linux升级php版本

在Linux系统中，可以通过以下命令升级PHP版本：1. 首先更新系统软件包；2. 然后安装新版本的PHP及其扩展。

在 Linux 下升级 PHP，可以按照以下步骤进行操作：

1、检查当前 PHP 版本：

打开终端，输入以下命令查看当前 PHP 版本：

“`

php v

“`

2、更新系统软件包：

运行以下命令更新系统软件包列表：

“`

sudo apt update

“`

3、安装依赖项：

运行以下命令安装升级 PHP 所需的依赖项：

“`

sudo apt install buildessential libxml2dev libssldev zlib1gdev libzipdev libcurl4openssldev libjpegdev libpngdev libfreetype6dev libonigdev libreadlinedev libsqlite3dev libmysqlclientdev phppear php7.4dev

“`

4、下载 PHP 源码：

访问 PHP 官方网站（https://www.php.net/downloads.php）下载最新版本的源代码压缩包，选择与您的 Linux 发行版和体系结构匹配的版本。

5、解压 PHP 源码：

将下载的压缩包解压到您选择的目录中，/usr/local/src：

“`

tar zxvf phpx.y.z.tar.gz C /usr/local/src/

“`

x.y.z 是下载的 PHP 版本号。

6、进入 PHP 源码目录：

使用以下命令进入解压后的 PHP 源码目录：

“`

cd /usr/local/src/phpx.y.z/

“`

7、配置编译选项：

运行以下命令配置编译选项：

“`

./configure prefix=/usr/local/php withconfigfilepath=/usr/local/php/etc enablefpm withfpmuser=wwwdata withfpmgroup=wwwdata enablembstring withcurl withopenssl withzip withmysqli withpdo_mysql enablesoap enablesockets enablesysvsem enablesysvshm enablepcntl enableexif enablebcmath enablecalendar enableftp enableintl withgettext withgd withjpegdir=/usr/include/ withpngdir=/usr/include/ withfreetypedir=/usr/include/ withzlib withmcrypt enableopcache enablexmlreader enablexmlwriter enablesimplexml disablerpath enableshared=yes enablecli=yes

“`

根据您的需求，可以根据需要启用或禁用其他功能。

8、编译并安装 PHP：

运行以下命令开始编译和安装 PHP：

“`

make && make install

“`

这将花费一些时间来完成编译过程。

9、添加新 PHP 版本的软链接：

运行以下命令将新安装的 PHP 添加到系统的可执行路径中：

“`

echo "/usr/local/php/bin" | sudo tee a /etc/environment > /dev/null && source /etc/environment && echo "export PATH=$PATH:/usr/local/php/bin" | sudo tee a /etc/profile > /dev/null && source /etc/profile && sudo updatealternatives install /usr/bin/php php /usr/local/php/bin/php* 100 && sudo updatealternatives set php /usr/local/php/bin/php* && which php && ls l $(which php) && ls l $(which fpm) && ls l $(which cgi) && ls l $(which fastcgi) && ls l $(which phar) && ls l $(which shim) && ls l $(which composer) && ls l $(which opcache) && ls l $(which xdebug) && ls l $(which yac) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fpm) && ls l $(which fPMEngINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGINEeNGILEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEENEEGEE
