docker之安装nginx

约定不等于承诺〃 2022-12-10 08:48 38阅读 0赞

#### 一.拉取镜像 ####

docker pull nginx

#### 二.创建挂载映射目录 ####

##### 1.创建nginx配置目录 #####

mkdir -p /opt/docker-nginx/conf

##### 2.创建nginx的日志文件目录 #####

mkdir -p /opt/docker-nginx/logs

##### 3.创建nginx的html #####

mkdir -p /opt/docker-nginx/html

#### 三.配置启动参数启动容器 ####

##### 1.配置实例并启动 #####

docker  run -p 80:80  --name nginx -v /opt/docker-nginx/html:/usr/share/nginx/html -v /docker-nginx/nginx/logs:/var/log/nginx   -d nginx

##### 2.复制docker内nginx配置文件目录到本地配置文件目录，以便修改 #####

本地nginx配置文件目录是 /opt/docker-nginx/conf/

docker内部nginx的配置文件目录是 /etc/nginx

复制docker内配置文件目录到本地路径

docker container cp nginx:/etc/nginx/ /opt/docker-nginx/conf/

##### 3.删除容器，重新配置实例运行 #####

(1)停止nginx容器

docker stop nginx

(2)删除nginx容器

nginx rm nginx

(3)配置实例运行

docker  run -p 80:80 --restart=always --name nginx -v /opt/docker-nginx/html:/usr/share/nginx/html -v /opt/docker-nginx/logs:/var/log/nginx -v /opt/docker-nginx/conf/nginx/conf.d:/etc/nginx/conf.d  -d nginx

参数说明：

*  \-p 80:80 端口映射到本地端口
 *  –name nginx 容器别名
 *  \-v 配置目录挂载映射
 *  \-d nginx 后他启动

#### 四.反向代理 ####

目的：将部署的springboot项目mall通过nginx进行反向代理或者负载均衡

##### 1.重新配置nginx容器参数启动 #####

docker  run -p 80:80 --restart=always --name nginx --link mall:mall -v  /opt/docker-nginx/html:/usr/share/nginx/html -v /opt/docker-nginx/logs:/var/log/nginx -v /opt/docker-nginx/conf/nginx/conf.d:/etc/nginx/conf.d  -d nginx

在前面的启动参数加了

*  –link mall:mall 将容器外的mall容器通过别名mall映射到该容器中

##### 2.增加mall.conf配置文件 #####

[root@localhost conf.d]# vim mall.conf
    server {
        listen  80;
        server_name localhost;
        access_log /var/log/nginx/mall.access.log main;
        error_log /var/log/nginx/mall.error.log error;
        location / {
            proxy_set_header  Host  $http_host;
            proxy_set_header  X-Real-IP  $remote_addr;
            proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_pass  http://mall;
        }
    }
     upstream mall{
         server mall:8080;
        }

##### 3.重新启动nginx #####

重新启动

> docker restart nginx

访问宿主机 192.168.102.129

> 访问则跳转到 mall:8080

#### 五.问题解决 ####

##### 1.端口反向代理配置，后启动访问，报错 #####

*2 connect() failed (113: No route to host) while connecting to upstream, client: 192.168.102.1, server: 192.168.102.129, request: "GET / HTTP/1.1", upstream: "http://192.168.102.129:8080/", host: "192.168.102.129"

解决：

##### 2.访问不了主页 #####

问题如下：

directory index of "/usr/share/nginx/html/" is forbidden, client: 192.168.102.1, server: localhost, request: "GET / HTTP/1.1", host: "192.168.102.129"

本例中因为宿主机里面/opt/docker-nginx/html下面的index文件,修改为index.html 重启即可
