centos 编译安装php

发表于 | 分类于 | | 阅读数

个人还是更喜欢使用Ubuntu apt-get官方源更新的比较快 基本与php新版本同步 而在centos中官方源的php版本严重停滞 所以需要编译安装php 下面是安装流程
同时学习开发php扩展之前必须先学会php的编译安装,php扩展开发可以使得php使用c里面写的函数,和c++里定义的类,使得php更加强大

首先在php官网下载 php的源码包php国内官网

cd 进入源码包

—安装php的依赖包—

yum install epel-release //扩展包更新包
yum update //更新yum源
yum install libmcrypt libmcrypt-devel mcrypt mhash
yum install -y libxml2 libxml2-devel openssl openssl-devel libcurl-devel libjpeg-devel libpng-devel libicu-devel openldap-devel

—编译和安装—

./configure 帮你创建Makefile文件

./configure –prefix=/usr/local/php56 –with-config-file-path=/usr/local/php56/etc –enable-fpm –with-fpm-user=www –with-fpm-group=www –enable-mysqlnd –with-mysql=mysqlnd –with-mysqli=mysqlnd –with-pdo-mysql=mysqlnd –enable-opcache –enable-mbstring –enable-soap –enable-zip –enable-bcmath –with-openssl –with-zlib –with-curl –with-gd –with-zlib-dir=/usr/lib –with-png-dir=/usr/lib –with-jpeg-dir=/usr/lib –with-mhash –with-mcrypt

编译和安装

make && make install

配置 PHP

配置文件：

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

php-fpm 服务:

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm

启动 php-fpm

service php-fpm start
Starting php-fpm done

添加 PHP 命令到环境变量

编辑 ~/.bash_profile，将：

PATH=$PATH:$HOME/bin
改为：
PATH=$PATH:$HOME/bin:/usr/local/php/bin

使 PHP 环境变量生效：

source .bash_profile

三，安装PHP扩展
生成redis.so:
复制代码

9
unzip phpredis-Version

cd phpredis-Version

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make && make install

复制代码

将extension=redis.so加入到php.ini

重启服务器，查看phpinfo();

如果是使用php-fpm，则需要重启php-fpm:

ps aux|grep php-fpm #查看fpm进程号

kill -USR2 fpm进程号 #平滑重启php-fpm
