线上Nginx镜像构建及容器使用

1.Dockerfile-nginx文件内容:

FROM CentOS:latest

RUN yum -y install gcc gcc-c++ make \

openssl-devel pcre-devel gd-devel \

libxml2-devel libxslt-devel zlib-devel \

gd-devel perl-ExtUtils-Embed \

iproute net-tools telnet wget curl && \

yum clean all && \

useradd -s /sbin/nologin -M nginx && \

mkdir -p /var/tmp/nginx && \

rm -rf /var/cache/yum/

RUN wget http://nginx.org/download/nginx-1.15.9.tar.gz &&\

tar -zxvf nginx-1.15.9.tar.gz && \

cd nginx-1.15.9 && \

./configure --prefix=/usr/local/nginx --sbin-path=/usr/local/nginx/sbin/nginx \

make -j 4 && make install && \

cd / && rm -rf nginx-1.15.9 && \

ls -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

ENV PATH $PATH:/usr/local/nginx/sbin

WORKDIR /usr/local/nginx

EXPOSE 80

CMD ["nginx", "-g","daemon off;"]

2.构建镜像命令:

docker build -t nginx:v2 -f Dockerfile-nginx .

-t:代表 tag -f:指定dockerfile文件 .用当前目录的环境变量

3.从本地镜像仓库下载nginx镜像

docker pull xx.xx.xx.xx/library/nginx:v2

4,在要安装nginx的服务器创建目录

4.1 配置文件目录:mkdir -p /opt/nginx/conf/vhost

/opt/nginx/conf下有两个:一个为nginx.conf,设置nginx标准配置(随着业务可能需优化);标准配置文件详见nginx.conf

参考:

server_tokens off;

user nginx;

worker_processes 4;

worker_rlimit_nofile 65535;

error_log /var/log/nginx/error.log;

events

{

use epoll;

worker_connections 10240;

}

http{

log_format  main  '$remote_addr $remote_user [$time_local] "$request" '

              '$status $body_bytes_sent "$http_referer" '

              '$http_user_agent $http_x_forwarded_for $request_time $upstream_response_time $upstream_addr $upstream_status';

access_log  /var/log/nginx/access.log  main;               

include      mime.types;

default_type application/octet-stream;

server_names_hash_bucket_size 128;

client_header_buffer_size 32k;

large_client_header_buffers 4 32k;

client_max_body_size 8m;       

sendfile on;

tcp_nopush    on;     

keepalive_timeout 60;

send_timeout 15;

tcp_nodelay on;

fastcgi_connect_timeout 300;

fastcgi_send_timeout 300;

fastcgi_read_timeout 300;

fastcgi_buffer_size 64k;

fastcgi_buffers 4 64k;

fastcgi_busy_buffers_size 128k;

fastcgi_temp_file_write_size 128k;

gzip on;

gzip_min_length 1k;

gzip_buffers    4 32k;

gzip_http_version 1.1;

gzip_comp_level 2;

gzip_types      text/plain application/x-Javascript text/css application/xml;

gzip_vary on;

include /usr/local/nginx/conf/vhost/*.conf;

}

> 另一个为vhost,vhost配置不同的域名解析文件(就是真正的业务配置)

>  vhost下的文件统一命名格式:域名.conf

参考:

upstream gw_ma {

server xx.xx.xx.xx:5601;

}

server {

listen 80;

server_name www.nan.com;

access_log /usr/local/nginx/logs/www.nan.com.log;

error_log /usr/local/nginx/logs/www.nan.com.err;

listen  443 ssl;

ssl_buffer_size 4k;

ssl_certificate  /usr/local/nginx/cert/1_gw.nan_bundle.crt;  #在docker启动镜像的时候挂载证书目录; /opt/nginx/vert

ssl_certificate_key /usr/local/nginx/cert/2_gw.nan.com.cn.key;

ssl_session_timeout 5m;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;

ssl_prefer_server_ciphers on;

location / {

proxy_set_header X-Forwarded-Host $host;

proxy_set_header X-Forwarded-Server $host;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_pass http://gw_ma;

}

}

4.2 日志文件目录:mdkir -p /opt/nginx/logs

5.启动容器

参考:docker run -d --name=nginx02 -p 9999:80 -v /opt/nginx/conf/nginx.conf:/usr/local/nginx/conf/nginx.conf -v /opt/nginx/conf/vhost/:/usr/local/nginx/conf/vhost/ -v /opt/nginx/logs/:/usr/local/nginx/logs/ xx.xx.xx.xx/library/nginx:v2
