docker学习记录（九）-安装nginx

1、可以通过 docker pull 的方式从镜像源上载入nginx镜像

 

2、通过 Dockerfile 创建镜像

2.1、新建 Dockerfile 文件

[dkuser@c741 ~]$ mkdir centos_nginx

[dkuser@c741 ~]$ cd centos_nginx/
下载nginx包
[dkuser@c741 ~] $ wget http://nginx.org/download/nginx-1.8.0.tar.gz

[dkuser@c741 centos_nginx]$ vi Dockerfile

# From表示使用centos:latest这个镜像为基础构建我们的镜像
FROM centos:latest

# 创建者的基本信息
MAINTAINER xiaozhou (xiaozhou@docker.com)

LABEL Discription="基于centos的nginx镜像" version="1.0"

# put nginx-1.8.0.tar.gz into /usr/local/src and unpack nginx
ADD nginx-1.8.0.tar.gz /usr/local/src

#安装nginx所依赖的包
RUN yum install -y gcc gcc-c++ glibc make autoconf openssl openssl-devel \
&& yum install -y libxslt-devel -y gd gd-devel GeoIP GeoIP-devel pcre pcre-devel \
&& useradd -M -s /sbin/nologin nginx

# change dir to /usr/local/src/nginx-1.8.0
WORKDIR /usr/local/src/nginx-1.8.0

# 编译安装nginx
RUN ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx \
--with-file-aio  --with-http_ssl_module  --with-http_realip_module \
--with-http_addition_module    --with-http_xslt_module  \
--with-http_image_filter_module    --with-http_geoip_module \
--with-http_sub_module  --with-http_dav_module --with-http_flv_module \

&& make && make install

# nginx_config
RUN mkdir /usr/local/nginx/logs && mkdir /usr/local/nginx/run \
&& sed -e '3i\user nginx;' -i /usr/local/nginx/conf/nginx.conf \
&& sed -e "9i\error_log /usr/local/nginx/logs/error.log;" -i /usr/local/nginx/conf/nginx.conf \
&& sed -e "12i\pid /usr/local/nginx/run/nginx.pid;" -i /usr/local/nginx/conf/nginx.conf \
&& sed -e "29i\ \taccess_log /usr/local/nginx/logs/access.log;" -i /usr/local/nginx/conf/nginx.conf

# logrotate
RUN touch /etc/logrotate.d/nginx \
&& echo -e "$LOGS_DIR/*.log {" >> /etc/logrotate.d/nginx \
&& echo -e "\tdaily" >> /etc/logrotate.d/nginx \
&& echo -e "\trotate" >> /etc/logrotate.d/nginx \
&& echo -e "\tmissingok" >> /etc/logrotate.d/nginx \
&& echo -e "\tdateext" >> /etc/logrotate.d/nginx \

&& echo -e "\tendscript" >> /etc/logrotate.d/nginx \
&& echo -e "\t}" >> /etc/logrotate.d/nginx

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

EXPOSE 80

CMD /bin/sh -c 'nginx -g "daemon off;"'

 

2.2、执行创建镜像命令

[dkuser@c741 centos_nginx]$ docker build -t centos_nginx .

.......

make[1]: Leaving directory `/usr/local/src/nginx-1.8.0'

Removing intermediate container 2471c1cc8e93

 ---> dcd18de4a1c9

Step 16/16 : EXPOSE 80

 ---> Running in e80691a08812

Removing intermediate container e80691a08812

 ---> 3a69ebee9a56

Successfully built 3a69ebee9a56

Successfully tagged centos_nginx:latest

 

查看镜像

[dkuser@c741 centos_nginx]$ docker images

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

centos_nginx        latest              3a69ebee9a56        52 seconds ago      745MB

 

3、运行容器

[dkuser@c741 centos_nginx]$ docker run -dit -p 80:80 centos_nginx

 

参数说明：

-d 后台运行

-i 交互模式

-t 分配tty设备，支持终端登录

 

4、登陆容器

[dkuser@c741 centos_nginx]$ docker attach objective_banzai

 

查看文件

[root@8b534d79f7c5 nginx-1.8.0]# ll

拷贝启动脚本，启动nginx

[root@8b534d79f7c5 nginx-1.8.0]# mkdir sbin

[root@8b534d79f7c5 nginx-1.8.0]# cp objs/nginx sbin/ 

 

[root@8b534d79f7c5 nginx-1.8.0]# cd sbin

[root@8b534d79f7c5 sbin]# ./nginx 

 

访问nginx

[root@8b534d79f7c5 sbin]# curl http://localhost:80

<!DOCTYPE html>

<html>

<head>

<title>Welcome to nginx!</title>

<style>

    body {

        width: 35em;

        margin: 0 auto;

        font-family: Tahoma, Verdana, Arial, sans-serif;

    }

.....

 

注意：

不要使用 exit 和 ctrl + D 退出容器，因为这样会停止容器的运行，可以使用 ctrl + P + Q 退出容器

 

5、宿主机访问nginx

[dkuser@c741 centos_nginx]$ curl http://localhost:80

<!DOCTYPE html>

<html>

<head>

<title>Welcome to nginx!</title>

<style>

    body {

        width: 35em;

        margin: 0 auto;

        font-family: Tahoma, Verdana, Arial, sans-serif;

    }

</style>

</head>

.....

 

6、浏览器访问nginx
