Docker安装docker-Compose并配置nginx

1 安装

目前有两种主流安装方式，笔者使用了第一种方式。

第一种
下载最新的docker-compose文件

下载完成后需要对/usr/local/bin/docker-compose目录进行赋权

1	curl -L https://github.com/docker/compose/releases/download/1.8.0/run.sh > /usr/local/bin/docker-compose

1	chmod +x /usr/local/bin/docker-compose

测试结果

[root@localhost bin]# docker-compose --version

卸载

1	rm /usr/local/bin/docker-compose

2 docker-compose 配置挂载 Volume 并运行 nginx

1.先在宿主机创建挂载目录：

1	mkdir -p /data/nginx2/{conf,conf.d,html,logs}

2.然后把nginx的配置文件 nginx.conf 文件放到 /data/nginx2/conf/

nginx.conf配置文件如下

# nginx.conf配置文件如下
user  nginx;
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;
}

3.将使用的nginx子配置，配置文件 default.conf 放到 /data/nginx2/conf.d/

default.conf 配置文件如下

# default.conf 配置文件如下 
server {
    listen       80;
    server_name  localhost;
 
    # rewrite ^(.*)$  https://www.vhxsl.com permanent;
 
    location / {
      root   /usr/share/nginx/html;
      index  index.html index.htm;
    }
 
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

4.docker-compose 的配置nginx 的启动文件conpose-nginx.yml 放到/data/nginx2/

docker-compose.yml 配置文件如下

#docker-compose.yml 配置文件如下 
version: "3"
services:
   composeNginx:
     image: nginx
     ports:
       - "8085:80"
     volumes:
       - /data/nginx2/html:/usr/share/nginx/html
       - /data/nginx2/conf/nginx.conf:/etc/nginx/nginx.conf
       - /data/nginx2/conf.d:/etc/nginx/conf.d
       - /data/nginx2/logs:/var/log/nginx
     restart: always
     container_name: composeNginx

5.将一个 index.html 放到 /data/nginx2/html

index.html随便写都可以

aaaaaa

6.使用docker-compose 启动nginx

因为我们的yml文件不是docker-compose.yml，在进行服务排编是需要指定yml文件名称

1	docker-compose -f conpose-nginx.yml up -d

效果如下

[wjk@localhost nginx2]# docker-compose -f conpose-nginx.yml up -d
Creating network "root_default" with the default driver

[wjk@localhost nginx2]# docker ps

在外部浏览器可以访问 http://ip:8085/

[root@localhost nginx]# docker-compose -f conpose-nginx.yml up -d
ERROR: Version in "./conpose-nginx.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

linux 版本过于旧了，需要在docker-compose.yml，修改verison值，之前是3.5，现改成2.0即可
