  Introduction: Here will show you how to build a LAMP environment under CentOS (all use source compiler installation) for the web server development.

LAMP: Linux + Apache + PHP + Mysql.
System: CentOS 7,64 bits.
CentOS installation

I selected 64 of the Linux CentOS 7 system, the installation process is very simple, not too much narrative, only a little more about my partitioning:

Partition Name Size
/ Boot 200MB
/ Swap 8GB (not more than physical partition can be)
/ 20GB
/ Home space
Apache compiled and installed

I chose this version httpd 2.2, you can refer to the official documentation.

Installation depends:

Installation depends need to use gcc, g ++ compiler:

######## Gcc, g ++

sudo yum install gcc
sudo yum install gcc-c ++
Here are two apache optimization tools:

######## Apr

wget http://labfile.oss.aliyuncs.com/apr-1.5.1.tar.gz
tar -zxvf apr-1.5.1.tar.gz
cd apr-1.5.1 /
./configure --prefix = / opt / apr
sudo make && make install
######## Apr-util

cd Downloads /
wget http://labfile.oss.aliyuncs.com/apr-util-1.5.4.tar.gz
tar -zxvf apr-util-1.5.4.tar.gz
cd apr-util-1.5.4
./configure --prefix = / opt / apr-util --with-apr = / opt / apr
sudo make && make install
Perl library compatible regular expression library:

cd Downloads /
wget http://labfile.oss.aliyuncs.com/pcre-8.36.tar.gz
tar -zxvf pcre-8.36.tar.gz
cd pcre-8.36
./configure --prefix = / opt / pcre
sudo make && make install
Install apache:

cd Downloads /
wget http://labfile.oss.aliyuncs.com/httpd-2.2.29.tar.gz
tar -zxvf httpd-2.2.29.tar.gz
cd httpd-2.2.29
./configure --prefix = / opt / apache --with-apr = / opt / apr --with-apr-util = / opt / apr-util --with-pcre = / opt / pcre
sudo make && make install
sudo sed -i 's / ^ # ServerName. * / ServerName localhost /' /opt/apache/conf/httpd.conf
test:

start up:

sudo / opt / apache / bin / apachectl start
Get server response (the last step has been installed apache server to localhost):

curl -I 127.0.0.1

shut down:

sudo / opt / apache / bin / apachectl stop

Compile and install MySQL

Installation depends:

Note: The version MySQL5.5 after use cmake to compile.

######## If you previously compiled, you just need to remove the compiler generated file CMakeCache.txt

rm -f CMakeCache.txt

sudo yum -y install gcc gcc-c ++ autoconf automake zlib * fiex * libxml * ncurses-devel libmcrypt * libtool-ltdl-devel * cmake cmake-gui libaio-devel bison-devel make
Compile and install (a long time):

cd Downloads /
wget http://labfile.oss.aliyuncs.com/mysql-5.6.24.tar.gz
tar -zxvf mysql-5.6.24.tar.gz
cd mysql-5.6.24
cmake -DCMAKE_INSTALL_PREFIX = / opt / mysql -DMYSQL_DATADIR = / opt / mysql / data -DWITH_INNOBASE_STORAGE_ENGINE = 1
sudo make
sudo make install
Create mysql user:

id mysql> / dev / null 2> & 1 || sudo useradd -r -s / sbin / nologin -M -d / opt / mysql / data mysql
Initialize the data directory:

sudo chown -R mysql: mysql / opt / mysql / data
sudo / opt / mysql / scripts / mysql_install_db --basedir = / opt / mysql --datadir = / opt / mysql / data --user = mysql --defaults-file = / opt / mysql / support-files / my-default .cnf
Modify the configuration file:

sudo sh -c 'cat >> /opt/mysql/my.cnf < < EOF
basedir = / opt / mysql
datadir = / opt / mysql / data
log-error = /opt/mysql/data/error.log
pid-file = /opt/mysql/data/mysql.pid
port = 3306
EOF '
Remove residual files:

sudo sh -c 'for file in /etc/mysql/my.cnf /etc/my.cnf; do [-f $ file] && rm -f $ file; done'
start up:

sudo /opt/mysql/support-files/mysql.server start
Success is displayed:
Write image description here

test:

/ Opt / mysql / bin / mysqladmin ping

View database:

