Installing PHP5

    介绍:    关于php的版本，目前大多企业都会使用5.4以及更高的版本，甚至越来越多的企业使用PHP7版本。    7和5两个版本还是又很大差异的，7的话有很大的性能提升。    PHP官网：hhtp://www.php.net/downloads.php

First, go to the downloaded directory

    [[email protected] src]# cd /usr/local/src/    [[email protected] src]# pwd    /usr/local/src

Download the source Package

    [[email protected] src]#  wget http://cn2.php.net/distributions/php-5.6.30.tar.gz

Unzip the source package

    [[email protected] src]# tar zxvf php-5.6.30.tar.gz

To compile and install

    ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --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

There are errors, the first installation of a lack of many source packages, first installed one by one

• Error 1
  Configure:error:xml2-config not found. Please check your LIBXML2 installation.
  The solution is as follows:
  Yum Install-y libxml2-devel
• Error 2
  Configure:error:Cannot find OpenSSL ' s <evp.h>
  The solution is as follows:
  Yum Install-y OpenSSL Openssl-devel
• Error 3
  Checking for BZIP2 in default path ... not found
  Configure:error:Please Reinstall the BZIP2 distribution
  The solution is as follows:
  [email protected] php-5.6.30]# Yum install-y bzip2 bzip2-devel
• Error 4
  Configure:error:jpeglib.h not found.
  The solution is as follows:

  The CentOS default yum source does not libmcryot-devel this package, so you can only extend the source with Epel Yum
  Install to Yum package again
  [email protected] php-5.6.30]# Yum install libjpeg.x86_64 libpng.x86_64 freetype.x86_64 libjpeg-devel.x86_64 libpng-devel.x86_64 freetype-devel.x86_64-y compiling the installation again

  [[email protected] php-5.6.30]# ./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-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --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-exifmakemake install

  Finally, the configuration file is copied, as shown in the following example: Configuration httpd support PHPHTTPD Master profile is/usr/local/apache2/conf/httpd.conf

  修改它目的，允许所有请求，如果不设置该行，则我们访问的时候会报错403错误。[[email protected] php-5.6.30]# vim /usr/local/apache2/conf/httpd.conf

• Search servername, the #servicename www.example.com:80 in front of the well to delete, find the following content modification.
  
• Modified to:
  
  Then find 378 lines below add below:
  
  Then find the following paragraph, modified to read as follows:
  
• Modified to:
  Test if lamp is successful

  httpd、MySQL、和PHP安装之后，需要先检验httpd的配置文件是否正确；只有正确配置才可以正确解析文件。

  Test configuration file is correct
• Before starting httpd, you need to verify that the configuration file is correct, as follows:
  
• If it is wrong, please continue to modify the configuration file httpd.conf, if configured correctly, will show "Syntax OK"
• The command to start httpd is as follows:
  [[email protected] php-5.6.30]#/usr/local/apache2/bin/apachectl start
• The command to see whether to start is as follows:
  [Email protected] php-5.6.30]# NETSTAT-LNP |grep httpd
  If this line is displayed and the httpd is started. Test whether the correct parsing of PHP configuration file in 392 add a line so that you can normally parse PHP

First, write a test script first.

    [[email protected] php-5.6.30]# vim /usr/local/apache2/htdocs/1.php    <?php    echo "php解析正常"    ?>
