How to Install Nginx with PHP5 and MySQL on CentOS 5.5

October 2, 2010 lpilinuxblog Linux How to

Nginx (pronounced “engine x”) is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on a CentOS 5.5 server with PHP5 support (through FastCGI) and MySQL support.

I do not issue any guarantee that this will work for you!

1 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.

2 Installing MySQL 5

First we install MySQL 5 like this:

yum install mysql mysql-server

Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:

chkconfig –levels 235 mysqld on
/etc/init.d/mysqld start

Now check that networking is enabled. Run

netstat -tap | grep mysql

It should show something like this:

[root@server1 ~]# netstat -tap | grep mysql
tcp 0 0 *:mysql *:* LISTEN 2388/mysqld
[root@server1 ~]#

If it does not, edit /etc/my.cnf and comment out the option skip-networking:

vi /etc/my.cnf

[...]
#skip-networking
[...]

and restart your MySQL server:

/etc/init.d/mysqld restart

Run

mysql_secure_installation

to set a password for the user root (otherwise anybody can access your MySQL database!):

[root@server1 ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we’ll need the current
password for the root user. If you’ve just installed MySQL, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): < -- ENTER
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] <-- ENTER
New password: <-- yourrootsqlpassword
Re-enter new password: <-- yourrootsqlpassword
Password updated successfully!
Reloading privilege tables..
... Success!

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] <-- ENTER
... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] <-- ENTER
... Success!

By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] <-- ENTER
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] <-- ENTER
... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MySQL
installation should now be secure.

How to Upload Files to an FTP site via a Batch Script

October 2, 2010 lpilinuxblog Linux Tricks

This script can be used from the command line as a ‘no questions asked’ method of uploading one or many files with a single command. Additionally, you can call this script from batch files to perform automated file uploads. A few uses for this include (but, of course, not limited to):

* Include in backup scripts to send data offsite.
* Upload html/php/etc. files to a web server with a single command.
* Create shortcuts to send a common group of files (such as a web site’s source pages).

Configuration

The only configuration required is to set the FTP server connection information. Under the “Connection information” line, set the following:

* Server – The FTP Server you are uploading to. You can either enter the DNS name (ftp.myserver.com) or IP address (1.2.3.4).
* UserName – Your user name for connecting to FTP server.
* Password – Your password for connecting to the FTP server.

Depending on your firewall settings, the first time you run this script you may be prompted to allow FTP to connect to the Internet. Setting this to never prompt you again should remove future warnings.
The Script
