1


Create a default manifest file (/etc/puppet/manifests/site.pp) and put in it :


class test_class {
file { "/tmp/test":
ensure => present,
mode => 644,
owner => root,
group => root
}
}

# tell puppet on which client to run the class
node n1 {
include test_class
}


Then on the server run :

/etc/init.d/puppetmaster start

and on client :

puppetd –server depot.server.org –waitforcert 60 –test

After this you should see on the server a new host when running :

puppetca –list

In order to sign this host on the server side you need to run :

puppetca –sign n1.server.org

After this on the client side /tmp/test should be created.

do-release-upgrade -d

For CentOS 32 bit run:

xe vm-clone uuid=`xe template-list name-label=Red\ Hat\ Enterprise\ Linux\ 6\ \(32-bit\) –minimal` new-name-label=”CentOS 6.0 (32-bit)”

For CentOS 64 bit run:

xe vm-clone uuid=`xe template-list name-label=Red\ Hat\ Enterprise\ Linux\ 6\ \(64-bit\) –minimal` new-name-label=”CentOS 6.0 (64-bit)”

Run:

xe template-list name-label=CentOS\ 5.6\ \(32-bit\)
And remember the uuid:
uuid ( RO) : 0ce71430-d7ef-00f8-07d9-4166953c4f19

Then:

xe template-param-set other-config:default_template=false uuid=0ce71430-d7ef-00f8-07d9-4166953c4f19

Then :

xe template-param-set is-a-template=false uuid=0ce71430-d7ef-00f8-07d9-4166953c4f19

And then:

xe vm-destroy uuid=0ce71430-d7ef-00f8-07d9-4166953c4f19

#passwd user
Authentication Token Manipulation Error
#

This error is being produced because you are using shadowed password files and the shadow doesn’t have entry for this user. i.e, passwd file has an entry for this user, but shadow file doesn’t.

In order to resolve this, you can either add the entry manually or recreate the shadow file. You can use pwconv to recreate the shadow file. See the manpage for more details on this.
