Nginx如何配置虚拟主机？

2017-01-16技术运维Nginx CentOS 733

你或许还需要了解如何在CentOS7上安装LEMP(Linux+Nginx+MySQL+PHP)环境？

适用于CentOS7操作系统，Nginx建立虚拟主机配置多站点的方法：

Nginx配置

建立主机配置文件存放目录

mkdir /etc/nginx/sites-available
mkdir /etc/nginx/sites-enabled

修改Nginx配置文件

vi /etc/nginx/nginx.conf

找到这一行

include /etc/nginx/conf.d/*.conf;

在它下面加一行

include /etc/nginx/sites-enabled/*.conf;

保存并退出

虚拟主机配置

建立子站点目录

mkdir -p /mnt/www/example1.com/public_html/

建立测试文件

vi /mnt/www/example1.com/public_html/index.php

<?php
echo "<h1>Welcome to example1.com!</h1>";
?>

建立站点配置文件

vi /etc/nginx/sites-available/example1.com.conf

OPTION #1: 建立站点配置文件

server {
    listen 80; 
    root /mnt/www/example1.com/public_html;
    index index.php index.html index.htm;
    
    server_name example1.com www.example1.com;
    
    location / {
        try_files $uri $uri/ /index.html;
    }
    
   
    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /mnt/www/example1.com/public_html;
    }
    
    # pass the PHP scripts to PHP-FPM server listening on 127.0.0.1:9000
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

OPTION #2: 如果使用的是ProcessWire项目则可以使用以下Rewrite规则：

	}


}

建立软连接

 ln -s /etc/nginx/sites-available/example1.com.conf /etc/nginx/sites-enabled/example1.com.conf

使用命令 /usr/sbin/nginx -t 测试conf文件是否有误

[root@localhost public_html]# /usr/sbin/nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

这点很重要！很重要！很重要！重要的事情说三遍，如果某个站点配置出错导致Nginx无法启动会使所有站点全部挂掉，到时候你会比我急，所以最好养成这个习惯，修改配置后先 /usr/sbin/nginx -t 一下！

最后重启Nginx

systemctl restart nginx

如添加更多站点只需要重复分割线以后的步骤即可
