Improve install documentation a bit
Summary: - Warn users that they'll need to be comfortable with the CLI. - Move XHProf stuff to the developer docs, since few/no normal users need it. Test Plan: Read documentation.

@title Installing XHProf
|
||||
@group developer
|
||||
|
||||
Describes how to install XHProf, a PHP profiling tool.
|
||||
|
||||
Overview
|
||||
========
|
||||
|
||||
You can install XHProf to activate the XHProf tab in DarkConsole and the
|
||||
`--xprofile` flag from the CLI. This will allow you to generate performance
|
||||
profiles of pages and scripts, which can be tremendously valuable in identifying
|
||||
and fixing slow code.
|
||||
|
||||
Installing XHProf
|
||||
=================
|
||||
|
||||
XHProf is a PHP profiling tool. You don't need to install it unless you are
|
||||
developing Phabricator and making performance changes.
|
||||
|
||||
You can install xhprof with:
|
||||
|
||||
$ pecl install xhprof
|
||||
|
||||
If you have a PEAR version prior to 1.9.3, you may run into a `phpize` failure.
|
||||
If so, you can download the source and build it with:
|
||||
|
||||
$ cd extension/
|
||||
$ phpize
|
||||
$ ./configure
|
||||
$ make
|
||||
$ sudo make install
|
||||
|
||||
You may also need to add `extension=xhprof.so` to your php.ini.
|
||||
|
||||
See <https://bugs.php.net/bug.php?id=59747> for more information.
|
||||
|
||||
Using XHProf: Web
|
||||
=================
|
||||
|
||||
To profile a web page, activate DarkConsole and navigate to the XHProf tab.
|
||||
Use the **Profile Page** button to generate a profile.
|
||||
|
||||
Using XHProf: CLI
|
||||
=================
|
||||
|
||||
From the command line, use the `--xprofile <filename>` flag to generate a
|
||||
profile of any script.
|
||||
|
||||

Overview

Phabricator is a LAMP (Linux, Apache, MySQL, PHP) application. To install
|
||||
Phabricator, you will need:
|
||||
|
||||
- a normal computer to install it on (shared hosts and unusual environments
|
||||
are not supported) running some flavor of Linux or a similar OS;
|
||||
- a domain name (like `phabricator.mycompany.com`);
|
||||
- basic sysadmin skills;
|
||||
- Apache, nginx, or another webserver;
|
||||
- PHP, MySQL, and Git.

Level Requirements
|
||||
==================
|
||||
|
||||
To install and administrate Phabricator, you'll need to be comfortable with
|
||||
common system administration skills. For example, you should be familiar with
|
||||
using the command line, installing software on your operating system of choice,
|
||||
working with the filesystem, managing processes, dealing with permissions,
|
||||
editing configuration files, and setting environment variables.
|
||||
|
||||
If you aren't comfortable with these skills, you can still try to perform an
|
||||
install. The install documentation will attempt to guide you through what you
|
||||
need to know. However, if you aren't very familiar or comfortable with using
|
||||
this set of skills to troubleshoot and resolve problems, you may encounter
|
||||
issues which you have substantial difficulty working through.
|
||||
|
||||
We assume users installing and administrating Phabricator are comfortable with
|
||||
common system administration skills and concepts. If you aren't, proceed at
|
||||
your own risk and expect that your skills may be tested.
