Introduction

Apache is a first class web server. This file outlines some maintenance operations for local Mac usage and Ubuntu.

Configuration file

$ cd /etc/apache2
$ nano apache2.conf
$ nano httpd.conf

# Include generic snippets of statements
Include conf.d/

# Include the virtual host configurations:
Include sites-enabled/

If problems arise try remove sites from the config to eliminate bugs in scripts

MPM configuration

List compiled in modules

$ apache2 -l

Check for the prefork.c module to know what section of the configuration to modify

Server maintenance

Change user to root sudo -s

$ sudo service apache2 restart

scp ~/.ssh/rackspace/id_rsa.pub [email protected]

http://cbracco.me/ssh-keys/ ssh-add -K ~/.ssh/rackspace/id_rsa

Log files

Log files by standard are stored in this

$ cd /var/log/apache2

View the last 100 entries of a log file

$ tail -100 /var/log/apache2/access.log
$ tail -100 /var/log/apache2/error.log

Log file removal

$ df -h
$ du -hs
$ du -a /var | sort -n -r | head -n 100

$ cd "/var/www/storage/logs"
$ sudo rm -vi /var/www/storage/logs/*

$ rm -vi /var/log/apache2/*ls -al

$ find . -name "*.gz" -type f
$ find . -name "*.gz" -type f -delete
