Docker學習 - nginx配置

1.不挂載volumn的方式啓動image

docker run -d -p 80:80 --name nginx-test nginx

2.拷貝文件完後停止container docker cp nginx-test:/etc/nginx/.

/usr/local/docker/nginx/conf

docker stop nginx-test

docker rm nginx-test

目錄結構如下

[centos@centos7 ~]$ tree /usr/local/docker
/usr/local/docker
└── nginx
├── conf
│   ├── conf.d
│   │   └── default.conf
│   ├── fastcgi_params
│   ├── mime.types
│   ├── nginx.conf
│   ├── scgi_params
│   └── uwsgi_params
├── html
│   └── index.html
└── logs
├── access.log
└── error.log

3.挂載本地目錄啓動container

docker run -it -p 80:80 -v /usr/local/docker/nginx/conf:/etc/nginx \

-v /usr/local/docker/nginx/html:/usr/share/nginx/html \

-v /usr/local/docker/nginx/logs:/var/log/nginx \

--privileged=true --name mynginx nginx

 

 

nginx.conf (不變)

?

user  nginx; worker_processes  auto;   error_log  /var/log/nginx/error.log notice; 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" $upstream_addr $upstream_response_time $request_time ';       access_log  /var/log/nginx/access.log  main;       sendfile        on;     #tcp_nopush     on;       keepalive_timeout  65;       #gzip  on;       include /etc/nginx/conf.d/*.conf; }

　

default.conf

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

server {     listen       80;     listen  [::]:80;     server_name  localhost;       #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;     }           location /apptst/ {         proxy_pass  http://192.168.0.109:8080/;         proxy_set_header  Host              $http_host;   # required for docker client's sake         proxy_set_header  X-Real-IP         $remote_addr; # pass on real client's IP         proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;         proxy_set_header  X-Forwarded-Proto $scheme;     } }

　　

4.改動了/usr/local/docker/nginx/conf/conf.d/default.conf后，要重啓container才生效

docker stop mynginx

docker start mynginx

測試

curl http://192.168.0.109/apptst/health-status

 

5.將app啓動在兩個端口上做負載均衡

default.conf

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

upstream apptst_server{   server 192.168.0.109:8080 weight=1;   server 192.168.0.109:8081 weight=1; }     server {     listen       80;     listen  [::]:80;     server_name  localhost;       #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;     }           location /apptst/ {         proxy_set_header  Host              $http_host;   # required for docker client's sake         proxy_set_header  X-Real-IP         $remote_addr; # pass on real client's IP         proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;         proxy_set_header  X-Forwarded-Proto $scheme;        # proxy_pass http://192.168.0.109:8080/;         proxy_pass http://apptst_server/;     }         }

　

測試

curl http://192.168.0.109/apptst/health-status

=》

curl http://192.168.0.109:8080/health-status

curl http://192.168.0.109:8081/health-status

查看/usr/local/docker/nginx/logs/access.log

　

6.利用docker compose把nginx和兩個dotnet應用綁定在一起啓動

 

[centos@centos7 ~]$ cd /usr/app

[centos@centos7 app]$ docker-compose up -d

 

docker-compose.yml

?
