Compile PHP into Apache static kernel on Linux

Article title: compile PHP into Apache static kernel on Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Note: There are two ways to integrate Apache into PHP: one is the DSO mode, which calls PHP as an external module of Apache, which increases the flexibility of Apache, however, it will reduce the performance by 5%. Another way is to compile PHP into the Apache kernel, which sacrifices the flexibility of future adjustments (every time PHP is re-compiled, but the performance will be higher. This is also true for Perl. In contrast, I prefer to use the second method, that is, to compile PHP into the static kernel of Apache.

1. compile Apache:

1. go to Apache to expand the directory;

2../configure--prefix =/usr/local/apache1.3--disable-module = all \

--Enable-module = access--enable-module = log_config \

--Enable-module = dir--enable-module = mime \ # Basic module of Apache

(Note: If DSO is used later,--enable-mdule = so will be added during compilation)

2. install PHP:

1. go to PHP to expand the directory;

2../configure--prefix =/usr/local/php4 \

--With-apache = ../apache_1.3.27 # specify the Apache source code directory.

3. make; make install

3. install Apache:

1. go to Apache to expand the directory;

2../configure--prefix =/usr/local/apache1.3--disable-module = all \

--Enable-module = access--enable-module = log_config \

--Enable-module = dir--enable-module = mime \

--Activate-module = src/modules/php4/libphp4.a # compile the PHP module

3. make; make install

4. Configure Apache:

Modify httpd. conf:

1. Timeout 300 ---> Timeout 120

2. MaxKeepAliveRequests 100

3. KeepAliveTimeout 5

4. ServerSignature on ---> ServerSignature off

5. the Options Indexes FollowSymLinks line deletes indexes (the Options in the directory do not include the index option)

6. change the user and group running Apache to nobody.

7. MaxClients 150 --> MaxClients 1500

(This parameter has a basic algorithm, such as a 2 GB machine. an Apache + PHP process consumes about 4 MB of memory, the maximum number of processes is 2g/4 m * 2 = 1000, and the maximum number of processes is 1000*1.5 = 1500; 1.3 to be adjusted to higher than 256, you must modify the source code before compiling Apache)

(For apache2.0, set MaxClients 150 --> MaxClients 1500 in the worker MPM field)

8. Add index. php after DirectoryIndex index.html. var.

9. find the section containing a large number of AddType commands and add the following line: AddType application/x-httpd-php. php

Apache version: Apache-2.0.47

PHP version: PHP-4.3.2

A. install Apache:

Go to the Apache installation directory;

./Configure--prefix =/usr/local/apache2--enable-so

Make; make install

B. install PHP:

Go to the PHP installation directory;

./Configure--prefix =/usr/local/php4-

-With-apxs2 =/usr/local/apache2/bin/apxs

Make; make install

C. configure Apache:

Modify httpd. conf and perform the preceding configuration;

In addition, the modification is as follows:

LoadModule php4_module modules/libphp4.so (This item is automatically added after php is installed)

AddType application/x-httpd-php. php (This item is manually added)
