There is a lot of information on the Internet for the installation steps of PHP, which is very detailed. However, since the installation of free software such as Apache and PHP does not have a user-friendly interface like commercial software, many netizens rarely encounter this kind of stuff, so even though there is an installation information next to it, they still encounter many problems. question. I have also noticed that many netizens always ask similar questions on many domestic forums about Linux and PHP. Therefore, I write down the solutions to this type of problem that I know. Please point out any mistakes.
1. The installation of free software, whether in Win32 or Linux, generally has a README. Before installation, read it carefully and you will gain a lot.
2. Install Apache
This step should be relatively simple. As long as you remember to set the BindAddress, ServerName, and DocumentRoot in httpd.conf, you should be able to see the familiar Apache icon. BindAddress refers to the IP address that can answer calls, which can be *, IP address, or a complete domain name. ServerName is the host name. If there is no domain name, you can use IP. DocumentRoot is the default home page location. Remember to restart Apache after modifying httpd.conf.
3. Install PHP
This step has many problems. In the final analysis, there are two reasons. One is that PHP does not work. This is because there is a problem with the settings of the PHP part in httpd.conf; the other problem is PHP startup. But there is an error when running the PHP file. This is because php.ini is not set properly.
1. httpd.conf settings
Under win32, these lines are indispensable
ScriptAlias /php "d:/php/php.exe"
Action application/x-httpd- php "/php"
AddType application/x-httpd-php .php .php3
The first two lines indicate the location of the PHP script interpreter, and the third line indicates the file suffix to be interpreted by the PHP script.
If it is not PHP4 but PHP3, change "application/x-httpd-php" to "...httpd-php3", remember.
If the first two lines are not set properly, the PHP file will be downloaded or displayed on the page.
In Linux, if PHP runs as an Apache module, then just add the third line, but you should pay attention to the steps when installing. You must install PHP first, and then add it when configuring Apache. --activate-module={path to libphp4.a}, then make, make install...
