What is eAccelerator?

[Saku]

doesn't work too

[root@serverge11 eaccelerator-0.9.3]# ./configure --with-eaccelerator=shared --with-php-config=/usr/bin/php-config
-bash: ./configure: No such file or directory
[root@serverge11 eaccelerator-0.9.3]# ./configure --enable-eaccelerator=/root/eaccelerator-0.9.3 --with-php-config=/usr/bin/php-config
-bash: ./configure: No such file or directory
[root@serverge11 eaccelerator-0.9.3]#

[Saku]

please help me to finish eaccelerator's installation, my site still overloading my server's CPU

[bluemuse]

can someone help me. I've tryed to install php-devel to have acess to phpize.

Php-devel was sucessfully installed:

warning: php-devel-4.3.4-11.i386.rpm: V3 DSA signature: NOKEY, key ID 4f2a6fd2
Preparing...                ########################################### [100%]
   1:php-devel              ########################################### [100%]

But then when I try to access phpize, it seems it is not there. How do I certify that?

# /usr/bin/phpize
/usr/bin/phpize: line 57: aclocal: command not found

I think autoconf isn't installed on your server. Try:
yum install autoconf

[bluemuse]

i think it is:

locate autoconf
/var/cache/yum/base/headers/autoconf213-0-2.13-8.noarch.hdr
/var/cache/yum/base/headers/autoconf-0-2.59-3.noarch.hdr
/usr/include/linux/autoconf.h
/lib/modules/2.6.10-1.771_FC2/build/include/linux/autoconf.h
/lib/modules/2.6.5-1.358/build/include/linux/autoconf.h


what do u suggest?

[Compuart]

those are merely source files. Try running autoconf:
autoconf --version

If it doesn't find it, it'd need to be installed.

[bluemuse]

it might be the problem.
I installed autoconf:

yum install autoconf

[bluemuse]

it worked out this time

but another problem right in the end of the process:

make
make: *** No targets specified and no makefile found.  Stop.
[root@xxx eaccelerator-0.9.3]# su
[root@xxx eaccelerator-0.9.3]# mkdir /tmp/eaccelerator
[root@xxx eaccelerator-0.9.3]# chown apache:apache-group /tmp/eaccelerator
chown: `apache:apache-group': invalid group
[root@xxx eaccelerator-0.9.3]# chmod 1700 /tmp/eaccelerator
[root@xxx eaccelerator-0.9.3]# make install
make: *** No rule to make target `install'.  Stop.

[ozmafans]

The install guide says to change anything in italic to what your server has it set to. It clearly says that apache-group is not a valid group, that you need to change that to the group your apache runs under. "nobody is usually the group this is run as"

so the command would be:

chown apache:nobody /tmp/eaccelerator

which is why it says invalid group.

And, since your initial command of make failed, make install will also fail. Make builds it, make install puts it all together. Then you likely need to

cp modules/eaccelerator.so /usr/lib/eaccelerator.so

[bluemuse]

and this error:

make
make: *** No targets specified and no makefile found.  Stop.


is it normal?

[ozmafans]

No. did your ./configure command run properly?

to "try again" do the following:

inside the eaccelerator directory:

$ make clean
$ ./configure --enable-eaccelerator=shared --with-php-config=/usr/bin/php-config
$ make
$ su
# mkdir /tmp/eaccelerator
# chown apache:nobody /tmp/eaccelerator
# chmod 1700 /tmp/eaccelerator
# make install
# cp modules/eaccelerator.so /usr/lib/eaccelerator.so

report back if you have problems...

[bluemuse]

./configure run properly.

but the make command always give me that error message.

and also that make clean gives me this

make clean
make: *** No rule to make target `clean'.  Stop.

[Webrunner]

should i install this on PHP5 with mysql 4.1 and apache 2?

[Compuart]

./configure run properly.

Are you sure it doesn't show any errors?

should i install this on PHP5 with mysql 4.1 and apache 2?

Yep, this or APC of course, whichever you like best.

[bluemuse]

this is what i get:

that did not go well Try installing gcc:

It might need C++

Try:
yum install gcc-c++

[Webrunner]

I am not that great with Linux and i read that eAccelerator isn't compatible with php5.
I used apt-get to install php5 on Sarge (Debian).
Can i just install eAccellerator from the source code?

[Compuart]

According to themselves they have fixed that in 0.9.4 RC2 ("eA should be php 5 compatible except some very unusual cases."). You can always try to compile eaccelerator. If it works, it'll compile a module you then can include in the php.ini file. If it fails after that, simply remove it from php.ini and it's gone. So not much risk involved.
