11.10/11.11/11.12 PHP5安装

介绍

• 7对早期的discuzs有兼容问题，性能有所提高
• 当前主流版本为5.6/7.1

下载

wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2  下载源码包

• r.aminglinux.com
• 镜像站点：cn2.php.net
• PHP官网www.php.net

解压

tar jxvf php-7.1.6.tar.bz2

安装依赖包

yum install -y libxml2-devel openssl-devel bzip2-devel libjpeg-devel libpng-devel freetype-devel epel-release 
yum install -y libmcrypt-devel

• 根据错误寻找依赖包

安装

cd php-5.6.30
./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
make && make install

配置

cp php.ini-production /usr/local/php/etc/php.ini

• php.ini-development用于开发环境

• php.ini-production 用于生产环境

  /usr/local/php/bin/php -i |less 查看路径

/usr/local/php/bin/php -m 查看加载PHP5调用模块
ls /usr/local/apache2.4/modules/libphp5.so 查看php5装入apache的模块文件

11.13 PHP7安装

安装（与php5不一样点）

cd php-7.1.6 
./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc  --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
	比php5多两个7，少一个with
make && makeinstall

• 安装配置

  cp php.ini-production /usr/local/php7/etc/php.ini

检查

/usr/local/php7/bin/php -m 检查php7加载模块
/usr/local/php7/bin/php -i |less 检查配置文件路径
ls /usr/local/apache2.4/modules/libphp7.so 查看装入apache模块
/usr/local/apache2.4/bin/apachectl -M 查看apache所有模块
vim /usr/local/apache2.4/conf/httpd.conf 查看apache是否调用(/libphp)

• 若是已经装了php5须要注释掉
