OK I figured this will be a simple task. It is. There are a few things that you need to be cautious about if you are using Remi as php base. The modules will not be loaded magically.

Three steps:
1. Copy or link the module to your system library, you need to do the same for 3 files for PHP 5.x: igbinary.so, memcached.so and msgpack.so

for i in igbinary.so memcached.so msgpack.so
do
  ln -s /opt/remi/php56/root/usr/lib64/php/modules/$i /usr/lib64/php/modules/$i
done

For PHP 7 you do not need the igbinary file.

2. Add the following modules to /etc/php.d directory using ordering, each of the file contains only a line of extension = xxx.so
20-msgpack.ini

extension = msgpack.so

20-igbinary.ini

extension = igbinary.so

30-memcached.ini

extension = memcached.so

3. Restart php-fpm
Depend on your configuration, you might not be using php-fpm. Restart it so that the changes can apply to your website.

When you go to Tools -> Memcached in WordPress, you shall see this line:
Using the PHP Memcached class to interact with Memcached

It proves that you are using Memcached!

Nginx is more and more widely used in recent years, so the filter rules will be based on nginx settings.

I didn’t use all of those, some might be genuine browser user agent, like Maxthon

The following rules are to block WordPress specific locations and files. For other web programmes you can change the directories to whatever suits you.

# Rules to block access to WordPress specific files and wp-includes
location ~ /\.ht { deny all; }
location ~ wp-config.php { deny all; }
location ~ readme.html { deny all; }
location ~ readme.txt { deny all; }
location ~ /install.php { deny all; }
location ^wp-includes/(.*).php { deny all; }
location ^/wp-admin/includes(.*)$ { deny all; }

Block execution of use-uploaded .php files.

# Rules to prevent php execution in uploads
location ^(.*)/uploads/(.*).php(.?){ deny all; }

Block suspicious URLs:

set $susquery 0;

Rules to help reduce spam

Changing header width:
This is done in section 3.0

...
.site {
    ...
    max-width: 100%;
}

This is done in section 4.0

...
.site-header {
    ...
    max-width: 100%;   // rather than 1260px
    ...
}

You can also change the content width [optional], you don’t have to change this. It’s my personal adjustment

This is done in section 6.0

...
.page-content {
    ...
    max-width: 600px; // rather than 474px
    ...
}

I didn’t test with 1366×768, not sure how it would look like. And sorry for the 800×600 users.

PS: 1366×768 is evil!
That’s all.

yum install nodejs

will take care of the rest.

For ghost, MarkDown language is a must to learn, and its initial blog article has nearly everything you need.

Pros:

1. ghost is built on NodeJS, and this is blazing fast. The designers of ghost clearly have a neat idea of how publishing works. In comparison, WordPress is too heavy, it has too many functions that I basically won’t use at all, and it is also heavily based on PHP, which is a large CPU resource consumer. For a blog that has 5000 PV per day (not mine absolutely!), VPS in general simply can’t handle them all, so the cost could be lower if you use ghost

2. Looks great! In my opinion, personaly blogging should be as neat and clean as what ghost is like.

3. Sqlite database. Well for this, different people would have different opinions. For a personal blog, SQLite is enough though.

4. Mobile device friendly. I know WordPress has put a lot efforts on mobile devices, but, on my old iPhone 3GS, WP cannot match with ghost on mobile display and publishing, ghost is much much nicer.

Cons:

1. Plugins availability = none. WP beat up ghost completely in this area. Because of ghost‘s early birth, the programmers behind it haven’t got the time to develop APIs for plugins, so my plugin, it will not work on ghost as well as other plugins like syntax highlighting etc.

2. Where is “Search” in ghost? It could be that I am blind or the function hasn’t been developed at all.

Anyway, ghost is at its early stage, it is not suitable yet to convert from WP to ghost, but we’ll see how it’ll go.
