That’s All..!! 

Xen VMs use lvms and extending disk space from SolusVM control panel may
not work properly. So, we will need to extend the lvm manually.

Shutdown VM from SolusVM control panel or use the following command on node :

# xm shutdown vm_ID 

(Replace vm_id with the xen ID of the VPS)

Extend LVM :

# lvextend /dev/Xen/vm_ID_img -L +50G 

(This will increase the main disk size for vm by 50G)

Checking File System for errors :

# e2fsck -f /dev/vg0/vm_ID_img 

Resize File System :

# resize2fs /dev/vg0/vm1_ID_img 

(This will increase the disk’s filesystem to the maximum new amount)

Boot up the VM:

# xm create vm_ID /home/xen/vm_ID/vm_ID.cfg 

Done..!! Now check the VPS Disk Space using df command.

If you get the message while browsing php info page, it means that
phpinfo function is disabled. To resolve this you will have to :

Remove phpinfo from disable_functions in php.ini

To locate php.ini file, use command :

Check the line Loaded Configuration File: for php.ini location. Remove phpinfo  from disable_functions in php.ini and save it.

Now check the phpinfo page..!! 

If you forget or lose your SolusVM Admin password, you can change it using SolusVM php script.
Log into SolusVM master server via SSH. Then you can reset the admin password by running the below command :

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change 
--username=<ADMINUSERNAME>

For username mention the admin username for SolusVM , the default Admin username is vpsadmin.
You will get an output similar to this:

New password: Wc7Q0EbVFUasJ4j

Done..!! Now you can log into SolusVM server with the new password.

Add the following to /etc/my.cnf file to enable the slow query log:

log-slow-queries=/var/lib/mysql/slow.log

After that, then do the following commands to create the file with the right ownership and file permissions:

touch /var/lib/mysql/slow.log

chmod 660 /var/lib/mysql/slow.log

chown mysql:mysql /var/lib/mysql/slow.log

Done..!! I hope that was too easy.. 

CSF requires at least these iptables modules to work properly :
ip_tables
ipt_state
ipt_multiport
iptable_filter
ipt_limit
ipt_LOG
ipt_REJECT
ipt_conntrack
ip_conntrack
ip_conntrack_ftp
iptable_mangle

Other modules for additional functionality:
ipt_owner
ipt_recent
iptable_nat
ipt_REDIRECT

You can check the hosting environment using :

/etc/csf/csftest.pl

This
should run without any FATAL errors. If any such errors are present,
check the module failed and see if it is installed on node. You can use
“lsmod” command for that.
Eg :
Code: 

# lsmod | grep ipt_limit

If any of the modules is not present on the node, install it using modprobe command.
Eg :

# modprobe ipt_limit

Then to enable modules in VPS :

# vzctl set CT_ID --iptables ip_tbales ipt_multiport --iptables ipt_REJECT 
--iptables ipt_recent --iptables xt_connlimit --iptables ipt_owner --iptables 
ip_conntrack --iptables iptable_nat --iptables iptable_mangle --iptables 
ipt_state --iptables ipt_limit --iptables ipt_LOG --iptables ipt_owner --save 

(Replace CT_ID with container ID)

These changes will be applied after the container restart.

If
you get any “memory allocation” errors with iptables on a VPS, make
sure that your numiptent setting is set sufficiently high.  Set
numiptent  to at least 1000.

# vzctl set CT_ID --numiptent 1000 --save

(Replace CT_ID with container ID).

can not open `/var/lib/mlocate/mlocate.db’: No such file or directory

It
is a common issue while using locate command, and the error is because
we haven’t created the db for locate. To create db for locate, simply
run the command :

# updatedb

Wait for it to complete and run the locate command again. It should be working fine this time…!!! 
You can use the same command (updatedb)to update recent changes to locate’s db.

To check :
Open
SQL Management Studio, click on the “New Query” button. In the query
window paste the following and click the “Execute” button :

SELECT * FROM sys.configurations
WHERE name = 'clr enabled'

To enable CLR integration, use the clr enabled option of the sp_configure stored procedure:

Execute the below query :

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'clr enabled', 1;
GO
RECONFIGURE;
GO

Then click the “Execute” button to run the stored procedure.

In the SQL Server “Messages” window you should see messages similar to below ones :

Configuration option ‘show advanced options’ changed from 0 to 1. Run the RECONFIGURE statement to install.
Configuration option ‘clr enabled’ changed from 0 to 1. Run the RECONFIGURE statement to install.

That’s all..!!

1) Log into WHM as root and click on “Email” section.
2) Select “Repair Mailbox permissions“
3) It will show a message like :

This function will inspect mailbox ownership and permissions and attempt to 
fix any issues that may exist. 

Click “Proceed >>” button.

The error normally occurs when PHP tries to process a big database
records or when importing or exporting. To solve the error, there are
two fixes. One is to increase PHP memory limit of the account by using a
custom php.ini file. But sometimes it won’t work.

If it didn’t
work, then you can fix the error by increasing the memory of the
particular PHP script (displayed in error message) by adding an
additional line at the top of the script:

ini_set(”memory_limit”,”32M”);  

  (Change the value based on the error message).

Now
browse the page again, perform the operation again. It will just work
fine if you have set correct value based on the error message.
