查看nginx error日志

[root@VM_58_118_centos xxx.net]# cat  /data/nginx/vhosts/xxx.net.conf |grep error_log
        #error_log
        error_log /data/nginx/logs/xxx.net.error.access.log error;

[root@VM_58_118_centos xxx.net]# tail -f /data/nginx/logs/xxx.net.error.access.log
[crit] 20462#0: *3436 pwritev() "/var/lib/nginx/tmp/client_body/0000000002

修改nginx.conf

[root@VM_58_118_centos xxx.net]# vim /etc/nginx/nginx.conf
http {
    client_max_body_size 2048m;
    client_body_buffer_size 2m;
    client_body_temp_path /data/www/upload_temp;            #默認/var/lib/nginx/tmp/client_body
    client_header_buffer_size 10m;
    large_client_header_buffers 4 10m;
    
    ......
}

優化nginx proxy參數

[root@VM_58_118_centos xxx.net]# vim /etc/nginx/proxy.conf
proxy_redirect off;
proxy_set_header   X-Forwarded-proto $scheme;
proxy_set_header   Host             $host;
proxy_set_header   X-Real-IP        $remote_addr;
proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
proxy_max_temp_file_size 0;
proxy_connect_timeout      600;
proxy_send_timeout         1800;
proxy_read_timeout         1800;
proxy_buffer_size          512k;
proxy_buffers              4 512k;
proxy_busy_buffers_size    512k;
proxy_temp_file_write_size 512k;

fastcgi相關參數

[root@VM_58_118_centos xxx.net]# vim /etc/nginx/nginx.conf
http {
    #fastcgi_connect_timeout 300;
    #fastcgi_send_timeout 300;
    #fastcgi_read_timeout 300;
    #fastcgi_buffer_size 64k;
    #fastcgi_buffers 4 64k;
}

重啟nginx服務

[root@VM_58_118_centos vhosts]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

[root@VM_58_118_centos xxx.net]# systemctl restart nginx
