docker安装Nginx挂载外部配置文件

一、拉取nginx镜像

docker pull nginx

二、在宿主机中创建挂载目录

mkdir -p /data/nginx/{conf,conf.d,html,log}

三、将配置文件放到挂载目录

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

        ##
        # Basic Settings
        ##

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;
        

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        ##
        # SSL Settings
        ##

        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
        ssl_prefer_server_ciphers on;

        ##
        # Logging Settings
        ##

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        ##
        # Gzip Settings
        ##

        gzip on;
        gzip_disable "msie6";

        # gzip_vary on;
        # gzip_proxied any;
        # gzip_comp_level 6;
        # gzip_buffers 16 8k;
        # gzip_http_version 1.1;
        # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

        ##
        # Virtual Host Configs
        ##

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;

        server{
                listen 80;
                server_name your_server_name;   #你的serverName
                root /usr/share/nginx/html;
                index index.html;
        }

}

只要启动访问80端口就能直接访问到/usr/share/nginx/html/index.html了

四、启动nginx容器

docker run --name my_nginx -d -p 80:80  -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/log:/var/log/nginx -v /data/nginx/html:/usr/share/nginx/html nginx

第一个-v:挂载nginx的主配置文件,以方便在宿主机上直接修改容器的配置文件

第二个-v:挂载容器内nginx的日志,容器运行起来之后,可以直接在宿主机的这个目录中查看nginx日志

第三个-v:挂载静态页面目录

五、修改宿主机挂载目录中的配置文件以重启nginx容器

把server模块中的index改成其他的页面,以证明可以在宿主机中修改配置文件

server{
    listen 80;
    server_name your_server_name; #你的serverName
    root /usr/share/nginx/html;
    index main.html;
}

然后重启nginx容器:docker restart containerID

停止命令 docker stop my_nginx

之后刷新页面你会发现页面从index.html变成了main.html
