Lamp Installation and Precautions

Lamp--linux+apache (httpd) +mysql+php, which is a common Web server architecture, accepts the process of compiling the installation and the errors that occur.

Precautions:

1. Extended Epel Source: reference: http://www.cnblogs.com/llius/p/5105051.html

2. PHP is installed behind MySQL and httpd, because it relies on both paths when compiling

3. Firewall off: iptables-f---Service iptables Save (CENTOS7 does not support save); vim/etc/selinux/config:selinux=enforcing--SELI Nux=disabled-Reboot

Test environment:

centos_6.6 64-bit && centos_7.0 64-bit pro-Test effective!!!

Three software versions (although the version is older, it is better for practiced hand):

httpd-2.2.24.tar.bz2

MYSQL-5.1.73-LINUX-X86_64-GLIBC23.TAR.GZ//non-woven, MySQL is too big, compile time, you can choose to skip the package

php-5.4.44.tar.bz2

To extend the library resources, some packages need to extend the Epel source:

Yum install-y gcc gcc-c++ make zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freet Ype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel Curl Curl-deve L e2fsprogs e2fsprogs-devel krb5-devel OpenSSL openssl-devel openldap openldap-devel openldap-clients openldap-servers Libmcrypt libmcrypt-devel Libaio libaio-devel openssl*

First, the installation of MySQL:

1. New environment without MySQL user, add a MySQL user

# useradd-s/sbin/nologin-m MySQL    //-m: Do not generate home directory-s/sbin/nologin

2. Create a new MySQL data directory and assign ownership to MySQL

# mkdir-p/data/mysql# chown-r mysql.mysql!$

3. Download mysql-5.1.73-linux-x86_64-glibc23.tar.gz, unzip, move rename, change owner to MySQL

# cd/usr/local/src# wget http://mirrors.sohu.com/mysql/MySQL-5.1/mysql-5.1.73-linux-x86_64-glibc23.tar.gz# Tar- ZXVF mysql-5.1.73-linux-x86_64-glibc23.tar.gz# MV Mysql-5.1.73-linux-x86_64-glibc23.tar.gz. /mysql# chown-r Mysql.mysql!$

4. Initialize (display two OK, indicating success of initialization):

# cd/usr/local/mysql#./scripts/mysql_install_db--user=mysql--datadir=/data/mysql--basedir=/usr/local/mysql

5. configuration file copy and edit:

# cd/usr/local/mysql/support-files# CP mysql.server/etc/init.d/mysqld//   startup script # Vim!$    //Edit the following parameters: basedir=/usr/ local/mysqldatadir=/data/mysql# CP my-small.cnf/etc/my.cnf  //config file #/etc/init.d/mysqld start# PS aux |grep mysqld< c3/>//has mysqld process, indicating successful installation

Ii. installation of Apache (HTTPD)

1. Download and unzip the httpd-2.2.24.tar.bz2:

# cd/usr/local/src/# wget http://www.lishiming.net/data/attachment/forum/httpd-2.2.24.tar.bz2# TAR-JXVF httpd-2.2.24.tar.bz2# CD!$

2. Configure the compilation parameters:

./configure--prefix=/usr/local/apache2--with-included-apr--enable-so \     //extension useful for PHP--enable-deflate=shared-- enable-expires=shared--enable-rewrite=shared--with-pcre

3. Compiling and installing

# Make && make install

Third, the installation of PHP

1. Download, unzip

# cd/usr/local/src# wget http://cn2.php.net/distributions/php-5.4.44.tar.gz# tar zxvf php-5.4.44.tar.gz

2. Configure the compilation parameters:

./configure--prefix=/usr/local/php--with-apxs2=/usr/local/apache2/bin/apxs--with-config-file-path=/usr/local/ Php/etc--with-mysql=/usr/local/mysql--with-libxml-dir--with-gd--with-jpeg-dir--with-png-dir--with-freetype-dir --with-iconv-dir--with-zlib-dir--with-bz2--with-openssl--with-mcrypt--enable-soap--enable-gd-native-ttf-- Enable-mbstring--enable-sockets--enable-exif--disable-ipv6

3. Compiling and Installing:

# Make && make install

Iv. adding PHP parsing in Apache

1. Copy the PHP configuration file:

# Cp/usr/local/src/php-5.4.44/php.ini-production/usr/local/php/etc/php.ini

2. Modifying the Apache configuration file

# vim/usr/local/apache2/conf/httpd.conf found: <directory/>options followsymlinksallowoverride NoneOrder deny, Allowdeny from all   //deny-allow</directory> found: AddType application/x-gzip. gz. tgz  ///Added below: AddType application/x-httpd-php. php Find: <ifmodule dir_module>    directoryindex index.html     //Add later: index.htm Index.php</ifmodule> found: #ServerName www.example.com:80   //Remove comments, instead: ServerName localhost:80

3. Turn on httpd service

#/usr/local/apache2/bin/apachectl-t   //Show Syntax OK, no problem with configuration file #/usr/local/apache2/bin/apachectl start   // Start Service # PS aux |grep httpd  //See if there is a httpd process

4. Test PHP parsing

# cd/usr/local/apache2/htdocs  //apache file default directory # VIM index.php  //write the following: <?phpecho "hello!"? > Save exit
Browser input: 192.168.220.22\index.php    //Host IP and PHP file name

If you open a Web page that displays hello! , does not eject the download PHP interface, also does not display <?php echo "hello!", explains the PHP parse succeeds.
