        • default.conf
      • start_nginx.sh

1. 基于运维统一脚本中，3、常见服务部署下的中间件服务选选中的web网站 Nginx
2. 使用docker环境安装

1. 该脚本为了在Centos7服务器中docker环境上部署nginx服务
2. 采用https://hub.docker.com/上的官方镜像，可以用自行构建的镜像
3. nginx的配置文件外置挂载出，可根据情况进行不同的配置(正反向带，负载均衡等)
4. 当前准备的配置文件为最简单的一种，需要根据不同的应用场景来修改不同的配置，且网站目录页外置出来，默认配置只支持html
5. 其他语言的支持可根据实际情况进行配置后使用

1. 后文中提到的nginx配置需要存放在如下路径下

template/
├── nginx
    ├── default.conf
    └── nginx.conf
start_nginx.sh

2. 如果路径需要修改路径，则自行修改template的变量

bashpath="$(cd `dirname $0`;pwd)"
 nginx_port="8083"
 nginx_name="nginx1.21"
 nginx_images_tag="nginx:1.21-perl"
 nginx_conf_dir="/opt/nginx/conf"
 nginx_html="/opt/nginx/html"
 nginx_conf="nginx.conf"
 log_dir="${bashpath}/log/middle"
 template="${bashpath}/template/nginx"

sh start_nginx.sh

如图所示，设置默认值，可根据实际情况填写不同的值即可

cd template/nginx

user  nginx;
worker_processes  auto;

pid        /var/run/nginx.pid;
