访问docker中的nginx容器部署
1搜索nginx镜像
docker search nginx2拉取nginx镜像
docker pull nginx3创建容器，设置端口映射、目录映射
# 在/root目录下创建nginx目录用于存储nginx数据信息
mkdir ~/nginx
cd ~/nginx
mkdir conf
cd conf
# 在~/nginx/conf/下创建nginx.conf文件,粘贴下面内容
vim nginx.confuser 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;
}
docker run -id --name=c_nginx \
-p 80:80 \
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf \
-v $PWD/logs:/var/log/nginx \
-v $PWD/html:/usr/share/nginx/html \
nginx参数说明：
-p 80:80：将容器的 80端口映射到宿主机的 80 端口。容器就相当于一个小的linux，外网想访问容器的步骤，先是访问阿里云的安全组（如果用的是阿里云服务器的话），看是否放行了80端口，然后访问linux的防火墙，看是否放行80，然后再访问mysql容器，看是否放行80。所以这里要映射一下，映射就是把它暴露了，下面的nginx啥的都一样就不再说了。
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf：将主机当前目录下的 /conf/nginx.conf 挂载到容器的 :/etc/nginx/nginx.conf。配置目录
-v $PWD/logs:/var/log/nginx：将主机当前目录下的 logs 目录挂载到容器的/var/log/nginx。日志目录。
二 进行反向代理的操作
docker ps查询出你的nginx容器的id号，结果如下：
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3929aa630523 nginx "/docker-entrypoint.…" 2 hours ago Up 2 hours 0.0.0.0:80->80/tcp, :::80->80/tcp c_nginx
cf152c11389b redis "docker-entrypoint.s…" 2 weeks ago Up 2 weeks 0.0.0.0:6379->6379/tcp, :::6379->6379/tcp c_redis
e24660ccf0b8 mysql:5.6 "docker-entrypoint.s…" 2 weeks ago Up 2 weeks 0.0.0.0:3306->3306/tcp, :::3306->3306/tcp c_mysql
复制nginx的Id。
docker exec -it 3929aa630523 bash以交互式进入容器
root@3929aa630523:/# which nginx
/usr/sbin/nginx
查找nginx位置，因为-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf \ 挂载到了/etc/nginx/nginx.conf
cd /etc/nginx/
root@3929aa630523:/etc/nginx# ls
conf.d koi-utf mime.types nginx.conf uwsgi_params
fastcgi_params koi-win modules scgi_params win-utf
root@3929aa630523:/etc/nginx# cat nginx.conf
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$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;
}
include /etc/nginx/conf.d/*.conf;就是配置了一个子配置文件在这个地址
root@3929aa630523:/etc/nginx# cd conf.d/
root@3929aa630523:/etc/nginx/conf.d# ls
default.conf
root@3929aa630523:/etc/nginx/conf.d# cat default.conf
server {
listen 80;
listen [::]:80;
server_name localhost;
#charset koi8-r;
#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;
}
# 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 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;
#}
}
在这里改就行了。
但是在想要使用vim时，会出现
root@3929aa630523:/etc/nginx/conf.d# vim default.conf
bash: vim: command not found
这时候就需要安装vim。
可是当你敲apt-get install vim命令时，提示：
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package vim
这时候需要敲：apt-get update，这个命令的作用是：同步 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中列出的源的索引，这样才能获取到最新的软件包。
root@3929aa630523:/etc/nginx/conf.d# apt-get update
Get:1 http://security.debian.org/debian-security buster/updates InRelease [65.4 kB]

Get:6 http://deb.debian.org/debian buster-updates/main amd64 Packages [10.9 kB]
Fetched 8441 kB in 4min 51s (29.0 kB/s)

等更新完毕以后再敲命令：apt-get install vim命令即可。
