下载并解压php7源码包：
https://www.php.net/downloads.php

2. 文件php-7.3.8.tar.gz放在/usr/local/src
3. tar -zxvf /usr/local/src/php-7.3.8.tar
4. mkdir /usr/local/zwk_php
mv /usr/local/src/php-7.3.8 /usr/local/zwk-php
5. cd /usr/local/zwk-php
./configure --prefix=/usr/local/zwk_php --with-apxs2=/usr/local/zwk_apache/httpd-2.4.41/bin/apxs --with-config-file-path=/usr/local/zwk_php/etc --with-mysql=/usr/local/zwk_mysql --with-pdo-mysql=/usr/local/zwk_mysql --with-mysqli=/usr/local/zwk_mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif

在上一步编译PHP的过程中，我遇到了这些错误：
configure: error: xml2-config not found. Please check your libxml2 installation.
安装所需的包然后继续编译：
yum install -y libxml2-devel

configure: error: Cannot find OpenSSL’s <evp.h>
安装所需的包然后继续编译：
yum install -y openssl openssl-devel

configure: error: Please reinstall the BZip2 distribution
安装所需的包然后继续编译：
yum install -y bzip2 bzip2-devel

configure: error: jpeglib.h not found.
安装所需的包然后继续编译：
yum install -y libpng libpng-devel

configure: error: freetype-config not found.
安装所需的包然后继续编译：
yum install -y freetype freetype-devel

configure: error: mcrypt.h not found. Please reinstall libmcrypt.
安装所需的包然后继续编译：
yum install -y epel-release
yum install -y libmcrypt-devel

继续编译

出现这样的提示信息，这就说明PHP7配置编译参数完成。

由于没有设置swap大小或设置内存太小，编译程序会出现virtual memory exhausted: Cannot allocate memory的问题，可以用swap扩展内存的方法。
在执行free -m的是时候提示Cannot allocate memory:

（swap文件可以放在自己喜欢的位置如/var/swap）

[root@Byrd byrd]# free -m
total used free shared buffers cached
Mem: 512 108 403 0 0 28
-/+ buffers/cache: 79 432

[root@Byrd ~]# mkdir /opt/images/
[root@Byrd ~]# rm -rf /opt/images/swap

内存太小，增加内存可以解决。
使用完毕后可以关掉swap：

[root@hz mnt]# swapoff swap
[root@hz mnt]# rm -f /opt/images/swap
swap文件也可以不删除，留着以后使用，关键是你的虚拟机硬盘够用。

接下来就是编译和安装：
make
make install

然后把配置文件放到/usr/local/php7/etc/目录下改名为php.ini：

cp php.ini-production /usr/local/php7/etc/php.ini

安装完成以后，我们可以查看：
#ls /usr/local/zwk_apache/httpd/modules/libphp*
/usr/local/apache2.4/modules/libphp7.so

查看httpd中有没有加载PHP模块：

/usr/local/zwk_apache/httpd /bin/apachectl -M

Loaded Modules:

可以看到，已经加载PHP7模块。

查看PHP7加载的模块（都是静态模块）：

/usr/local/zwk_php/bin/php -m

查看PHP信息：

/usr/local/zwk_php/bin/php -i

11.4 Apache和PHP结合

httpd的主配置文件是 /usr/local/zwk_apache/httpd/conf/httpd.conf，对于这个文件，我们要做4处修改：

vim /usr/local/zwk_apache/httpd /conf/httpd.conf #做下面修改

ServerName www.example.com:80

AllowOverride none Require all granted #目的是允许所有请求，如果不做修改则访问时候会显示403错误

AddType application/x-gzip .gz .tgz
AddType application/x-httpd-php .php #注意php和.php之间有空格

DirectoryIndex index.html index.php

配置完成，保存退出。

可以测试一下配置语法是否正确：

/usr/local/zwk_apache/httpd /bin/apachectl -t

Syntax OK
说明配置语法没问题。

然后重新加载配置文件：

/usr/local/zwk_apache/httpd /bin/apachectl graceful

启动服务：

/usr/local/zwk_apache/httpd /bin/apachectl start

查看是否启动：

netstat -lntp | grep 80

tcp6 0 0 :::80 ::
