nginx部署docker化

docker compose 模式

首先创建一个名为Nginx的文件夹，然后在里面创建一个html文件夹以及config.d文件夹(这两个分别是网站目录以及nginx配置目录)

mkdir -p /data0/Nginx
cd Nginx
mkdir html
mkdir config.d

创建Dockerfile和docker-compose.yml

touch Dockerfile
touch docker-compose.yml

docker-compose.yml的内容：

version: '3.3' #这个是docker的版本
services:
  blog:
    container_name: blog #容器名称
    build: . #构建目录
    ports: #端口映射 对应 -p
     - "80:80"
     - "443:443"
    volumes: #目录挂载 对应 -v
     - /data0/Nginx/log:/usr/local/openresty/nginx/logs 

Dockerfile的内容：

FROM openresty/openresty 
USER root

EXPOSE 80
EXPOSE 443

RUN rm -rf /etc/nginx/conf.d
RUN rm -rf /usr/local/openresty/nginx/html

COPY ./html /usr/local/openresty/nginx/html
COPY ./config.d /etc/nginx/conf.d

将以上内容复制粘贴到对应文件中。 然后在config.d文件夹中创建一个配置文件

vim config.d/default.conf

文件内容如下：

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    access_log  /usr/local/openresty/nginx/logs/host.access.log;

    location / {
        root   /usr/local/openresty/nginx/html/default;
        index  index.html index.htm;
        try_files $uri $uri/ /index.html; #这里是为了能使vue运行的配置
    }
    #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/local/openresty/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           /usr/local/openresty/nginx/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;
    #}
}

接着在html文件里面创建index.html

mkdir html/default
echo hello > html/default/index.html

最后回到Nginx目录

cd ..

执行运行命令：

docker-compose up -d

若出现：

Creating network "docker_default" with the default driver
Creating blog ... done

即为成功，可访问对应网址进行判断。 如果需要刷新缓存，则运行：

docker-compose build --no-cache

然后再执行运行命令即可。 注意： 重新构建时记得清除之前构建完的镜像和容器。 关闭服务可使用：

docker-compose down

普通模式

首先拉取nginx镜像：

docker pull openresty/openresty

其次创建文件夹：

mkdir -p /opt/config.d
mkdir -p /opt/www
mkdir -p /opt/log

这里的两个文件夹分别是nginx的配置文件夹和网站文件夹 接着启动容器：

docker run -id --name opennginx -p 80:80 openresty/openresty

然后运行以下命令：

docker cp opennginx:/etc/nginx/conf.d/* /opt/config.d

执行完之后会出现一个配置文件，可直接在里面配置或这替换这个文件，默认配置内容如下：

# nginx.vh.default.conf  --  docker-openresty
#
# This file is installed to:
#   `/etc/nginx/conf.d/default.conf`
#
# It tracks the `server` section of the upstream OpenResty's `nginx.conf`.
#
# This config (and any other configs in `etc/nginx/conf.d/`) is loaded by
# default by the `include` directive in `/usr/local/openresty/nginx/conf/nginx.conf`.
#
# See https://github.com/openresty/docker-openresty/blob/master/README.md#nginx-config-files
#


server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    access_log  /usr/local/openresty/nginx/logs/host.access.log;

    location / {
        root   /usr/local/openresty/nginx/html;
        index  index.html index.htm;
        try_files $uri $uri/ /index.html; #这里是为了能使vue运行的配置
    }
    #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/local/openresty/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           /usr/local/openresty/nginx/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;
    #}
}

配置完成之后执行以下命令

docker run -id --name opennginx \
-p 80:80 \
-p 443:433 \
-v /opt/www:/usr/local/openresty/nginx/html \
-v /opt/config.d:/etc/nginx/conf.d \
-v /opt/log:/usr/local/openresty/nginx/logs \
openresty/openresty

打开浏览器访问对应地址出现内容即为成功。 注意： 这个地址/usr/local/openresty/nginx/html是指你在nginx上面配置的root关键字后面的地址，我这里使用的是默认的，日志地址同理。
