Changing eaccelerator cache directory

Issue :

We know that the default directory for eaccelerator cache is “/tmp/eaccelerator”. In most of the cases, this directory causing the /tmp to fill and that will cause many issues. In such cases it’s better to change the cache directory to another large partition.

Solution:

Use the following command to find cache director specified in “php.ini”‘ file.

# grep eaccelerator.cache_dir /usr/local/lib/php.ini

i.e;

root@tricks[~]# grep eaccelerator.cache_dir /usr/local/lib/php.ini
eaccelerator.cache_dir=”/tmp/eaccelerator”
root@tricks[~]#

Then change it to another directory “/var/eaccelerator” and save the file.

i.e; eaccelerator.cache_dir=”/var/eaccelerator”

Then create the folder “/var/eaccelerator”

# mkdir /var/eaccelerator

After that use the following commands.

#service httpd stop

#rm -rf /tmp/eaccelerator

#service httpd start

That’s all….!!!!

sh: /usr/local/bin/sendmail-logger: No such file or directory

Issue: I got the above error while trying to send mail from a test php file after enabling mail() function on the server.

sh: /usr/local/bin/sendmail-logger: No such file or directory

Solution:

1.copy /usr/local/lib/php.ini to the user’s document root and change the ownership.

# cp  /usr/local/lib/php.ini /home/username/public_html

#chown username.username /home/username/public_html/php.ini

2.Then edit /home/username/public_html/php.ini

# vi /home/username/public_html/php.ini

Now change the php.ini as described below.

sendmail_path = “/usr/sbin/sendmail -t -i” –> enable this
;sendmail_path = /usr/local/bin/sendmail-logger—> comment this

That’s all………!!!
