1.Dockerfile文件
# This my first nginx Dockerfile
# Version 1.0
# Base images 基础镜像
FROM centos:centos7
#MAINTAINER 维护者信息
MAINTAINER fendo 2312892206@qq.com
#ADD 获取url中的文件,放在当前目录下
ADD http://nginx.org/download/nginx-1.14.0.tar.gz .
#RUN 执行以下命令
RUN yum install -y pcre-devel wget net-tools gcc zlib zlib-devel make openssl-devel
RUN useradd -M -s /sbin/nologin nginx
RUN tar -zxvf nginx-1.14.0.tar.gz
RUN mkdir -p /usr/local/nginx
RUN cd nginx-1.14.0 && ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module && make && make install
RUN ln -s /usr/local/nginx/sbin/* /usr/local/sbin/
#EXPOSE 映射端口
EXPOSE 80
#CMD 运行以下命令
CMD ["nginx"]
2、执行构建镜像命令
[root@swarm01 docker]# docker build --rm --tag centos_nginx:centos7 .
3、查看镜像是否安装构建成功
[root@swarm01 docker]# docker images
4、启动容器
可以通过以下两种方式启动容器:
不挂载文件:
docker run -i -t -d -p 192.168.182.110:80:80 centos_nginx /bin/bash
挂载文件:
docker run \
--name centos_nginx \
-d -p 80:80 \
-v /home/nginx/html:/usr/share/nginx/html \
-v /home/nginx/log:/var/log/nginx \
-v /home/nginx/nginx.conf:/usr/local/nginx/nginx.conf:ro \
-v /home/nginx/conf.d:/usr/local/nginx/conf.d \
nginx
注意:
(1)第一个"-v",是项目位置,把项目放到挂载到的目录下即可;
(2)第二个"-v",是挂载的主配置文件"nginx.conf",注意"nginx.conf"文件内有一行"include /etc/nginx/conf.d/*.conf;",这个include指向了子配置文件的路径,此处注意include后所跟的路径一定不要出错。
(3)第三个"-v",把docker内子配置文件的路径也挂载了出来,注意要与(2)中include指向路径一致
(4)重点强调一下,nginx.conf是挂载了一个文件(docker是不推荐这样用的),conf.d挂载的是一个目录
启动成功之后如下:
5.在系统中创建Nginx配置文件
通过上面的命令启动之后,会在/home/nginx目录下多出以下文件
这些文件就是与Docker容器共享的配置文件,在nginx.conf目录下创建Nginx配置文件nginx.conf,内容如下:
user root;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
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;
keepalive_timeout 65;
autoindex on;
#gzip on;
include /etc/nginx/conf.d/*.conf;
client_max_body_size 100M;
client_header_buffer_size 128k;
large_client_header_buffers 4 128k;
}
然后在conf.d目录下创建default.conf文件,内容如下:
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log /var/log/nginx/log/host.access.log main;
location / {
root /home/nginx/html/fendo;
index index.html index.htm;
autoindex on;
try_files $uri /index/index/page.html;
#try_files $uri /index/map/page.html;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# 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;
#}
}
然后在/home/nginx/fendo目录下创建Index.html文件,内容为:
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx! This is a demo!</title>
<style>
body {
width: 35em;
margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>
<h1>*********************************** Welcome to nginx! Fendo ***********************************</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

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>
修改好之后,重启下Nginx
[root@swarm01 conf.d]# docker restart centos_nginx
centos_nginx
6.测试Nginx
访问http://192.168.182.110/fendo/效果如下:
7.一些错误
7.1、访问 curl http://192.168.182.110/fendo/出现拒绝连接,解决方法就是进入容器 docker exec -i -t centos_nginx /bin/sh接着在容器里面执行(直接输入即可)nginx 启动Nginx。
7.2、如过挂载Nginx文件时报错,基本就是路径的问题。
unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type
