Install Lamp server from iso distrib Ubuntu 12.04<\/h2>\n

By default the address of your local webserver is localhost or 127.0.0.1 if you want to use an IP, you can type it as the address and reach your document root. If you have created a dir under the DR called test (as in \/var\/www\/test\/), navigate to the content of this folder simply by going to http:\/\/localhost\/test\/ or http:\/\/127.0.0.1\/test\/ in your web browser. In a nutshell every web address is relative to the DR.
\nType the following command :<\/p>\n

# sudo tasksel install lamp-server\r\n\r\n<\/pre>\n\n
Apache2 Performance parameters<\/h2>\n
Open file http.conf file as shown under \/etc\/apache2\/ below<\/p>\n
\"apache1\"<\/a><\/p>\n
\"apache2\"<\/a><\/p>\n
<\/pre>\n
\n
Apache2 Permissions<\/h2>\n
www-data is a user\/group set created specifically for web servers. It should be listed in \/etc\/passwd as a user, and can be configured to run as another user in \/etc\/apache2\/apache2.conf.
\nBasically, it\u2019s just a user with stripped permissions so if someone managed to find a security hole in one of your web applications they wouldn\u2019t be able to do much. Without a lower-user like www-data set, apache2 would run as root, which would be a Bad Thing\u00ae since it would be able to do anything and everything to your system.<\/p>\n
www-data or daemon :<\/strong>
\nWhat version of ubuntu are you using?
\nhttpd.conf shouldn\u2019t be in use. It should be \/etc\/apache2\/envvars<\/p>\n
Code:\r\n# envvars - default environment variables for apache2ctl\r\n\r\n# Since there is no sane way to get the parsed apache2 config in scripts, some\r\n# settings are defined via environment variables and then used in apache2ctl,\r\n# \/etc\/init.d\/apache2, \/etc\/logrotate.d\/apache2, etc.\r\nexport APACHE_RUN_USER=www-data\r\nexport APACHE_RUN_GROUP=www-data\r\nexport APACHE_PID_FILE=\/var\/run\/apache2.pid<\/pre>\n
And yes, www-data is system user, created by apache.
\nHow are you checking users? are you just issuing \u2018users\u2019 from the command line?
\nIf you are you will only see real users there, not www-data because apache is a daemon running under the user www-data<\/strong>
\nyou can<\/p>\n
 #cat \/etc\/shadow<\/pre>\n
and that is a grimmy way if listing all valid users.<\/p>\n
\n
Apache2 \/var\/www\/site1 Permissions<\/h2>\n
Method 1<\/strong><\/p>\n
sudo chown -R yourname:www-data site1<\/pre>\n
then<\/p>\n
sudo chmod -R g+s site1<\/pre>\n
First command changes owner and group Second command adds s attribute which will keep new files and directories within site1<\/strong> having the same group permissions<\/p>\n
\n
Method 2<\/strong>
\nIf you are the only developer, why not just make the owner of \/var\/www\/ you?<\/p>\n
$ sudo chown -R mike \/var\/www\/<\/pre>\n
and set permissions to 755 for directories and 644 for files.
\nAfter this you would want to do this to set the right permissions for your files and directories.
\nto change all the directories to 755:<\/p>\n
find \/var\/www -type d -exec chmod 755 {} \\;<\/pre>\n
to change all the files to 644:<\/p>\n
find \/var\/www -type f -exec chmod 644 {} \\;<\/pre>\n
\n
Method 3<\/strong><\/p>\n
you@yourbox:~$ sudo -i\r\n[sudo] password for you: [password]\r\nroot@yourbox:~# cd \/var\/www\r\nroot@yourbox: \/var\/www# mkdir site1\r\nroot@yourbox: \/var\/www# chown you:www-data site1\r\nroot@yourbox: \/var\/www# chmod 0750 site1\r\nroot@yourbox: \/var\/www# logout\r\nyou@yourbox:~$ ln -s \/var\/www\/site1 \/home\/you\/site1\r\nyou@yourbox:~$ exit<\/pre>\n
