Personal Mind of ASEP

For Dedicated Server or VPS users, Apache, PHP and MySQL Optimization is very important, because with a little optimization will reduce the burden on our resources of dedicated or VPS put through the process, especially if our server has a limited hardware resources.

Here I will attach some optimizations for Apache web server is one that is fast, reliable and flexible. But it is by default, Apache can take a lot of resources. In it I also convey to the optimization of PHP and MySQL so our servers will be faster and save server resources used.

Turn off Apache and MySQL service:

PHP Optimization

Remove remark or comment in the file /usr/local/etc/php.ini, so that the contents of a file like the following:

Prepare the PHP error log file:

Apache Optimization

Remove modules that are not needed and the remark or comment in the file /usr/local/etc/apache22/httpd.conf. Thus becomes:

Edit MPM worker file ini /usr/local/etc/apache22/extra/httpd-mpm.conf :

Edit Virtual Host at file /usr/local/etc/apache22/extra/httpd-vhost.conf :

Edit the default configuration file /usr/local/etc/apache22/extra/httpd-default.conf :

Enable mod_deflate by creating a file /usr/local/etc/apache22/Includes/mod_deflate.conf contains:

Check the Apache configuration:

MySQL Optimazitaion

The contents of the file /var/db/mysql/my.cnf:

Run all the services by typing:

Hopefully the discussion Apache, php and mysql optimization can be a reference for all of us in the optimization of our server

Litespeed Web server is a new technology that was created to replace the Apache Web Server in the future. Litespeed according to research results has the advantage that is 50% faster in processing the PHP and 6x faster than the Apache Web Server.

Some of the advantages Litespeed Web server:

1. Restrictions HTTP request validation
2. Anti-DDoS
3. Prevention System Overloading
4. Recover from failure to directly and automatically
5. Compatible with Cpanel, Plesk and Direct Admin
6. Support compatibility with mod_security filtering request
7. Compatible with Apache .htaccess
8. Restart without any Down Time
9. Migration from other web servers is very fast and easy

We have had many shared hosting providers, VPS and dedicated servers that have implemented licensing LiteSpeed ​​for their service

Suitable for servers that require extra performance.

Instead of renting a large server specification, consider using litespeed web server.

Let us all know about the differences of the virtualization technology that uses OpenVZ (Virtuozzo) and Xen VPS, including the advantages and disadvantages of both because the existence of virtualization technology allows us to get access like a dedicated server.

Virtualization technology that is currently the most popular of OpenVZ and XEN. Both have advantages and disadvantages. These are things you need to understand before deciding to take which.

Let’s discuss the differences in both:

OpenVZ (called Virtual Private Server / VPS)

Pros:

1. Can overselling
2. Setup is easier to remember linux partition that is used by default
3. Using the Burst RAM
4. Server management is easier than Xen
5. Using less resources

Disadvantages:

1. Does not support SWAP
2. All VPS are highly dependent on node (because the kernel go to the node).
3. If you run out of memory dedicated and Burst (fixed), the VPS will be down.
4. Some settings are limited by the Node
5. Only supports linux

XEN (called Virtual Dedicated Server / VDS)

Pros:

1. The system stands alone as a Dedicated Server
2. Using SWAP
3. Almost no problem with setting because it is not limited by the node
4. If Memory Dedicated expires, the SWAP will function automatically and do not like OpenVZ is down, the XEN only causes the system will slow VDSnya
5. Can support the installation of Windows Server

Disadvantages:

1. Node setup with LVM partition (Because it requires a VG to client VDS)
2. XEN can only run stable at least 256 MB of RAM memory
3. Need more space in the node to temp process
4. Can not do overselling
5. Require large resources

Xen is usually the first choice for sites that require more memory. Especially for users who plan to do many tasks that require additional memory, such as video encoding, compilation or the development of Java applications.

Most Xen has to offer is Xen PV (paravirtualization). Xen PV support only linux.

Use the disk as swap memory. If the swap is already in use, then the disk io will go up and the server will be overloaded by the weight of the disc.

XEN price is also far more expensive than OpenVZ due to its inability to overselling.

Noteworthy for its OpenVZ is Guaranteed RAM. If burstable RAM shared his reply was, in the sense that sellers can provide burstable ram with a total physical RAM above who has.

OpenVZ is much faster than XEN on condition not to overselling, especially when it burst its 3-4 times above the guarantee of RAM.

Therefore, the OpenVZ seems to be a better option for many people. Not only is it faster for daily operations, but also more consistent and less overload.

Based on personal experience, XEN is consuming more memory than OpenVZ.

For those of you who are beginners in using the VPS, you should take OpenVZ.

Thus our discussion about the difference OpenVZ (Virtuozzo) and Xen VPS, hopefully with this discussion, you who are interested to buy a VPS service can get insight before making a reservation VPS

Virtual Private Server (VPS) is a software technology that enables the sharing of resources into multiple virtual machines (servers). Each virtual server will have the system running independently. VPS provides full access to the root user, each VPS has a configuration that can be arranged like the physical server (dedicated server).

VPS Advantages

• Save costs
  If we use a dedicated server of course will require a fairly expensive cost, while our needs quite simple example, only requires a web server, mail server, or for data backup only. This can be done with the VPS in saving costs for datacenter infrastructure.
• Good Performance
  VPS has a good performance when compared with the shared-hosting, where the shared-hosting sometimes less stable when the load gets high enough (in general have a shared-hosting account that many). For those of you who have a website with traffic and the process is quite high, suitable for your VPS. VPS performance will not be disturbed by any other VPS users.
• Flexible
  You have the freedom to choose the operating system and software you want to use.
• Maintenance is simple
  Physical server in-maintenance by VPS hosting providers, so we just manage the virtual server is all we have.

VPS Disadvantages

• All server hardware is used by users of the VPS, this includes the use of CPU, RAM and hard drive.
• Must have a special ability in managing the administration server.

This time i want to talk how to Install WordPress on Ubuntu Server using Nginx, PHP, MySQL. If during the time we are familiar with Apache web server, now in writing this time I do not use Apache as web server, but using Nginx.

Please read and read Apache vs Nginx: Web Server Performance Deathmatch to know a little performance comparison between Apache and Nginx.

Immediately, we practice, let’s …

Install the necessary software (nginx, php, mysql, compiler, and additional software)

1. Nginx Configuration

Edit nginx configuration in order to be run as we expected.

Then uncomment the sections below:

Spawn-fcgi configuration

We can use the spawn-fcgi lighttpd, so it means you have to build from source to get its binary.

Create a script to run spawn-fcgi

Give 755 permissions for the script can be executed.

Running init-FastCGI and settings for this script is executed when the server machine on reboot.

Start the service nginx

Test setup nginx + php + mysql configuration using phpinfo.

2. MySQL Configuration

Make sure the MySQL server service is running well.

3. Instalasi WordPress

Edit customize wordpress configuration settings database which we have set previously.

Once saved, navigate your browser to http://server_nginx/wordpress/wp-admin/install.php, if we are doing right setting, it will show the wizard for the installation of wordpress, please follow the wizard to finish and tutorial how to Install WordPress on Ubuntu Server using Nginx, PHP, MySQL is finish too :d
