Build a LAMP environment in CentOS

Preface:This section describes how to build a LAMP environment in CentOS (all use source code compilation and installation) for web server development.

LAMP:Linux + Apache + PHP + Mysql. System:CentOS 7, 64-bit. CentOS Installation

I have selected the 64-bit CentOS 7 Linux system. The installation process is also very simple. I will not describe it too much. I will just give a brief introduction to my partitions:

Partition name	Size
/Boot	200 MB
/Swap	8 GB (not greater than the physical partition)
/	20 GB
/Home	Remaining Space

Apache compilation and Installation

I have selected httpd 2.2. For more information, see the official instructions.

Install dependency:

The gcc and g ++ compilers required for installing dependencies:

########gcc、g++sudo yum install gcc sudo yum install gcc-c++

The following two are apache optimization tools:

########aprwget http://labfile.oss.aliyuncs.com/apr-1.5.1.tar.gztar -zxvf apr-1.5.1.tar.gzcd apr-1.5.1/./configure --prefix=/opt/aprsudo make && make install

########apr-utilcd Downloads/wget http://labfile.oss.aliyuncs.com/apr-util-1.5.4.tar.gztar -zxvf apr-util-1.5.4.tar.gzcd apr-util-1.5.4./configure --prefix=/opt/apr-util --with-apr=/opt/aprsudo make && make install

Perl library, compatible with Regular Expression Library:

cd Downloads/wget http://labfile.oss.aliyuncs.com/pcre-8.36.tar.gztar -zxvf pcre-8.36.tar.gzcd pcre-8.36./configure --prefix=/opt/pcresudo make && make install

Install apache:

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

Test:

Start:

sudo /opt/apache/bin/apachectl start

Obtain the Server Response (the server has been set as localhost In the last step of apache installation ):

curl -I 127.0.0.1

If the installation is successful, it is as follows:


Close:

sudo /opt/apache/bin/apachectl stop

Install and compile MySQL dependencies:

Note:MySQL and later versions use cmake for compilation.

Secret file rm-f CMakeCache.txt sudo yum-y install gcc-c ++ autoconf automake zlib * fiex * libxml * ncurses-devel libmcrypt * libtool-ltdl-devel * cmake-gui libaio-devel bison-devel make

Compilation and installation (Long Time ):

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

Create a 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/datasudo /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 <<EOFbasedir = /opt/mysqldatadir = /opt/mysql/datalog-error = /opt/mysql/data/error.logpid-file = /opt/mysql/data/mysql.pidport = 3306EOF'

Clear residual files:

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

Start:

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

If the operation is successful, the following information is displayed:


Test:

/opt/mysql/bin/mysqladmin ping

If the operation is successful, the following information is displayed:


View the database:

/opt/mysql/bin/mysql -u root -e 'show databases;'

Close:

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

If the operation is successful, the following information is displayed:


PHP compilation, installation, and installation dependencies:

The last three files can be downloaded from here.

Check whether php supports mysql:

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

If yes, the following information is displayed:


Modify the apache configuration file and add the supported php configuration:

sudo sh -c 'cat >> /opt/apache/conf/httpd.conf <<EOF<IfModule mime_module>AddType application/x-httpd-php .php</IfModule>EOF'

If it is disabled, enable apache; otherwise, restart apache:

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

Test:

sudo sh -c 'echo "<?php echo phpinfo(); ?>" > /opt/apache/htdocs/test.php'

Enter in the browser:

http://localhost/test.php

If the configuration is successful, the php information is displayed:


Add a third-party module and use apxs to manually compile the Apache module:

For more information about apxs and its parameters, see here.
The metadata module is used as an example:

Cd ~ /Downloads/httpd-2.2.29/modules/metadatasudo/opt/apache/bin/apxs-I-a-c mod_headers.c ################# ######################################## #-c: this option indicates that the compilation operation is required. It will first compile the C source program (. c) files is the target code file (. o), then, connect the target code and other target code files in files (. o and. a) To generate a dynamic shared object dsofile. If the-o option is not specified, the output file name is inferred from the first file name in files, so it is typically a mod_name.so-i: This option indicates the installation is required, to install one or more dynamic shared objects to the modules directory of the server. -A: This option automatically adds a LoadModule row to the httpd. conf file to activate the Module # title #. Or, if this row already exists, it is enabled. ######################################## ###################

Use phpize to manually compile the PHP module:

cd ~/Downloads/php-5.5.21/ext/ftp/opt/php/bin/phpize./configure --with-php-config=/opt/php/bin/php-configsudo makesudo make install

Load the module in php. ini:

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

Apache configuration:

Apache main configuration file/opt/apache/conf/httpd. conf:

# Apache service root directory ServerRoot "/opt/apache" # service administrator ServerAdmin you@example.com # listening port Listen 80 # default homepage DirectoryIndex index. php # Load php module LoadModule php5_module modules/libphp5.so # parse phpAddType application/x-httpd-php. php

# Directory permission parameter DocumentRoot "/opt/apache/htdocs" # WEB file root Directory <Directory "/opt/apache/htdocs"> # official document link http://httpd.apache.org/docs/2.2/mod/core.html Options Indexes FollowSymLinks AllowOverride None Order allow, deny Allow from all # Allow all requests </Directory>

AllowOverride parameters:

None does not allow. htaccess to use any commands. AuthConfig allows all permission commands, including AuthDBMGroupFile AuthDBMUserFile AuthGroupFile AuthName AuthTypeAuthUserFile and Require. FileInfo allows commands of the file control type. Including AddEncoding AddLanguage AddType DEfaultType ErrorDocument extends agepriority. Indexes allows commands of the Directory control type. Including AddDescription AddIcon AddIconByEncoding AddIconByType DefaultIcon DirectoryIndex FancyIndexing HeaderName IndexIgnore IndexOptions ReadmeName. Limit allows you to use permission control commands. Including Allow Deny and Order. Options allows commands that control directory features, including Options and XBitHack.

Options parameters:

All indicates All features except MultiViews. This is also the default setting of the Options command. None indicates that no server features are enabled. The FollowSymLinks server allows symbolic connections in this directory. If this configuration option is in the configuration segment, it will be ignored. Indexes if the entered URL corresponds to a file directory on the server, and there is no DirectoryIndex command MultiViews in this directory, the mod_negotiation Module is allowed to provide "multi-view" for content negotiation ". If the path requested by the client may correspond to multiple types of files, the server automatically selects the file that best matches the requirements of the client according to the specific request of the client. The SymLinksIfOwnerMatch server is used only when the symbolic connection has the same user ID as the owner of the target file or directory. The symbolic connection is used only when the owner of the target file or directory to which the symbolic connection points is the same user. ExecCGI allows the use of the mod_cgi module to execute CGI scripts. Includes allows the mod_include module to provide the server-side inclusion function IncludesNOEXEC allows the server-side inclusion, but disables "# exec cmd" and "# exec cgi ". However, you can still use the "# include virtual" virtual CGI script from the ScriptAlias directory.
