centos7下如何安装php7的openssl扩展（centos7安装php5.6）

在CentOS 7下安装PHP 7的openssl扩展，可以按照以下步骤进行操作：

1、安装EPEL源

运行以下命令安装EPEL源：

```

sudo yum install epelrelease

```

2、安装依赖库

运行以下命令安装必要的依赖库：

```

sudo yum install openssldevel zlibdevel pcredevel

```

3、下载PHP源码

访问PHP官方网站（https://www.php.net/downloads.php）下载最新的PHP 7源码包，选择适用于您的系统的tar.gz文件并下载到本地。

4、解压PHP源码包

使用以下命令将下载的PHP源码包解压到一个目录中（/usr/local/php）：

```

sudo tar zxvf php7.x.x.tar.gz C /usr/local/php

```

注意替换 "php7.x.x.tar.gz" 为您实际下载的文件名。

5、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/php/php7.x.x

```

同样，替换 "php7.x.x" 为您实际解压的目录名。

6、配置编译选项

运行以下命令配置编译选项：

```

sudo ./configure withopenssl withzlib withpcre prefix=/usr/local/php

```

这将启用openssl、zlib和pcre扩展，并将PHP安装到 /usr/local/php 目录下。

7、编译并安装PHP

运行以下命令开始编译和安装PHP：

```

sudo make && sudo make install

```

这将编译并安装PHP及其扩展。

8、配置Apache或Nginx以使用PHP

根据您使用的Web服务器（Apache或Nginx），编辑相应的配置文件以启用PHP模块，以下是针对Apache和Nginx的示例配置：

对于Apache：

打开Apache的httpd.conf文件：

```

sudo vi /etc/httpd/conf/httpd.conf

```

在文件末尾添加以下内容：

```

Include conf/extra/php7_module.conf

Include conf/extra/php7_module.load

```

创建一个新的文件 /etc/httpd/conf/extra/php7_module.conf，并添加以下内容：

```

LoadModule php7_module modules/libphp7.so

AddType application/xhttpdphp .php

PHPIniDir /usr/local/php/etc/php.ini

```

重新启动Apache服务：

```

sudo systemctl restart httpd

```

对于Nginx：

打开Nginx的nginx.conf文件：

```

sudo vi /etc/nginx/nginx.conf

```

在文件末尾添加以下内容：

```

include /usr/local/php/etc/nginx/*.conf;