/ Opt / mysql / bin / mysql -u root -e 'show databases;'
shut down:

sudo /opt/mysql/support-files/mysql.server stop

PHP compiler installation

cd Downloads /
sudo yum install zlib1g-dev libbz2-dev libcurl4-gnutls-dev libjpeg-dev libpng12-dev libfreetype6-dev libmcrypt-dev libxml2-dev
sudo yum install bzip2-devel.x86_64 -y
sudo yum -y install curl-devel
sudo yum install openssl.x86_64 openssl-devel.x86_64 -y
sudo yum install libjpeg.x86_64 libpng.x86_64 freetype.x86_64 libjpeg-devel.x86_64 libpng-devel.x86_64 freetype-devel.x86_64 -y
sudo yum install libjpeg libjpeg-devel libpng libpng-devel

######## Installation Libmcrypt
tar -zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8
./configure
sudo make
sudo make install Description: libmcript installed by default in / usr / local

######## Installation mhash
cd ..
tar -zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9
./configure
sudo make
sudo make install

######### Install mcrypt
cd ..
tar -zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8
LD_LIBRARY_PATH = / usr / local / lib ./configure
sudo make
sudo make install
Compile and install:

cd Downloads /
wget http://labfile.oss.aliyuncs.com/php-5.5.21.tar.gz
tar -zxvf php-5.5.21.tar.gz
cd php-5.5.21
./configure --prefix = / opt / php --with-bz2 --with-curl --with-jpeg-dir --with-gd --enable-shared --enable-mbstring --with-mcrypt - with-mysql = / opt / mysql --with-pdo-mysql = / opt / mysql --with-mysqli = / opt / mysql / bin / mysql_config --enable-fpm --enable-phar --enable-bcmath - -with-zlib --enable-zip --enable-ftp --with-gettext --enable-sockets --with-freetype-dir --with-config-file-path = / opt / php / etc / php. ini --with-config-file-scan-dir = / opt / php / etc / conf.d --with-apxs2 = / opt / apache / bin / apxs
sudo make
sudo make install
sudo cp php.ini-production /opt/php/etc/php.ini
Check whether to support php mysql:

/ Opt / php / bin / php -m | grep mysql

Modify the apache configuration file, add php supported configurations:

sudo sh -c 'cat >> /opt/apache/conf/httpd.conf < < EOF
< IfModule mime_module>
AddType application / x-httpd-php .php
< / IfModule>
EOF '
If you close the open apache, otherwise restart apache:

sudo / opt / apache / bin / apachectl -k restart
test:

sudo sh -c 'echo "< php echo phpinfo ();??>"> /opt/apache/htdocs/test.php'
In the browser, enter:

http: //localhost/test.php

Adding third-party modules

Manually compile Apache modules using apxs:

Apxs on some presentation and data see here.
Here in metadata module, for example:

cd ~ / Downloads / httpd-2.2.29 / modules / metadata
sudo / opt / apache / bin / apxs -i -a -c mod_headers.c
################################################## #########
-c: This option indicates the compilation operation. It first compiles the C source files (.c) files into corresponding object code files (.o), and then connect these object files plus the remaining object files (.o and .a), to generate a dynamic shared object dsofile. If you do not specify a -o option, the output file name obtained from the files of the first file name speculation, therefore, by default, it will generally be mod_name.so
-i: This option indicates the installation operation and installs one or more dynamically shared objects into the modules directory on the server.
-a: This option automatically adds a file in httpd.conf LoadModule line to activate this mode block ## title ##, or, if it already exists, it is enabled.
################################################## #########
Use phpize manually compile PHP modules:

cd ~ / Downloads / php-5.5.21 / ext / ftp
/ Opt / php / bin / phpize
./configure --with-php-config = / opt / php / bin / php-config
sudo make
sudo make install
Load module in php.ini:

sudo sh -c 'echo "extension = ftp.so" >> /opt/php/etc/php.ini'

Options Detailed parameters:

All means all properties except for MultiViews. This is the default setting Options command.
None said they did not enable any server features.
FollowSymLinks allows the server to use symbolic links in this directory. If the configuration option is located in the configuration section, it will be ignored.
Indexes If you enter the URL corresponds to a file directory on the server, and this directory has no DirectoryIndex directive
MultiViews are allowed mod_negotiation module offers consultations "multi-view." If the path is requested by the client may correspond to various types of files, the server will automatically choose a file that best matches the requirements of the client according to the specific circumstances of the client request.
Users SymLinksIfOwnerMatch server only the owner has the same symbolic link to the target file or directory of ID when using it. Only when the symbolic link and a symbolic link the owner of the target file or directory to the same user, will use symbolic links.
ExecCGI allowed mod_cgi module execute CGI scripts.
Includes permitted mod_include module provides server-side includes features
IncludesNOEXEC allow server side includes, but disable the "#exec cmd" and "#exec cgi". But you can still use "#include virtual" virtual CGI scripts from ScriptAlias directory.
