LNMP 1.6 常见的502问题解决

在nginx上跑discuz，先修改配置文件

cd /usr/local/nginx/conf/vhosts/

vim test.conf

server
{
    listen ;
    server_name www.test.com;
    index index.html index.htm index.php;
    root /data/www;

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/www.sock;
        #fastcgi_pass 127.0.0.1:;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/www$fastcgi_script_name;
    }
}

 /usr/local/nginx/sbin/nginx -t

/etc/init.d/nginx reload

在浏览器输入 www.test.com 错误502

查看nginx的错误日志，错误日志的位置在主配置文件里面

vim ../nginx.conf

搜索 /error  error_log /usr/local/nginx/logs/nginx_error.log crit; 级别是crit

查看错误日志

cat  /usr/local/nginx/logs/nginx_error.log

 ll /tmp/www.sock

srw-rw---- 1 root root 0 12月 31 01:23 /tmp/www.sock   因为作为其他人，没有读的权限，所以502

vim /usr/local/php/etc/php-fpm.conf　

[www]
listen = /tmp/www.sock
user = php-fpm
group = php-fpm
改为
[www]
listen = /tmp/www.sock
user = php-fpm
group = php-fpm
listen.owner = nobody
listen.group = nobody

/usr/local/php/sbin/php-fpm -t

/etc/init.d/php-fpm restart

刷新 没有问题
