We’ll show you, how to speed up VestaCP on CentOS 7. Vesta Control Panel is a simple and easy to use open source hosting control panel. It has a simple and clean interface and lots of useful features that will help you to host your websites on your VPS. Vesta Control Panel currently can be installed on RHEL 5, RHEL 6, CentOS 5, CentOS 6, CentOS 7, Debian 7, Debian 8, Ubuntu 12.04, Ubuntu 12.10, Ubuntu 13.04, Ubuntu 13.10, Ubuntu 14.04 and Ubuntu 16.04 operating systems. Today we are going to learn how to speed up VestaCP on a CentOS 7 VPS.
1. Upgrade PHP
First make sure the system is up to date:
# yum update
Now let’s enable the remi-php70 repository so we can upgrade VestaCP to PHP 7:
# yum-config-manager --enable remi-php70
Update the system again, this command should upgrade all PHP packages to PHP 7:
# yum update
And then restart the php-fpm service:
# systemctl restart php-fpm
2. Install Opcache
Installing Opcache is pretty easy, just run the following command:
# yum install php-opcache
Restart the php-fpm service again:
# systemctl restart php-fpm
Restart Nginx as well:
# systemctl restart nginx
Now you should check if Opcache is enabled by running the following command:
php -i | grep opcache.enable
If Opcache is enabled you should see something like the following output:
opcache.enable => On => On
3. Upgrade MariaDB
First make a backup from all of your databases.
Instead of the conventional mysqldump utility you can use the VestaCP CLI to generate a backup for all of the users on your system, if you want to do that just run:
# v-backup-users
In case you need to restore the backup, first obtain the backup file name by typing in:
# v-list-user-backups <username>
And then by executing the following command you can restore all databases for a specific user:
# v-restore-user <username> <backup_name> no no no <username> no no no
Note: Replace <username> for the username you want to restore the databases for and <backup_name> for the name of the backup obtained by the v-list-user-backups command.
Now, let’s get to upgrading MariaDB finally, start by removing the old MariaDB version:
# yum remove mariadb mariadb-server
Add the repository for MariaDB 10 by creating the repo file with nano and then paste the text below:
# nano /etc/yum.repos.d/MariaDB.repo # Used to install MariaDB 10 instead of default 5.5 # http://mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = https://yum.mariadb.org/10.2/centos7-amd64/ gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
Now update the system again:
# yum update
And then install MariaDB 10:
# yum install mariadb mariadb-server
After the installation has finished, start MariaDB by running the following command:
# systemctl start mariadb
Then enable the MariaDB service on boot:
# systemctl enable mariadb.service
4. Install Redis
Redis is an in-memory data structure store primarily used as a database and cache.
You can get a huge speed benefit from configuring Redis to cache your pages or to cache your database rows.
You can install Redis by typing in the following command:
# yum install redis
After the yum package manager has finished installing Redis, type in the following command to start Redis:
# systemctl start redis
Now enable the Redis service to start on boot:
# systemctl enable redis.service
5. Configuring WordPress
If you use WordPress for your sites then it would be quite beneficial to install Redis as a caching system for WordPress.
We are going to need the Phpredis extension in order to configure WordPress to use Redis, first install this package:
# yum install php-devel
Then install the Phpredis extension using this command:
# pecl install redis
Press enter when the following message comes up:
enable igbinary serializer support? [no]
After PECL has finished installing Phpredis, open the php.ini file and add the following line at the bottom:
# nano /etc/php.ini extension=redis.so
Restart php-fpm in order to make the changes effective:
# systemctl restart php-fpm
Now log in to your WordPress backend and install the plugin W3 Total Cache and activate it.In the plugin settings for W3 Total Cache select Redis as page cache and database cache then check the Enable checkbox for both options and click on the Save all settings button.When finished restart Nginx:
# systemctl restart nginx
Then turn on the Redis monitor by typing in the following command:
redis-cli monitor
Now using your browser navigate to your WordPress page, if Redis is working you should see output similar to this:
