所以我有一台Ubuntu服务器,我正试图从备份中恢复。当一个虚拟的PHP版本页面,我得到502 Bad Gateway。我试图修复它的是什么?相当多的事情,包括相关问题的答案 - nginx 502 bad gateway

这是我使用Ubuntu的默认配置

server {
listen 80;
#   listen [::]:81 ipv6only=on default_server;

root /var/www/html;
index index.php index.html index.htm;

server_name localhost;

location ~* \.(js|css|png|jpg|jpeg|gif|ico|html)$ {
        expires max;
}


location / {
    try_files $uri $uri.php $uri.php/$args /index.php?q=$uri&$args $uri/ =404;
    index index.php index.html index.htm;
    rewrite ^(.*)$ /$1.php;
}

location /phpmyadmin {
  index index.php;
    try_files $uri $uri/ =404;
    auth_basic "Admin Login";
    auth_basic_user_file /etc/nginx/pma_pass;
}

error_page 404 /404.html;

error_page 500 502 503 504 /50x.html;
location = /50x.html {
    root /usr/share/nginx/html;
}

location ~ \.php$ {
    try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
}


location ~ /\.ht {
    deny all;
}
}

编辑: 以下是我认为日志的相关部分

2017/08/11 13:18:13 [error] 27759#0: *270 connect() failed (111: Connection refused) while connecting to upstream, client: 66.61.18.112, server: domain.com, request: "GET /favicon.ico HTTP/1.1", upstream: "http://127.0.0.1:8080/favicon.ico", host: "[IP ADDRESS]", referrer: "http://[IP ADDRESS]/phpmyadmin/index.php"

这是我运行ps aux | grep php-fpm时的结果:

这是我的php-fpm.conf

中没有注释的内容
[global]
; Pid file
; Note: the default prefix is /var
; Default Value: none
pid = /var/run/php5-fpm.pid

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; in a local file.
; Note: the default prefix is /var
; Default Value: log/php-fpm.log
error_log = /var/log/php5-fpm.log


;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;

; To configure the pools it is recommended to have one .conf file per
; pool in the following directory:
include=/etc/php5/fpm/pool.d/*.conf

以下是我在www.conf中没有注释的内容:

listen = 127.0.0.1:9000
listen.owner = www-data  
listen.group = www-data
listen.mode = 0660
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /

我尝试转到index.php后的nginx日志:

[error] 29393#0: *23 connect() failed (111: Connection refused) while connecting to upstream, client: [Computer IP Address], server: [Subdomain.domain.com], request: "GET /favicon.ico HTTP/1.1", upstream:"http://127.0.0.1:8080/favicon.ico", host: [Server IP], referrer: "http://[Server IP]/index.php"

3 个答案:

答案 0 :(得分:4)

所以我检查了我的nginx配置并找到了这些行:

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

然后我转到/etc/nginx/conf.d/*.conf并在servers.conf文件中看到,我计划使用的子域有一个配置但已经不再使用了,所以我将其删除了。这是问题的一个重要部分,因为nginx首先查看此配置,这就是错误包含此子域的原因。

至于php问题,我将配置切换到fastcgi_pass unix:/run/php/php7.0-fpm.sock;,这似乎解决了问题。

答案 1 :(得分:2)

尝试替换

fastcgi_pass unix:/var/run/php5-fpm.sock;

在你的nginx配置中

fastcgi_pass 127.0.0.1:9000;

因为如果您的PHP-FPM配置使用TCP而不是套接字(没关系)。

答案 2 :(得分:2)

你必须改变这一行

从:

listen = 127.0.0.1:9000

为:

listen = /var/run/php5-fpm.sock

在您的www.conf文件中

别忘了重启php。

<强>解释

如果你看一下你的nginx虚拟主机fastcgi_pass参数

location ~ \.php$ {
    try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
}

你会看到你正在将php文件的处理指向php5-fpm socket,但在你的www.conf文件中php是监听端口9000,这就是为什么你应该把它改成/var/run/php5-fpm.sock
