Docker 安装 nginx

  1. 创建将要挂载的目录(将自己的配置文件挂载docker安装的nginx默认配置)
mkdir -p /usr/nginx/{conf,conf.d,html,logs}
  1. 先要有配置文件才能启动容器,创建配置文件(不用修改默认目录,下面会挂载,初始文件就行)
vim /usr/nginx/conf/nginx.conf
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;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}
vim /usr/nginx/conf.d/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;
    #}
}
  1. 为了方便测试,创建一个test.html文件
vi /usr/nginx/html/test.html
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>请求成功!</h1>
</body>
</html>
  1. 启动容器(没下载镜像会自动下载)
docker run --name nginx -d -p 80:80 -v /usr/nginx/html:/usr/share/nginx/html:ro -v /usr/nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro  -v /usr/nginx/conf.d:/etc/nginx/conf.d:ro -v /usr/nginx/logs:/var/log/nginx nginx

第一个-v后是将本地的这个存放静态资源的目录挂载到nginx的默认加载目录
第二个-v后是将本地的nginx.conf配置文件挂载nginx的默认配置文件
第三个-v后是将nginx的默认日志文件与自定义的这个目录可以读写
第四个-v后是将本地的conf.d配置文件夹挂载nginx的默认配置文件夹,里面有default.conf配置文件,负载均衡和反向代理也在这里配置
ro表示只能读,rw是读写,不设置rw=true,可以使用docker inspect nginx查看
挂载之后可以使用docker exec -it nginx bash进入容器查看是否已挂载,例如,进入/usr/share/nginx/html查看里面是否有主机/usr/nginx/html里面的文件
