How to override open_basedir settings in Plesk

by

Plesk will overwrite any httpd.conf settings unless you include them in…

/home/httpd/vhosts/DOMAIN/conf/vhost.conf

basically, the instruction everywhere on the web on how to modify the open_basedir for plesk, so it won’t overwrite it, were all wrong…

here’s the instruction from the Plesk website:

http://kb.parallels.com/en/432

<Directory /home/httpd/vhosts/DOMAIN/httpdocs>
php_admin_value open_basedir “/home/httpd/vhosts/DOMAIN/httpdocs:/tmp:/usr/bin:/usr/local/bin”
</Directory>

this didn’t work because the the plesk httpd.include (which gets overwritten each time) used the “IfModule sapi_apache2.c” call, which MUST ALSO be used in the vhost.conf (which overrides)…

here is the correct way of inputing the vhost.conf:

<Directory /home/httpd/vhosts/DOMAIN/httpdocs>
<IfModule sapi_apache2.c>
php_admin_value open_basedir “/home/httpd/vhosts/DOMAIN/httpdocs:/tmp:/usr/bin:/usr/local/bin”
</IfModule>
</Directory>

Adding custom modules to apache for customapache : DirectAdmin

by

If you want to add any extra modules to apache, they’ll need to be compiled in. Any module that needs to be compiled in will have a –with-module type flag which will need to be used. To add this flag, run the following:

cd /usr/local/directadmin/customapache
vi configure.apache_ssl

#add your –with-module line to the end of the file,
# and make sure the character exists at the end of all lines except the last one.

./build clean
./build apache_mod_ssl

Then restart apache:
RedHat:

/sbin/service httpd restart

FreeBSD:

/usr/local/etc/rc.d/httpd restart

If you run into problems, you may also need to recompile php as well:

./build php

Then restart apache again.

SSH Authorized Keys Automatic Login

by

SSH can automatically authenticate connections when the client presents an authorized key. A client gives it’s public key to a server and then when it connects the server knows it’s allowed in and automatically allows the connection. The Keys are specific to users, so a key for user_a will not let user_b in.

Few Simple Steps

  1. Create Keys

    If the keys don’t exists already you must create them. Look in your ~/.ssh for files called id_rsa and id_rsa.pub. If those files don’t exist say ssh-keygen -b 2048 -t rsa to create them.

  2. Place Keys on Server

    Copy id_rsa.pub to the server then append that to ~/.ssh/authorized_keys

Optionally you can use a DSA key, simply replace `rsa` with `dsa` above

SSH automatic login assistance script

by

The script automatically pushes your SSH private key to the server specified so you can have automatic SSH,scp and sftp authentication. If you don’t have a key the script will generate one for you, also this script assumes that the user running the script has a home directory on the remote host. Should note that this script will only push the RSA encrypted key.

The Script

 

 

#!/bin/bash

# say: ./ssh_script.sh hostname

# Uploads your id_rsa.pub to the specified host, wrapped for readability

if [ ! -r ${HOME}/.ssh/id_rsa.pub ];then

ssh-keygen -b 2048 -t rsa

fi

# Append to the copy on the remote server

cat ~/.ssh/id_rsa.pub | ssh ${USER}@$1 “cat – >> .ssh/authorized_keys”

if [ $? -eq 0 ]; then

echo “Success”

fi

save the script say as  ssh_script.sh and execute it ./ssh_script.sh hostname

Virtuozzo glibc-dummy-centos-4 Error (1)

by

If you come across this error when trying to do a “yum update” on your Virtuozzo Virtual Dedicated Server

–> Processing Dependency: glibc-common = 2.3.4-2.25 for package: glibc-dummy-centos-4–> Finished Dependency ResolutionError: Missing Dependency: glibc-common = 2.3.4-2.25 is needed by package glibc-dummy-centos-4

You can make use of the following steps to fix the problem. First you need to remove the package that is causing the problem.

yum remove glibc-dummy-centos-4

After you have removed that package you need to reinstall gcc with all the extras. You can do that simply by running the following command.

yum install gcc & yum install gcc*

If everything installed correctly you should now be able to run a yum update and it should not error out at all.

Enable SLM on Virtuozzo

by

 What is SLM, “Virtuozzo Service Level Management (SLM) is a system that maintains and allows administrators to configure and control the levels of service (i.e., the set of ‘promises’) provided to VPS owners.”I came across some different ways of enabling SLM on the Virtuozzo Node, by far the best was the information about how to enable it with out a Node reboot. run the following commands. Edit the following files and make said changes

/etc/sysconfig/vz and change the SLM entry to slm=yes/etc/sysconfig/vzagent/vzagent.conf Locate the SLM entry, change it to 1. 

 

After you modified configuration file you need to restart VZAgent, use the following command on a hardware node:

vzagent_ctl restart
