<架构探险之路> Docker搭建微服务自动部署平台，让我们来了解下Docker中如何安装、使用nginx吧！

Docker 之 Nginx环境搭建

Nginx 安装教程

Linux 环境

Linux 中安装

安装编译工具及库文件

yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

首先要安装 PCRE

PCRE 作用是让 Nginx 支持 Rewrite 功能

若提示无wget则安装（在 Docker 拉取的源 centos 中默认是没安装的）

yum -y install wget

进入程序安装目录

cd /usr/local/src/

下载pcre安装包

wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz

解压安装包:
```
tar -zxvf pcre-8.35.tar.gz
```
删除安装包
```
rm -rf pcre-8.35.tar.gz
```
进入安装包
```
cd pcre-8.35
```
编译安装
```
./configure
make && make install
```

查看pcre版本

preconv --version

[root@de790c02f7b6 pcre-8.35]# preconv --version
GNU preconv (groff) version 1.22.2 with iconv support

安装 Nginx

下载安装包

wget http://nginx.org/download/nginx-1.6.2.tar.gz

安装

 cd nginx-1.8.0
 ./configure --prefix=/usr/local/nginx
 make
 make install

检查安装结果
```
  /usr/local/nginx/sbin/nginx -v
```

Dockerfile 安装

脚本

FROM centos:latest
## 制作者信息
MAINTAINER xiachaoyang xiazhaoyang@live.com
RUN yum install -y pcre-devel wget net-tools gcc zlib zlib-devel make openssl-devel
## 创建目录
RUN mkdir -p /usr/local/nginx
## 本地安装 直接自动解压
## ADD nginx-1.8.0.tar.gz /usr/local/src
## 在线安装
RUN cd /usr/local/src
ADD http://nginx.org/download/nginx-1.8.0.tar.gz .
RUN tar -zxvf nginx-1.8.0.tar.gz
RUN ln -s /usr/local/src /componets
RUN cd nginx-1.8.0 && ./configure --prefix=/usr/local/nginx && make && make install
RUN rm -vf /usr/local/nginx/conf/nginx.conf
ADD http://www.apelearn.com/study_v2/.nginx_conf /usr/local/nginx/conf/nginx.conf
EXPOSE 80
# 设置启动时执行命令
#ENTRYPOINT /usr/local/nginx/sbin/nginx -v

镜像

docker build -t env-nginx . docker images docker tag [镜像ID] env-nginx:1.0 docker run -i -t -p 80:80 env-nginx:1.0

清空 Nginx Docker

docker rm -f docker container ls -a -q docker rmi -f env-nginx:2.0 docker build -t env-nginx:2.0 . docker run -i -t -p 8001:80 –name nginx –restart=always env-nginx:2.0

运行后执行nginx

xiazhaoyangdeMacBook-Pro:~ xiazhaoyang$ docker run -i -t -p 8001:80 --restart=always 127.0.0.1:5000/env-nginx:1.0
[root@56dfba762876 /]# cd usr/local/nginx/sbin/
[root@56dfba762876 sbin]# ls
nginx
[root@56dfba762876 sbin]# ./nginx -v    
nginx version: nginx/1.8.0
[root@56dfba762876 sbin]# ps -ef|grep nginx
root        18     1  0 07:44 pts/0    00:00:00 grep --color=auto nginx
[root@56dfba762876 sbin]# ./nginx
[root@56dfba762876 sbin]# ps -ef|grep nginx
root        20     1  0 07:45 ?        00:00:00 nginx: master process ./nginx
nobody      21    20  0 07:45 ?        00:00:00 nginx: worker process
nobody      22    20  0 07:45 ?        00:00:00 nginx: worker process

配置路由

关闭nginx

./nginx -s stop

xiazhaoyangdeMacBook-Pro:~ xiazhaoyang$ docker ps

修改路由配置

vi nginx.config

[root@56dfba762876 conf]# cd ../sbin/
[root@56dfba762876 sbin]# ./nginx
[root@56dfba762876 sbin]# cd ..
[root@56dfba762876 nginx]# cd conf/
[root@56dfba762876 conf]# vi nginx.conf
[root@56dfba762876 conf]# cd ../sbin/
[root@56dfba762876 sbin]# ./nginx -s stop
[root@56dfba762876 sbin]# ./nginx        
[root@56dfba762876 sbin]#   

server
{
    listen 80;
    server_name localhost;
    index index.html index.htm index.php;
    root /usr/local/nginx/html;

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
    }

   location /docker-registry-web/ {
                proxy_pass   http://192.168.2.102:8000/;
                proxy_redirect default;
        }
   location /jenkins/ {
                proxy_pass   http://192.168.2.102:8002/;
                proxy_redirect default;
        }

}

jenkins通过nginx映射效果

  上图静态资源拉取失败原因：容器内部端口访问不通过本地主机，直接访问资源无法获取，具体原因后续跟进...
