拉取centos镜像用centos生成一个容器进去在容器中阿里云的yum源和epel源下载apache的包并复制到容器中


基于容器部署一个web站点

编译安装apache

拉取centos镜像

[root@localhost ~]# docker pull centos:8 8: Pulling from library/centos a1d0c7532777: Pull complete  Digest: sha256:a27fd8080b517143cbbbab9dfb7c8571c40d67d534bbdee55bd6c473f432b177 Status: Downloaded newer image for centos:8 docker.io/library/centos:8 [root@localhost ~]# docker images REPOSITORY   TAG       IMAGE ID       CREATED         SIZE centos       8         5d0da3dc9764   10 months ago   231MB 

用centos生成一个容器进去

[root@localhost ~]# docker run -it --name httpd centos:8 /bin/bash [root@6cd57ac5f6e7 /]#  

在容器中阿里云的yum源和epel源

//yum源配置 [root@44293a537755 /]# cd /etc/yum.repos.d/ [root@44293a537755 yum.repos.d]# rm -rf * [root@44293a537755 yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo [root@44293a537755 yum.repos.d]# sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo //配置epel源 [root@44293a537755 yum.repos.d]# yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm [root@44293a537755 yum.repos.d]# sed -i 's|^#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel* [root@44293a537755 yum.repos.d]# sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel* [root@44293a537755 yum.repos.d]# ls CentOS-Base.repo  epel-modular.repo  epel-testing-modular.repo  epel-testing.repo  epel.repo 

下载apache的包并复制到容器中

//新打开一个终端 [root@localhost ~]# wget https://mirrors.aliyun.com/apache/httpd/httpd-2.4.54.tar.gz http://mirrors.aliyun.com/apache/apr/apr-util-1.6.1.tar.gz http://mirrors.aliyun.com/apache/apr/apr-1.7.0.tar.gz [root@localhost ~]# ls anaconda-ks.cfg  apr-1.7.0.tar.gz  apr-util-1.6.1.tar.gz  httpd-2.4.54.tar.gz [root@localhost ~]# docker cp httpd-2.4.54.tar.gz httpd:/usr/src/ [root@localhost ~]# docker cp apr-1.7.0.tar.gz httpd:/usr/src/ [root@localhost ~]# docker cp apr-util-1.6.1.tar.gz httpd://usr/src/  //在容器中查看是否复制成功 [root@44293a537755 ~]# ls /usr/src/ apr-1.7.0.tar.gz  apr-util-1.6.1.tar.gz  debug  httpd-2.4.54.tar.gz  kernels  //下载相关依赖包 [root@44293a537755 ~]# dnf -y install wget vim openssl-devel pcre-devel expat-devel libtool libxml2-devel gcc gcc-c++ make  //创建一个用户 [root@44293a537755 ~]# useradd -r -M -s /sbin/nologin apache 

编译安装apache

//解压 [root@44293a537755 ~]# cd /usr/src/ [root@44293a537755 src]# tar xf apr-1.7.0.tar.gz  [root@44293a537755 src]# tar xf apr-util-1.6.1.tar.gz  [root@44293a537755 src]# tar xf httpd-2.4.54.tar.gz   //编译apr [root@44293a537755 src]# cd apr-1.7.0/ [root@44293a537755 apr-1.7.0]# vim configure cfgfile=${ofile}T     trap "$RM "$cfgfile"; exit 1" 1 2 15     #$RM "$cfgfile"			//注释这一行 [root@44293a537755 apr-1.7.0]# ./configure --prefix=/usr/local/apr [root@44293a537755 apr-1.7.0]# make && make install  //解压编译apr-util [root@44293a537755 apr-1.7.0]# cd ..

配置环境变量

/配置环境变量 [root@44293a537755 ~]# echo 'export PATH=/usr/local/apache/bin:$PATH' > /etc/profile.d/apache.sh [root@44293a537755 ~]# source /etc/profile.d/apache.sh    //创建头文件 [root@44293a537755 ~]# ln -s /usr/local/apache/include/ /usr/include/apache  //取消启动警告 [root@6cd57ac5f6e7 ~]# vim /usr/local/apache/conf/httpd.conf  ServerName www.example.com:80				//取消注释  //启动apache服务 [root@6cd57ac5f6e7 ~]# apachectl start [root@6cd57ac5f6e7 ~]# ss -anlt State       Recv-Q      Send-Q           Local Address:Port             Peer Address:Port      Process       LISTEN      0           128                    0.0.0.0:80                    0.0.0.0:*                        //验证服务是否能访问 [root@6cd57ac5f6e7 ~]# curl 127.0.0.1 <html><body><h1>It works!</h1></body></html> 

制作镜像

在开启一个终端进行操作

[root@localhost ~]# docker ps  CONTAINER ID   IMAGE      COMMAND       CREATED        STATUS        PORTS     NAMES 6cd57ac5f6e7   centos:8   "/bin/bash"   13 hours ago   Up 12 hours             httpd //-p参数是让正在运作中的容器先暂停等制作完镜像。-c后面跟上的命令是让该镜像作为容器启动时把httpd服务也启用 [root@localhost ~]# docker commit -p -c 'CMD ["/usr/local/apache/bin/httpd","-D","FOREGROUND"]' 6cd57ac5f6e7 xinruizhong/httpd:v1.1 sha256:65836c5507843e93afef9baf8e5dbf8c61b7166a560ff28e8f2fa9a94d4a7fbe [root@localhost ~]# docker images REPOSITORY          TAG       IMAGE ID       CREATED          SIZE xinruizhong/httpd   v1.1      65836c550784   14 seconds ago   789MB centos              8         5d0da3dc9764   10 months ago    231MB  //首次登录需要提供用户名和密码 [root@localhost ~]# docker login Login with your Docker ID to push and pull images from Docker Hub.

测试镜像,并部署网页

//使用创建的镜像创建容器,并挂载存储卷 [root@localhost ~]# docker run -d --name web --restart always -p 80:80 -v /root/httpd_html:/usr/local/apache/htdocs xinruizhong/httpd:v1.1 13a1d5674f411590169702d564522f95f6371e1c702749fc76e17dfa20a2860e [root@localhost ~]# docker ps  CONTAINER ID   IMAGE                    COMMAND                  CREATED         STATUS         PORTS                               NAMES 13a1d5674f41   xinruizhong/httpd:v1.1   "/usr/local/apache/b…"   4 minutes ago   Up 4 minutes   0.0.0.0:80->80/tcp, :::80->80/tcp   web 6cd57ac5f6e7   centos:8                 "/bin/bash"              14 hours ago    Up 13 hours                                        httpd  //导入下载的压缩包,配置网站 [root@localhost ~]# cd /root/httpd_html/ [root@localhost httpd_html]# ls youxi.zip [root@localhost httpd_html]# unzip youxi.zip  [root@localhost httpd_html]# rm -rf youxi.zip  [root@localhost httpd_html]# ls Web.config  from.gif  index.html
