centos65yum升級php_阿里雲上的centos 72怎麼yum安裝php 56

1. centos7系統Apache+php+mysql環境，怎麼升級PHP版本

yum install php php-devel
重啟apache使php生效
systemctl restart httpd.service
此時可以在目錄：/var/www/html/下建立一個PHP文件
代碼：
<?php phpinfo(); ?>

然後訪問這個文件，就能看到PHP的一些信息，php.ini配置文件的路徑可以在這個頁面上看到

安裝php的擴展
yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc
安裝完擴展之後需要再次重啟apache
systemctl restart httpd.service

2. 阿里雲上的centos 7.2怎麼yum安裝php 5.6

因之前通過網易的 centos 鏡像，將阿里雲的 centos 升級到最新版了，乘自己的項目尚未開始正式開發，遂將所有的相應環境都升級到最高。
查看 centos 版本：
[root@iZ23d ~]# cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)
1、刪除之前的 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 安裝 Php7 相應的 yum源：
[root@iZ23d ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
Retrieving https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Preparing... ################################# [100%]
package webtatic-release-7-3.noarch is already installed
3、直接yum安裝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

Complete!
4、檢查 php 版本：
[root@iZ23d ~]# php -v
PHP 7.0.0 (cli) (built: Dec 2 2015 20:42:32) ( NTS )
Copyright (c) 1997-2015 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies
[root@iZ23d2e6hoqZ ~]#
以上顯示安裝成功！
5、重啟 Apache，查看 phpinfo :
[root@iZ23d ~]# systemctl restart httpd.service
檢查phpinfo:

以上顯示 php7 安裝成功！

3. 如何在CentOS 6.5上升級PHP版本

在更新PHP之前，先查看下當前PHP版本，避免重復的更新
# php -v
檢查當前PHP的安裝包
# yum list installed | grep php
移除當前PHP的安裝包，否則容易起沖突
# yum remove php*
由於默認的YUM源無法升級PHP，所以需要添加第三方的YUM源，此處用到webtatic。
因為是CentOS 6.5，所以用以下URL
# rpm -Uvh yum/el6/latest.rpm
如果是CentOS 7.x
rpm -Uvh yum/el7/epel-release.rpm
rpm -Uvh yum/el7/webtatic-release.rpm
查看YUM源上能用PHP安裝包
＃ yum list php*
安裝PHP5.5及需要的擴展
# yum install php55w php55w-devel php55w-common php55w-mysql php55w-pdo php55w-opacache php55w-xml
再次查看PHP版本，以確認安裝是否成功
對了，如果你的PHP要用到Redis，請別忘了安裝php-redis 擴展
＃ yum install php-redis

4. CentOS 6.5 使用yum安裝lamp環境 php是5.3.3的太低了

簡單介紹一下，如何在CentOS上安裝PHP5.6。
配置yum源
追加CentOS 6.5的epel及remi源。

#rpm-Uvh
#rpm-Uvh

以下是CentOS 7.0的源。

#yuminstallepel-release
#rpm-ivh

使用yum list命令查看可安裝的包(Packege)。

#yumlist--enablerepo=remi--enablerepo=remi-php56|grepphp

安裝PHP5.6
yum源配置好了，下一步就安裝PHP5.6。

#yuminstall--enablerepo=remi--enablerepo=remi-php56phpphp-opcachephp-develphp-mbstringphp-mcryptphp-mysqlndphp-phpunit-PHPUnitphp-pecl-xdebugphp-pecl-xhprof

用PHP命令查看版本。

#php--version
PHP5.6.0(cli)(built:Sep3201419:51:31)
Copyright(c)1997-2014ThePHPGroup
ZendEnginev2.6.0,Copyright(c)1998-2014ZendTechnologies
withZendOPcachev7.0.4-dev,Copyright(c)1999-2014,byZendTechnologies
withXdebugv2.2.5,Copyright(c)2002-2014,byDerickRethans

在這里安裝的版本是PHP5.6.0，細心的用戶可能已經發現ZendGuardLoader變成Zend OPcahe了。
對從PHP5.5開始PHP代碼緩存從APC變成了Zend OPcache了。
