How to install install Eaccelerator?

To install Eaccelerator manually refer following steps one by one carefully.

1. First you need to login into shell as root user

2. Now we’ll make the eaccelerator directory:

root@gunjan[]#cd ~

root@gunjan[~]#mkdir /eaccelerator/

root@gunjan[~]#cd /eaccelerator/

2. Now download the source file

root@gunjan[~]#wget http://heanet.dl.sourceforge.net/sourceforge/eaccelerator/eaccelerator-0.9.4-rc1.tar.bz2

root@gunjan[~]#bzip2 -d eaccelerator-0.9.4-rc1.tar.bz2

root@gunjan[~]#tar xvf eaccelerator-0.9.4-rc1.tar

3. Now install Eaccelerator:

root@gunjan[~]#cd eaccelerator-0.9.4-rc1/

root@gunjan[~]#export PHP_PREFIX=”/usr”

root@gunjan[~]#$PHP_PREFIX/bin/phpize

root@gunjan[~]#./configure –enable-eaccelerator=shared –with-php-config=$PHP_PREFIX/bin/php-config

root@gunjan[~]#make

root@gunjan[~]#make install

4. Now basically eaccelerator installed, now we need to edit the php.ini files to
include Eaccelerator extension.

root@gunjan[~]#php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/lib
Loaded Configuration File => /usr/local/lib/php.ini

root@gunjan[~]#pico /usr/local/lib/php.ini

copy and paste following lines php.ini carefully
———————-
extension=”eaccelerator.so”
eaccelerator.shm_size=”16?
eaccelerator.cache_dir=”/tmp/eaccelerator”
eaccelerator.enable=”1?
eaccelerator.optimizer=”1?
eaccelerator.check_mtime=”1?
eaccelerator.debug=”0?
eaccelerator.filter=””
eaccelerator.shm_max=”0?
eaccelerator.shm_ttl=”0?
eaccelerator.shm_prune_period=”0?
eaccelerator.shm_only=”0?
eaccelerator.compress=”1?
eaccelerator.compress_level=”9?
———————-

For a Zend extension install server (only if you have Zend installed on your server, or
if you’re going to install it)

———————-
zend_extension=”/usr/lib/php4/eaccelerator.so”
eaccelerator.shm_size=”16?
eaccelerator.cache_dir=”/tmp/eaccelerator”
eaccelerator.enable=”1?
eaccelerator.optimizer=”1?
eaccelerator.check_mtime=”1?
eaccelerator.debug=”0?
eaccelerator.filter=””
eaccelerator.shm_max=”0?
eaccelerator.shm_ttl=”0?
eaccelerator.shm_prune_period=”0?
eaccelerator.shm_only=”0?
eaccelerator.compress=”1?
eaccelerator.compress_level=”9?
———————-

5. Now you need to make the cache directory on your server, where the cache files will be
stored for eaccelerator
root@gunjan[]#cd ~

root@gunjan[~]#mkdir /tmp/eaccelerator/

root@gunjan[~]#chmod 0777 /tmp/eaccelerator/

6. Now restart Apache so that Eaccelerator will start working:

service httpd restart

Now check eAccelerator by using following command

root@gunjan[~]#php -v

Secure FTP by changing FTP port.

In recent few months FTP brute force attacks increased on most the cPanel servers. To avoid such attacks, we can simple default FTP account or change FTP port. If you are shared server then client won’t be happy after disabling default FTP which is cPanel login details. There for simply change the FTP port number by using following steps.

Log in to server as root user and open default FTP configuration file.

server@root[~]pico /etc/pure-ftpd.conf

Search for following line and change it

From

#Bind 127.0.0.1,21

To

It means all ip will connect to FTP service on port 121 but make sure that you have opened a port 121 in server firewall and restart the FTP service.
