centos php.ini(centos-7)
大家好，今天来为大家分享centos php.ini的一些知识点，和centos-7的问题解析，大家要是都明白，那么可以忽略，如果不太清楚的话可以看看本篇文章，相信很大概率可以解决您的问题，接下来我们就一起来看看吧！
Centos7如何安装PHP7最新版
方法一、简单安装(通过yum)
1.安装epel-release
rpm-ivh
2.安装PHP7的rpm源
rpm-Uvh
3.安装PHP7
yum install php70w
方法二、编译安装
1.下载php7
wget-O php7.tar.gz
2.解压php7
tar-xvf php7.tar.gz
3.进入php目录
cd php-7.0.4
4.安装依赖包
#直接复制下面一行(不包括本行)
yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel
5.编译配置(如果出现错误，基本都是上一步的依赖文件没有安装所致)
嫌麻烦的可以从这一步起参考PHP官方安装说明：
./configure\
--prefix=/usr/local/php\
--with-config-file-path=/etc\
--enable-fpm\
--with-fpm-user=nginx\
--with-fpm-group=nginx\

6.正式安装
make make install
7.配置环境变量
vi/etc/profile
在末尾追加
PATH=$PATH:/usr/local/php/bin
export PATH
执行命令使得改动立即生效
source/etc/profile
8.配置php-fpm
cp php.ini-production/etc/php.ini
cp/usr/local/php/etc/php-fpm.conf.default/usr/local/php/etc/php-fpm.conf
cp/usr/local/php/etc/php-fpm.d/www.conf.default/usr/local/php/etc/php-fpm.d/www.conf
cp sapi/fpm/init.d.php-fpm/etc/init.d/php-fpm
chmod+x/etc/init.d/php-fpm
9.启动php-fpm
/etc/init.d/php-fpm start
[php教程]请教linux下php的配置文件在什么地方
PHP开源脚本语言
PHP（外文名: Hypertext Preprocessor，中文名：“超文本预处理器”）是一种通用开源脚本语言。语法吸收了C语言、Java和Perl的特点，入门门槛较低，易于学习，使用广泛，主要适用于Web开发领域。PHP的文件后缀名为php。
本文讲解了如何在linux下找出PHP配置文件php.ini的路径的方法,很多linux新手都不知道php安装在哪里,需要修改php.ini但是找不到在哪里,本文讲解的方法其实就是使用phpinfo()函数输出PHP信息,然后找到Configuration File(php.ini) Path这节就可以了,感兴趣的同学参考下.
近来，有不博友问php.ini存在哪个目录下？或者修改php.ini以后为何没有生效？基于以上两个问题，我觉得有必要教一下刚接触PHP的博友们如何找到PHP调用php.ini的路径目录。
一般安装PHP环境无非有两种平台，Linux环境下与WIN平台下。而WIN平台居多，因为现在套装安装包非常方便，如appserv、wamp一件安装包等等。而Linux下也有LNMP一键安装包，非常方便。由于这些安装做了简化，所以自然的许多博友就不太清楚环境安装好了以后php.ini放在哪个目录下，或者在某个目录下找到了php.ini文件但不知是否是PHP程序调用的那个。
我们可以通过phpinfo查找php.ini路径
新建一个php页面，输入:
[code]
<?php phpinfo();?>
[code]
保存退出
使用浏览器访问页面，会看到是一个PHP配置信息的相关页面
找到Configuration File(php.ini) Path这一行
右边的值/usr/local/webserver/php/etc就是php.ini文件所在目录
最后修改以后要记得重启相关程序才能生效。
阿里云上的centos 7.2怎么yum安装php 5.6
因之前通过网易的 centos镜像，将阿里云的 centos升级到最新版了，乘自己的项目尚未开始正式开发，遂将所有的相应环境都升级到最高。
查看 centos版本：
[root@iZ23d~]# cat/etc/centos-release
CentOS Linux release 7.2.1511(Core)
1、删除之前的 php版本：
[root@iZ23d~]# yum remove php* php-common
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration
No Match for argument: php-5.4.16
No Match for argument: php-5.4.16.tar.gz
No Match for argument: php-7.0.1RC1
No Match for argument: php-7.0.1RC1.tar.gz
No Match for argument: phpMyAdmin-4.4.0.tar.gz
No Match for argument: php-common
No Packages marked for removal
2、rpm安装 Php7相应的 yum源：
[root@iZ23d~]# rpm-Uvh
Retrieving

Preparing...################################# [100%]
package webtatic-release-7-3.noarch is already installed
3、直接yum安装php7：
[root@iZ23d~]# yum install php70w
Loaded plugins: langpacks
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration

4、检查 php版本：
[root@iZ23d~]# php-v
PHP 7.0.0(cli)(built: Dec 2 2015 20:42:32)( NTS)

[root@iZ23d2e6hoqZ~]#
以上显示安装成功！
5、重启 Apache，查看 phpinfo:
[root@iZ23d~]# systemctl restart httpd.service
检查phpinfo:
