dockerfile部署准备工作

[root@localhost ~]# mkdir apache
[root@localhost ~]# cd apache/
[root@localhost apache]# mkdir files
[root@localhost apache]# touch Dockerfile
[root@localhost apache]# cd files/
[root@localhost files]# wget https://downloads.apache.org/httpd/httpd-2.4.53.tar.gz https://downloads.apache.org/apr/apr-1.7.0.tar.gz https://downloads.apache.org/apr/apr-util-1.6.1.tar.gz

#创建apache目录用于存放源码包和Dockerfile
[root@localhost ~]# tree apache/
apache/
├── Dockerfile
└── files
    ├── apr-1.7.0.tar.gz
    ├── apr-util-1.6.1.tar.gz
    └── httpd-2.4.53.tar.gz

编辑Dockerfile

[root@localhost apache]# vim Dockerfile 
[root@localhost apache]# cat Dockerfile 
FROM centos
  
LABEL MAINTAINER='zjgg 1@2.com'  //标签

ENV apr_version=1.7.0 apr_util_version=1.6.1 httpd_version=2.4.53  

ADD files/* /usr/src/   //将本地files/ 的文件添加到容器内的/usr/src/内

RUN rm -rf /etc/yum.repos.d/* &&   //删除yum仓库内的国外源
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo  && //添加阿里源
yum -y install make gcc gcc-c++ openssl-devel pcre-devel expat-devel libtool libxml2-devel &&
    useradd -r -M -s /sbin/nologin apache &&
    cd /usr/src/apr-${apr_version} &&
    sed -i '/$RM "$cfgfile"/d' configure &&
    ./configure --prefix=/usr/local/apr && make && make install &&
    cd /usr/src/apr-util-${apr_util_version} &&
    ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr &&
    make && make install &&
    cd /usr/src/httpd-${httpd_version} &&
    ./configure --prefix=/usr/local/apache 
    --sysconfdir=/etc/httpd24 
    --enable-so 
    --enable-ssl 
    --enable-cgi 
    --enable-rewrite 
    --with-zlib 
    --with-pcre 
    --with-apr=/usr/local/apr 
    --with-apr-util=/usr/local/apr-util/ 
    --enable-modules=most 
    --enable-mpms-shared=all 
    --with-mpm=prefork && make && make install &&
    sed -i '/#ServerName/s/#//g' /etc/httpd24/httpd.conf

WORKDIR /usr/local/apache  //使用镜像启动容器时 默认目录为apache

EXPOSE 80   //暴露80端口号

ENTRYPOINT /usr/local/apache/bin/apachectl  -DFOREGROUND   //启动容器时默认启动apache并前台运行

制作镜像

[root@localhost apache]# docker build -t zjgg/httpd:v0.1 /root/apache/  //制作镜像
[root@localhost apache]# docker images   //查看镜像
REPOSITORY   TAG       IMAGE ID       CREATED          SIZE
zjgg/httpd   v0.1      93e3dba29a33   16 minutes ago   717MB
centos       latest    5d0da3dc9764   7 months ago     231MB

测试

[root@localhost apache]# docker run -it --rm --name web -p 80:80 zjgg/httpd:v0.1   //用镜像生成容器并映射到宿主机的80端口

[root@localhost apache]# curl 192.168.220.145  //访问
It works!
