内部服务器错误1.Nginx服务没有运行

[17:10 root@web01 /etc/nginx/conf.d]# curl www.oldboy.com
curl: (7) Failed connect to www.oldboy.com:80; Connection refused
[17:10 root@web01 /etc/nginx/conf.d]# systemctl restart nginx
[17:10 root@web01 /etc/nginx/conf.d]# curl www.oldboy.com
www.oldboy.com

2.查看详细Nginx错误提示 检查语法 nginx -t

systemctl  
[root@web-204 html]# systemctl start nginx
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

[root@web-204 html]# nginx -t
nginx: [emerg] unexpected "}" in /etc/nginx/nginx.conf:49
nginx: configuration file /etc/nginx/nginx.conf test failed

3./etc/hosts文件域名没有解析

[root@web01 /etc/nginx]# curl blog.oldboy.com
<a href="https://www.afternic.com/forsale/blog.oldboy.com?utm_source=TDFS_DASLNC&amp;utm_medium=DASLNC&amp;utm_campaign=TDFS_DASLNC&amp;traffic_type=TDFS_DASLNC&amp;traffic_id=daslnc&amp;">Found</a>.

4.server_name这行没有以分号结尾 ";"

 40     server   {
 41         listen       80;
 42         server_name  blog.oldboy.com   \\没有以 ; 结尾
 43         location / {
 44         root   /usr/share/nginx/html/blog;
 45         index  index.html index.htm;
 46         }
 47     }
 48 
 49 }

5.报错—404 找不到

[root@web01 ~]# cat /usr/share/nginx/html/{www,blog}/index.html
www.oldboy.com
blog.oldboy.com
[root@web01 ~]# curl blog.oldboy.com
<html>
<head><title>404 Not Found</title></head>
<body>
<center><h1>404 Not Found</h1></center>

* * *

<center>nginx/1.16.0</center>
</body>
</html

6.报错—403 权限拒绝(第一种)

模拟错误:站点目录权限修改为000 测试完后改回644:

[09:34 root@web01 ~]# ll  /usr/share/nginx/html/www/
total 4
-rw-r--r-- 1 root root 15 Jun  5 09:00 index.html
[09:35 root@web01 ~]# chmod 600 index.html
[09:35 root@web01 ~]#  ls -l index.html 
-rw------- 1 root root 15 Jun  5 09:00 index.html
[09:35 root@web01 ~]# curl www.oldboy.com
<html>
<head><title>403 Forbidden</title></head>
<body>
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx/1.16.0</center>
</body>
</html>

7.报错—403 首页文件不存在(第二种)

模拟将站点目录移动到别处:

[16:35 root@web01 ~]# mv /usr/share/nginx/html/www/index.html /tmp/
[16:35 root@web01 ~]# curl www.oldboy.com
<html>
<head><title>403 Forbidden</title></head>
<body>
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx/1.16.0</center>
</body>
</html>

8. Cannot assign requested address 无法分配指定请求的ip地址

[root@web01 /etc/nginx]# nginx -t 
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: [emerg] bind() to 10.0.0.9:80 failed (99: Cannot assign requested address)
nginx: configuration file /etc/nginx/nginx.conf test failed

解决方法1:添加1个ip地址:

[root@web01 ~]# ip addr add 10.0.0.9/24 dev eth0 label eth0:1   \\添加此ip

9. 304 Not Modified 用户读取浏览器缓存

10.Address already in use 地址已被使用

11.Connection refused 连接拒绝

[16:25 root@web01 ~]# curl www.oldboy.com
curl: (7) Failed connect to www.oldboy.com:80; Connection refused
[16:25 root@web01 ~]# systemctl restart nginx
[16:25 root@web01 ~]# curl www.oldboy.com
www.oldboy.com

12. conflicting server name 服务器名称冲突

 [root 12:27:22 @web01 conf.d]# vim 01-www.conf

      listen    80;
      server_name     www.oldboy.com;  \\域名重复

     }

[root 12:35:02 @web01 conf.d]# cat default.conf
server {
    listen       80;
    server_name  www.oldboy.com;   \\域名重复
    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
}
[16:52 root@web01 /etc/nginx/conf.d]# gzip  default.conf
[16:52 root@web01 /etc/nginx/conf.d]# ll
total 16
-rw-r--r-- 1 root root 219 Jun  5 12:56 01-www.conf

[root@web01 ~]# ll -d /usr/share/nginx/html/blog/
drwxr-xr-x 5 nginx nginx 4096 Jun  6 21:03 /usr/share/nginx/html/blog/

15.Can't connect to local MySQL server through socket

[root@web01 html]# systemctl restart mariadb.service 

16.Unit is masked nginx服务被删除了

[root@lb02 ~]# tail -1 /etc/sysctl.conf 
net.ipv4.ip_nonlocal_bind = 1
