Nginx进阶篇·Nginx与Apache2共存

前言

今天接触了一个项目，它只能用Apache2，而且最近PHP8.2也推出了来了，所有想着试试就逝世的态度，结果还挺简单的，只能说配置好，后续再深入了解一下。

因此这里把简单的配置方案做一下。

环境

1. Ubuntu

2. Nginx

3. PHP8.1-FPM

步骤

1.安装Apache2

add-apt-repository ppa:ondrej/apache2
apt install apache2

2.安装PHP8.2-fpm

apt install php8.2-fpm 
apt install libapache2-mod-php8.2

安装完提示有错误，正常，因为80端口被nginx占用了。

3.修改Apache2端口

vim /etc/apache2/ports.conf

修改为如下：

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf

Listen 8081

<IfModule ssl_module>
        Listen 444
</IfModule>
 
<IfModule mod_gnutls.c>
        Listen 444
</IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

同时也要修改 VirtualHost 配置文件中的端口：

vim /etc/apache2/sites-enabled/000-default.conf

修改端口：

<VirtualHost *:8081>

这个时候可以看一下有没有因为端口问题报错。

systemctl restart apache2
systemctl status apache2

返回正常：

             └─124037 /usr/sbin/apache2 -k start

4.为apache2启用php-fpm

a2enmod proxy_fcgi setenvif
a2enconf php8.2-fpm

5.安装PHP模块

apt install php8.2-*

重启apache2

systemctl restart apache2

6.测试

到这边就可以试着用 IP:8081 进行访问了。

vim /var/www/html/index.php

输入：

<?php echo phpinfo();?>

保存退出。

编辑nginx的配置文件：

server {
    listen 80;
    index index.html index.htm index.nginx-debian.html index.php;
    server_name test.xxx.com;

    location / {
    proxy_pass_header Server;
        proxy_pass http://127.0.0.1:8081;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_redirect off;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
    access_log /var/log/nginx/test.xxx.com-access.log;
    error_log /var/log/nginx/test.xxx.com-error.log;    
}

重启nginx

systemctl restart nginx

输入网址就能访问了。

总结

Nginx与Apache2各有优缺点，具体还是要看需求。我查了下资料，Apache2和Nginx共存使其各司其职，没有想象中的那么完美，有一篇文章的结论是 Nginx+PHP-FPM > Apache2+Nginx+PHP-FPM。以后有空验证一下吧。
