502 Bad Gateway
nginx/1.2.9
在百度上查找错误信息:nginx+PHP 错误502 bad gateway时,也没有找到好的方法,这时我分析我的nginx日志文件,我的nginx日志文件存放在/usr/local/nginx/logs/nginx_error.log,发现有如下一行的错误:2016/02/22 15:12:26 [crit] 2967#0: *9 connect() to unix:/tmp/php-fcgi.sock failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /2.php HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-fcgi.sock:", host: "localhost"特别是:connect() to unix:/tmp/php-fcgi.sock failed (13: Permission denied) while connecting to upstream出错,然后我检查我的nginx的sock文件的权限:
ll /tmp
total 4
srwxrwxrwx 1 MySQL mysql 0 Feb 22 00:58 mysql.sock
drwxr-xr-x 3 root root 4096 Feb 16 13:59 pear
srw-rw---- 1 root root 0 Feb 22 00:58 php-fcgi.sock
修改后的权限
[root@centos3 nginx]# chmod 777 /tmp/php-fcgi.sock
[root@centos3 nginx]# ll /tmp
total 4
srwxrwxrwx 1 mysql mysql 0 Feb 22 00:58 mysql.sock
drwxr-xr-x 3 root root 4096 Feb 16 13:59 pear
srwxrwxrwx 1 root root 0 Feb 22 00:58 php-fcgi.sock
显示的结果:
curl localhost/2.php
This is a test
[root@centos3 nginx]#
这时nginx的502错误已解决了;
