【081】使用Nginx的官方Docker镜像,启动容器后无法显示自己网站页面,总显示Nginx官方默认页面的问题的解决方法

问题重现
自己编写一个 index.html 文件。index.html的内容任意,在本文不做过多讨论。在宿主机上创建如下目录结构:
/your/path/front
├─config
│ └─nginx.conf
│
└─projects
└─index.html
其中 nginx.conf 是配置文件。
nginx.conf 内容如下:
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
worker_rlimit_nofile 100000;
events {
worker_connections 2048;
multi_accept on;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
# access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
#gzip on;
include /etc/nginx/conf.d/*.conf;
server_tokens off;
tcp_nopush on;
tcp_nodelay on;
access_log off;
error_log /var/log/nginx/error.log crit;
keepalive_timeout 10;
client_header_timeout 10;
client_body_timeout 10;
reset_timedout_connection on;
send_timeout 10;
limit_conn_zone $binary_remote_addr zone=addr:5m;
limit_conn addr 100;
charset UTF-8;
gzip on;
gzip_disable "msie6";
gzip_proxied any;
gzip_min_length 1000;
gzip_comp_level 6;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
open_file_cache max=100000 inactive=20s;
open_file_cache_valid 30s;
open_file_cache_min_uses 2;
open_file_cache_errors on;
include /etc/nginx/sites-enabled/*;
server {
listen 80;
server_name 50.50.50.50;
location / {
root '/your/path/front/projects/dist';
try_files $uri $uri/ /index.html =404;
}
}
}
创建 nginx 的容器:
docker run --name nginx \
-v /your/path/front/config/nginx.conf:/etc/nginx/nginx.conf:ro \
-v /your/path/front/projects/dist:/your/path/front/projects/dist \
--restart=always \
-p 80:80 -d nginx:1.13
重启docker容器:
docker restart nginx
然后使用 curl 访问 127.0.0.1 效果如下:
# curl 127.0.0.1
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {
width: 35em;
margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>
<p>For online documentation and support please refer to
<a href="http://nginx.org/">nginx.org</a>.<br/>
Commercial support is available at
<a href="http://nginx.com/">nginx.com</a>.</p>
<p><em>Thank you for using nginx.</em></p>
</body>
</html>
也就是说,新上传的 index.html 没有正常返回。返回的是Nginx默认欢迎页。
问题原因
Nginx的docker容器中,有一个默认配置文件 /etc/nginx/nginx.conf 。还有一个默认放配置文件的目录 /etc/nginx/conf.d。nginx 会加载目录conf.d 下的 *.conf 文件。如果这些 .conf 文件的内容和 /etc/nginx/nginx.conf 文件有冲突,那么nginx会默认用 conf.d 目录下的文件配置去覆盖 nginx.conf 文件里面的配置。nginx 容器的 conf.d 目录下有个 default.conf 配置文件。
可以看一下这个文件内容:
default.conf
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
这个文件也是监听80端口。与宿主机上的配置文件有冲突,按照数据卷的配置,就是和容器内的 /etc/nginx/nginx.conf 配置文件有冲突。因此 default.conf 文件的配置会覆盖掉你的网站的配置。解决方法就是删除 default.conf
解决方法
进入正在运行的Nginx docker容器:
docker exec -it nginx bash
删除 /etc/nginx/conf.d/default.conf 文件
cd /etc/nginx/conf.d
rm -rf default.conf
执行 exit
退出容器。在宿主机上执行命令 docker restart nginx
就可以解决此问题了。
