How to Display Logical volumes in slave node LVM manager

Now we will see the steps that our Support Techs follow to fix this error.

Cause

The Slave node is running OS vendor PHP version.

Steps to follow:

a) We must switch to svmstack PHP version first.

This can be done with a script using the following steps:

1. First, we need to connect to the SolusVM Master/slave server over SSH.

2. Then download and execute the script to switch to the latest stack:

# curl -o svmupgradestack.sh https://raw.githubusercontent.com/solusvm-support/helpers/master/svmupgradestack.sh && sh svmupgradestack.shCopy Code

3. In the prompt we can either select Master or Slave depending upon the type of node.

For switching to svmstack PHP version manually we can use the below steps:

1. First run the following command:

# yum update svmstack-php && mv /usr/bin/php /usr/bin/backup-phpCopy Code

2. Then to Create a link to SolusVM PHP binary we can use the following:

# ln -s /usr/local/svmstack/php/bin/php /usr/bin/phpCopy Code

b) After that we can Install the SolusVM repository using the following command:

# yum install solusvm-releaseCopy Code

c) Now we will stop and disable the Lighttpd web server using the following command:

# service lighttpd stop
# chkconfig lighttpd offCopy Code

d) Install Nginx web server and legacy configuration:

For Master server:

# yum install svmstack-nginx svmstack-nginx-legacy-master-configCopy Code

For Slave server:

# yum install svmstack-nginx svmstack-nginx-legacy-slave-configCopy Code

e) After this we can enable svmstack-* services using the following:

# chkconfig svmstack-nginx on
# chkconfig svmstack-fpm onCopy Code

f) Finally, we can start services using the following:

# service svmstack-nginx restart
# service svmstack-fpm restartCopy Code
