Hi,

I want change the memory limit in the php.ini file for around 100 servers and I have got couple of questions.

1. What is the command will find the parameter memory_limit=XX and change it to memory_limit=128M ?

2. I want to make this change on around 100 remote servers for which I have root password. Any ideas how to do it through a script?

for the 2nd question you can read through this thread. I was looking for a similar solution to a problem

You'll need to set up SSH keys.

mmm..........i looked into the links, but I don't have scripting knowledge at all so I can't make it myself. Anyways, please answer the 1st question and then we will discuss the 2nd.

Thanks for the reply

Test this for starters:
sed -i 's/memory_limit=.[0-9]M/memory_limit=128M/g' /path/to/php.ini

Would have been easier if you only have "memory_limit=nnnM" and no other characters/numbers after it on that line.

Code:

sed -i.bak -r 's/(memory_limit[ \t]*=[ \t]*)[^\t ;]+(.*)/\1128M\2/' php.ini

Once the authentication to those machines is enabled (will be a tad
tedious) you can do something like:

Code:

for i in `cat hostlist`; do ssh user@${i} "sed -i.bak -r 's/(memory_limit[ \t]*=[ \t]*)[^\t ;]+(.*)/\1128M\2/' /etc/apache/php.ini"; done

Cheers,
