重启nginx服务 systemctl restart nginx
[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
一般宝花括号说明配置文件内容语法错误了
"}"不成对
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
image
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&utm_medium=DASLNC&utm_campaign=TDFS_DASLNC&traffic_type=TDFS_DASLNC&traffic_id=daslnc&">Found</a>.
image
4.server_name这行没有以分号结尾 ";"
treminated 结束
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 }
image
5.报错—404 找不到
站点目录可能没有创建,或者nginx.conf配置文件站点目录写错了
[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
image
6.报错—403 权限拒绝(第一种)
Forbidden 权限拒绝
image
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)
首页文件不存在 默认是找首页文件
image
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
本地没有10.0.0.9 的ip
10.0.0.9:80 (failedCannot assign)
[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
/var/log/nginx/access.log日志中显示304
image
10.Address already in use 地址已被使用
nginx已经启动了,在使用80端口
image
只是提示,不是报错
Address already in use
nginx正在运行中
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
域名冲突: 有两个或多个 虚拟主机的域名相同了
解决方法:可以将默认 default.conf压缩
[root 12:27:22 @web01 conf.d]# vim 01-www.conf
server {
listen 80;
server_name www.oldboy.com; \\域名重复
#charset koi8-r;
access_log /var/log/nginx/access_www.log main;
location / {
root /usr/share/nginx/html/www;
index index.html index.htm;
}
}
[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
-rw-r--r-- 1 root root 240 Jun 5 12:55 02-blog.conf
-rw-r--r-- 1 root root 488 Apr 23 22:34 default.conf.gz \\压缩
-rw-r--r-- 1 root root 123 Jun 5 12:41 status.conf
13.500 internal Server Error
内部服务器错误
image
设置了权限认证auth_basic_user_file
密码文件权限不对改为600
[09:45 root@web01 /etc/nginx]# chmod 600 htpasswd
[09:46 root@web01 /etc/nginx]# ll htpasswd
-rw------- 1 nginx nginx 45 Jun 6 09:30 htpasswd
14.Error establishing a database connection
建立数据库连接失败
搭建好的wordpress博客进不去
修改权限blog站点目录的属主属组为nginx
[root@web01 ~]# chown -R nginx.nginx /usr/share/nginx/html/blog/
[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/
image
15.Can't connect to local MySQL server through socket
连接不到本地的数据库
