我收到错误消息:

FastCGI sent in stderr: "Unable to open primary script: /home/messi/web/wordpress/index.php (No such file or directory)" while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: www.domain.com, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "www.domain.com

在/ etc/nginx的/启用的站点 - /WordPress的

server {
    listen   80;
    server_name www.domain.com;
    root /home/messi/web/wordpress;
    error_log /var/log/nginx/err.wordpress.log;
    index index.php;
    location / {
        try_files $uri $uri/ /index.php?$args;
    }
    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }
    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }
    location ~ /\. {
        deny all;
    }
    location ~* /(?:uploads|files)/.*\.php$ {
        deny all;
    }
    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include /etc/nginx/fastcgi_params;
    }
}

设置用户权限:

#adduser www-data messi
#chown -R www-data:www-data /home/messi/web
#chmod -R 664 /home/messi/web/wordpress

我该如何解决这个问题？谢谢

Answer 1

SELinux默认会在CentOS/RHEL 7+上导致此错误:(

要测试SELinux是否是您困境的根源,请执行此操作

setenforce 0

......看看一切是否有效.如果修复它,你可以关闭SELinux(弱,你比那更好),或者你可以把它重新打开

setenforce 1

......然后妥善解决问题.

如果你这样做

tail -f /var/log/audit/audit.log

......你会看到SELinux问题.就我而言,它拒绝PHP-FPM访问Web文件.您可以运行以下指令来修复它:

setsebool -P httpd_can_network_connect_db 1
setsebool -P httpd_can_network_connect 1

这实际上一开始并没有为我修复它,但是然后恢复SELinux上下文就做到了

restorecon -R -v /var/www

希望有所帮助.

这可能是权限问题.

1. 确保每个父目录对用户(nginx用户和/或php-fpm用户)具有+ x权限.

   您可以检查这些权限有:namei -om /path/to/file.

2. 如果您有符号链接,请确保它们指向有效路径.

3. 确保chroots可以访问正确的路径.

4. 确保SELinux(例如Fedora/Centos)或AppArmor(例如Ubuntu)或任何其他MAC安全系统不干扰文件访问.

   对于SeLinux:检查/var/log/audit/audit.log或/ var/log/messages

   对于AppArmor:我不是Ubuntu用户,据我所知,AppArmor的日志记录并不容易弄清楚.您可以在此处查看信息:http://ubuntuforums.org/showthread.php？t = 1733231
